Add 4 high-speed RS-232 serial ports to your PC through a low profile PCI Express expansion slot. The PEX4S952LP 4 Port Low Profile Native RS232 PCI Express Serial Card (16950 UART) turns a PCI Express slot into four RS232 (DB9) serial connections. The card is constructed using a native single chip design that lets you harness the full capability offered by PCI Express (PCIe), while reducing the load applied to the CPU by as much as 48% over conventional bridge chip serial cards. The PCI Express RS232 Serial Adapter Card is compatible with a broad range of operating systems, including Windows 2000/XP/2003/ Vista, Linux Kernel 2.6.11 & up, & ships with a half-height/low profile bracket installed, but also

Includes:: an optional full profile bracket that lets you add four serial ports to virtually any computer (regardless of the case form factor).

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. ...
