PRODUCT OVERVIEW

<b>Connected with the Future</b><br><br>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.<br><br>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).<br><br>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.<br><br>This enclosure comes in two variants:<br>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 Federal Logistics Information System (FLIS) under NSN 3110-00-156-7549, indicating validated use in U.S. government and defense logistics supply chains.
