Pros: Cheap

Cons: I ordered 4. 1 was DOA, the other 3 will not accept more than 4GB of data. They came formatted FAT32, reformatted to NTFS and still no joy. Transfer speeds are less than 10MB/s, not USB 3.0 speeds. Product packing has item identified as USB 3.1, not even close even with the new USB spec name changes.

Overall Review: I should've read the reviews before purchasing. Will I recommend - NO Will I purchase again - NO

Pros: -Decent price -Worked great and was fast...

Cons: -Will not recognize as NVMe -POST logo annoying with no way to config -Very slow after install

Overall Review: I have been working with PC's since they were "Workstation Consoles". I imaged this drive from an existing working system (older Intel NVMe), swapped the M.2 SSD's, and booted. First start was impressive. Cold post to idle in less than 20 seconds with a complete OS, drivers, and apps (Win10 x64, multiple gaming and development VM's, internal RAID 10, dual 10Gb NAS 40TB RAID). It should be noted that the only thing that actually loads from the SSD is the OS, everything else comes from both RAID. My orginal SSD cold post to idle is more than double that. After the initial boot the Plextor post to idle is north of 90 seconds, most of which comes from the very slow POST due to the unconfigurable logo and that the MB will no longer recognize it as an NVMe drive. My original M.2 has no problems being recognized as NVMe and still logs ~40 sec POST to idle times. Just for giggles I tried the Plextor in both AMD and Intel rigs and got the same results, different MB makes too, same results. I'm thinkin' the common denominator might be the Plextor. I'm not gonna say don't buy this, I just wouldn't buy another one. New product lines have bugs, most get handled and fixed properly by the producing companies. I'm just going to invest elsewhere. For those concerned about drivers... Drivers only work when you can get into the OS. They don't help when the problem is at the BIOS/UEFI level. That requires a microcode patch, I haven't seen one of those for a storage device since the mid 90's.
