[10x High Endurance] Gigastone Industrial 8GB 5-Pack MLC Micro SD Card, Full HD Video Recording, Security Cam, Dash Cam, Surveillance Compatible 85MB/s, U1 C10, with Adapter [5-Yrs Free Data Recovery]

Excellent just what we needed for our switch

These cards are pretty fast which is usually traded off with high endurance cards that focus on reliability rather than speed. I have 5 packs of the 8GB and 16GB variants as shown by the attached benchmarks and it is worth noting that the 16GB cards exceed the requirements of the A1 spec whereas the 8GB cards do not. I am using these in Raspberry Pis so the speed is clearly not that important however I am using them in applications where the Pi is on 24/7 with few writes so long term reliability is my aim. It is too soon to know how reliable these are but they are up against some stiff opposition since I usually use Samsung Pro Endurance cards which have never failed me yet. My 4 star rating is based on the fact that in 32GB sizes the cost between these and the Samsung card is small and I am wary of using a lesser known brand. But who knows, they all work and seem stable so far.I see some reviewers commenting that these cards have failed when used with 3D printers. Please note that in my experience their controllers are often powered from USB sockets on the printer itself which is not advisable especially with Raspberry Pis and the like where SD card corruption is likely the fault of a noisy, poorly regulated supply or someone using a phone charger instead. Personally I have never had a card fail in any of my Pi based projects and at the time of writing I have 6 out of 10 of these cards in use 24/7 with no issues.

Does exactly what it says on the tin. Delivered early. Tested on H2test app. Capacity 116 GB correct for 128GB card.Bill

Good value for money. I have bough twice, giving 4 cards. For some reason there is an SD adapter for each card. I would prefer to get cheaper cards and abandon historic interfaces. With the money saved I could buy one quality adapter or ever I need it.

I bought these for my Nextbase dash cam however they would not work. My dash cam came up with replace with a branded quality SD card. Wasted money. Not happy.

These are not 128gb as they were 116gb

As always a fast delivery service, these have been great to use on my various 3D-Printers, they hold lots of prints and saves lots of time, Thanks

These are fast, like fast, on a pi 4 it’s boot and in use time is excellent. 5 star...
