Summary: I purchased this to replace a 300 that was my boot drive. Arrive in only a few days; I cloned my boot drive using Acronis, opened up my computer, slid the old one out and inserted this one and now have double my space! Worked like a charm. Good price, great shipping; it doesn't get any better.
Summary: I like WD black hard drives. This Velociraptor 600 has been just a good. I have used it for several year now and it is still working. I have a SSD on the front end and this as a secondary. Works very well.
Summary: I bought 2 of these back in October of 2011 and they never really seemed to have the performance they were supposed to. Well one finally failed and when I contacted Western Digital, I was told they are not real WD drive but a counterfeit. I sure hope Amazon stands behind their products..
Summary: Like many others, I have been severely disappointed in this drive (Velociraptor 600 GB SATA III 32 MB Cache). Specifically: 1) High performance is attained only with certain controllers. This is very unlike other SATA III hard disk drives. Most hard drives perform about the same regardless of controller. In some systems the Velociraptor is very fast; meaning noticeably better than a 7200 RPM hard drive (but never close to an SSD).
Summary: Have wanted one of these since they came out. Fastest HD outside an SSD. What a nice difference in performance. HD related tasks cut in half. WD reliability and lightning speed. What else can you ask for?
Summary: You can't get a better drive than this, unless you go SSD. Great price for this drive. Was way more a few months ago. want to get fast speeds, get a SSD for windows and use this drive for data. You just can't go wrong.
