EN-Labs U2CR35MA 3.5" Internal Card Reader

The EN-Labs U2CR35MA is a 3.5" internal card reader designed for front-panel installation in a desktop PC bay. It connects via an internal USB 2.0 header and targets builders who need direct access to multiple legacy memory card formats without external dongles.

Metal case with six card slots and USB port hub

The unit fits a standard 3.5" bay and includes mounting screws for secure installation. Its metal chassis houses six slots covering CF, MS, MMC, SD, SmartMedia and xD formats alongside a high-speed USB 2.0 port hub. Active LED indicators show power and read/write activity for immediate visual feedback.

USB 2.0 interface limited to 480 Mbps transfer rate

The sole interface is USB 2.0, capping maximum throughput at 480 Mbps. This speed ceiling determines whether the reader suits your workflow; high-resolution RAW bursts or large video offloads will be bottlenecked compared to USB 3.0 or faster alternatives.

Questions about this item

Will the metal case or USB 2.0 header cable need replacement after years of daily card swaps?

The all-metal chassis and standard internal USB 2.0 header are built for long service; only the front-panel spring slots may loosen after very heavy use, and they are not user-serviceable.

What bottleneck appears first during sustained 480 Mbps transfers across multiple CF and SD cards?

The USB 2.0 interface caps sustained throughput at 480 Mbps, so the bus saturates before any individual card slot reaches its own speed limit.

How much heat and noise does the reader add when left powered all day in a 3.5" bay?

No fan or active cooling is present; the metal case stays near ambient temperature and produces zero audible noise during continuous operation.
