Update 8/16/21 5:30am PT: Crucial has swapped out the TLC flash that powered the initial P2 SSD we tested with QLC flash, severely reducing performance. We've written an investigation into that matter, which you can read here, with our results showing that the 'new' drives are nearly four times slower at transferring files than the original, read speeds are half as fast in real-world tests, and sustained write speeds have dropped to USB 2.0-like levels of a mere 40 MBps. That’s slower than most hard drives. Unfortunately Crucial made the change without altering the product name or number or issuing an announcement. Crucial claims that the P2 will live up to its specs because the company baked the performance of QLC flash right into the spec sheet at launch. But those specs don’t match the performance you’ll see in numerous reviews of the originally-shipping drives.

As such, we do not recommend purchasing this drive — instead, consult with our latest recommendation in our Best SSDs article. In this article, we have also inserted additional albums in each test category to reflect the real performance you'll get when purchasing this drive today. 

Original article:

Crucial’s P1, the company's first M.2 NVMe SSD, was a bit of a disappointment with slow performance and among the lowest endurance specifications on the market. It surely didn’t scream value as we had hoped it would. Crucial’s new P2 aims to be a better value with Phison’s entry-level E13T NVMe SSD controller and Micron’s latest 96-Layer TLC flash under the hood, though. Crucial’s P2 may not be the Best SSD on the market, but it offers multi-gigabyte throughput at low price points, blowing SATA SSDs out of the water. 

The SSD market is quite crowded, and if you’re on the hunt for a new SSD for your system, you probably notice there are innumerable options. If you’ve got the dough, you may want to consider one of the newest PCIe 4.0 x4 options, say the Seagate FireCuda 520 or Sabrent’s Rocket NVMe 4.0. But, if you’re a bit strapped for cash, then one of the many low-cost SSDs, like Crucial’s MX500 or P1, might be up your alley…until you suddenly realize that Crucial’s new P2 is now available, potentially offering significantly more performance at the same price. Overall, the P2 is perfect for a cheap M.2 NVMe boot drive, making it a clear contender for the top spot among value SSDs, but it appears Crucial will make the drive with a variable build of materials, meaning the internal components could change over time. That means you'll need to do your research before you plunk down your hard-earned dollars.

Crucial’s P2 is the company’s latest M.2 NVMe SSD for the low-budget crowd. In fact, the P2’s pricing might cannibalize the company’s MX500 sales just as much as it competes with other companies. The 250GB and 500GB capacities are well-suited for basic boot and application requirements, but although Crucial lists a 1TB SKU, it isn’t available at the time of publishing. The entry-level P2 SSDs are priced at $50 for the 250GB model and just $65 for the 500GB model, though. 

The P2 features Dynamic Write Acceleration, which essentially programs a pool of TLC flash as faster SLC for faster write performance. After it fills, write performance will degrade, which we will cover in greater detail on the next page. Crucial rates the P2 to deliver sequential performance of up to 2.4/1.8 GBps read/write and up to 170,000/260,000 read/write IOPS, but performance suffers a bit with the smaller 250GB and 500GB capacities. The 500GB’s sequential write performance is even rated below the 250GB model at just 940 MBps. 

The drives come with RAID ECC and Phison’s fourth-gen LDPC that has multiple levels of adaptation. As a result, Crucial’s P2’s endurance ratings, though they are low for TLC SSDs, aren’t as offensive as some of the QLC SSDs we’ve looked at. The company rates the 250GB P2 up to 150TB of writes within its five-year warranty, and adds another 150TB of write endurance with each doubling of capacity. 

Crucial P2 Software and Accessories

The drives come with Crucial’s SSD Toolbox, Storage Executive, and Acronis True Image (via download). Crucial Storage Executive is quite handy and feature-packed. With it, you can optimize performance, manage data security, or even just update the firmware, among other features. Acronis True Image for Crucial lets you clone your data or make system images for free as long as you have a Crucial SSD plugged in, but some of the backup features aren’t included unless you buy the full version. 

A Closer Look at the Crucial P2

The Crucial P2 comes in an M.2 2280 form factor. The PCB is black, but the quality of the finish is rather lacking. The edges of the M.2 board are rough, and unlike other SSDs, the black finish doesn’t make it all the way to the edges..

The P2 interfaces with the host over a PCIe 3.0 x4 link with the Phison E13T, a DRAMless 4-channel NVMe 1.3 SSD controller. Phison fabs the E13T on the 28nm process node and the chip operates at 667MHz. The controller is a single-core design with a coprocessor optimized for NAND management task offloading. Speaking of which, there are four NAND packages on our 500GB P2, with 9% set aside as factory overprovisioning for background tasks like bad block management and garbage collection. Each package contains two dies of Micron’s latest 512Gb 96-Layer TLC flash that interface with the Phison E13T NVMe controller at 800MT/s. 

The P2 lacks DRAM, meaning that it doesn’t have a fast buffer space for the FTL mapping tables. Instead, the P2, like most modern DRAMless NVMe SSDs, uses NVMe’s Host Memory Buffer feature. With it, the SSD can use a few MB of the host system’s memory to provide snappier FTL access, which improves the feeling of ‘snappiness’ when you use the drive.

Additionally, the controller supports APST, ASPM, and L1.2 power saving modes for better power efficiency in mobile devices. There’s an adaptive thermal throttle protection built-in, so if the controller and NAND get too hot (70 degrees Celsius), the SSD will throttle performance or even shut down (85C), so it doesn’t damage data. Furthermore, the P2 comes with integrated power loss ‘immunity,’ so data is fairly protected in the case of a power outage. The controller also supports S.M.A.R.T. data monitoring, TRIM, and secure erase capability to completely wipe the data clean off it, too.

    The performance doesn't look particularly good, generally being at the bottom of the barrel among the NVMe drives, and even seeing a 23% longer load time than the SATA-based MX500 at the Final Fantasy test. If it's 23% slower than a SATA drive at actually loading things, and 30% slower than the previous P1 model, then what's the point? Higher sequential transfers in some synthetic benchmarks and file copy tests don't mean much if it's going to perform worse at common real-world operations. I certainly wouldn't say that the drive "beats SATA dollar for dollar" or "delivers SATA-breaking speed, even without DRAM" based on those results.

    The indications that QLC flash may be replacing the drive's TLC in a future revision also means the P2 might perform substantially worse than the results shown here, so I hope to see some follow up testing if that ends up being the case. The review says the BX500 did that, and mentions "keeping us up to date" about it, but if I search for BX500 reviews, including the one from Tom's Hardware, they all appear to describe the drive as using TLC and performing better than the drive's specifications would indicate, and no update appears to have been made about the switch to QLC. Sending out faster TLC drives for review, then releasing versions with QLC under the same product name at a later date seems rather shifty.

    Under light operation, Crucial’s P2 offers a snappy and responsive user experience that will surpass any SATA SSD. It trades blows with Silicon Power’s P34A60 and even keeps up with the Samsung 970 EVO Plus, yet gets beat in both the Quick and Full System benchmarks by both of the drives. Crucial’s P1, with its DRAM-based architecture, outperforms both the P2 and P34A60. That proves that DRAM-based designs provide the most responsive user experience, even with slower QLC flash.
    As far as a "responsive user experience" goes, something tells me that these differences of a few millionths of a second are not going to be perceptible. The difference in latency between the fastest and slowest SSD tested here only amounts to around one ten-thousandth of a second, so I don't see how anyone would notice that when it will take a typical monitor around a hundred times as long to update the image to display the output. Maybe a bunch of these operations added together could make some difference, but then more of the drive's performance characteristics will come into play than just latency, so I don't see how that synthetic benchmark would bear much direct relation to the actual real-world experience. It's fine to show those latency benchmark results, but I don't think direct relations to the user experience can really be drawn from them.

    I'd like to see more real-world load time results in these reviews, as that's what these drives will typically be getting used for most of the time. As the Final Fantasy test shows, just because one drive appears multiple times as fast in some synthetic benchmarks or file copy tests, that doesn't necessarily translate to better performance at actually loading things. Practically all of the synthetic benchmarks show the P2 being substantially faster than an MX500 SATA drive, but when it comes to loading a game's files, it ends up being noticeably slower by a few seconds. Is that result a fluke, or are these synthetic tests really that out-of-touch with the drive's real-world performance? These reviews should measure other load times of common applications, games and so on, and not just rely primarily on pre-canned and synthetic benchmarks that seem to be at odds with the one real-world loading test.

    Also, I'd like to see test results for drives that are mostly full. Does the real-world performance tank if the drive is 75% or 90% full, and less space is dedicated to the SLC cache? These benchmark results don't really provide any good indication of that. The graphs showing how much performance drops once the cache is filled are nice, but the size of that cache will typically change as the drive is filled. A mostly-full drive may only have a handful of gigabytes of cache that gets filled even with moderately-sized write operations.

    The P2 lacks DRAM, meaning that it doesn’t have a fast buffer space for the FTL mapping tables. Instead, the P2, like most modern DRAMless NVMe SSDs, uses NVMe’s Host Memory Buffer feature. With it, the SSD can use a few MB of the host system’s memory to provide snappier FTL access, which improves the feeling of ‘snappiness’ when you use the drive.
    A "few MB" is kind of vague. How much system RAM is it actually using? The Crucual P1 had 1GB of DRAM onboard for each 1TB of storage capacity. If the P2 is using 1GB of system RAM for the same purpose, then that's a hidden cost not reflected by the price of the drive itself. This might be especially relevant if one were adding such a drive to a system with just 8GB of RAM. And even on a system with 16GB, that could become more of a concern within a few years as RAM requirements rise for things like games. If one ends up needing to upgrade their RAM sooner due to DRAMless drives consuming a chunk of it, then the cost savings of cutting that out of the drive itself seems questionable, especially given the effects on performance.

    And for that matter, it seems like the performance of system RAM could affect test results more than it does on drives with their own onboard RAM. I'm curious whether running system RAM at a lower speed, or perhaps on a Ryzen system with different memory latency characteristics could affect the standings for these DRAMless drives. The use of system RAM also undoubtedly affects the power test results as well. This drive appears to be among the most efficient models, but is the system RAM seeing higher power draw during file operations in its place?

    Unfortunately, I don't have one. But, the P1 is very close in performance - so close it is almost a substitute if you want to see how the 660p 512GB may perform.

    Updates I am referring to typically come in news posts or if I am sampled the updated device, it will be reflected in an update in the review. I wasn't aware of the BX500 QLC swap until recently, the week of writing this review, and actually haven't had a moment to notify the team about it until the other day, tho I think I saw a post about it somewhere at one point.

    As far as a "responsive user experience" goes, something tells me that these differences of a few millionths of a second are not going to be perceptible. The difference in latency between the fastest and slowest SSD tested here only amounts to around one ten-thousandth of a second, so I don't see how anyone would notice that when it will take a typical monitor around a hundred times as long to update the image to display the output.

It's fine to show those latency benchmark results, but I don't think direct relations to the user experience can really be drawn from them.

    After toying with hundreds of SSDs, for me, I notice the difference in responsiveness between SATA and PCIe SSDs in day to day use. It's slight but noticeable, and especially so when launching apps after boot and moving a bunch of files around. You may not be able to draw conclusions by only looking at synthetic, but that doesn't mean one can't.

    The iometer and ATTO synthetic data are just a few of the data points I look at when analyzing performance. But, there are some relationships/patterns in these data points metrics that carry over to real-world performance. After analyzing the strengths and weaknesses between many SSDs architectures and performance scores and operation habits in the same system, one can start linking synthetic differences between devices to real-world experience differences between devices. As well, these results are included to validate manufacturer performance ratings. Real-world benchmarks can not do that, which is why I include them as supporting evidence to complement the real-world data.

    I'd like to see more real-world load time results in these reviews, as that's what these drives will typically be getting used for most of the time. As the Final Fantasy test shows, just because one drive appears multiple times as fast in some synthetic benchmarks or file copy tests, that doesn't necessarily translate to better performance at actually loading things.

These reviews should measure other load times of common applications, games and so on, and not just rely primarily on pre-canned and synthetic benchmarks that seem to be at odds with the one real-world loading test.

    The only synthetic tests that I use are iometer and ATTO. PCMark 10 and SPECworkstation three are trace-based that test the SSD directly against multiple real-world workloads that cater to their respective consumer and prosumer market segments.

    Final fantasy shows just a second or two difference because of a few reasons. Most SSDs are similarly responsive to this one workload simply because it isn't a demanding one, it is a rather light read test really. Overall, the game data loading process is so well optimized for HDD usage that when you replace the HDD with the SSD, most will load the few hundred GB of data per game scene at relatively the same time since its such a small transfer.

    The fastest SSDs can respond faster to the random and sequential requests than others due to lower read request latency, and thus they rank ahead of slower ones here - those few hundredths of an ms add up to show that difference. Ideally, I need a larger, more graphically demanding game benchmark, a better GPU, and a 4K monitor to get a larger performance delta between drives. Different resolution settings and games will perform differently. I use Final Fantasy's benchmark because it is the only one I know of that saves load time data. I hope more devs could include load times in their game benchmarks. If you have any recommendations, I'm all ears!

    Also, I'd like to see test results for drives that are mostly full. Does the real-world performance tank if the drive is 75% or 90% full, and less space is dedicated to the SLC cache? These benchmark results don't really provide any good indication of that. The graphs showing how much performance drops once the cache is filled are nice, but the size of that cache will typically change as the drive is filled. A mostly-full drive may only have a handful of gigabytes of cache that gets filled even with moderately-sized write operations.

    Ah yes, more write cache testing, my favorite! I could do more and it would be cool to include, but it is not worth doing so at this time. Most dynamic SLC write caches will shrink at a higher full rate, but most perform well still. I perform all my testing on SSDs that are running the current OS and 50% full as it is (except the write cache testing is done empty after a secure erase when possible). Most of the time, even though the cache shrinks, it's still as responsive as when the drive was empty, the write cache is smaller in size so only larger transfers will be impacted.

    A "few MB" is kind of vague. How much system RAM is it actually using? The Crucual P1 had 1GB of DRAM onboard for each 1TB of storage capacity. If the P2 is using 1GB of system RAM for the same purpose, then that's a hidden cost not reflected by the price of the drive itself.

If one ends up needing to upgrade their RAM sooner due to DRAMless drives consuming a chunk of it, then the cost savings of cutting that out of the drive itself seems questionable, especially given the effects on performance.
    Unfortunately, I do not have tools that tell me exactly how much each drive utilizes and manufacturers will not disclose specifics all the time...well I might have a tool, but I haven't been able to explore using it quite yet. From the drive's I have tested with HMB and had the RAM usage disclosed to me, it has been set to around 32-128MB. However, based on some discussion with a friend, we think it could be up to 2GB-4GB based on the spec's data

    And for that matter, it seems like the performance of system RAM could affect test results more than it does on drives with their own onboard RAM. I'm curious whether running system RAM at a lower speed, or perhaps on a Ryzen system with different memory latency characteristics could affect the standings for these DRAMless drives. The use of system RAM also undoubtedly affects the power test results as well. This drive appears to be among the most efficient models, but is the system RAM seeing higher power draw during file operations in its place?

    All testing is currently on an Asus X570 Crosshair VIIIHero (Wifi) + Ryzen R5 3600X @4.2 all core platform with a kit of 3600MHz CL18 DDR4. I actually have that suspicion myself and have been planning to get a faster kit of RAM to test out how it influences both DRAMless and DRAM-based SSD performance, too.

    Price looks good. But I prefer to keep price lanes open for things that really need it, like GPUs, and run an SSD from the SATA port.

    Yeah, I know those test suites are based on real-world software, but it's a bit vague exactly what operations each test is based on and how those apply to different workloads in the real world, so they might as well be synthetics. With CPU and graphics card reviews, you tend to see much more of a focus on testing actual software in ways that make it relatively clear what each test is comprised of.

    The Final Fantasy test usually seems to be relatively in line with typical measurements of NVMe vs SATA vs HDD performance as far as game loading is concerned, but the results for this drive seem a bit off, with it not even matching the MX500, despite practically all the other benchmarks in the review saying it should perform better. Maybe its a result of being DRAMless? If the game is heavily utilizing the CPU and RAM during the loading process, perhaps it's fighting with the drive for access to system memory? It might be something worth investigating further.

    I'm not really sure about any demanding games that include load time readouts. However, there could be other methods. For example, recording video of games loading with an external capture device and using the resulting video file to check how long loading took, though I can see how that might make testing a bit inconvenient. Or maybe just using a graph of disk access to check that, which would likely work reasonably well for at least some titles. There wouldn't necessarily need to be a lot of tests, but having a few might prevent any one from making a particular drive appear better or worse than might typically be the case.

    They are based on real-world system interaction and are traces that are exactly the same on each SSD. It is up to the storage device to differentiate itself when running those exact same workloads. There is some more detailed data in the results, but the time to spend on graphing out the details isn't. Most of the data shows similar to the rankings already graphed anyways. For more knowledge, you can read through the benchmark technical guides for more detailed information on how the tests run and how scoring is calculated. Storage tests are near the bottom of the tech guide.

    Yes, entirely so. The firmware and HMB on Phison's E13T's optimized for write performance while Silicon Motion's SM2263XT's firmware and HMB is optimized for reading. Going from SSD controller though the PCIe lanes, to host memory for the buffer, and then, back to the controller adds a bunch of latency. Which is why the write-optimized E13T can't keep up in reading tasks, it is ready to respond to write requests more than it is ready to respond to read requests.

    An M.2 PCI-E drive are not going to affect your top GPU slot, unless said board has a very weird configuration. Typically an M.2 will disable sata ports, or PCI-E slots that most people never really use much anyway. SLI/CF is dead, as well.

    I run multiple GPUs, so PCIE lanes are still in short supply.
    For my purposes, I prefer to have PCIE 3.0 x8 slots, but can do with x4 lanes too.
    I use 3 GPUs, the max the motherboard supports.
    On an MSI MPG board i have, that means an x8/x8/x4 configuration, or 20 out of the 24 lanes.
    On other boards, I can only do x8/x4/x4 (or 16 lanes).
    In both cases that leaves either zero or 4 lanes left for (m.2) PCIE SSDs.

    The top M.2 slot gets its lanes, from the CPU, at least on the AMD side of things. You get 16 lanes for GPU, 4 for M.2 NVME storage, and 4 that connect to the chipset. Any other M.2 is going to get it PCI-E lanes from the chipset. I am not aware of any current board that has a PLX chip, for more lanes. What lanes give what, with regards to M.2 and GPU lanes, beyond the top GPU and M.2, are dependent on chipset, and then how the board manufacturer decided to implement the lanes, they have to deal with.
