    • Fast card for sequential burst photos in RAW.
Capacity: 128gb Style: V90 Ultra
As usual the OWC product seems to be working great, and arrived very quickly. This is my first SD card from OWC but I’ve purchased other storage/memory devices from them. All have worked well, arrived on time, and have been great quality. Unfortunately the memory market is way out of control right now on price, but this card was at a great price for a V90 rated card compared to others. I’m using this in a Nikon D850. Although I have plenty of cards for this camera, none of my others are rated as V90. They are fine for the landscapes and other images like that but doing fast action sequences I fill the buffer quickly. This card allows for standard 7FPS sequences with RAW images without buffering issues until you have done a lot of images in a row. When shooting hockey or birds in flight I was hitting buffers. I don’t shoot video, so can’t comment on that. I also am only using el-en15 batteries, so I can only comment on 7FPS. I have not used the card heavy yet, but early testing it seems to be doing what I’m looking for. ... show more

    • Fast, quality SD cards for my newest Camera.
Capacity: 128gb Style: V90 Ultra
Got these to replace my aging Sony Tough SD cards for our upcoming 3 week trip to Italy for my newer OM System OM-1 MK II Camera. These cards are far superior at the V 90 rating and can definitely keep up with the advanced Burst Rate of the camera as well as any Video Settings I choose. OWC has always made top quality products and these cards came highly recommended from several reviewers that I respect. The price is also very reasonable. ... show more
