Samsung T5 500GB USB External Solid State Drive (MU-PA500B/AM)

Has a very small physical footprint, close to 500Gb usable capacity, can be formatted to Mac (EXT3) or Windows (NTFS) same as any other standard drive, and is fast under USB 3.x. I did not use any included software, best recommendation is to avoid it, particularly if you are on OSX. For those wishing to use it as external storage for a Raspberry Pi, it works on my Pi 3 without any additional power required other than that provided by the Pi's USB port itself.

No issues writing or reading files from a Samsung Tab S3 or Galaxy S8. Both devices were able to power the T5 from the devices USB connection. I also use it to do a system mirror of my PC (T5 needs reformatted to a NTFS format for this option) in less than a half hour (300GB of data). Additionally, it can be used to play files on a Roku 3 streaming device. In summary, I got more than what I thought I paid for when I purchased the T5. After reading many reviews I was doubtful it would work with the Android devices and only if supplemental power supply was used to power the SSD. I was pleasantly surprised that there were no issues.

Great drive. Ultra fast, small and reliable. I have a couple of these and are way faster than the traditional USB drives. They are smaller than the other drives in capacity but it makes up for it in speed.
