Transcend 64GB microSDXC 300S Class 10 Memory Card with up to 95/45 MB/s (for Smartphones, Digital Camers and Nintendo Consoles) without SD Adapter TS64GUSD300S

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.

Does exactly as described great value and storage.

Good

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.

Some initial teething trouble, which was just a case of finding an SD adaptor that housed it snuggly (seemed fussier than other cards). For the low price, the card works quickly enough and performs well even with a non-lightweight Linux distro running on it. Of course as it’s not a high endurance card, it can’t be expected to last very long under such heavy duress. Time will tell!Overall for normal storage use, it’s a great buy, and will probably buy again at some point.

Bought this to setup all day recording in one of my IP camera after my other card failed. Super happy, nice and cheap and works without issue.

I recently bought this to upgrade my cousin's 2DS to a 64GB card so they can play around with modding and homebrew. While the 2DS/3DS have class 4 slots, this is overkill in that regard; it is brilliant when transferring files over from the PC to the card. Works well, what more can I say. I also have the 128GB version in my Nintendo Switch and that has been going strong for many years.

Its a storage card which stores at a reasonable price. 20 years ago it would be science fiction!Edit changed this to 3 stars as it would not work in the cheap dashcam I bought but a SanDisk one did. Worked fine in my mobile though
