I have used many brands of pendrives except Sony. I thought of giving it a shot. I bought a pendrives online and paid around 600rs for a 32Gb USB 3.0 drive.
First of all it is on quite expensive side as in this price we can get an OTG pendrive with 3.0 support that too of same capacity.
Also the transfer speeds were not good, sometimes very pathetic.
So it’s better to buy other brands then buying Sony that too on cheaper price.
Sony is best in other gadgets but not I pendrives section.
