I have Windows installed on SSDs. I have gone through many Samsung SSDs that all experience the same problem: 250 MB/s max for both Read and Write -- I think this is SATA 2 at fault here. What really concerns me though, is the IOPS. Random Read only gets about 8,000 IOPS Random Write only gets about 25,000 IOPS. Is this also due to SATA 2? The results are from the Samsung Magician software.
