Specifications, Pricing and Availability
The Crucial M500 ships in four capacity sizes. The smaller drives are not as fast as the two larger models, but this is to be expected after testing a handful of 20nm flash SSDs.
All four M500 models have a sequential read speed of 500MB/s. The write speed scales with capacity - 128GB writes at 130MB/s, 240GB writes 250MB/s and the two largest sizes are speced at 400MB/s. IOPS performance scales as well as you can see in the chart above. The 960GB size that we're looking at today tops 80K read and write 4K IOPS.
The M500 comes with a three year warranty, but it has a stipulation. There is a 72TB cap for the warranty. That comes out to 40GB written to the drive everyday for five years so it's not like Crucial is handcuffing you to an unreasonable cap, still we would prefer a solid warranty without a limit.
Crucial isn't the first to limit the amount of data written to the drive for warranty purposes, OCZ did it with Vector and Samsung's new 840 Series has a cap as well.
