Turn a 3.5\" SATA Hard Drive into a UASP-supported USB 3.0 External Hard Drive. The S3510BMU33 Black USB 3.0 Hard Drive Enclosure with UASP lets you connect a 3.5in SATA III hard drive (HDD) through an available USB port. The enclosure delivers optimal performance with a USB 3.0 connection, but is backward compatible with USB 2.0/1.1 host connections as well. Enhanced with UASP (USB Attached SCSI Protocol), this 3.5\" SATA III enclosure performs up to 70% faster than conventional USB 3.0 when paired with a UASP-enabled host controller. Using a more efficient protocol than the traditional USB BOT (Bulk-Only Transport), UASP reduces latency, significantly increasing transfer speeds and reducing processor usage to utilize the full potential of your SATA III hard drives. With support for SATA I/II/III, and large capacity drives (tested up to 4TB) this HDD enclosure is compatible with virtually any 3.5in SATA hard drive, and can greatly increase the storage/backup capabilities of your computer. The USB 3.0/SATA III enclosure features high quality aluminum construction, ensuring durability.
