AS SSD 1.7.4739 Results

AS SSD is a benchmark that uses non-compressible and completely random data. What this means is that the drives using controllers such as the SandForce SF-2281 cannot compress the data first, which takes away one of their strong advantages and help us score it more evenly against other drives.

On AS SSD’s Copy benchmark, we noticed that the ISO copy workload received the biggest boost as transfer speeds increased by around 50%. The Program and Game copy scenarios received more modest boosts to performance. And again, we saw notable increases in sequential read and write speeds. Performance increases on 4K reads were pretty modest, only around 30%; but 4K writes saw a whopping 400% increase. Finally, on the intensive 4K, 64-thread workloads, we recorded amazing improvements of around 230% and 1500% on read and write operations respectively.
