SanDisk Extreme III Memory Stick PRO-HG Duo Caught Speeding at 30MBps

[tttyyyyyyyy]

partitions >2gb will by deafault be formatted to FAT32 with 4kb cluster size. the trick is to format it to FAT16 (mostly referred to as just FAT) wich uses a deafault cluster size of 32kb thus marking 2GB as the max partition size. However, you can use a 4GB card with FAT16 by explicitly specifing a cluster size of 64kb.

i still dont understand how a slow card could prevent you from playing homebrew?

it does'nt prevent you from playing homebrew it just means the card is too slow to play game iso's and the more memory intensive homebrew apps

I konw and that sounds plausible, but

I already have a 4gb microSDHC class 2 and it is so slow I cant play homebrew or emulators

thats why I asked...nevermind

And to stay offTopic =)
Because I didn't find much helpful information on the internet on how to treat a 8GB card for best performance in a PSP, I just tried and formatted my card with FAT32 and a 32kb cluster-size (instead of 4kb wich is the default value for FAT32).
I might be wrong, but this IMHO should result in a 8 times smaller FAT-table and therefore significantly reduce the parsing time of the file system (directory listings for instance). After all, the prcedure of increasing the cluster size is reported to work in speeding up 4GB cards...
So formatted my card I did and I'ld recommend it to any 8GB card owner. Though no speedup is noticalble in regard to loading and saving times, but (and that was my point) the wake-up procedure from sleep mode to IRShell for instance which took ~2 annoying seconds before, now takes a mere fraction of a second. Also the initial directory view in IRShell is MUCH faster and over all the card 'feels' much more responsive (also in XMB) when reading directory indexes...

Everyone with 8GB card should give this a try i think. Would be nice to know if someone can confirm my observations...

Yeah the 8Gb MSPD definitely works when DAX's patch is applied.
I got one.

@tttyyyyyyyy

So basically to sum up your advice,you're say that it's possible to format any memory card as FAT16 system (mostly referred to as just FAT); which has a larger cluster size than the default NTFS FAT32 system which has a smaller cluster size.

Before we go any further,I'll list the system clusters to make sure we're on the same page.

FAT32 formats 2GB partitions with 4 kb clusters
FAT16 (FAT) formats 2GB partitions with 32kb clusters

But,in your own test you formatted your microSDHC 8GB class 4 with FAT32 and 32kb clusters.And that made your card more responsive.

Well,please tell me how you changed the default cluster size in the formatting process.A small tutorial would be helpful.Thanks in advance tttyyyyyyyy
