Transcend128GB SDXC/SDHC 300S Memory Card TS128GSDC300S

Great value for money

Just got it and put it inside my camera. Works very well without any problem.

Works fine, good deal for the money. I stuck it in my laptop and leave it there for extra storage

I'm rating this 3 stars because of the way it's advertised. The description says that it can get up to 95MB/s read and 45MB/s writing.I tested mine as soon as I got it with a PC and a USB connection where you plug the SD directly to an adapter, so a camera isn't involved.This is a V30 rated SD, and it meets that standard (writing at 30MB/s), but when I was writing a large file to it (about 3GB), which is a good simulation of being in a camera while making a video in HD or UHD, it averaged 31MB/s. So, it meets the V30 spec, but it's no better than that, so for my SD it's nowhere close to the description on Amazon where it says up to 45MB/s. If you were to look at the percentage of error in that statement, it's 50%, which is incredibly BAD.For reading, I went from this SD to a mechanical RAID that gives me close to 260MB/s writing, so plenty of speed to test the ability for reading off this SD. I only got 72MB/s reading off this and writing to the RAID. I then wrote to the RAID from another mechanical drive and I was writing at the speed that the other drive could read at, which is about 175MB/s.I do this kind of testing because it's real world, whereas running test software isn't. I also have Windows 7, still, and Windows 7 always shows you the average write time for the write op you are doing, so it's a great indicator of what happened over the entire write op. Since reading is listed at up to 95MB/s and I only got 72MB/s, the error there is about 25%.Mind you, this is an error in the description on the Amazon listing for this item, it may not be an error in what the manufacturer lists. Once again, this is a V30 SD which is only required to write at 30MB/s. I didn't bother trying to find out what the read speed is rated at by the manufacture, and they often won't list it anyway. What I do know is if I were a manufacturer and I gave specs., and my specs were off by 25% and 50%, I'd have a whole bunch of dissatisfied customers, many of who would be wanting to return the product.So, buy this item to save money, but don't think you're getting a great deal and you might actually be able to use this to capture UHD video in the more RAW formats that really require an SD that can capture at 45MB/s or higher, and this is certainly the case for different video capture formats for the newer DSLRs that are capturing UHD video.This is an older SD, so you also have to understand that age is affecting how long it will last you, so maybe it's better to simply buy the newer version of this product and pay a little more money. It you need to capture at something like 240-280Mbs, you're best off buying a V60 spec'd SD and pay the extra money, knowing your SD can keep up. Or, buy one that's proven to write at 45MB/s on average, and there are those out there, as it says so on the product. The only thing this product has on it that say anything about the speed is V30.

I was quite skeptical of this SD Card since it was advertised as a 512gb card and fairly speedy; and very, very cheap. When I received it, I thoroughly tested it by adding enough large files to prove that it had the advertised capacity and close to the advertised speed.I re-formatted this card to NTFS so I could use it in my new laptop computer as a substitute for a larger SSD. It is probably much slower than the slowest SSD, but it works fine for my purposes. I'm very happy with it.

love it

I have been using Transcend memory cards for about 15 years. They are reliable and as fast as advertised.

Works as advertised

Transcend 300S 32GB SDHC UHS-I Class 10 Memoria Flash, para fines normales (en mi caso una cámara que máximo graba en 720p y toma fotos de 12megapixeles), es una excelente memoria, mi cámara no tuvo ningún problema en detectarla y el tiempo de guardado de los vídeos se redujo a poco menos de la mitad (comparado con una adata de las mismas características (SDHC UHS-I Class 10) pero de 16Gb, la cual la cámara siempre pedía se reformateara).

Bought for a friend, seems to be ok

Bought 3 since the prices are down (3x 1tb). I've been using them nearly everyday, mostly for 4K video and so far it has been working incredibly good. Not a single drop in transfer rate (from SD to macbook) and no corrupt file so far. I haven't had a chance to test the speed but the transfer rate from mac to SD is about 70mb/s which is good enough for me. I'm very happy (so far!!)

Haven't fully tested the 1tb capacity. But what I've used seems fine so far. Can record 4k video too! Though probably not very high quality 4k, it's good enough for me!

Works just fine, but the real selling point was the price compared to other 512GB SD cards.
