Defraging memory

MTANGEN · 01-01-04, 02:36 PM

Is it possible (or advisable?) to defrag one's CF or SD memory? I know that I have put alot in it and removed alot from it so that it is probably quite defragmented.

If it is possible, where can one find programs or utilities to do this?

most people here say it doesn't need to be done. You can do on you home pc if you have a card reader. Or check out storage tools it has a free trial period. you can download at handango, I do it from time to time and it seems to help, if for no other reason than I think it does.

Thanks, Bulldog and good luck with the website!

Or just move everything off the storage card to main memory and back on.

Howard2k, very interesting but I assume you move it off CF/SD memory to the laptop/desktop memory because PPC main memory would be to large to fit it all?

Pocket Mechanic defragments a Flash card. It does many other things too. I won Pocket Mechanic from the aximsite, lol. Pocket Mechanic is GREAT!! :D

That would work, but honestly you are wasting your time. You won't gain much from this exercise, but if it makes you feel better go ahead.

exercise???? Are you talking about Pocket Mechanic, or just defragmenting in general??

defragmenting in general, solid state media doesn't really gain improvements as much as disk media can. But as I said, if it makes you feel better go ahead, even sugar pills work sometimes. ;)

Well i actually noticed that after i defragmented my CF card via Pocket Mechanic, it saved things faster, and the performence was better.

Well, I hate to disagree with you, but you can't notice any difference after a defrag on solid state media. Unlike a hard drive there is no wait for the heads to move so moving the data around does not increase speed. I can increase how much data you can store on the card, but not the access speed. As I said, sugar pill...

Ok, whatever, your the smart one. But it says in the detailed description that the defragmentation increases performance and you can't accuse the software developer of being WRONG, now can you?

It makes me feel better & I like that when a card gets messed up that I can fix it.
I'll take the sugar pill, but do I get to choose the red one?

Quoted from THIS POST, from THIS (rather lengthy) THREAD.

All-in-all, a very good tretise on Fragmentation.

Quote:

The story is different for memory fragmentation, because memory access does not suffer from the data access delays that affect hard drive performance - hard drives are mechanical devices.

To access memory merely requires that the correct address is used for the required memory location. Memory access speed is therefore not affected by fragmentation, because the data is accessed by applying a series of memory addresses as required. The actual bits in the address field that have to change makes no difference whatsoever to a solid state device such as memory.

It's just as quick to change 8 address bits as it is to change 1. Defragmenting memory is just a waste of effort and shouldn't affect performance in any way.

I can accuse them of trying to make a buck. :D
