Benchmarks: File Copy Test
The single large compressed file is a game ISO weighing 6GB and Crucial's MX100 512GB managed just 223MB/s, which is comparable to the recently reviewed Plextor M6S 256GB and Crucial m4 256GB. This means the MX100 is about 100MB/s slower than the fastest 2.5" SATA SSDs we've tested, such as the Samsung SSD 840 Pro, SanDisk Extreme II and OCZ Vertex 450.
The MX100 256GB was 23MB/s slower than the 512GB version, putting it on par with the Samsung SSD 840 Evo 1TB.
The program copy test is comprised of many small non-compressed files (6104 files totaling 2.75GB). The MX100 512GB performed much better here with 188MB/s, not far off the pace of the fastest 2.5” SATA SSDs that we have tested. The MX100 256GB was 18MB/s slower than the 512GB model which did seat it towards the bottom of our graph, though having said that it is still amongst some pretty high class competition.
The game copy evaluation is a mixture of small and large, compressed and non-compressed files. Again the Crucial MX100 512GB did quite well with 236MB/s, just 41MB/s slower than the fastest SATA SSD we've tested. The MX100 256GB was 39MB/s slower than the 512GB model and that was enough to place it just above the Intel SSD 520 Series, the fourth slowest SSD.
