CrystalDiskMark is a useful benchmark to measure the theoretical performance levels of hard drives and SSDs. We are using v8.0.
Under CrystalDiskMark 8's 4K QD1 test the 1TB Seagate FireCuda 520N read score of 78.65MB/s sees the drive in the top ten of 1TB class drives tested. Its write score of 230.85MB/s is pretty average for a 1TB Gen 4 drive.
Looking at the CrystalDiskMark benchmark result screens we can confirm the official Sequential performance figures of up to 4,800MB/s for reads and up to 4,700MB/s for writes with a read test result of 4,842MB/s with writes at 4,901MB/s. Switching over to compressible data (0 fill) saw the read result rocket up to 7,325MB/s while the writes dropped to 3,217MB/s
The FireCuda 520N Sequential read test result of 4,842MB/s sees the drive in the bottom half of the results table.
Peak Performance Profile.
Using the Peak Performance testing profile in CrystalDiskMark 8 we saw the best test results for 4K performance of 741,537 IOPS for reads and 580,731 IOPS. Both these figures are well short of the official maximums of up to 800,000 IOPS for reads and up to 900,000 IOPS for writes. Although the test results are nowhere near the official maximums, the FireCuda 520N is the fastest Gen4 drive we've seen to date for this test.
Real World Profile.
Using the default Real World profile of CrystalDiskMark 8, we saw Sequential figures of 2,990MB/s for reads and 4,825MB/s for reads and writes respectively. Switching over to the compressed data option (0 fill) sees the read performance rise to 5,766MB/s while the writes drop to 3,055MB/s.
