Transcend TS64GSDU3

Advantages: Speed

Disadvantages: Price

Comment: A review for those who think that this memory card lacks speed. 1 byte = 8 bits. 4k has a video stream of 50 or 100 Mbps (namely megabits, not megabytes). Even if this memory card supports a recording speed of 50 MB / s, this is already enough to record video with a stream of 400 Mbit / s. This speed will not be enough except for a professional camera that records 4K video 60fps with a stream of 600 Mbps, i.e. camcorder for several hundred thousand rubles.

Advantages: Huge recording speed. The card produces about 90 megaBytes per second for writing! I use on Fuji X-T3 4K 400 Mbps = 50 megabytes per second. At the moment, this is the highest speed in cameras up to 250,000 rubles. I see no reason to take more expensive cards if there is almost double the supply for recording high-quality 4k video

Disadvantages: Didn't find

Comment:

Advantages: + suitable for 4K recording; + the price is not sky-high; + a version of the card with 128 GB of onboard memory is available (which is a plus because faster cards are usually limited to 64 GB, at least for now).

Disadvantages: - I would like 10 percent more read and write speed, since most cameras and camcorders claim that they still shoot 4K at a speed of 100 Mb / s, and not 90-95 Mb / s, so such a speed of a card can in theory become bottleneck.

Comment: In fact, the card is quite capable of working as a memory for recording 4K video, however, the inconsistency of marketing techniques of manufacturers of video equipment and memory cards does not allow realizing this on the fly: the former overestimate the video bitrates, although usually 4K video does not smell of 100Mb / s, but the latter, on the contrary, are afraid to overestimate the bandwidth of their creations.

Advantages: Speed ​​and price.

Disadvantages: I haven't found it yet, because I haven't used it yet.

Comment: I bought this card, tested it with CrystalDisk, here's what happened: --------------------------------------- ------------------- Sequential Read: 92.255 MB / s Sequential Write: 68.710 MB / s Test: 1000 MB [E: 0.0% (0.0 / 60.3 GB)] ( x5)

Advantages: I liked the volume of the card for such a price. I record full shd 60 frames, it works flawlessly. 4K hasn't tried recording yet. I am very pleased with the card.

Disadvantages: There is nothing to complain about yet.

Comment: Tired of carrying a bunch of small cards, it is much more convenient to take one volumetric one.

Advantages: Reliability. High speed data transfer. Acceptable price. Suitable for high definition video recording (1080 25p or 50p) of most camcorders and DSLRs that use SD.

Disadvantages: For such a price I could not find something to find fault with. And the comments in the comments.

Comment: I bought two pieces together with a video camera (for there are two slots in the camera), which writes 1080 50p video with a stream of 35 Mbps. I decided to take with a margin of space and speed. And I didn’t regret it. It is very comfortable to merge information from cards at high speed. It falls short of the nominal values ​​indicated on the packaging. Reading stated 95 Mbit / s, in fact 75-80. But this is not critical, it is still very fast. And maybe my card reader is a bit short. The recording is stated to be 60 Mbit / s, in fact the average recording speed is 52-53 Mbit / s, which, in principle, is also normal. They say it is suitable for recording 4k video, but this is not entirely true. This is only true for budget 4k camcorders. The middle class of cameras writes a stream above 50 Mbps, as far as I know, so these cards are not for them. There is no point in writing about movie cameras here. Those who shoot, for example, on blackmagic, should understand that such maps are meaningless. A DSLR is an excellent choice. The fast write speed to the maximum will reveal the rate of fire of even a cool DSLR that works on SD cards.

Advantages: Practicality.

Disadvantages: Declared speed is less than expected.

Comment:

Advantages: Quality and price, fast delivery.

Disadvantages: didn't notice

Comment: I took it for the phone, while there are no complaints, the price is acceptable, it costs more in stores. I bought it for the phone and did not regret it, the speed for downloading information is very pleasing.
