CrystalDiskMark is a useful benchmark to measure the theoretical performance levels of hard drives and SSDs. We are using v8.0.
In CrystalDiskMark 8's 4K QD1 T1 test, the Crucial T700 Heatsink sits on top of the results chart thanks to its read performance which is slightly faster than the other two Gen 5 drives and the two fastest Gen 4 drives, Lexar's Professional NM800 PRO and WD's Black SN850X.
As you can see from the benchmark result screens we can confirm the official Sequential read/write figures of 12,400MB/s and 11,800MB/s respectively with test result figures of 12,405MB/s for reads and 11,826MB/s for writes.
Those Sequential scores are the fastest we've seen to date for a consumer NVMe SSD and they give a hint of what's to come from Gen 5 drives in the coming months as the full data transfer speeds are unlocked.
Using the Peak Performance profile of the CrystalDiskMark benchmark we could once again confirm the official Sequential performance figures.
Looking at the benchmark screens we could confirm the official 4K random read/write figures of up to 1,500,000 IOPS for both with a read test result of 1,555,964 IOPS with writes even faster at 1,653,175 IOPS.
Crucial's T700 Heatsink sits just under the standard T700 in the Real World Profile chart with Sequential read/write scores of 9,392MB/s and 10,008MB/s.
