I wouldn't go with a Crucial drive unless you're getting the 128GB or bigger. The smaller drives take noticeable performance hits compared to their bigger brethren. The notorious C300 speeds are only achieved by the larger drives. The smaller ones are in the ballpark, but they're not up to the SF drives at those sizes.
If you're looking for reliability above all, go Intel.
If you're looking for performance below 128GB go SF.
If you're looking for performance at or above 128GB and you don't have SATA3 flip a coin between SF and Crucial.
If you're looking for performance at or above 128GB and you have SATA3 go Crucial.
However, The C300 is week in two areas. 4k random writes, and capacity. You have to admit that being able to fill the SF drives to capacity without taking a performance hit is a real advantage. The JMicron controller of the C300 doesn't do any compression, so the only spare aria available is the default 7 percent.
A few corrections here, Fish:
- The C300 drives are using a Marvell controller, not JMicron.
- The SF drives *do* take a performance hit if you fill them up, look at Anand's graphs in his articles.
- The ability of the SF controller to use free space beyond the over-allocated amount has nothing to do with compression. The Intel controller also uses all available free space just like the SF controller does.
