Western Digital 1TB SATA GREENPOWER Bulk/OEM Hard Drive WD10EACS

As hard drive capacities increase, the power required to run those drives increases as well. WD Caviar GP makes it possible for energy-conscious customers to build systems with higher capacities and the right balance of system performance, ensured reliability, and energy conservation.

Can't beat a Western Digital product over the competition, at least in my opinion and experience with two other brands. For just over $100 I got a fast 1tb hard drive that installed in a snap. I plan to get many years use out of this one.

There is an even better version of this drive out, Western Digital WD10EADS 1TB SATA 32MB Cache Green Power Bulk/OEM Hard Drive. Look for that version instead - it has better speed, and lower power consumption. Tom's Hardware says "We have to advise against getting the first generation Caviar Green drive--the WD10EACS--because the current model WD10EADS is just so much better. ... If you want an efficient drive go for the WD Caviar Green WD10EADS, not the WD10EACS."

I purchased this hard drive to use as an upgrade in my TiVo HD. It replaced the stock 160gb drive, which was capable of holding only 20 hrs of HD video. This drive allows me to now store 160 hrs of HD video and almost 1500 hours of SD video. Awesome upgrade for my TiVo HD. Note - This drive WILL NOT work in the Series 3 TiVo as an upgrade as it is the WD10EACS-00ZJB0 which causes the Series 3 to get stuck in an endless boot cycle.

This is my biggest stress reliever because this drive does what technology is supposed to do - JUST WORK! Guys I am almost 60 and I now have 3 of these drives that I use in my Drobo - the best back-up tool I have ever used for my Mac/VMWare Windows desktop and laptop. This works great for my small business. The drives make no noise and my Drobo is always cool to the touch. I don't have to do anything. These drives are simply plug and work. They just automatically back up both my laptop and desktop (unfortunately the Drobo wireless accessory does not work with Macs yet so I have to plug in the firewire cable into my laptop when I want to back it up but that's all I do). I live overseas and despite my trembling fingers on the first drive I installed into the Drobo - these drives push in like a VCR tape and you've got instant back up and oodles of memory. It sure beats the drives I was continuously buying every few months and wondering what to do because I couldn't afford the RAID and other servers. With the Drobo and Time Machine backup is idiot proof - this basically has your info on two drives in case one drive fails. When I had another drive and it failed within days after the warranty expired, I called the manufacturer and the tech guy said - "You need to reformat your drive. So where's your back up?" - I said "this was my bloody back up." No more pain with these affordable and reliable drives and my Drobo. We have already recovered info because of a mistake syncing data that ended up getting overwritten. I thank the guys at the Apple Store in MD for telling me what to buy and Amazon for having them at a reasonable price.

This is my favorite STORAGE drive. It runs quiet and cool and it is relatively inexpensive. I have bought several, with the first one being for my TiVoHD and it's been working great for almost a year now. However, I would not use this drive as a main drive for someone who wants great performance. NOTE: Newer models of this drive use 3 platters instead of 4 and are faster and even more efficient. These drives run at 5400 RPM.
