SSD disk capacity reported by manufacturer
by starbearer from LinuxQuestions.org on (#59ZJ6)
I was looking at a disk manufacturer specifications using the data sheet for a SSD disk, when I came across this disk which is being marketed as 512 GB disk.
Capacity LBA Cylinders Heads Sectors User Capacity(MB)
512GB 937703088 16383 16 63 457862
This user capacity is 457 GB or 447 maybe seen on Windows, but that's quite a reduced space, more than 10% of the overall disk capacity. I'm additionally perplexed because this is being marketed as an actual 512 GB disk.
Is this over-provisioning by the SSD disk? In which case should it be marketed as 512 GB? Or is it just that the disk is really 512 GB but on WIndows it's likely to be seen as less due to WIndows' binary system calculation?
