Looking for best 2tb internal drive and dock

I am getting ready to buy four 2tb internal hard drives and a couple of docking stations to upgrade my HD media players (PopCorn Hour C-200 & Dune player) 2.0 & 3.0 2tb external usb hard drives. Are these any good? Looking for reliability and fast HD movie transfer speed. Have any recommendations on a good dock and internal hard drive? What is the difference between green and black WD drives? What is the difference between 64MB Cache & 32MB Cache?

hi ,just adding my 2 cents , the first drive is only 5400rpm so it would be slow ,2nd drive has bad reviews for failure on the link you provided ,the dock i actually have one of those and it works good for data transfer ,that is all i have ever used it for ,its only usb connected so speed would be a factor ,you should connect harddrive to you computer via sata port for best speed .

difference between 64meg and 32 meg cache is 32meg more space for OS to save data to for faster access by your operating system .

difference between green and black drive is green is environmentally friendly ,how that affects the drive I'm not positive ,power consumption is biggest difference i think .

the drives you show are cheap and as always ,you get what you pay for .i have 2 western digital 320 gig drives myself,but just for OS and some storage ,and one is used with the doc for backing up data on customers computer that im fixing .

Green drives are environmentally friendly, so they might be a tad slower than black drives. They run around 5400rpm (http://techreport.com/articles.x/15769) and have lower power consumption. You can read the review to see how it fares versus typical 7200rpm drives.

The cache (32MB vs 64MB) is the memory of the hard drive for quick access, allowing for higher performance. You can read this for more detailed explanation, although it's a bit outdated. Cheap drives these days use 16MB, and I guess the standard is 32MB for good performance.
