Prime 128GB SDXC UHS-II Memory Card – 300MB/s Read, 105MB/s Write | Ideal for 8K, 4K, HDR, and 360º Video | High-Performance SD Card for Cameras

Have been using various Delkin card versions forever, have always been reliable and durable. I don’t use large capacity cards so, Delkin Prime 128GB card is good size and has enough capacity. The read/write is fast enough for most photo/video projects and good price.

Good price. Good quality. Fast delivery. Excellent service.

I bought this card for use in my recently acquired Fuji X-100F. Previously I had used a couple of SanDisk cards which were reliable, but seemed slow in my X-Pro1. Thinking the performance was more due to the camera, I hoped they would perform better in the X-100F. The performance seemed the same to me, though I didn’t perform any precise tests. This 64GB Delkin is, subjectively, WAY faster than the SanDisk 32GB. It formatted instantly and write speed is noticeably much faster. I primarily shoot stills, including JPG and JPG+RAW, only occasionally shoot video; the X-100F is primarily designed as a street shooter for still photography. So I don’t know how this card performs for high end video. I have not used this card extensively yet, though I will use it as my primary card now, carrying a backup card, of course.

Upgraded to a mirrorless camera and needed a high capacity, fast SD card. Filled that requirement very well and was flawless on first vacation. Fine with stills and video.

So far so good! Formatted easy and works great in my Sony a7C camera. Writes and reads plenty fast. Delkin is becoming very well known in the digital camera world for reliability. I do recommend these SD cards.

UPDATE: Dont buy this card to work with the GH5 high bit rates. In my wedding I had today I decided to use it as a second card for relay recording. And because I put that card in last the GH5 defaulted to start recording on this card. It is so slow. It does not keep up with V30 cards. I have a Samsung 128GB 100MB/s (U3) MicroSD EVO that is way faster. It took a considerable 5 to 10 seconds at the end of each recording for the camera to write to this card. With my Samsung cards it is maybe a second if that. Most of the time it is instant. I bought this SD card to work with my GH5's high bit rate recording as it states you need a V60 or above SD card to handle the fast data transfer. This card did not work for me. I would not recommend it to anyone looking to use this card for your GH5. It obviously can not measure up to the V60 speed it claims. Too late to send back for a refund once I found out.

Memory cards from Delkin have proven to be reliable photographic partners. I have never used their warranty service, but it is good to know it is there if needed.

Packaged well and works flawlessly

Die angegeben Transferraten sind pure Fantasie. Leseraten liegen unter 100 MB/s, etwa auf UHS-I Niveau. Schreibraten bei etwa 60 MB/s. Formatiert mit einer Canon 5D IV in Fat32. Fazit: Chinamüll, Nicht kaufen

Not cheap but fast enough for photos and 150 mbps 4K home video up to 60p. I Use it for recording video with Canon XF400 and have had no problem with write speed so far. I have not tested it for higher bit rates. Also used it in Canon EOS-R camera for both photo and video and it is comfortably fast and reliable so far.

I bought two of these cards to use in my Panasonic GH5 camera with it's 400mbps (50MB/s) codec. One of them works perfectly, but the other one is too slow for this application, despite the card being rated at 60MB/s continuous write speed. Very disappointing for cards that cost £100+ each. I will be trying a different brand (Sony or Sandisk) to see if I can find something more reliable.

Works great. Overkill for my Sony A7ii which can't utilize the full speed of the card. But never the less it is working at the max for the camera. Very happy.

I didn't do any extensive testing but this card has worked on two shoots when used in the Fuji X-T3 recording 400Mbit video. It has a rating of V60 and it seems like it might be slightly higher at about 70-72MB/s write speed (according to the blackmagic speed test). Very pleased.
