GRAID SupremeRAID SR-1010

The newer Gen4 card offers increased computation power and PCIe bandwidth. The PCIe bandwidth contributes to write performance since write data flows through the GPU card. This is where sequential write and random write performance double because of the bandwidth increase from 10GB/s to 20GB/s (PCIe Gen3 vs Gen4).

A more complete spec overview is below, and the detailed sheet from GRAID is here.

GRAID SupremeRAID SR-1010 Performance

To measure the performance of the SupremeRAID SR-1010, we leveraged our Dell PowerEdge R750 running Ubuntu 20.04 with eight Gen4 NVMe bays in front. We leveraged eight of the Memblaze PBlaze6 6926 12.8TB SSD, giving us a large footprint of high-performance NAND to use in a RAID5 configuration.

Since these are different SSDs than our last review, we completed a full round of new tests comparing RAID5 configurations using software RAID versus the SR-1000 and SR-1010. For Software RAID we leveraged mdadm with a 64K chunk size. Tests were performed running FIO against the RAID volume.
