Turn a 3.5in SATA drive into an external USB 3.0 hard drive. The SAT3510U3V USB 3.0 to SATA external hard drive enclosure allows almost any standard 3.5-inch internal SATA Hard Disk Drive (HDD) to be made into a cost-effective external SuperSpeed USB 3.0 hard drive. With data transfer rates up to 5Gbps (10 times faster than USB 2.0), speed is no longer compromised for convenience, ease of use or portability. Large capacity drives (tested with up to 4TB) can be used to greatly enhance your computer''s storage/backup capabilities. The USB 3.0 HDD Enclosure is backward compatible with USB 2.0, making it more than suitable for use with computers that don''t yet have USB 3.0 ports. The external enclosure will also power down SATA drives after a period of inactivity (USB mode only) or when the PC is turned off, to help reduce power consumption and noise when not being accessed.
