Delkin DevicesPower 128GB SDXC UHS-II Memory Card – 300MB/s Read, 250MB/s Write | Ideal for 8K, 4K, HDR, and 360 Video | High-Performance SD Card for Cameras

These are additions to the same SD Cards previously purchased. I have no issues when used for high frame rate shooting of birds.

Super Happy With This Delkin 64gb Card. Great In my A7riv. Just as fast clearing buffer in my a7riv camera as Sony tough cards. At half the price. I would buy again with no issues.

Also, in the past, Delkin's customer service is awesome and just top notch!!

Works great. No problems ever.

Decided to give it a try after seeing Delkin cards next to Sony/SanDisk in the performance tests for in body write speed for Sony A7RIV.Performed my personal real life test - using Sony A7RIV, shooting 61MP RAW Uncomressed + JPEG (~122MB+31MB) until the buffer is full, waiting till the buffer clears.Delkin v90 (uhs-ii) 128GB : 32 shots -> ~36 secondsSony Tough v90 (uhs-ii) 64GB : 32 shots -> ~34 secondsTranscend v90 (uhs-ii) 64GB : 32 shots -> ~46 secondsSanDisk Extreme V30/A2 (uhs-i) 170/95 read/write 128GB : 31 shots -> 1 minute 22 secondsI haven't tried Lexar/ProGrade/others, as Sony is known leader and Delkin was ~5% slower only, which is Ok taking price into comparison. When I was buying 128GB Delkin was ~130$ vs Sony ~200$.

I purchased this card for my Canon R5. I found a website that tested and measures SD card performance. This SD II card at the storage capacity was one of the best performers. So far the card as performed well.

I purchased this sd card in November... It quit working all together so I sent it back in December... I still haven't received payment for the return... Worst purchase ever!Update: 06/15/23 still no refund from seller or way to request a refund again from Amazon.

I was almost lured into buying one of the much more expensive Sony and Lexar options, but someone did a thorough investigation, connecting the Sony SD controller to their computer, and running tests with many different SD cards. These came second, and indeed, I can verify that they are very quick on my Sony A7R IV. I use a Sony USB UHS-II card reader, and read speeds are very quick also.

Really fast write speeds and download speeds are significantly faster to the computer. Great upgrade!

Este SD é UHS-II e é bastante rápido, mas pelo preço encontra-se mais rápido por isso acabei por devolver. Seja como for, se encontrarem a bom preço, recomendo porque é mesmo muito rápido.

Brilliant and so fast. No buffering at all for me. Buying more as available

Arrivata in confezione bulk e già il colore non era quello corretto.La scheda arrivata è nera invece del blu delkin delle serie PRO. Scartata arriva la sorpresa, mancano i pin dell' UHS-II.Neanche provata in macchina, avviato subito il reso. Spero che AMAZON faccia più attenzione in futuro.

Been using 4 of these with the Fuji X-T3 exclusively because they meet the specs for the camera's 4k 400mbps All-i codec as well as the 4k 60p and 120fps 1080 modes, never had a problem with any of the cards -plus they have a crazy good warranty soooo, why buy anything else?
