Thunderbolt 2

The fastest, most versatile I/O in any desktop. Of any size.

Thunderbolt 2 technology in ST4-TB is phenomenally fast. The two Thunderbolt 2 ports on ST4-TB features dual 20-Gbps channels for data transfer and that’s up to four times faster than USB 3. But beyond speed, Thunderbolt gives you unprecedented expansion capabilities. You can daisy-chain as many as six Thunderbolt devices to a single port. And since Thunderbolt is based on Display Port technology, Mini Display Port devices like Apple LED Cinema Display can plugs right in, too.

The ST4-TB is equipped with four configuration modes to suit every need

The ST4-TB has four built-in disk configuration modes: RAID 1 (Safe Mode), RAID 0 (Speed Mode), RAID 10，JBOD (Two Independent Volumes) for you to choose according to your needs.

The RAID 1 function provides fully automatic backup that ensures data security.

RAID 0 functionality increases storage speed and performance.

RAID 10 is a RAID configuration that combines disk mirroring and disk striping to protect data.

JBOD function provides two independent disk data access convenience.

RAID 0 functionality increases storage speed and performance

The new ST4-TB is equipped with RAID 0 storage mode, which enables user to attain up to 724MB/s read speed with ST4-TB's Thunderbolt transmission interface. Whether it is used for searching and editing photo galleries, or video editing and synthesis, it promises to deliver a smooth and easy operation.

Stylish and rugged

The ST4-TB has a sleek exterior design that’ll never go out of style when placed next to your Mac. It’s also built tough with three millimeter thickness aluminum to shield the enclosed drives durably and to dissipate the heat created by the drives faster for the drives to work comfortably.
