Summary: bought 6 on 2 occasions. one failed after two months tried to access rma for 1 of the 6 drives. apparently you need the ean or the s/n on the "PACKAGING" and not on the drive and since i no longer have the packaging i dont think i can get rma for the drive. you would think they put one of the numbers "on" the drive itself. it appears running these on a ich10r controller will only net me close to 700MB/s read and write and not even close to what i'm supposed to get.
