Turn a 3.5" SATA HDD into an external upright UASP-supported Hard Drive with built-in fan. The S3510BMU33B 3.5in SATA hard drive enclosure lets you add external storage to your computer by connecting a 3.5" HDD through an available USB (Universal Serial Bus) 3.0 port. Enhanced with UASP (USB Attached SCSI Protocol), this enclosure lets you get the most out of your SATA III hard drive with performance up to 70% faster than conventional USB (Universal Serial Bus) 3.0 when paired with a UASP-enabled host controller. The enclosure features aluminum housing with a built-in fan to keep your drive running at an optimal temperature at all times. Plus, to help save valuable work space, the enclosure features an upright design that minimizes its footprint & makes it easy to position near your computer. With support for SATA I/II/III, & large capacity drives (tested up to 4TB) this HDD enclosure is compatible with virtually any 3.5in SATA hard drive, & can greatly increase the storage/backup capabilities of your computer. UASP is supported in Windows 8, Mac OSX (10.8 or above), & Linux. In testing, UASP performs with a 70% faster read speed & 40% faster write speed over traditional USB (Universal Serial Bus) 3.0 at peak performance. At the same peak in testing UASP also shows an 80% reduction in required processor resources. Testing results were obtained using an Intel Ivy Bridge system, a UASP-enabled Star Tech.com Enclosure, & a SATA III solid state drive.
