Actual Memory....

[funkadesi]

I am thinking of getting a new ifp-795[512 MB] or a 799[1 GB], my question is what is the ACTUAL usable space on these players..

i asked this because i had a old ifp-180t [128 MB] and i was only able to use 124 MB on it.... firmware space.. i think?

for every 128 you get about 124, do the maths for it and you will find the space of the 2 players will be about, 980Mb on the bigger one. Its because 1024kb is the official definition of a megabyte but firms started to call it 1000 to be easier. But the size of larger drives means that this "lost space" is all the lessened.

The difference in the number of bytes per "megabyte" is probably not the reason for the reduced capacity because memory chips, including flash memory, are produced in sizes that are powers of 2. The difference is seen in disk-based storage because the prefix "mega" officially means 1 million, and disk manufacturers have kept that usage in accordance with engineering tradition, but powers of 2 are more suitable for computers, and thus computer memory uses a different definition. (To try to differentiate between them, there are actually two different official sets of units for storage: 1 KB = 1000 bytes, while 1 KiB = 2^10 bytes).

The actual cause of the apparent lost space is probably the overhead of storing the filesystem for FAT16.
