Transcend USD300S A1 128GB UHS-I U3 with V30 Micro SD Memory Card up to 100/40 MB/s (TS128GUSD300S)

Received the card prior to estimated date.About the card i've taken a gamble, with regards to its specs in price comparison to that of SanDisk and Samsung Evo.Nearly half the price in that V30 segment (128GB), with 5 years universal warrantyMainly needed it for my GoPro Hero6 and a card with a write speed capable of recording 4k on the go.

Excellent.Transcend is a trustable brand like sandisk & samsung.- It is having 117 GB storage space with 28.7mbps maximum copying speed (not 128gb space with 95mbps).- Copied 90gb data and tested, No issues. Good working.- no recovery rx software found inside this card, it is fake information.- no adopter was given with this card.- For Successful Data transfer, we should always use data adopter with laptop's data adopter slot.- If using card reader with USB slot , card will give errors and it asks for a format after copying data. its common in this cards. So must use card reader slot with data adopter.-1370/- is worth the price.

Awesome card (128 GB). Tested using an app on my Redmi Note 7 Pro. App wrote test files to fill it completely and then read them back to verify. Below are the results-Thu May 09 21:54:01 GMT+05:30 2019Finished verification of 117.5GB, 0.00KB errors found.Average Read Speed: 56.6 MB/s. Average Write Speed: 31.6 MB/s.I'm sure this card will perform even faster if used on a laptop. Great value of money @ 1300Rs.RecoveRx software is not provided in card but you can download it freely from their website.

Awesome speed

Friends plz don't buy this product.. waste of money..i buy this sd @1300 .. it doesn't work..it shows sd card error.. my files have bee lost.. don't buy this product.. waste of money

Works great with my Osmo action cam. Reading and writing speed is up to the mark. Only thing that I will need from this product is a card reader along with it.Will recommend this product! Value for money in this price range.

I purchase 750 inr.It is good price and quority.

Stupidity at its best. I formatted this card as internal memory and migrated data as anyone struggling with low storage would. And violla I could see my files and previews, but nothing could be opened. And what's worse is there is no option to return even when it was delivered today only. It's only possible to get a replacement. Do you think I can even take the risk of using this stupid thing after such as out of the world performance one!!!!!

This is a superficial breakdown of 30 minutes spent with the card, so take it with a grain of salt.Using it with an adapter into a laptop equipped with a decent SSD, you can expect write speeds that constantly dip as low as 9-10 MB/s and go upwards to 28 MB/s. Read speeds usually sit in the high 20s. Haven't tested it straight into a device, so speeds might improve, as shown by another customer with pictures (70+ mb).As for the capacity, as I see this argument popping up over and over again, please educate yourself why the advertised capacity by the manufacturer is different than the one showed by your computer. A simple google search will give you multiple articles regarding this.For all intents and purposes storage is calculated as you would weight, distance etc, by adding zeros to the end.so 1 Gigabyte (GB) = 1,000 megabytes (MB) etc.However due to how computers work, they will not show these values, but instead:1 Gigabyte (GB) = 1,024 megabytes etcThe bigger the drive is, the more capacity is "lost" in the listing of your device.128 gb = 1,099,511,627,776 bit1,099,511,627,776 bit = 137,438,953,472 byte137,438,953,472 byte = 134,217,728 kilobyte134,217,728 kilobyte = 131,072 megabyte131,072 megabyte = 128 gigabyteI made a quick calculation (which could be slightly incorrect, failed math):The amount you "lose" is as fallows:Gigabyte difference = 73,741,824 bytesSince per GB your are "losing" 73,741,824 bytes, then 73,741,824 bytes x 128 GB = 9,438,953,472 bytes, which converted to GB equals: 8.79071 GB (as shown in the picture).Windows machine shows 117 but if we add the "missing" 8.7gb = 125.7, which is closer to the advertised capacity.Also this might be true for write/read speeds as well, and the actual product does not advertise 95MB/s, rather "up to" which is correct.Does the job, but I would use it for complex write and read situations. Only really useful for mobiles and other hand held devices.

This Transcend card gives satisfactory performance, I think.I use it in the microSD slot of my Surface Pro 6 to provide bulk storage.Please see the attached benchmark photos.In my testing, it gave slower write speeds when formatted as NTFS (vs exFAT), but I think it is still OK.Random access R/W speeds are not too bad, better than a HDD of a few years ago.For GBP 14.95, 128 GB, it's OK.Only four stars because it does not achieve the advertised 95 MB/s read speed.

Absolutely gutted, started transferring photos from my mobile to the card and it just stopped, already transferred all of my photos and was just finishing off with my music and video files.The card became corrupt and lost all of my files, not bothered about my music too much but my photos of my holiday and daughters prom are gone for good.Will be looking to return this once I have had my IT friend look to see if anything can be recovered 😭

I got a pair of these for a couple of Tablets. I read that they might need reformatting to get the max capacity but I didn't have any issue with them at all showed up as 118GB storage available. I think that's pretty common to loose some of the space with rounding fo bytes off to GB. Next day delivery was spot on!

Bought a couple of these for Victure Security Outdoor Cameras, that record with audio at 1080p (don't know bitrate, sorry). Following formatting in the camera, they seem to work. I am not running them with full-time recording but with motion detection, which hopefully should avoid the cards wearing out too soon – which is a real concern with these less-expensive cards.If I run into any problems I'll update this review.Simple, basic packaging with no wasted SD card adaptor provided, as with some other micro-SD cards.
