Power Up Your Storage

Silicon Power has saddled its latest SSD with the fairly generic moniker of PCIe Gen3x4, so we'll be referring to it by part number, P34A80, instead. Today we’re testing the 1TB capacity and at this size, performance is quite impressive. With rated 3.4/3 GBps sequential read/write speeds, this snappy little guy will speed up your system without a doubt, and it's cheaper than most of its competition.

Silicon Power’s P34A80 features Phison’s E12 NVMe controller, paired with Toshiba’s BiCS3 64L TLC NAND flash. Just as with many of the SSDs we have seen with this combination of components before it, like the the MyDigitalSSD BPX Pro, the P34A80 is quite the capable device. Aside from the impressive rated sequential speeds, it also sports up to 390K and 450K IOPS read and write on our 1TB sample.

The P34A80 is available in capacities from 256GB to 1TB at this time. The company has a 2TB SKU, which Silicon Power says will be available sson. At 109.99 for our 1TB sample, or just $0.11 per GB, this drive is quite affordable. The 512GB and 256GB models aren't that much pricier, at $0.12 and $0.15 per GB respectfully. At these prices, the Silicon Power P34A80 simply screams value, and should be a top consideration if you're concerned about balancing speed and price.

The Silicon Power drive comes with all the performance you could ask for from a high-end TLC based SSD, and  at a similar cost to those QLC based SSDs like the Intel SSD 660p and Crucial P1. What’s not to love?

Well, in order to bring such low prices to the market, there were some corners that Silicon Power cut. Luckily for consumers, there are no deal-breakers. While not officially stated on their website at this time, the P34A80 does come with endurance ratings. Typically, we would expect endurance ratings of ~380TBW, 800TBW, and 1700 TBW for the 256GB, 512GB, and 1TB Phison E12 powered devices. But Silicon Power seems to be more conservative in their ratings.

The 256GB model is rated for up to 125TBW, and this figure doubles as capacity doubles, meaning 250 TBW on the 512GB model and 500 TBW of endurance on our 1TB model. This is low for a TLC drive, but most don’t write more than 20GB-30GB of data a day to their devices, so running out of endurance isn’t as likely as you running out of warranty time first. Speaking of which, the Silicon Power P34A80 comes backed by a 5-year warranty, rather than a 3-year warranty like some of the other Phison E12 based SSDs we have reviewed recently.

As well, the P34A80 boasts standard features like S.M.A.R.T. data reporting, TRIM, and support for Format NVM /secure erase commands, but does not come with OPAL or Windows BitLocker support.

Software and Accessories

Silicon Power has an SSD toolbox available for download on their website. You can use it to monitor your device's health, performance, and even secure erase. But at the time of writing, V3.0.1.0 doesn’t seem to support the P34A80.

A Closer Look

Silicon Power’s P34A80 comes in an M.2 2280 form factor. Our 1TB sample is double-sided, meaning components are on both sides of the PCB. Unlike most M.2 SSDs out now, the PCB isn’t black, instead, it is blue. The company threw a dark sticker over top of the drive, but with a scan code and other distracting elements on it, it is well…rather distracting. Something labeling the opposite side would easily remedy.

As mentioned earlier, the Phison E12 NVMe controller is powering this SSD and there are four Toshiba BiCS3 NAND packages in all. Also, there are two 512MB DDR4 DRAM package for the controller to use for caching the File Translation Layer (FTL). Once formatted in Windows, the end user has 953GB of free space to use.

    It seems Silicon Power is grossly conservative with the endurance rating. Similar drives have dramatically higher published endurance ratings. I would assume the same nand and same controller would have the same, or very similar, endurance. This is indeed the case with other E12/bics3 nand drives. The BPX Pro and MP510 are identical hardware with over-provisioning have ~1700TBW/960GB. Inland Premium (Microcenter house brand) is same hardware without any over-provisioning has a 1600TBW endurance for a 1TB drive.

    Its hard to believe the Silicon Power P34A80 has less than a third of the endurance of other drives featuring the exact same hardware.

    Where does the meager 125TBW/256GB endurance rating come from? It doesn't appear that Silicon Power published an endurance number on their website.

    Sabrent Rocket is another budget E12/bics3 drive with a rating of 1665 TBW/1TB.
    TEAM GROUP MP34 is also rated at 1665 TBW/1TB.

    Five other drives with the E12/bics3 all have 1600+ TBW for a 1TB class drive.
    Hard to believe that the Silicon Power only has 500TBW/1TB

    I would guess that it has to do with limiting their liability. The endurance ratings come directly from the company after my inquiry.

    It seems quite likely the Silicon Power endurance information is erroneous. How could one explain that of the six drives mentioned, all with Phison E12 controller and BICS3 NAND, five have 1600+TBW ratings and one has a 500TBW rating. Logic would suggest the 500TBW rating is simply wrong.

    I contacted their tech support, they said the 2TB model has an endurance of 3115TB.

    According to the review, this disk should ensure AES encryption. How to start using it/set password? Is that executed through disk password in BIOS? Have anyone succeded in setting this? If yes in what laptop?

    Ok, I've received the answer from Silicon Technology and... they are saying that this disk is NOT supporting any encryption. As I was furious and very confused I've asked them once again and they answered the same saying that they confirmed this twice with engineers. So forget about hardware encryption guys.....

    I have this and I am returning it for incompatibility reasons.
    it's like this , every ssd Nvme Pcie I have reports as 512 sector the brands are Crucial and Samsung yet this reports as 4096 regardless of the enclosure you put it in as I also found out that all enclosures use the same chipset .It means you can't clone to this drive because it does not use 512e it's 4kn and that is the way it stays .
    I'm going back to Samsung at least I know I can clone to their drives because of the chipset they use which is different from the Silicon power chipset.
    It's something you should be aware of as I have dragged the internet looking for some meaningful advice but in the end nobody knows , so just be aware you can't change the sector size and it will always report as 4096 because of the controller.

    Interestingly, there are tools out there to change that tho. Have you emailed them? I know Sabrent has one for their E12-based SSDs. You can also use your motherboard's built-in secure erase tool to switch between 512e and 4K sectors if it has one. What software are you using? Ideally, it should be able to clone over the data regardless of source and destination sector sizes, it seems tho that the software is lagging support for the hardware here.

    Amazon reviews on the Silicon Power P34A80 report that the Toshiba NAND has been replaced by a UNIC branded package and that the Hynix DDR4 DRAM has been replaced with Nanya DDR3.

    I would think that the expected performance from DDR3 would be less.

    - From Zaphod_"How could one explain that of the six drives mentioned, all with Phison E12 controller and BICS3 NAND, five have 1600+TBW ratings and one has a 500TBW rating. Logic would suggest the 500TBW rating is simply wrong."

    Bait and Switch was probably planned and explains the extremely conservative endurance numbers put out.

    My guess is that Silicon Power's P34A60 reviewed with Intel NAND will probably also be subbed for brand-Xi chips.

    I have been shopping for a new boot/main drive and this is the second drive I have been very close to buying only to find that the drive for sale is not the same as the drive reviewed and compared to the competition. I was looking at buying the highly rated XPG SX8200 Pro recommended here at Tom's but found that recent purchaser's found that the expected Micron NAND had been replaced by UNIC branded chips and I saw that the production location listed had changed from "Made in Taiwan" to "Made in China".

    I expect that businesses will switch suppliers and that they will cut corners to cut costs. I know a "Bait and Switch" is just a traditional, if dishonest and dirty, sales tactic.

    Sometimes a dishonest business tactic is a small part of a larger aggressive totalitarian state run pattern of abuse that has real and serious consequences.

    From Anandtech - Yangtze Memory Technologies Co. and UNIC Memory Technology belong to Tsinghua Unigroup, a government-controlled high-tech conglomerate from China.

    Anyway now looking at the Crucial P5 or WD SN550. I feel like I'm more likely to be getting what i think I'm getting.

    Both the XPG and this Silicon Power SSD are still on the Best SSDs of 2020 but are not the same product that was tested. I think they should be retested as currently sold.
