CrystalDiskMark is a useful benchmark to measure the theoretical performance levels of hard drives and SSDs. We are using v8.0.5.
In CrystalDiskMark 8's 4K QD1 T1 test, the Crucial T705 with Heatsink takes over the top spot from the T700 heatsink version but only just, but enough to be the fastest drive we've seen to date in this test.
As you can see from the benchmark default result screen we can confirm the official Sequential read/write figures of 14,500MB/s and 12,700MB/s respectively with test result figures of 14,506.47MB/s for reads and 12,739.40MB/s for writes.
Those Sequential scores are the fastest we've seen to date for a consumer NVMe SSD. The T705 is some 2,101MB/s faster than the previous T700 for reads and 913MB/s faster when it comes to writes.
Peak Performance Profile.
Looking at the Peak Performance benchmark result screens we could confirm the official 4K random read figure of 1,550,000 IOPS with a default test result of 1,575,736 IOPS. When it comes to random writes, the test result of 1,654,925 IOPS was somewhat off the official maximum of 1,800,000 IOPS.
Using the Peak Performance profile of the CrystalDiskMark benchmark we could once again confirm the official Sequential performance figures.
Once again those Peak Performance profile Sequential figures are strong enough to put the drive in the top spot on the results chart.
Real World Profile.
In the Real World Profile Sequential test, the T705 sits just behind the T700 when it comes to reads but the T705 has a much stronger write performance, 10,925MB/s compared to 10,008MB/s.
