Add 4 external USB (Universal Serial Bus) 3.0 ports to a low profile or standard computer, through PCI Express. The PEXUSB3S4V PCI Express USB (Universal Serial Bus) 3.0 Card (with SATA Power) adds 4 external USB (Universal Serial Bus) 3.0 ports to any PCI Express-enabled computer system with support for data rates up to 5 Gbps, while remaining backward compatible with USB (Universal Serial Bus) 2.0 / 1.x devices. Enhanced with UASP support (USB Attached SCSI Protocol), this USB (Universal Serial Bus) 3.0 controller performs up to 70% faster than conventional USB (Universal Serial Bus) 3.0 when paired with a UASP supported enclosure (Note: UASP requires a compatible operating system). Using a more efficient protocol than the traditional USB (Universal Serial Bus) BOT (Bulk-Only Transport), UASP technology optimizes transfers by allowing multiple commands to be processed simultaneously, significantly increasing transfer speeds for less wait time on data transfers. The card uses a "stacked" port layout that places the ports one on top of the other, enabling all four USB (Universal Serial Bus) 3.0 ports to be external facing, while still allowing the card to fit into a small form factor/low profile computer system using the included low profile bracket. Plus, with a built-in SATA power connector, each USB (Universal Serial Bus) port can provide up to 900m A of power to devices that draw power from a host bus connection (500m A for USB (Universal Serial Bus) 2.0) by connecting to your computer power supply. UASP is supported in Windows 8, Server 2012 & Linux kernel 2.6.3 or later. In testing UASP performed with up to a 70% faster read / 40% faster write speed over traditional USB (Universal Serial Bus) 3.0 at peak performance. At the same peak in testing, UASP also showed up to an 80% reduction in required processor resources. Test results were obtained using an Intel Ivy Bridge system, Star Tech.com add-on USB (Universal Serial Bus) 3.0 cards, a UASP-enabled Star Tech.com enclosure, & a SATA III solid state drive. ...

The PCISATA4R1 4 Port PCI SATA RAID Controller lets you add four internal SATA 1.0 (1.5 Gbps) ports to your PC through a single PCI expansion slot, while offering support for several RAID modes or a simple JBOD (Just a Bunch of Disks) configuration. The PCI SATA card provides increased performance & capacity with RAID 0 (Striping), or a redundant copy of your hard drive with RAID 1 (Mirroring). Configuring in RAID 10 (a.k.a. RAID 0+1) lets you leverage both by creating a mirrored copy of your striped disk set. Plus, the SATA RAID card supports RAID 1+S (Mirror + Spare), which uses a third installed drive to automatically replace a failed drive & rebuild the mirrored set
- even if it is the boot drive that failed. For the ability to fit most standard computer cases, the card ships with a standard profile bracket installed &

Includes:: a low profile bracket for adapting to slimline or small form factor systems. While the PCISATA4R1 card supports any size hard drive in JBOD mode, the max supported drive size when in RAID mode is 2 TB (per port).
