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

Kingston's KC3000 does pretty well in the CrystalDiskMark 8 4K QD1 single thread test. Its read score of 83.49MB/s is the third-fastest we've seen to date for a consumer Gen4 drive but the write score of 251.49MB/s is not quite as impressive.

Comparing the benchmark result screens we can see that the Phison E18 controller that powers the Kingston KC3000 is much more efficient when reading compressible sequential and especially 4K random data at a queue depth of 1.

When it comes to the default Sequential test in CrystalDiskMark 8, the Kingston KC3000 has the fourth-best read figure (7,362MB/s) but its write result of 6,916MB/s is the fastest we've seen to date for a consumer Gen4 drive.

Switching over to the Peak Performance test profile we see the drive in second place in the results chart behind Patriot's Viper VP4300 drive with its read score of 7,384MB/s. When it comes to the 4K QD32 T16 test, the KC3000 sits in the top position with a read result of 668,752 IOPS with writes at 548,450 IOPS.

Kingston rate the Sequential performance of the KC3000 as up to 7,000MB/s for both reads and writes. The fastest read test result, 7,400MB/s, confirms the official figure while the best write figure of 6,919MB/s isn't that far short of the official maximum. The best 4K random figures we saw was when testing the drive with the Peak Performance profile, with the drive producing a peak of 668,752 IOPS with writes at 548,450 IOPS. However both of these a well short of the official 1,000,000 IOPS maximum figures for both.

Using the Real World default profile sees the KC3000 produce the best read result, 4,533MB/s, we've seen to date for a Gen4 drive in this test. Its write result of 5,862MB/s is the fourth-fastest we've seen behind Corsair's MP600 PRO (5,888MB/s), the 4TB version of Sabrent's Rocket 4 Plus drive (5,877MB/s) and MSI's Spatium M480 (5,864MB/s).
