Crucial M4 128GB SSD Review
The write speed barely takes any time at all to run at full chat. Even with only 8kb chunks it's already racing along at 160 MB/s. Read speeds naturally need a bit larger cluster size before it can push the 300 MB/s barrier, but either way the M4 is a speedy little thing.
In case you're wondering what the real world benefit of having a faster drive entails, here is a real-world example. Encoding a video file in x264 format on a i7-970 is considerably faster with the M4 handling the temporary storage during the encode than the identical test run on the relatively quick Kingston V+. The difference between 3Gpb/s and 6Gpb/s in a nutshell.
