USD350V Micro SD Card 512GB, U3 V30 Memory Card for Nintendo Switch/Dash cam/Security Cam/Surveillance/GoPro/Insta360/DJI/Drone/Action Cam, Up to 100MB/s, Full HD video recording w/Adapter

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.

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)

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.

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.

I love the price and the large storage space. I have had this particular sd card for only a few months, so longevity I can't say, though the reason I bought this brand was because I bought the 60gb, 5 years ago and its gone from my Note3 to my Note8 and still works perfectly in my note 8. I've upgraded to the note 20 and wanted a fresh card.

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