Western Digital has both announced and started shipping their 5th generation Caviar Green hard drive. Of course the major highlight this time around is the monster 3TB capacity, a first for internal 3.5" hard drives. WD accomplishes this feat by leveraging Advanced Format and four 750GB platters.

Huge 3TB capacity; Speed increases over the 2TB model; Lower write; idle; and startup power consumption; As bleeding edge as it gets for computer storage for now

Compatibility will be an issue for some until systems meet UEFI standards; Significantly higher price per GB over 2TB model

Verdict: A top-notch drive that boasts superlative performance and an enormous amount of storage capacity.

That's a big chunk of change for 50% more capacity. You could purchase two 2TB drives for less than the price of a single 3TB unit. However, keep in mind that you'd also end up with twice the power consumption and twice the heat generation, so it might not be a good trade-off for small form factor...

W estern Digital's WD 30EZRS certainly looks an attractive storage solution with an enormous 3 TB capacity and a 64 MB cache. The new 3TB internal hard drive for desktops looks like a good option for those who want to store a ton of movies, software, games and images.

The Western Digital Caviar Green 3TB drive overcomes a boundary that has taken hard drive manufacturers quite some time to overcome, but it falls short of wowing us. The overall performance of the drive is extremely lacking and we found that even as a backup drive, it lacked the speed that it's...

Two months ago I looked at the world's first 3TB desktop hard drive . It was a 5 platter, 3TB Seagate Barracuda XT inside an external GoFlex Desk chassis. The performance of the drive wasn't anything out of the ordinary, but the poorly ventilated chassis seemed ill equipped to deal with the thermal...

Western Digital just upped the capacity ante with a mind-blowing two-terabye internal hard drive. It doesn't break any land speed records, but the 2TB Caviar Green is unmatched for capacity-at least for now.

Highest-capacity consumer drive on the market; Low power consumption.

Not particularly fast; the extra 500GB costs more than $100

Western Digital is one of the big names in hard drives, and one of their latest releases puts a much stronger emphasis on the word big. Model number WD20EADS is a 3.5" SATA 3Gbps hard drive from their "eco-friendly" Caviar Green series that sports 32MB of cache memory and an industry leading 2TB of...

» Largest capacity drive currently available; » Big doesn't mean slow; » Energy efficient; » Runs cool and quiet

» High price tag; » Lots of data to be lost with one drive failure

The Western Digital Caviar Green line of SATA HDDs ranging from 500GB to 2TB capacities. Western Digital Caviar Green 2TB Hard Drive is designed to be fast but the prime focus is on power conservation and capacity.

Rules were made to be broken; that whole 55 MPH thing happens to be my favorite. Western Digital had larger aspirations; the kinds that considered milestones. Reaching the 750GB per platter mark is definitely in the milestone category and that is what Western Digital is releasing today.
