Buffalo OP-HD4.0T/4K-3Y hard disk drive

4TB 4K Sector Optional Hard Drive for TeraStation If the capacity is not available, a larger capacity drive can be used to replace a TeraStation hard drive. For example, if replacing a 500 GB hard drive in a TeraStation, customers can use a 1 TB model. Hard drive capacities and availability change from time to time, so in some cases a larger hard drive must be used as a replacement. If a larger hard drive is used in a RAID configuration, it will appear as the same size as the other hard drives in the array.

For TeraStation Pro WSS customers, please select replacement hard drives with the same physical sector as what is currently installed in your unit.
