Advantages: The card was purchased in the fall of 2016. Now, January 2018, the card is still successfully working in the actively operated smartphone, periodically pulling it out to insert it into the laptop. After the purchase there were tests in the crystal disk, the stated characteristics correspond more than completely. I was looking specifically for the MLC-NAND memory, because she is reliable

Disadvantages: they are not. she is perfect

Comment: Unfortunately, such cards are now hard enough to find, initially I took for a smartphone, when the question of buying a card for an auto-video recorder arose, it was decided to take it as good as this one, but after a careful search it turned out that more modern cards are either inferior in price or parameters, although they are more expensive , in the end I decided to take the same, but they are only available in one place, you will have to look for a replacement.

Upd: found all the same in the city of availability. Inserted in the DVR PlayMe Back. It’s certainly early to talk about reliability when used in the recorder, but the video in the highest quality is written without brakes.

Advantages: Quality. Reliable brand.

Disadvantages: Not found! Price.

Comment: This card is time tested. I have such a card for two years on a SONY HDR-AS200V action camera. Loaded not childish. Under water at a depth of 1.5 meters, as well as at high temperatures in the sun, when shaking during ATV rides, in the mountains, and even in winter in hard frost. She does not care how much, keeps a steady stream of records.

Advantages: The speed of information exchange. Estimated lifetime warranty from Transend. Practically not deceived with real volume - 30.1 gigs or 32386318366 bytes

Comment: Good speed card. I really want to buy a USB 3.0 card reader and test it, but for now I tested on USB 2.0 and there are such indicators (according to Windows) 17 MB / s recording. reading 20 MB / s. Recorded a video file weighing 1 gig.
Here I bought a USB 3.0 card reader and tested the speed of writing and reading - it turned out 67 MB / s and 92 MB / s, respectively.

Advantages: Great card. Very fast, also on the MLC NAND, which implies a very good durability.

Disadvantages: Price, of course.
