Sequential Read Performance
With the exception of Crucial’s m4, all of the drives we're including top out between 530 and 550 MB/s in sequential reads. That's the practical limit of what we can expect from SATA 6Gb/s, so don't expect to break past that barrier any time soon.
Dipping back to a queue depth of one is where we see the biggest differences between drives, though. Samsung’s 840 Pro serves us close to 410 MB/s, and the Vertex 4 isn't far behind. In comparison, the SSD 335 (like other SandForce-based SSDs) starts out around 310 MB/s and only manages to beat that m4 drive.
Sequential Write Performance
Examples include Application Installation, Document Backup
In many ways, the graph of sequential write performance looks a lot like the chart for sequential reads. At a queue depth of one, the SSD 330, 335, and 520 all deliver about 350 MB/s and eventually top out around 510 MB/s.
Although Monster’s 240 GB Daytona eventually hits the same ceiling, it starts a bit lower and doesn't scale up as quickly. Meanwhile, Samsung's 840 Pro tops the chart again.
