Benchmarks: As SSD Benchmark

The fastest drive in the As SSD Benchmark's sequential read test was the new Samsung 840 120GB which reached 504.5MB/s. The Crucial m4 64GB wasn't a great bargain slower hitting 502MB/due south, while the 128GB version sustained 492.7MB/s. The older Samsung SSD 830 64GB besides managed a transfer speed of 494.9MB/s making it 1 of the fastest drives tested.

Further down the graph nosotros find the Kingston HyperX 3K 90GB which managed a respectable 444.3MB/s, making it faster than the 417MB/s of the OCZ Vertex 4 128GB. The slowest of the agglomeration was the Kingston SSDNow V+200 120GB which achieved a throughput of 198.2MB/s due to its utilize of asynchronous NAND flash.

Once more we find that the write functioning is what separates these drives. When compared to their larger capacity siblings these smaller SSDs endure when it comes to write functioning.

The OCZ Vertex 4 128GB is the fastest SSD on this exam nonetheless information technology's withal 12% slower than its 256GB equivalent. Nevertheless the performance hit seen when going from 256GB to 128GB is nada compared to the delta between the 128GB and 64GB drives, a staggering 51% reduction in performance.

It was a similar example when looking at the Crucial m4 range. The 128GB model was merely 13% slower than the larger 256GB drive, notwithstanding the 64GB version was a whopping 43% slower than the 128GB model.

And yet, when it came to sequential write performance the Vertex 4 was a clear winner with the 64GB model beating the larger capacity drives from Kingston, Crucial and Samsung.

Jumping to the Equally SSD Benchmark 4K-64 thread performance, the OCZ Vertex 4 128GB keeps sitting pretty.

The Crucial m4 series (64GB, 128GB and 256GB models) all performed within 10MB/s of one another. The only SSDs to endure in this exam were the Kingston SSDNow 5+200 120GB and Kingston HyperX 3K 90GB every bit they delivered just 90.4MB/s and 114.9MB/south.

The OCZ Vertex 4 128GB and 64GB smoothen again on this test while the Crucial m4 128GB came in tertiary spot with 156.9MB/s, followed past the Kingston SSDNow V+200 120GB with 138.9MB/south. The Samsung SSDs struggled, with the new Samsung SSD 840 120GB delivering just 101.5MB/due south while the old SSD 830 64GB was capable of a mere 46.6MB/s.

As you can see the read admission times are very similar with no more than 0.090ms separating the fastest SSD from the slowest.

At that place is a considerably larger difference when comparison the write access times. The Crucial m4 serial stands out here, unfortunately for being quite tiresome. In comparison the OCZ Vertex 4 and Samsung SSD 840/830 drives were much faster.
