Built a new system with ssd.
Put 2.5 inch 750gb wd7500kbpt for storage.
When I run atto benchmark i get 60+mbps.
I just tried transferring files, for less than 1mbps, and when I put my lightroom catalouge on there it was unusable.
make sure the ssd on the intel or amd 6g sata ports. check that the sata ports are set to achi mode. download and install the newest mb chipset drivers. if an intel mb download istore. make sure the ssd firmware is up to date.
