Comes in a branded box.

The reader itself is packed into a plastic blister. The set includes a warranty card and a manual.

The device has a metal case with UGREEN engraving.

On the side there are slots for microSD and SD memory cards. It is declared their simultaneous operation.

Features:

• Memory cards: SD / microSD up to 512GB
• Max speed: 5Gbps
• Chipset: GL3224
• Material: Zinc alloy
• Dimensions: 57.4 * 17.6 * 9.5 mm

Cards in the connectors do not chatter, fixed well.

We are going to test using SanDisk Extreme PRO V30 32GB memory card. The card was specifically purchased for the DVR and has good read/write speeds.

For comparison I inserted the memory card directly into the mini PC. Built-in card reader interface is only USB 2.0, speeds are appropriate.

Test of simultaneous operation of two cards. Used SanDisk Extreme PRO V30 and slow Eaget hc1 via adapter.

Process of copying files from SSD to two cards simultaneously. When using two cards the speeds are severely cut. You don’t really notice it with Eaget, because write speeds are about 20mb/sec in normal mode, but with SanDisk it’s very noticeable.

After all the tests the card reader was slightly warm.

Conclusions

A card reader with the size of a normal USB flash drive and the ability to simultaneously work with two memory cards. When writing to 2 cards at the same time, the speed is severely reduced. With a single card such problems were not noticed, the card reader works 100% and provides maximum speed. The metal case provides good heat dissipation.
