Sequential Read

Regardless of whether it's complemented by MLC or TLC NAND, Phison's S10 controller blows through large-block sequential workloads. Both the MyDigitalSSD BP5e and Klevv Urbane utilize Toshiba flash. The Urbane comes armed with MLC on a Toggle-mode 2.0 interface, so you'd expect it to be faster. Don't tell that to the BP5e, though, because it's at the top of our chart in this test.

Sequential Write

High performance that maxes out the real-world limits of SATA 6Gb/s carries over to our sequential write test, too. The BP5e doesn't waver much in this benchmark, which is something we often see from TLC-based SSDs.

Random Read

A high entropy rate (that means incompressible data) causes the BP5e's random read performance to suffer. It doesn't help that many of the drives on this chart are higher-end models. There simply aren't a lot of products in the low-cost segment to compare a 960GB BP5e.

Random Write

The BP5e demonstrates weak 4KB random write performance across the queue depth range. It doesn't scale well in our test, mainly because the emulated SLC buffer doesn't get much time to recover. As we see more inexpensive TLC-based drives, we'll look at revising our testing methods to let the buffer replenish fresh cells.

  • That price is incredible. I remember my first SSD, when it was ONLY 2$/GB. If I was buying today, I'd get 6 * 480 GB drives, and run them in a btrfs raid, just for plain storage. For anyone buying today, for their own use, it makes no sense to go mechanical.

    Can't wait for the next generation Samsung 3d nand.

    It makes no sense to raid 0 SSD's, you won't improve random 4k performance AND YOU WONT IMPROVE LATENCY (wich is what it makes SSDs faster than a HDD). You're simply adding more fail %.

    NVMe SSD's barely improve those things. We will need intel's 3D Xpoint (or similar tech) for another massive gain in those things.

    The price might be relatively good for an SSD, but that's still 25 cents per gigabyte. Mechanical desktop drives, by comparison, are generally around 3 to 5 cents per gigabyte, which for someone needing multiple terabytes for bulk storage or backup redundancy can really add up. For many purposes like storing video, there won't be much of a performance difference either.

    Of course, most people probably don't even need 1 TB of storage in their system, and 240 GB of storage could be more than enough for them, in which case doing away with a mechanical drive in favor of a comparably priced but lower-capacity SSD could make a lot more sense.

    Interesting to see TLC continuing to lead the value market with further refinement of error correction technique while still developing improvements in performance.

    As a REVIEW, it comes up short in evaluting against products in the same performance and price segment. As I started to read the review, I kept looking for Tom's Best Pick 1TB Budget Buy, the Mushkin Reactor, to be included. And, there are also other TLC based drives, that Tom's has reviewed in other capacities, that should be included. In my mind, the review should have included at a minimum: Samsung 850 EVO 1 TB (as the TLC performance reference), ADATA SP550 960GB, and Mushkin Reactor 1TB. At this point in time, the MyDigitalSSD, ADATA and Mushkin drives are competing at the same price point on Amazon and Newegg. Comparing these drives would have brought more meaning to the review.

    Nintendork,
    There are reasons to RAID0 an SSD. For example, working with video can benefit. Plenty of articles with number to prove that, and also to prove that for MOST things real-world benefits aren't there.

    How likely is it that other Phison S10 drives have benefited significantly from performance-related firmware updates since release? It seems like this drive is better than the competition primarily because of the more mature firmware, but I'm wondering if other drives have also improved since release.

    When Adata released the SP550 drives for review the 960GB model was not ready. We simply do not have that drive. We built a low cost SSD performance database for each of the other capacity sizes and you see similar products grouped together in those reviews. From Computex (last June) until only recently many of the TLC-based drives were not available. In short, we're working on it.

    This review was put together before the OCZ Trion 150 arrived, the two new PNY drives, the new Corsair LE and the stuff we can't talk about yet (but soon).

    The Best of Monthly (what I call it) goes back to being a monthly release starting this week. Several of you read and comment on my reviews so you are here quite a bit. I plan to utilize the monthly column to recap the reviews for the month and give some insight into what to expect for the next month. I've also added several new columns. Expect to see entry-level, mainstream, and premium drives for each capacity as well as new PCIe and All-in-One RAID drives.

    Minimal price reduction for a massive reduction in write endurance. It is a bad value unless they can reduce their price by at at least 40% (to match the data density gains that they get from TLC).

    Even though - good job! The review is useful and one gets a nice overall view. Thank you. :)

    May I ask for your personal opinion? As a budget 1TB SSD - would you buy Mushkin Reactor 1TB, MyDigitalSSD BP5e 960GB, Adata SP550 960Gb, or wait for new releases (or wait even until june)?

    I hope "mydigitalssd" has finally gotten their stuff together. I bought a BP4e mSATA drive about a year or so ago. It failed constantly. I contacted "mydigitalssd", RMAed the drive. MDSSD replaced the drive. The replacement drive has the same issues.
    There is a cost/benefit that needs to be taken into account when dealing with drives. This is a low cost option,however do you really want to take the chance? I am sorry i did.
