WD's Terabyte Scorpio Notebook Drive Tested
MojoKid writes "Recently, Western Digital stepped out and announced their new 1TB 9.5mm Scorpio Blue 2.5-inch notebook drive. The announcement was significant in that it's the first drive of this capacity to squeeze that many bits into an industry standard 9.5mm, 2.5" SATA form-factor. To do this, WD drove areal density per platter in their 2.5" platform to 500GB. The Scorpio Blue 1TB drive spins at only 5400RPM but its performance is actually surprising. Since areal density per platter has increased significantly, the drive actually bests some 7200RPM drives."
It depends somewhat on your workload:
Being at the top of the areal density pile will make your nice, long, continuous reads or writes run like a bat out of hell; but it isn't nearly as useful if you are dealing with highly scattered reads and/or writes. If the area you need has passed the head, you just need to wait until it comes around again.
Long run, high-RPM drives are probably on their way out, since high-density, lower-RPM ones do impressive linear performance and absurdly low cost, while decent solid state gear kicks out the I/OPs better than an entire shelf of 15k screamers; but you can certainly construct tests, not entirely artificial, where RPM matters more than density, within reason.
"These drives have actually been on the market for well over a year now, and I was (un)lucky enough to pick one up last year when my local Fry's Electronics got them in stock."
The 9.5mm, 1TB version? Over a YEAR? Even Samsung's 9.5mm 1TB drive only came out a few weeks back... it only came into regular stock last week. WD's version isn't even showing up in online shops yet.
WTF are you talking about?
