Performance
The performance has been tested on the AMD Ryzen platform that contains the Ryzen 9 7950X, 16-core processor, ASUS Crosshair X670E Gene motherboard, ADATA Lancer Mera Edition 32GB DDR5-7200@6200 memory kit, and Acer Predator GM7000 2TB M.2 SSD with installed Win11 Pro x64. All tests were performed on the Crucial T700 2TB SSD.
Let’s begin as usual with the ATTO Disk Benchmark.
Results in ATTO benchmarks are always slightly lower than expected, so we are glad to see 11.47GB/s maximum read and 11.06GB/s maximum write. Either way, it’s the highest bandwidth on a single SSD we have seen in our redaction.
In CrystalDiskMark is about the same story. A bit lower maximum bandwidth than expected, but it’s still exceptional for a single SSD. What is for sure impressive is the IOPS result with over 1600k! It’s more than specified by Crucial.
In PCMark 10, the results are also surprisingly good. The Data Drive Benchmark shows one more, the highest result we have seen, with up to 1205MB/s, which is about 30% faster than the second SSD we have tested.
A similar performance gain can see in 3DMark Storage Benchmark, which shows about a 20% higher score than the second-best result.
Anvil’s Storage Utilities is a rather old benchmark but is still popular. This benchmark usually shows lower results than the ATTO or the CrystalDiskMark. It doesn’t change the fact that the results are pretty high.
In the end, the AIDA64 Disk Benchmark results in random read and write operations.
These extended tests show some thermal throttling. Especially write test has some performance drops. On the other hand, even with these random performance drops, these results are about as high as that of top PCIe 4.0 SSD. Better cooling should improve already high bandwidth.
Thermal throttling wasn’t visible in other long tests, like PCMark Storage tests or 3DMark Storage Benchmark. The high temperature explains why most brands decided to use small fans on their PCIe 5.0 SSD. It’s still not required for gaming which causes additional noise. The T700 has no fan, but it’s asking for better cooling. Even though the heatsink keeps the SSD at acceptable temperatures during typical load or gaming, then long work would require a good airflow or an additional fan next to the SSD. I feel like the better idea would be to use a motherboard heatsink. Large M.2 heatsinks are available on high-end motherboards, but also only high series have M.2 PCIe 5.0 sockets.
