this seems low, my 950pro (256GB) does: Timing cached reads: 21216 MB in 1.99 seconds = 10660.10 MB/sec Timing buffered disk reads: 5444 MB in 3.00 seconds = 1813.68 MB/sec (On an Asus Sabertooth X99 mainboard, X99 chipset with i7-5820K CPU) I though the 256GB was supposed to be slower than the 512GB version. Not the other way round. -- Joost
