Sony MRW-E90 XQD 2.0 SD UHS-II Card Reader Review



The Sony XQD 2.0 SD UHS-II Card Reader (MRW-E90) reads both XQD and SD cards. It supports XQD 1.0 and 2.0 cards. SD support includes standard SD, SDHC and SDXC including UHS-I and UHS-II.The Sony reader case is made of grey plastic . The card slots are recessed on the of the reader, each with its own red LED access light. The lights are rather dim and can be difficult to see. The reader measures about 4 x 2 x 1/2 inch There is a USB 3.0 Micro-B port on the back of the reader and a short 20-inch USB 3.0 cable is included.

Both XQD and SD card slots provide a push-to-eject function. When a card is flush inserted it is nearly flush with the front of the reader. Pressing it will release it about 1/4 inch.


There are no feet or pads on the bottom of the reader so it will slide around on a surface. The reader tested is marked “Made in China.” The Sony MRW-E90 has a 1 year warranty. Supported operating systems include Windows 7 (SP1), Windows 8, 8.1 and Windows 10, as well as Mac OS X 10.8, 10.9, 10.10 and 10.11.

The Sony MRW-E90 provides very fast speeds for reading XQD cards. Write speeds were somewhat limited compared with the speeds measured in XQD devices. The highest read speed was with the updated Sony G-Series 440MB/s (read speed) card, which measured a 349.5 MB/s benchmark. UHS-II cards provided up to 249.7 MB/s sequential read speeds. While UHS-I cards provide read speeds up to 93.5MB/s, just slightly below those of the fastest SD card readers. Since it supports both XQD 2.0 and UHS-II SD cards, this reader is an excellent companion for cameras such as the Nikon D500 that use both card types.

Since the reader has no microSD slot, microSD cards were tested in an adapter, and UHS-II microSD cards were tested using a UHS-II SD to microSD adapter.
