AS SSD 1.7.4739 results

AS SSD is a benchmark that uses non-compressible and completely random data. This removes the advantage of controllers who compress data first before manipulating them, such as the old SandForce SF-2281 controller. Therefore, this is a useful benchmark in creating a level playing field for all controller types.

The Intel SSD 730 Series continued to disappoint on AS SSD. Its recorded speeds for the Copy benchmark was the lowest of the drives. The SanDisk Extreme Pro fared much better and was one of the top performing drives. However, it still found itself trailing against the Samsung SSD 850 Pro. The fastest drive in the Copy Benchmark was the recently reviewed Samsung SSD 850 Evo.

Moving on, we can see that Intel’s decision to use 128Gbit NAND has severely hampered write performance. Sequential write speeds were only just above 280MB/s, whereas drives like the SanDisk Extreme Pro and Samsung SSD 850 Pro were managing close to 500MB/s. Fortunately, read speeds were still decent, but only just. The SanDisk Extreme Pro was a much better performer, but again, it was outperformed by the Samsung SSD 850 Pro.
