Netac Micro SD Card 64GB 3 Packs, MicroSDHC Memory Card, TF Card, 4K Full HD Video Recording, UHS-I, 667X, C10, U3, A1, V30, for Camera, Smartphone, Security System

Good and cheap. Works fine for my dash cam and action cam which only takes max 32GB, easy to use and seems speedy enough for the task. It says waterproof, magnet proof and indestructible I will put this to the test. You can reuse the plastic part of the packaging as card holder which is a bonus. I like this multipack.Update. 09022022 one of SD cards just died. It developed bad sectors and it's unusable. Two others still work ok.

I've been using these for a while now, and they're every bit as good as the better known big brands. I have on in my phone and several for use in my Mirrorless camera and compact too. Netac is my go to brand for memory cards now,

The CrystalDiskMark results attached to this review relate to the 64GB cards I received in June 2020. As you can see they performed respectfully in a short test at least, easily suggesting that their V30 rating for dashcams, drones etc should be attainable although their random read / write speeds for smaller files is lower than my current average. Performance wise these cards are comparible to a number of brands in this price range and competition is fierce which is why I have only given 4 stars - for the same price MyMemory own branded cards have slightly faster write speeds and a better random I/O performance with a lifetime warranty. These cards are probably best suited for applications that involve larger files where fast write speeds are important (such as dashcams) followed by moderate to regular use (such as in a phone storing music and photos) but not so much for applications or holding an OS (eg Raspberry Pi) where the random transfer characteristics may disappoint. It is too soon to tell how reliable they are and my use-case for these cards will be very light duty and not in a dashcam.In other news the cards look quite distinctive so if you fancy something different or want to be able to easily differentiate between your cards these are worth considering.

Not been used yet but did check them on my laptop & they were recognised immediately & show that they are the correct capacity so obviously can't comment on reliability. Fast delivery & a very good price I think. Recommended.

I bought these because of the price despite what other people said about that one or two don't seem to work but in my case I must have been lucky as all three worked. But as for how these will last is anybody's guess.But if I was to take an educated guess, should last way longer than SanDisk Ultra Micro SD Card of the same size (two of them that I bought only seem to last for a few months before they stopped working in different ways). So overall they should last for three years.

Seems fine, was the recommended type for my CCTV, and not glitched nor corrupted so all good. Don't know if you can get cheaper ones but doesnt really matter as not something I'll hopefully need to buy often.

I bought these to go in an action camera, they are the correct size as I checked them with an app to make sure they were indeed 32gb each. very good value for money

Amazing memory cards for such a small price! The read and write speeds as advertised and a fantastic alternative from your usual big hitters. "10/10 - Would buy again"
