WD Blue 320 GB Mobile Hard Drive: 2.5 Inch, 5400 RPM, SATA II, 8 MB Cache - WD3200BPVTJust wanted to chime in with my experience: if, like me, you have felt frustrated with the storage capacity of your PS3 drive, but aren't sure you are capable of upgrading it yourself: don't be intimidated by the process. Even a middle-aged woman Gamer like me can ace it. Couldn't be easier.
Took me a while to write review as I had to wait for it to be installed. Old hard drive went bad so I needed a new one. This one was very reasonable with more space. Hard drive arrived in great timing. Details about item explained well. Fit perfect. Just what I needed.
My hard drive crashed on my Toshiba laptop, and I replaced it with this WD drive.Installation went smoothly, and my laptop is running great! The only reason I didn't give it 5 stars is because I've noticed a noise at times that I didn't have previously. It's not bad, but it is different.Overall, I'm very pleased so far. I've had it for about a month....only time will tell how long it will last.
It works fine and is according to specifications.Western Digital has never been my favorite brand, but the Blue series seem to have less failures. As a 5400 RPM SATA II drive it is good. The seller send the drive immediately and it was very well packaged, so we added them to the favorite list.
I never got a chance to use the drive. Windows couldn't see it. ...Another SATA drive I have, 1TB , also Western Digital, is seen by Windows, so it's not the Operating System. ...Too bad..! ...I'm beginning to wonder about Western Digital quality control. ... No wonder they're lowering the warranty time of these drives, from the usual 3 years, to now only 2 years. ... Such a shame. ...
I purchased this hard drives with the intention on upgrading my slim 4GB model Xbox 360. The hard drive fit into the Xbox 360's SATA port without case and it is working perfectly. If anybody wants more space for your Xbox 360 Slim 4GB this is the best choice, the WD Blue 320GB HDD.
Did a lot of searching before settling on this excellent product. Price was right on target. Connection and installation was a snap. Highly recommend the Scorpio series of drives.Western Digital 320 GB Scorpio Blue SATA 3 Gb/s 5400 RPM 8 MB Cache Bulk/OEM Notebook Hard Drive - WD3200BPVT
Salvaged this hard drive -- well, a similar model under the same name with the intent of using it externally. It works beautifully, runs quietly, barely even noticed it with a SATA to USB 3 (superspeed) adapter. It requires no extra power than that from a USB port, so it can be used just like a flash drive.As a portable storage solution, make no mistake, this works.
got hard drive; installed & loaded windows. worked great for about 2 weeks & went to cut it on; blue screen of death? no operating system found.... tried formatting & reloading; nothing worked. dead drive?? sent it back to the company for replacement; hope the new one works better/longer...  unusual for western digital; usually a great product! !
Answer: Just transfer speeds.  They are backwards compatible.
