The 256GB Crucial M550 is a welcome improvement over the 240GB M500. The new Marvel 88SS9189 controller has addressed our primary concern with the M500 which was poor sequential write speed. With sequential read/write speeds of 510/478 MB/s the M550 has a healthy core performance profile. Comparing the M550 and M500 shows that the new M550 leads on nearly every single performance metric. Unfortunately the M550 is priced significantly higher than the M500 but prices will likely drop as retailers build up stocks of the new M550. A key comparable for the M550 is the similarly priced market leading Samsung Evo. Comparing the Evo and M550 shows that the Evo is around 11% slower in terms of effective speed[Mar '14 SSDrivePro]

My rating was for the M550 512Gb SSD because Crucial Website says (AFTER I ordered one from Amazon) that it is not compatible with an ASUS Sabertooth Z87 motherboard. I mean. Why in F**K would a very recent SSD not be compatible with a very recent high-end motherboard? What nutter markets SSD`s which are (otherwise) secretly not going to work on modern PC`s ???

I have one M550 / 256GB, one M500 / 240GB and old M4 /128GB. M550 is very good, very fast SSD.
