TeraStation 3 TB SATA drive

This Buffalo OP-HD3.0T/4K-3Y is a 3 TB internal hard drive built for 3.5-inch bays. It connects through a SATA 3.0Gb/s interface and uses 4K sector formatting. The drive is qualified for Buffalo TeraStation ES, III, III iSCSI, Pro and Pro WSS arrays.

For RAID replacements in listed arrays

It suits administrators who need a direct replacement or capacity upgrade inside a compatible TeraStation. Buyers who want a standalone desktop drive for a non-TeraStation system should look at something else, as the firmware is tuned for array use.

SATA 3.0Gb/s interface

The drive communicates over a SATA 300 connection with a maximum external transfer rate of 384 MB/s. This single interface specification determines whether the drive will install and operate in the target enclosure.

商品問答

Does this drive need a SATA 3.0Gb/s port on the motherboard or RAID controller to work?

Yes, it connects through a standard 7-pin SATA interface running at 3.0Gb/s, so the host must provide a matching SATA port.

Can I mix this 3 TB drive with smaller drives already in my TeraStation RAID array?

The drive will appear at the size of the smallest drive in the array, so it can replace a failed smaller unit but will not add extra usable capacity.

How can I verify the drive is transferring at its rated 384 MB/s after installation?

Run a sequential read benchmark such as CrystalDiskMark or HD Tune; a healthy drive on a 3 Gbit/s link should show sustained speeds near 384 MB/s.
