Who needs hard drives

That said, you should ALWAYS back up your data (photos or whatever) whether stored on removable media, internal storage on a phone or table or a hard drive on a computer.

I tried two expensive thumb drives in the 1T+ range and neither would work reliably

Haven’t noticed any slowness during Normal use but the transfer speed between my hard drive and microSD card could be faster.

this is the first time i try more than 128Gb micro SD card, 400GB just like a Hard drive, you don't need to worry and bring more SD card when you travel anywhere
