Top reviews from the United States
There was a problem filtering reviews right now. Please try again later.
There is one throttling issue. In long random read testing the device will throttle to 76C, and the firmware throttles a bit too much. It drops from 1.4 GB/sec all the way down to 177 MB/sec for 10 seconds, then back to 1.4 GB/sec for 30 seconds, and repeats. I'm not docking them a star for this behavior for several reasons. First, they ship with a heat sink and most other M.2 devices do not. Second, it takes a while to hit this behavior. Third, they throttle at 77C which is nice and conservative, meaning less chance of early flash failures due to heat, and other M.2 devices (the Toshiba and the MyDigitalSSD) throttle at much higher temperatures. Plextor is giving its customers a gift by throttling at 77C, I can't dock them for it even though they could do with an adjustment. No need to throttle all the way down to 177MB/sec for short bursts :-).

SPECIAL NOTES ON THE PLEXTOR
* Consistent sequential write bandwidth (16GB, QD1) of 656 MB/s)
* Consistent random read results.
* Slow temperature ramp (good), no immediate throttling after stabilization at 77C
during read test (but it takes a while for it to get to 77C). Note that
the Plextor was the only NVMe device to ship with a heat sink, so this
is the expected result. However, it did start to throttle when I let the test
run significantly longer (see above). I don't consider it a show-stopper though.
* Nice chipset queue setup for a M.2 device (16/16 instead of
8/8 or 7/7).

Two things to note though:
1) The Plextor logo at post time adds about 3 or 4 seconds to your boot times when "Storage Boot Options Control" is set to Legacy. You can disable this but see below.
2) The only way to get this drive to show up to my Gigabyte Aorus Z270X Gaming 8 motherboard (bios F7beta) was under the BIOS tab to make sure that "Storage Boot Options Control" is set to "Legacy" (and NOT UEFI). That is the default option so the drive should be visible to the BIOS on a fresh build. You need to keep this option set in order for the windows8/10 installer to see the drive (no extra drivers were needed for me during the install though). Once windows was loaded I switched that setting back to UEFI for fast posting. It works great!
NOTE: the Aorus Z270x BIOS will still not show anything in "Peripherals" --> "NVMe Configuration" section but as long as you can see the Plextor M8Pe as the primary boot target (in the "BIOS" tab) and you see the Plextor splash screen each time when you post you are fine for a windows8/10 install.
I have other brand M.2 NVMe SSD drives and they all run HOT!!! when in extended use, the heat sink on this drive makes a big difference in keeping this drive "cooler".

I would recommend it to anyone looking for a SSD, its just a little more expensive than a SATA SSD
