Simplecom SE221 Aluminium 2.5″ SATA HDD/SSD to USB 3.1 Enclosure

The Simplecom SE221 turns any 2.5″ SATA hard drive or solid-state drive into a premium external USB storage device. Encased in anodized aluminium, it offers professional aesthetics, robust protection, and efficient thermal management. Whether you’re archiving critical data, editing large media files, or carrying multimedia libraries on the go, the SE221 delivers dependable performance in a compact footprint.

Design and Build Quality

The SE221’s unibody aluminium chassis not only resists scratches and minor impacts but also acts as a passive heatsink. Its anodized finish repels fingerprints and corrosion, maintaining a refined look over time. At just 122 × 78 × 14 mm and 75 g, the enclosure slips neatly into laptop bags or pockets without adding bulk. A slim LED indicator on the front edge provides clear power and activity feedback without disrupting the enclosure’s minimalist styling.

Connectivity and Performance

Next-generation USB Type-C technology is at the heart of the SE221. Its reversible port supports USB 3.1 Gen 1 transfer rates up to 5 Gbps, enabling large-file moves—such as 4K video or virtual machine images—in seconds rather than minutes. The enclosure includes both a USB-C to USB-C cable and a USB-C to USB-A adapter, ensuring compatibility with modern ultrabooks, tablets, desktops, and even legacy USB 2.0 ports (at reduced speeds).

Inside, the SATA III 6 Gb/s interface is paired with UASP (USB Attached SCSI Protocol) acceleration. UASP reduces command overhead, cutting latency and boosting sustained transfer performance—especially when used with high-speed SSDs. In head-to-head benchmarks, drives in the SE221 often outperform standard USB-to-SATA adapters by up to 30%.

Installation and Compatibility

You’ll appreciate the SE221’s tool-free, screwless design. To install a drive, simply slide open the aluminium housing, align your 7 mm or 9.5 mm 2.5″ SATA HDD/SSD with the internal connector, and snap it shut. No screwdriver or extra parts required, making drive swaps a breeze. Bus-powered over USB, the enclosure requires no external adapter or power brick.

The SE221 is natively supported on:

• Windows 7 and later
• macOS 10.4 and later
• Most Linux distributions (plug-and-play, no drivers needed)
