Large Capacity Drives

Meeting the technological challenges of 3 TB SATA hard drive implementation.

Once again leading the way in the storage industry, WD now offers 2.5 TB and 3 TB hard drives, the world's largest capacities to date on a single drive. At such high capacities certain compatibility issues arise. There are a number of host bus adapter (HBA) and chipset vendors not currently offering drivers that support drives larger than 2.19 TB. To provide a solution for these types of compatibility issues, WD is bundling WD Caviar® Green™ 2.5 TB and 3 TB drives with an ACHI-compliant HBA that, once installed, allows the operating system to use a known driver to correctly support large capacity drives.

To understand if your system will support a hard drive with greater than 2.19 TB, consult your OS, Motherboard and USB bridge device solution providers from the list below before you attempt to install in your system.

USB bridge devices

USB attached storage solution providers have solved many of the issues associated with Large Drives within the USB Bridge firmware. Some present large capacity drives as single drive using larger sector sizes while others present the large capacity drive as more than one or more smaller drives to the host. Please consult the solution provider for their solution availability and implementation details.
