SanDiskExtreme PRO microSDXC UHS-I Memory Card 1 TB + Adapter & RescuePRO Deluxe (for Smartphones, Action Cameras or Drones, A2, Class 10, V30, U3, 200 MB/s Transfer)

I have a total of seven of these cards and have had uniformly reliable service from them. I use them in my Olympus/OM Systems cameras, two cards per camera. That gives me 2 TBytes storage per camera which is sufficient to go on a two week trip w/o worrying about downloading photos while enroute. While I agree that theoretically 27 contacts per card is less reliable than 9 contacts per card I have no issues whatsoever with any of the cards. These cards are fast enough to keep up with my cameras even shooting 4K video or sequence photos of moving subjects.

1tb works as advertised

Pros:- High Capacity.- Fastest Read/Write times of all the cards on the Amazon site.- Quick Delivery.- Easy installation in a Samsung Galaxy S20+ phone.- Records 4K video streams with no buffering.Cons:- Expensive SD card.- Lack of availability. I could only buy one card.I have a lot of large files and do backups of files from the phone to my servers so I need not only large capacity but high data transfer speeds. Above all, I need reliability. The Sandisk Extreme Pro meets my criterion in all respects. Sandisk has always provided me with a superior reliable product in the past so I am willing to pay more for the performance and reliability. Samsung does not offer a 1TB Micro SD card so there is only Sandisk as the supplier of high capacity, high performance SD cards. No other vendor comes close to the state Read/Write speeds of the Sandisk Extreme Pro. I have tried most of the vendors (not the no-name brands offered on Amazon) but all of them either failed within months because of the high read/write loads, or just didn't have high enough read/write speeds to meet my requirements. Only Samsung made an SD card that came closer the the Sandisk card in terms of performance and reliability. Unfortunately, the largest micro SD card that Samsumg offers is a 512 GB card. If you have ever lost your data to a SD card failure, the higher cost of a better card means almost nothing.The only problem I had with the Sandisk Etreme Pro 1TB card was that Amazon.com only had 1 card in stock when I ordered it. Since I needed 2 cards, I had to settle for ordering a Sandisk Extreme 1TB card which has slightly lower performance specs than the Extreme Pro (190 MB/sec Read vs. 200 MB/sec Read).In conclusion; if performance and reliability with the highest capacity are your requirements and cost is not really a consideration then the Sandisk Extreme Pro is the only card you want to get.

I use these for my Steam Deck. Large capacity, great value, great speed

Works as expected

I use it with my Nintendo Switch and it perfect.

I've always used Sandisk memory as I have never had an issue with them. This was the fastest micro SD card in 1TB.

It’s a decent SD card I use it on my ally X. I think it’s over priced to be honest. I was never able to get above 100mbs read or write with crystaldiskmark. I tried different variations of trials and size all came out the same. I seen others have gotten better and some about the same. I wouldn’t recommend trying to play games off it. I only have it on there for easy file transfer as I use it as a gaming handheld and pc for miscellaneous things. The capacity is great but the speeds are questionable.
