Because of a combination between legacy BIOS and support only booting from a MBR (Master Boot Record) partition formatted drive, there are limitations when attempting to move to a higher capacity drive. With a drive sector size of 512 bytes, you arrive at the 2.19TB cap.

Windows and some Linux variants hit the 2.19TB capacity limit because they can only address 2 32 logical blocks (OSX is not affected by this limitation).

WD is banking on consumers working around this barrier, while we collectively wait for software and hardware to catch up, supporting larger drives natively.īefore we get too far along, it’s worth clarifying the 2.19 problem.

As it stands, one of the largest impediments to high-capacity internal drives is the 2.19TB barrier. Doing so gives consumers the option to have access to large capacity drives, but limits their utility by leaving them outside of the system. To this point, 3TB drives have been limited to external enclosures. We’ll dive into these potential compatibility issues and take a look a performance numbers in this review. While the high capacity is surely a blessing to many users, there are certain risks WD is taking by going to market right now. Other drive highlights include a 64MB buffer, 3Gb/s SATA interface and quoted standby power consumption of only 1W. In addition to the 3TB model (WD30EZRSDTL) there’s also a 2.5TB (WD25EZRSDTL) capacity available. WD accomplishes this feat by leveraging Advanced Format and four 750GB platters. Of course the major highlight this time around is the monster 3TB capacity, a first for internal 3.5" hard drives. Western Digital has both announced and started shipping their 5th generation Caviar Green hard drive.
