Hard drive manufacturers use metric measurements when selling hard drive capacities. That is, 1 kilobyte = 1,000 bytes, 1 megabyte = 1,000 kilobytes, 1 gigabyte = 1,000 megabytes, and 1 terabyte = 1,000 gigabytes, and so on. The operating system like macOS X or Linux uses decimal bytes when reporting storage space, so a 512GB SSD will show up as 512GB in Mac and Linux OS, for instance. However, The windows OS uses binary bytes, which means when you install a 512,000,000,000 bytes storage drive into Windows OS, the computer converts the number of bytes into gigabytes by dividing by 1024 through the scare instead of dividing by 1000. Doing the math, this is what we end up with: 512,000,000,000 Bytes / 1,024 = 500,000,000 actual Kilobytes500,000,000 KB / 1,024 = 488,281 actual Megabytes488,281 MB / 1,024 = 476 actual Gigabytes This is why a 512GB SSD will be correctly reported by a Windows computer as 476GB.

No SATA SSD was not designed to be hot-pluggable. You must power off the system and then install your SSD. In the end, you have to initiate/partition the SSD.
