Silicon Power 1TB NVMe PCIe Gen3 x4 M.2 2280 TLC R/W up to 3,400/3,000 MB/s SSD (SP001TBP34A80M28)

Pros: Works as advertised Inexpensive Phison E12 controller Toshiba 64 layer TLC NAND Outstanding write endurance (5 year warranty) 512 GB... A little more space than comparable Corsair MP510, and MDSSD BPX Pro

Cons: None

NOTE ON LOW WRITE SPEEDS I noticed that after a hard reset (black screen from overclocking), this drive would not write at full speeds (CrystalDiskMark Seq. Write 640 MB/s). I believe this was due to Windows 10 disabling write caching on the drive. Here is how I corrected the problem. Open: Device Manager> Disk Drives> SPCC M.2 PCIe SSD> SPCC M.2 PCIe SSD Properties> Policies In Policies, toggle both boxes "Enable write caching on the device", and "Turn off Windows write-cache buffer flushing on the device" (toggle a few times). MAKE SURE BOTH BOXES ARE CHECKED and click "OK". Keep Device Manager open and run your benchmark to see if write speeds are back to spec. If everything is good, go back into: SPCC M.2 PCIe SSD Properties> Policies UNCHECK BOX "Turn off Windows write-cache buffer flushing on the device" (so as to not have a power outage corrupt Windows). Click "OK". Run your bench again to see if drive is still up to spec. Good luck on your mission, Jim. :) P.P.S. Bought a second one for my daughter's new computer, and it works just as well as the first one.

Pros: No installation issues Works as intended Read/write speeds match specs Not DOA

Cons: No sticker with the packaging for my collection

Overall Review: Easy install, detected on the first boot, value seems unmatched at this time.

Pros: Installed flawlessly on my AMD Ryzen 3600 / MSI Tomahawk Max system. Linux Udisks utility benchmark gave whole disk 3.4G read speed with 70 microseconds latency. On actual partitions with file system overhead this drops to 2.4G, still very respectable figure. as a NVME disk, regular SMART monitoring applications won't recognize it. On Linux Mint, I installed nvme-cli (in the software manager), then typed: 'sudo nvme list' to get the name of the drive then 'sudo nvme smart-log /dev/nvme0n1' to see the equivalent of SMART report.

Cons: The disk worked well but was showing lots of kernel errors in /var/log/syslog Oct 15 16:28:15 ******* kernel: [ 88.172669] nvme 0000:01:00.0: PCIe Bus Error: severity=Corrected, type=Data Link Layer, id=0100(Transmitter ID) Oct 15 16:28:15 ******* kernel: [ 88.172675] nvme 0000:01:00.0: device [1987:5012] error status/mask=00001000/00006000 Oct 15 16:28:15 ******* kernel: [ 88.172678] nvme 0000:01:00.0: [12] Replay Timer Timeout No one really likes hardware errors on their system even if that's just timeouts that are recovered from. The first thing I tried was to throttle PCI from Gen3 to Gen2. It worked but I lost more than a third of the speed (links in Gen3 are 8gbps, versus 5 in Gen2). To solve the problem for good, edit /etc/default/grub Replace the line GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" with GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pcie_aspm=off" then run 'update-grub' However, it removes the PCIe power saving feature (for all connected devices, including the GPU), leading to useless power consumption, even more so on a laptop. there are other workarounds but they all shut up the logs. That's wrong as it can also hide more serious problems. The same 'pcie_aspm' setting also can be found for Windows, you can google it. Firmware is ECFM22.4 and I can't upgrade it as Silicon Power website does not recognize it's own capcha ! does not look good. Also, they have no utilities for Linux.

Overall Review: The performance is there, for a lot less than the leading brand. Not sure if the timeout problem is firmware related, and can't find out now as the vendor website is broken and won't let me see / download a newer firmware version.

Pros: Its my main drive with win10 pro. Boots up within 13 second with the BIOS being included. Game and files transfer at 2.8-3.1GBps on Read. Games don't load much quicker on a NVMe drive compared to a decent SSD but a second or two is a slight win.

Cons: None.

Overall Review: I will buy another for a new system. Having one drive vs a SSD + 1-4 HDDs/SSDs is a nice change.

Cons: Problems with thermal throttling and shut downs when gaming. Even when I moved my video card into the vertical position with a ribbon and off the top of the ssd, I still had problems. I ordered a heatsink for the nvme. Hopefully that helps.

Overall Review: Writes at around 3200. Reads are about 3400. Blows my 960 EVO away.

Pros: Price Performance Truth in advertising

Cons: Relatively unknown brand No documentation in packaging

Overall Review: Worked great. In Crystal disk mark it matched my Samsung 970 EVO (250GB) in sequential reads, and blew it away in every other category (better that a 25% performance increase, 50% in some cases), and with a 5 year warranty I'm very impressed for the price. Another thing that impressed me was that it beat its "up to" speeds in both sequential read and write scoring 3404 and 3054 respectively. The only downside is that there's no included guide or warranty statement in the box, but I feel like that's pretty nit-picky.

Pros: Quick, affordable

Cons: None in my experience

Overall Review: I didn't buy this expecting top of the line performance... However I'm extremely happy with it. If this lives its projected lifetime - this is a definite bargain. Setup in BIOS was pretty easy. It detected the drive immediately. All tests in BIOS cleared. Even CrystalDiskMark is putting the drives sequential read/write within less than 1% of advertised numbers. Who can argue with that?! Once I get the $ I plan to buy the 1TB model for the second M.2 slot.

Overall Review: I bought these based on my prior experience with SP products. "Taking a chance" a few years ago I purchased two SP 240gb SSDs. Both are still running great and are still competively fast, with transfer rates in the 500mb range. This purchase was for 2 and both are working properly and recognized correctly. I just finished the build. Windows 10 x64 boots in a few seconds.
