defragmenting the BIS? recommended?

axim_wannabe · 07-08-05, 08:11 PM

call me weird or something - but do we need to defragment the BIS? would it really add to performance?

and if so, how?

thanks!!!

PS: yes, i guess im a performance freak...

It's imposible to do. Just Memory card

No point. But if you're anal about that sort of thing you can just move the data out of BIS and move it back in.

BIS is generally so much slower than main memory and removable media that you would probably not see any difference in performance whatsoever, even if it was possible to defrag it.

I thought that Flash (ROM) Memory doesnt fragment in the first place?

The point it's not that it "not worth it". It's simply imposible to do.

No it's not. If you move the files off the BIS and then move them back on, the individual files will not be fragmented.

Ok if you do this like that. But if you use Pocket Mechanic, it doesn't allow defrag of the BIS, only SD of CF.

No. The BIS is random access memory. If the system accesses the first location and then access the last location there is no delay or lag. On a hard drive the disc's head has to move to the new location, so there is a lag.

The same is true for SD and CF flash memory; random access memory. On the other hand, if you buy a microdrive CF card then you might want to defrag that, since it's a tiny rotating magnetic disc with a read/write head.

Um, last time I checked the BIS is ROM and so are all types of Flash memory. RAM requires a continuous charge, such as the RAM in the Axim. BIS does not, neither does any kind of flash memory.

Yeah, after I posted that I was thinking that it might be confusing. When I used the term "random access memory" what I meant is that RAM and ROM are random access, which they are.

A disc is not random access in the sense that there's a latency between reading sector A and sector B, depending on where they are on the disc.

With RAM and ROM, reading byte A and byte B has the same amount of latency regardless of where the two bytes are in memory; they could be next to each other or at opposite ends of memory.

With a disc it has to wait for the disc to spin the proper sector under the head, and if the sector is on a different track it has to move the head to that track. (I said that backwards; the sequence is that the head first moves to the correct track, then it waits for the proper sector to come round under it.)
