The UHS-1 spec is characterized by a significant performance boost defined by the SD Association as possessing "bus-interface speeds up to 312 Megabytes per second for greater device performance in SDXC and SDHC host products." So far, the new interface has proven to have a substantial impact in applications where streaming full HD & 3D video and rapid fire JPEG & RAW still photography is imperative. This means it is quickly being adopted by burst mode nature, wedding, and even portrait shooters concerned with never missing a shot. Additional Elite 633 features include advanced Error Correction Code (ECC), reliable Wear Leveling, and storage integrity in harsh environments (including static, vibration, shock & UV light exposure). The Elite633 memory card also provides seamless integration into any SDHC, SDXC or Class 2, 4, 6 & 10 host device and is backed by Delkin?s trusted lifetime warranty.

Best memory card for mirrorless cameras by Parka at Daisuki Photo, 01-13-2012
(For full review, please visit: http://daisukiphoto.com/content/best-memory-card-mirrorless-cameras)
My tests are not lab tests. I just use a stopwatch to record the time it takes to write a file. Several results are taken and then averaged out.
I'll be comparing only the best and fastest SDHC memory cards currently available for mirrorless cameras. Currently, the fastest (marketed) are the 95MB/s UHS-1 cards from SanDisk and Delkin Elite. I'll also compare it with a Transcend Class 10 as a baseline.
The cameras I'm using are the Fujifilm X100 and Panasonic GH2. X100 needs the fastest possible card to compensate for its slow performance. GH2 because that's the camera I have that can write the highest resolution photo at 16MP.
For GH2, RAW files are around 17.5MB and JPEG at 3.3MB in size. For X100, RAW files are around 19MB, and JPEG at 4.2MB. Yes, X100 files are bigger even though the photos of 12MP. Surprising.
