Question about TRUE space on SSD's

post #1 of 9
Thread Starter 
Hey,

I have a very simple question.

You know how regular HDD's are sold as having 500GB of space, but have 460GB of available space? (http://answers.yahoo.com/question/in...8072357AAQ4qWt)

Do SSD's have this same issue?

This is because a computer measures one GB as 1000 kb, HDD manufacturers measure as 1024kb.

Partially right, reverse that (computers binary addressing would see it as 1024kb/GB, while HDD manufacturers use 1000kb/GB).

There have been several class action law suits against the manufacturers (unsucessful, all of them) concerning this.

No...
There is a hardware limitation that causes certain data blocks to be unable to be used. Each flash drive/HDD/SSD/memory card is manufactured with a capacity for x GB, but the actual capacity is different because a hardware limitation/manufacturing technique (??? can't remember) causes it to be lower.

Man, I remember reading about this years ago and now I can't remember a thing.

EDIT: My 931GB "1TB" HDD--931(1024)=953344
953344/1000 = 953GB
If your claim is true, I'd still be "ripped off" of 50GB.

As to Kiwasian: Yes, the formatting (creation of the MFT- master file table, partition creation & such) does take up space. But the majority of the loss is in the way that drive manufacturers pull the wool over everyones eyes with their "different" measurement system than the accepted norm. Detailed in the minutes of the court cases.

Edited for case names only (because the rest is a rather long read)
