Speed values in CrystalDiskMark

First Poster

Hi all,

I would like to buy a Samsung 970 EVO Plus 1TB SSD, and then measure its read and write speeds mentioned in the specifications:

Sequential read/write: Up to 3,500/3,300 MB/s

Random read/write (4KB, QD32): Up to 600,000/550,000 IOPS

Random read/write (4KB, QD1): Up to 19,000/60,000 IOPS


Which settings should I use in CrystalDiskMark to have the closest results to your ATTO measurements?

Sequential read/write = Seq Q32T1?

Random read/write (4KB, QD32) = 4KiB Q32T1?

Random read/write (4KB, QD1) = 4KiB Q1T1?



And which test size should I use (50MiB to 32GiB)?

Thank you,
