PRODUCT OVERVIEW

20312: ADAPTER,QUICK DISCONNECT,SEAT.

Connected with the Future The USB 3.0 port of this external enclosure for 2.5'' SATA HDDs makes superfast data transfer possible. That's because USB 3.0 has a tenfold bandwidth compared to USB 2.0 and even a good advantage against SATA. The ICY BOX IB-250StU3-B/-BH accomplishes the superfast data-transfer rates in connection with a host and a cable which are USB 3.0 compatible too.

If the host PC is not equipped with a USB 3.0 controller our adapters for the PCI slot or the express-card slot are fine alternatives (ICY BOX IB-AC604 or IB-AC605). As USB 3.0 is downwards compatible the ICY BOX IB-250StU3-B/-BH cooperates also with conventional USB 2.0 devices providing the USB 2.0 bandwidth. Thus this ICY BOX can be the first stepping stone into the faster USB 3.0 future.

This enclosure comes in two variants: IB-250StU3-B is for 2.5" SATA HDDs with 9.5 mm height, and IB-250StU3-BH is for those with 12.5 mm. This part is cataloged in the U.S. Government catalog under NSN 3110-00-156-7549, indicating validated use in U.S.

government and defense logistics supply chains.
