CrystalDiskMark is a useful benchmark to measure the theoretical performance levels of hard drives and SSDs. We are using v8.0.

In the CrystalDiskMark 4K QD1 T1 test, the Blue SN580 does pretty well, with a 82.4MB/s read score with writes at 226.64MB/s, good enough to see it in sixth place in the results chart. It's also an improvement on the previous generation SN570 which scored 68.45MB/s and 200.67MB/s (read/writes respectively) for the same test.

Looking at the two benchmark screens, it's clear that the in-house WD controller doesn't really have a preference for the type of data it's being asked to handle. We could also confirm the official Sequential performance figures for the drive; up to 4150MB/s for both reads and writes with test scores of 4,171MB/s for reads and 4,172MB/s for writes.

Those Sequential scores see the drive in last but one place on our results chart.

CrystalDiskMark 8 Peak Performance profile.

 

CrystalDiskMark 8's Peak Performance profile result screen displays the 4K result in IOPS. The best-read test result of 618,479 IOPS confirms and betters a little the official rating of up to 600,000 IOPS. However, the tested write result of 701,165 IOPS is someway short of the official 750,000 IOPS.

Although the 4K read score of 618,291 IOPS is only good enough to see the drive in the bottom half of the results chart, its write score of 701,165 IOPS is the second fastest we've seen to date for a 1TB class Gen 4 drive.

The read and write results of 4,171MB/s and 4,172MB/s respectively in CrystalDiskMark 8's Peak Performance profile confirm the official ratings of 4,150MB/s for both reads and writes.

CrystalDiskMark 8 Real World profile.

 

The Real World profile Sequential read/write results of 3,909MB/s and 4,160MB/s respectively show the improvement in performance that the Gen 4 interface, which the Blue SN580 uses, offers over the Gen 3 interface of the previous generation SN570. The SN580 read result is 1,195.20MB/s faster than the older drive while the write result is a 1,242.87MB/s improvement.
