The smartctl t command starts a self test that reads every byte on the disk. |
I now know there are eight bits in a byte, and 1024 megabytes in a gigabyte. |
There are 8 bits in a byte, 1024 bytes in a kilobyte, and 1024 kilobytes in a megabyte. |
First we create a buffer that is one byte bigger than the user string and fill it with zeros. |
The time it takes to read a single byte at random is MUCH higher on a rambus system than on a DDR system. |
The interesting thing is to watch them write a subroutine that counts all the bits in a byte, then ask them to make it much, much faster. |
