WD Desktop Mainstream WDBH2D5000ENC-NRSN 500GB 7200 RPM 32MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive

Pros: Title says it all. 120gb for the OS and this drive for Mass storage. Best bang for the buck. I'm not surprised that its "IntelliPower" because this drive is designed to be eco friendly and quiet

Cons: No cons so far after using it for 4 months. A minor con is that this is just a bare drive. No screws nor SATA cable. But motherboards these days have lots of SATA cables anyways but just know this is just the Drive alone. Asides from the instructions of course.

Overall Review: If your building a computer. This would be a good drive to pair this with a SSD of your choice. I have been using WD drives fir 2 years now ranging from their laptop drives to desktop. So I know WD will be having my business for future storage needs.

Pros: Western Digital has a good reputation for reliability.

Cons: Incomplete specifications - what is the spin speed? If they don't tell you it often means the default speed is 5900 rpm, not the faster, more responsive 7200 rpm.

Warranty is only 2 years.

Overall Review: We're looking to maybe add another 2TB drive to our system. We like WD but this seems kinda slow and kinda pricey compared to, say, the Toshiba 2TB which clearly has faster 7200 rpm speed, costs less and has a 3-year warranty .... (newegg Item#: N82E16822149397 )
