Optane 905P and PM1725B SSD
I would like to purchase Optane 905P 960GB and Samsung PM1725B 6.4TB for research purposes.
Each price is around 180 million won for 905p, and pm1725b is about 2.6 million won.
1TB SSD The price of optane is really ignorant considering that it is also in the vicinity of 100,000 won.
Each appearance is roughly like below. (The photo shows Permalink here)
Each specification is as follows.
For reference, the Optane 905P uses the same x4 band as the M.2 SSD, but the PM1725b has a maximum performance of around 6300mb / s using the x8 band, but it is a little lower on the actual bench.
Bench results are shown below. 905P / PM1725b.
Deep queue / seq performance is good for PM1725b, but also Optane has 4k read performance.
Especially in atto, since 32kb, it is impressive that the performance is the same as the knife.
I do not know why, but PM1725b is selected, so there is a delay of 10 seconds when booting from uefi stage at boot time. It does not seem to be a problem.
