The SSD is read and written 1520465GB = 1.5PB, so it's a slightly fishy stuff, but the price is quite low as PCIe Gen4 2TB NVMe SSD. Its endurance is promoted as 1 DWPD which is equivalent to 3540 TBW for enterprise. This means its lifetime still remains more than half according to the spec though 1.5PB written. I thought the SSD would just fit to PS5 and got it. S.M.A.R.T. information and benchmarks show below as always. “Start Stop Count” and “Power On Hours” are too low for read/written bytes. I guess it may be leaked stuff for an endurance test. The remaining lifetime 88% per 1.5PB written means that the theoretical TBW gets 12.5PB. Benchmark results are on PCIe 3.0 environment. I haven't gotten any PCIe 4.0 machines yet.

It should bear cooling in mind. And now, as the point of interest to work with PS5, it doesn't… When power on my PS5 attaching PM9A3, screen is completely black and BD drive spins up and down repeatedly. It seems that it repeats to be reset and reboot while booting. I tried to attach another PCIe 3.0 SSD, then my PS5 showed the “Can't use the M.2 SSD inserted in the expansion slot.” screen up, so it is good. It tells me that PM9A3 can't work with PS5 for some reason somehow as of now. It's too bad. Hmmm, what should I treats the iffy SSD… Comments Name E-Mail Website Please fill all the letters into the box to prove you're human.
