Turn a 2.5\" SATA Hard Drive or Solid State Drive into a UASP supported USB 3.0 External Hard Drive. The S2510BMU33 USB 3.0 Hard Drive Enclosure with UASP lets you connect a 2.5in SATA III hard drive (HDD) or solid state drive (SSD) 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 2.5\" 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 1TB) this HDD enclosure is compatible with virtually any 2.5in SATA hard drive, and greatly increase the storage/backup capabilities of your computer. The USB 3.0/SATA III enclosure requires no external power adapter and features high quality aluminum construction, ensuring both portability and durability when carried as a laptop accessory.
