The Crucial m4 (Micron C400) SSD Reviewby Anand Lal Shimpi on March 31, 2011 3:16 AM EST
AnandTech Storage Bench 2011—Light Workload
Our new light workload actually has more write operations than read operations. The split is as follows: 372,630 reads and 459,709 writes. The relatively close read/write ratio does better mimic a typical light workload (although even lighter workloads would be far more read centric).
The I/O breakdown is similar to the heavy workload at small IOs, however you'll notice that there are far fewer large IO transfers:

Despite the reduction in large IOs, over 60% of all operations are perfectly sequential. Average queue depth is a lighter 2.2029 IOs.
Our light workload actually does a lot better on the m4. The m4 is virtually tied with Intel's SSD 510 as the second fastest drive we've tested thus far over a 6Gbps interface:
Over a 3Gbps interface the m4 is actually no faster than the old C300.
