Transcend 1TB microSDXC Micro SD Card A2 V30 UHS-I U3 C10, Up to 100MB/s, 4K UHD Video Memory Card with Adapter for Nintendo Switch, Steam Deck, ROG Ally, MSI Claw, GoPro, DJI, Insta360, Action Camera

It's a memory card. It works fine, I needed it for an older device I had and it worked fine. How much more can you say. Quality is good but I would not rely on it for a job (but at 4gb, what kind of job would you do on this?). It does what it should, what more can I say.

I probably should have gone for the 126g model but settled for the 64g because I have an NVR for primary video storage and almost never need to access video from the camera. They record HD video without a problem. Response\playback is very snappy.

Very nice for the price, Added to 2 dashcams. Speed should be good, temp range is good. We shall see how many cycles it will last but rated for 10,000 insertion/removal cycles. I'll report back if/when they croak.TLC NAND flash.In a 1gb SEQ Q32T1 test in crystaldiskmarkSustained Read =~96mb/sSustained Write =~23.3mb/s-----------------------------------------------------------------------CrystalDiskMark 5.5.0 x64 (C) 2007-2017 hiyohiyoCrystal Dew World : http://crystalmark.info/-----------------------------------------------------------------------* MB/s = 1,000,000 bytes/s [SATA/600 = 600,000,000 bytes/s]* KB = 1000 bytes, KiB = 1024 bytesSequential Read (Q= 32,T= 1) : 96.749 MB/sSequential Write (Q= 32,T= 1) : 23.303 MB/sRandom Read 4KiB (Q= 32,T= 1) : 11.125 MB/s [ 2716.1 IOPS]Random Write 4KiB (Q= 32,T= 1) : 1.591 MB/s [ 388.4 IOPS]Sequential Read (T= 1) : 96.050 MB/sSequential Write (T= 1) : 18.242 MB/sRandom Read 4KiB (Q= 1,T= 1) : 10.766 MB/s [ 2628.4 IOPS]Random Write 4KiB (Q= 1,T= 1) : 1.347 MB/s [ 328.9 IOPS]Test : 1024 MiB [F: 0.0% (0.0/29.8 GiB)] (x2) [Interval=5 sec]Date : 2018/07/05 23:26:15OS : Windows 10 Professional [10.0 Build 17134] (x64)

This is for a car DVR. It seems to work.

Upon receiving I formatted and inserted it into my dash cam. After using it for a full day, here's what I noted. The first is that the integrity of the video is good. The second is that it is a bit slow for video use in my opinion. While watching the playback I noted multiple jumps that I don't experience with my SanDisk Mobile Ultra. As for the "Endurance", that remains to be seen.

Worked great copying my favorite music to it to play on my portable bluetooth speaker. I don't like using bluetooth much, so having a good portable speaker with TF/MicroSD card capable is great for me. This Transcend 32GB microSD Memory Card is great and I would recommend it to my family members and friends.

Needed an microSD Class 10 memory card for my older Garmin GPS in order to download the USA in one place. This card was the least expensive that I found meeting my needs and the price was only $7.00 plus sakes tax. I just put it into the slot on the GPS and download the map I needed. No problems and another job off the to do list.

High quality images no matter how many times the camera overwrites.
