While portable slim hard drives are meant for carrying around in a backpack or laptop bag, all but the largest 32 TB and 64 TB external hard drives (featured here above) are still small enough for easy transport in a backpack or briefcase.
Sadly, it depends. Hard drives are advertised in Gigabytes being 10^9 bytes. But operating systems measure Gigabytes using 2^30 bytes. So 1GB in hard drive advertised size is 1,000,000,000 bytes. 1MB is 1,024*1,024 bytes. So 1GB = 953MB.
