Summary: I bought this to repair a laptop that belonged to a co-workers son. It was compatible for the Compaq laptop. Installed easily and I had the laptop back up and running in no time. (well with the exception of the hours of Windows Updates that had to be installed) It was far cheaper to buy this thru amazon then to purchase from local stores, definitely cheaper than direct from Compaq. The HD operates quick and quietly. No issues with it so far.
Summary: This has been a quiet and reliable hard drive for the last 8-10 months. Absolutely NO evidence of the noise, vibration or unreliability that some of the reviewers warn of. Must be due to their laptop's characteristics or the few bad 'apples' that every manufacturer (WD included) produces.
Summary: I was hesitated to buy this drive but there have been a lot of positive feedback at Newegg lately. Thus I gave myself a try, especially with the recent cheap price + free shipping. I should have paid attention to all the negative reviews here at Amazon. Noisy: Bought it 2 weeks ago; installed it on Aug 19, 2010 to replace my 40GB Seagate Momentus 5400 RPM on one of my laptops. The drive is noisy to me; perhap I use it in my quiet home office, no TV, no one but myself.
Summary: In all honesty I was looking for a larger Hard Drive to replace my internal laptop drive but since the 1TB 2.5" only comes in 12.5mm thickness and most laptops only fit 9.5mm thickness this was the next best option. I'd recommend this to anyone that can take advantage of the security features. My laptop has the option of using boot passwords which locks your drive until you enter your password even before the Operating System starts.
Summary: Excellent seller. Hard drives came very fast. Although, I asked to return the HD's because after I ordered them I asked the seller about the warranty. The seller responded that they are OEM which was easy to over look. It was stated OEM in the Amazon search results that list different companies for this specific Hard drive (which I noticed after the sellers response) but it was not stated when I clicked on the actual item or store to buy it.
Summary: Uppgraderade min Macbook Pro med denna 7200-varvare från en 160 GB 5400. Skillnaden är: Större utrymme, brummar mer, drar mer batteri men upplever en marginellt kortare söktid. Uppgraderade även RAM samtidigt. Passar mig som prioriterar prestanda framför batteritid. Bra med 5 års garanti.
