Using CrystalDiskMark we see that the both sizes of the M100 offered enough sequential read speed to max out the SATA 6Gb/s bus so they are as fast as any other high-speed SATA device that we have tested.
The MX100 512GB was again able to max out the SATA 6Gb/s bus when measuring sequential write performance, though the 256GB version on the other hand was limited to just 346MB/s, quite a bit slower than the OCZ Agility 4.
The random 512K read performance of the MX100 512GB and 256GB was impressive, reaching almost 440MB/s, placing them among the quickest of their kind.
The MX100 512GB had strong random 512K write performance with 459MB/s, just 35MB/s slower than the fastest SATA SSD test, while the MX100 256GB model was considerably slower sustaining only 346MB/s, landing it between the Plextor M6M and Intel SSD 335.
The random 4K-QD32 read performance was average, though the MX100 series was still able to match the Plextor M6S, SanDisk Extreme II and Samsung SSD 840 Pro.
The random 4K-QD32 write performance was surprisingly strong as both the MX100 256GB and 512GB models sustained roughly 320MB/s, faster than almost everything tested except the OCZ Vertex 460/450 and Vector 150.
