1.0 out of 5 starsThe product was already stolen by Amazon
Reviewed in India on 9 November 2018
The amazon has degraded itself. The package I received had the adapter of the memory card but the memory card itself was stolen before hand and I was made to pay for nothing. It's like the recent news where amazon delivered soap at place of iPhone.
The lock on the SD adapter was defective (it was loose, making it always move to 'locked' mode whenever putting it inside the SD slot), making it impossible to edit the contents on it when loaded on the computer. I had to secure it in place with a piece of cello tape to make it work.
Otherwise, it's a decent product. The microSD works fine. It is initially formatted in FAT format, limiting the max file size to 4GB. You may want to reformat it to NTFS to make sure that it can have larger file sizes.
I brought it for my mother when she complained about low storage in her phone, thankfully that complain is no where. However, I think there was no need to attach the adapter to the product as I already had one. San disk is a trusted brand and I have been using it for years therefore, bought it without a second thought. I guess the price for the product is a bit on higher side. The product is quite durable as I said I have been using the same. Storage capacity is satisfactory Overall good product.
I bought this product because it claims upto 100MBps speed. I thought it will give approx 50-70 MBPS in laptop and I believe I am not expecting too much. However in real life it gave me 1/5 speed (18 MBPS write and 20 MBPS read) of what it is promising which is very disappointing to me considering the fact that it is class 10. I think it is not having any issue with my laptop as my laptop is lightning fast.
Laptop config: Core i7 Samsun Pro SSD 256 GB RAM 16 GB
Overall rating: 3/5 because of very less speed. SanDisk 64 GB card Read speed : 20 MBPS Write speed : 18 MBPS
The speeds can exceed 10MB/s only if the number of files is less. When we transfer a folder having thousands of small files, the speed drastically falls (around 2MB/s). The speed is good only when we transfer sequentially stored objects like a whole movie. Whereas, when there are thousands of files, they are all scattered and thus make the transfer a pain. The technique would be to split the huge folder into smaller sub-folders or compress it into a zip first and then transfer it accordingly.
I'm using this in my phone for additional storage. It is having storage space of 118gb of the total 128gb. However, when i tried to transfer 7gb file in it, it took more than 15 mins to copy which is not expected as this one should be having higher transfer rate. Since, need for me is storage space, i have compromised on my transfer speed.
I think the memory card is fake. The fit and finish makes anyone doubt if we got the counterfeit card. Adaptor doesn't even fit the card well. I had to break the edges of adaptor to take out the memory card from it. Transfer speed is 3 or 4 Mbps which is not what they claim. Makes phone really slow and maybe alter memory and RAM of the phone
SANDISK ALWAYS HAVE GREAT PRODUCT WITH MONEY VALUE. BUT I ALWAYS GOT SCARE WHEN I GOT NOTIFICATION YOUR SD CARD HAS CORRUPT TAP TO FIX. NEED RESTART TO FIX THIS. NO DELETE ANY DATA YET. EVERYONE DATA VALUE HAS MORE THAN PRICE. I DON'T KNOW ITS MY MOBILE PROBLEM OR SD CARD PROBLEM. BUT MY SMARTPHONE 100% GOOD. SEARCH PROPERLY FOR THIS PROBLEM OTHERWISE YOU USE SAMSUNG SD CARD CARD. IT'S YOUR CHOICE.
