The sequential read performance of the Samsung 830 Series 512GB is outstanding with a throughput of 513MB/s. This kind of performance puts the 830 Series 512GB on par with the very best SandForce SF-2200 drives. When compared to the OCZ Vertex 3 240GB the 830 Series 512GB was 4% faster while it crushed the Crucial m4 256GB by a 28% margin.

If the sequential read performance of the Samsung 830 Series 512GB was outstanding then we are going to need a more colorful way to describe the sequential write performance. Perhaps I will leave that to the reader as it is hard to put the throughput of 404.6MB/s into words. This meant that the 830 Series 512GB was 34% faster than the OCZ Vertex 3 240GB and roughly 57% faster than the Crucial m4 256GB and Samsung 470 Series 256GB drives.

The random 512K read performance is considerably lower though a throughput of 335MB/s is nothing to be scoffed at. Here the Samsung 830 Series 512GB delivered similar performance to that of the Crucial m4 256GB and Intel SSD 510 Series 120GB drives, though it was 5% faster. However when compared to the OCZ Vertex 3 240GB the 830 Series 512GB was 23% slower.

The random 512K write performance was also quite average and this time the Samsung 830 Series 512GB was only able to deliver roughly the same performance as the 470 Series 256GB with 252.7MB/s. This meant that it was 5% slower than the Crucial m4 256GB and 15% slower than the OCZ Vertex 3 240GB.

Although the random 512K performance was average the Samsung 830 Series 512GB makes a quick recovery in the random 4K-QD32 test with a throughput of 275.3MB/s. This meant that it was just 6% slower than the OCZ Vertex 3 240GB while it was 66% faster than the Crucial m4 256GB.

The random 4K-QD32 write performance was not quite as impressive and although the Samsung 830 Series 512GB was 94% faster than the 470 Series 256GB it was only able to match the Patriot Pyro 120GB. This meant that the 830 Series 512GB was 35% slower than the Crucial m4 256GB and 42% slower than the OCZ Vertex 3 240GB.
