Testing The First PCIe Gen 5.0 NVMe SSD On Linux Has Been Disappointing
When looking at the sequential read performance with FIO and using IO_uring, the TD510 at Gen5 speeds was reading at 9,462 MB/s compared to the 10,000 MB/s rating by the manufacturer. Even when running at Gen4 speeds, the TD510 was offering read speeds better than the likes of the Samsung 980 PRO, WD_BLACK SN850, and Solidigm P44 Pro.
The sequential write performance with FIO and using IO_uring was even faster with a 9613 MB/s adverage for the Inland TD510 at Gen5 speeds (though when at Gen4 speeds was much slower than the other comparison candidates). The 9613 MB/s writes comes out slightly ahead of the 9,500 MB/s Inland rating.
While the sequential read and write performance was looking great, the random read and write performance with FIO IO_uring was disappointing. Random reads were just slightly faster than a WD_BLACK SN850 while random writes were slower than the tested PCIe Gen4 SSDs.
When moving to other I/O workloads besides just synthetic storage benchmarks, the Inland TD510 on Linux also continued to disappoint.
