increasing block size, CF
« on: October 27, 2011, 01:32:02 PM »
if we increase the block size from 512bytes to 4Kb (or more), would OS write files in larger chunks?
iirc, someone said PFS always uses 512byte block size, is there a way to overcome that?

I ask because those cheap CF cards that are so popular in Amiga world, probably use MLC instead of SLC flash.

So using larger logical block (equal to physical) would be better ?

Nobody has yet reported what happens when you use a device with physical blocksize different from 512. It may already fail on that level, so thinking about what happens with logical block sizes is of no use yet.


I see, thanks for the reply.
I had thought that using larger logical blocks would prevent having two files in same CF block.
perhaps that wouldn't be wise anyway, given how small Amiga files usually are.

edit:
btw, I found this simple method for flash block size: http://kim.oyhus.no/FlashBlockSize.html
haven't tried it yet. beware, dd might destroy data on drive if not used properly.
