Benchmarks: AS SSD Benchmark
The sequential read performance when testing with the AS SSD Benchmark is identical to the results recorded with CrystalDiskMark. The Kingston SNV425-S2 64GB and ADATA S596 Turbo 32GB drives well out in the lead followed by the Intel X25-V 40GB. The OCZ Agility 2 and Vertex 2 40GB provided a throughput of 143-145MB/s making them slightly faster than the OCZ Onyx 32/64GB SSDs which produced a bandwidth of 126-127MB/s.
The AS SSD Benchmark shows slightly different performance trends when looking at the sequential write performance, though for the most part things remain much the same. The Kingston SNV425-S2 64GB is still the fastest SSD tested though this time it is outgunned along with all the other SSDs by the Samsung Spinpoint F1 1TB. The Seagate Momentus XT 500GB also matched the performance of the OCZ Agility 2 and Vertex 2 40GB SSDs which was impressive.
As we found when testing with CrystalDiskMark, the OCZ Onyx 32/64GB SSDs matched the ADATA S596 Turbo 32GB with a throughput of 55-60MB/s. Finally the Intel X25-V 40GB was the slowest drive tested providing just 41MB/s.
The AS SSD Benchmark 4K queue depth 64 test provided similar results to that of the CrystalDiskMark 4K-QD32 test. The read results are almost identical and again we see that the Intel X25-V 40GB dominates this test.
The AS SSD Benchmark 4K-64 Thread results are almost identical to those from the CrystalDiskMark 4K-QD32 test. The OCZ Agility 2 and Vertex 2 40GB SSDs are superior performers in this test while the Intel X25-V 40GB also displayed strong performance.
The AS SSD Benchmark includes an access time test and first we are going to look at the read performance. Here the Intel X25-V 40GB provided the quickest access time and was closely followed by the OCZ Agility 2 and Vertex 2 40GB SSDs. The OCZ Onyx 32/64GB SSDs also provided quick access times while the ADATA S596 Turbo 32GB and Kingston SNV425-S2 64GB drives were noticeably slower.
The Seagate Momentus XT 500GB and Samsung Spinpoint F1 1TB drives are truly slow in this test.
The access times when measuring write performance provided similar performance trends and the ADATA S596 Turbo 32GB was the only drive that improved its position. The access times of the hard drives improved quite a bit though the Seagate Momentus XT 500GB still fell behind the Samsung Spinpoint F1 1TB.
