Vertex LE vs Crucial C300

[GullLars]

onex, disregard that AS SSD screenshot from legit-reviews. It's done using IDE mode, and says so in the picture. This is evident in the 4K-64Thrd numbers, wich don't scale. In AHCI or RAID mode, an x25-M G2 160GB can do 140-160MB/s read at 4K-64Thrd, and up to 80MB/s write, typical around 60MB/s. Sequential write should also be around 100MB/s, not 80.

In reply to point 4 you listed above, we (me, and anvil) have already researched this, and found write-through give a significant IOPS boost (through lower latency overhead), while resulting in lower max bandwidth.
EDIT: graphs
EDIT2: to clarify the graphs. The SSDs are Intel x25-M G1, G2, and x25-V. The number of SSDs are listed first, then M/V, then G1/G2, then capacity, then write-back (WB) or write-through (WT), and lastly IOmeter file size.
The Y-axis is bandwidth in MB/s, and the X-axis is Queue Depth.
EDIT3: The controller used here is Anvils LSI 9260-8i. Firmware from january-february i think. So i think that makes the second firmware released.
EDIT4: I have all the graphs in much higher resolution, and the xlsx document with all the raw data, if anybody wants the excel file, i'll post it.
