Description
Add 4 RS-232 serial ports to your standard or small form factor computer through a PCI Express expansion slot
The PEX4S553 4-Port Native PCI Express RS232 Serial Adapter Card with 16550 UART lets you add 4 RS232 (DB9) serial ports, using a single PCI Express expansion slot.
Based on a native single-chip design, this 4-port serial adapter card allows you to 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 RS232 Serial Adapter Card includes 4 half-height/low-profile brackets, allowing the card to be installed into almost any PC case, regardless of form factor.
Backed by a StarTech.com Lifetime warranty and free lifetime technical support.
The StarTech.com Advantage
- Native single-chip, single lane PCI Express chipset delivers true PCIe performance, up to 48% more efficient than bridge chip designs
- Standard and low profile/half-height brackets included to ensure fitment in any system
Add 2 FireWire-800 and 1 FireWire-400 port through a Mini PCI Express slot

The MPEX1394B3 3-Port Mini PCI Express FireWire Card is a PCI Express to FireWire-800/FireWire-400 adapter that enables you to add external FireWire connectivity on very small form factor or embedded systems. The PCIe FireWire card provides two FireWire-800 ports and one FireWire-400 port, this adapter card supports the latest external FireWire storage devices at data transfer speeds of up to 800 Mbps. Using the Mini PCI Express (Mini Card) form factor, this adapter card is designed for use in the latest very small form factor computer systems, such as Mini-ITX or custom embedded solutions where a full-sized PCI Express card would not fit. Backed by a StarTech.com 2-year warranty and free lifetime technical support.

The StarTech.com Advantage
Add four USB 3.0 (USB 3.2 Gen 1) ports with four independent channels, LP/SATA power, and charging support to your PC through a PCI Express slot

The PEXUSB3S44V 4-Port PCI Express USB 3.2 Gen 1 Card lets you add four, dedicated 5 Gbps USB 3.2 Gen 1 ports to your PCIe x4-enabled PC. This independent port architecture improves USB 3.2 Gen 1 performance by transferring data on four individual channels to your computer, giving you faster file transfers.

When multiple devices are connected, traditional single bus USB 3.2 Gen 1 cards share your maximum bandwidth between all ports. By employing four host controller chipsets, each port operates on a separate independent transmission channel. Dedicating up to 5 Gbps to each USB port reduces performance bottlenecks, and effectively quadruples your total available to bandwidth to 20 Gbps.

Enhanced with UASP support (USB Attached SCSI Protocol), this USB 3.2 Gen 1 controller performs up to 70% faster than conventional USB 3.2 Gen 1 when paired with a UASP supported enclosure (Note: UASP requires a compatible operating system). Using a more efficient protocol than the traditional USB 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. See our UASP test results below for further details.

For high-power USB devices, this PCIe USB 3.2 Gen 1 card includes an optional SATA or LP4 power connector to connect to your system power supply and deliver up to 900mA of power per port to USB 3.2 Gen 1 bus-powered devices (500mA for USB 2.0). The USB 3.2 Gen 1 card also supports USB Battery Charging Specification 1.2 (Apple Mode only), letting you charge compatible Apple devices (iPhones and iPads) faster than a standard USB 3.2 Gen 1 port.

The controller card is compliant with USB 3.2 Gen 1 standards while offering backward compatibility with existing USB 2.0 / 1.1 devices. For added versatility, the USB 3.2 Gen 1 PCIe card is equipped with a standard profile bracket and includes a low-profile/half-height bracket for installation in small form-factor computers.

Backed by a StarTech.com 2-year warranty and free lifetime technical support.

Improved Performance with UASP

UASP is supported in Windows® 8, 8.1, Server 2012 and Linux kernel 2.6.37 or later. In testing UASP performed with up to a 70% faster read / 40% faster write speed over traditional USB 3.2 Gen 1 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, StarTech.com add-on USB 3.2 Gen 1 cards, a UASP-enabled StarTech.com enclosure, and a SATA III solid state drive.

The StarTech.com Advantage
This Mini-SAS adapter lets you convert two internal SFF-8643 ports on a controller card into two external SFF-8644 ports. This enables you to connect external SAS or SATA drives in devices such as a Direct Attached Storage (DAS) device to an internal backplane or SAS controller for additional storage.

The adapter can connect up to eight drives in total and is compatible with 12Gbps SAS drives as well as 6Gbps SATA drives. For a hassle-free installation, you can mount the adapter into any new or legacy desktop expansion slot, including: PCI, AGP, and PCIe. To ensure compatibility with most computer cases, full-profile and low-profile mounting brackets are included.

The SFF86448PLT2 is backed by a StarTech.com 2-year warranty and free lifetime technical support.
