Micro SD Card Bondisk 256GB ARY JEA 256GB High Speed Class 10 Micro SD SDXC Card with Adapter

THIS IS NOT CLASS 10! FALSE ADVERTISING ALERT! Class 10 has a ‘minimum’ speed of 10MB/s to qualify as class 10 (Hence the name), and most run at around 30-50MB/s.But this has an absolute highest transfer rate of 7MB/s (most of the time it struggles to get above 4-5MB/s). I also had problems initialising it and it didn’t even come properly preformated.I was only able to format it as ExFAT when installed into my old laptop which has a built in SDCard slot (else I received block write errors).My newer laptop has only USB-c and was unable to format this with ExFAT using my Anker USB3 SDCard adapter.I have other Samsung class 10’s that I can format perfectly in the Anker USB adapter and write data at over 50MB/s (tested with the same files in the same laptop).This is not just cheap and nasty, at half the price of the competitors devices this is less than 1/10 the performance of others which are only twice the price.The read performance is even worse at struggling to achieve more than 3MB/s. So this is basically useless for any modern equipment.You can see in the photos that even the text printing on the top is not printed properly..For the users who said that their photos and videos were corrupted, this would have been because a camera’s small internal memory buffer needs to be flushed to the SD card quickly enough before moving onto other internal routines, however as this card is so slow it will be unable to write or read quickly enough and the files will be incomplete as a result.Do not buy this!I am requesting a refund for this under terms of false advertising. Amazon please consider removing this listing.

This is an 8gb card that has been hacked to appear to be 256gb. Running flash memory diagnostics confirmed that attempting to write past 8gb would result in total loss of data. DONT USE THIS CARD, YOU WILL LOOSE YOUR DATA / PHOTOS / VIDEOS / ETC..

Unbranded rubbish, serves me right for buying cheap. Won't hold data, won't load data, slow, and locks up my MP3 player and my camera. IF YOU VALUE YOUR DATA BUY PROPER BRANDED cd CARDS.

Not the class 10 one that is in the description it's a cheap rubbish one .Don't waste your time.

As other's have said, don't waste your time. What you get is an unbranded card marked Micro SD HC, which is an immediate giveaway. HC only went up to 32GB, for above you need XC and that's not what you get.Suspect it's a 32GB under the hood, even though it says 256GB. Woudn't hold data, files disappear, really slow (< 5MB/s).Avoid.

This has not worked for me. I have tried to copy a large number of photos from my PC and it has repeatedly failed. The write speed is very low, OK, but after 20Gb or so it crashes and what has been copied is lost. Is it really 256Gb? I have nver had such problems with any other card and I own several.

Awful! Stopped working just after the return date ended! And it only worked on a few devices which is very odd! Do not buy!

dont waste ur time buying this, it doesnt work or very poor performance
