ADATA Premier Pro SDXC UHS-1 U3 Card Review (128GB)

Higher quality media requires greater data rates to capture it. This means that storage requirements call for greater speed and capacity. The newest DSLRs are able to take high speed continuous bursts at 20 megapixels+ per image, resulting in 20-50MB per RAW image taken. To record 4K video, cameras typically eat up around 20-30MB/s per second minimum! With data rates like these, storage manufacturers have to release products that meet these requirements.

ADATA Premier Pro 128GB Angled

To answer these needs, today we have one of ADATA’s solutions on the review table, the 128GB Premier Pro SDXC card.

The packaging is very similar to the previous ADATA XPG we recently reviewed. A typical plastic clamp shell and cardboard packaging with all the specs listed on the front and back. Also, on the back is a small chart listing the approximate amount of media it can hold, from 11400 24MP images to 160 hours of 4K video. And a QR code and link to ADATA’s website where you can register for your lifetime warranty and free software.

At 128GB in capacity, this card is currently the largest SDXC card they offer. However, if 128GB is too much for you, they have a 64GB version as well rated at the same speeds. MSRP for the 128GB is $109.99 and $59.99 for the 64GB. When formatted the 128GB card is of 117GB usable capacity. It is rated as a UHS-I U3 card, thus minimum sustained speeds are 30MB/s. Advertised speeds are 95MB/s read and 60MB/s write, which should be plenty fast for almost anyone in the market for a SDXC for their high resolution cameras.

The card shell is a standard blue and of standard dimensions with a mechanical write protection switch. The front has a sleek black sticker with rated capacity and speeds. On the back are the surface contacts and a generic number code which matches that of the ADATA XPG we’ve previously reviewed.
