When Western Digital launched the WD10JPVT, a 1 TB Scorpio Blue drive, it featured two of their new high-capacity 500 GB 2.5" platters. The drive was thus able to fit standard 2.5" storage bays. If you recall, the original 1 TB Scorpio Blue drive (the WD10TPVT) had a thickness of 12.5 mm, which prevented it from fitting most 2.5" storage bays, thereby relegating it mostly to special applications like portable USB drives. Even so, the standard 9.5 mm form factor of the WD10JPVT was too thick for the Ultrabooks. To accommodate these thinner notebooks, Western Digital created the WD10SPCX, which is basically an improved 7 mm version of the WD10JPVT. It sports two of the same 500 GB Advanced Format platters in a slimmer form factor, with double the SDRAM cache and a faster SATA 6 Gb/s interface. But will all that translate into better performance? Let's take a look. Link : Western Digital Blue (WD10SPCX) 1 TB Slim Mobile Hard Disk Drive Review
