Transcend is not so bad but, I have faced some many issues with the virus, as it is ready to get and its totally virus porn and the speed of copying is too late and it may be because of high consumed memory inside.some heating issue wen I use it more than half hour and it was easy to carry and that was not bad to hold in pocket.it has really a bad heating issue and once a day I use it more than some four hours and it heats like an iron box and this should be think like and need to fix this as the main priority.moreover it is good in function and delays or lags while copies or moving or deleting file in that drive.
