a USB 3.0 Flash Drive

Why don’t we get complete storage on our devices & drives

When Companies sell their storage media, be a memory card, flash drive, or a hard drive we don’t get the complete..
The truth behind that is storage media when they sell us is defined as in 10^power but the actual way on a machine to calculate is 2^power..
The companies sell storage worth GBs but they provide as (1GB = 1 * 10^9), if we divide it by 1024^3 we’ll get the actual storage space of a flash drive.

Example.. To calculate storage of 4GB flash drive :
4GB (as per sale) = (4 x 10^9) bytes
=> 4 x 1000000000 = 4000000000bytes
but actually 4GB equals 4000000000 / 1024^3
=> 3.725… GB

so you only get 93.132 % of shown amount.

Difference between Mbps and MBps

Mega bits per Second
-> Up/Down Load speed
-> Web based Transfer speed

Mega Bytes per Second
 -> file & storage
-> 1MBytes = 1 x 8 Mbits = 8Mbits

Example – To find the time 100MB file takes to download @ 56 Kbps or 56 KB/s download speed
  We first need to convert 100MB to Kbits ->
100MB = 1024KB
= 100MB * 1024 KiloBytes
= 102400 * 1024 Bytes
= 104857600 * 8 Bits = 838860800 Bits
Time taken to download 100MB or 838860800 Bits @ 56 Kilo bit per second  / s or 56000 bit per second
= 838860800 / 56000
= 14979.657 Seconds = 249.67 minutes

100MB = 1024KB
= 100MB * 1024  KiloBytes
= 102400 * 1024 Bytes
= 104857600 Bytes
Time taken to download 100MB or 104857600 Bytes @ 56 Kilo Byte/s
= 10475760 / 56000
= 187.067 Seconds =3.11 minutes
