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

[Art]

I have a feeling the PSP could take advantage f the speed in USB mode,
since the USB controller is a separate device.

[bah]

Art: I didn't notice any increase in speed from a regular blue sandisk to an Ultra II.

Card readers write to ultra II (and possibly standard cards) quicker than the PSP, so I doubt you would see any benefit at all with the PSP as USB mass storage connected to a PC or with the PSP itself.

[tttyyyyyyyy]

Oh my....

I'd recommend a 8GB microSDHC Card and an adaptor to MSPD instead of a high-priced MSPD...at least thats what I've done...

It is all good, but the main question has not been answered, do 8GB memory sticks work with the PSP (any version)?

From my research, it seems Dark_Alex created an SE plug-in that adds this ability along with improvements with others, but I'm not 100% sure.

Although I haven't tried an 8 GB memstick in my PSP since they became cheaper only in the past few months, I have read months ago that 8 GB Memsticks work in the PSP ... there was an update in one of the 3xx Firmwares by $ony and Dark and his crew made it available in the CFW, too ...

Anyway ... all these high speed Sticks are of no use for us ... and not for most of the ppl. out their, either ... why?

Well ... 90 % of the card readers I've had the pleasure to work with support fast speeds ... the cheap ones hardly can offer a speed that even uses 100 % of the normal cards' standard speed. U can see the differences if u take an ordinary 10 - 15 EUR non-name drive and compare it to a more expensive one made by a well-known company ... huge differences, even with standard flash chips.

I do not know how fast a PSP can write on those sticks, but since a freakin' 500 MB game takes an eternety longer to be writen via USB cable and PSP compared to my built-in laptop card writer by Acer, I somehow doubt that it can be even close to "high speed" ...

Sad, but true ...

But we should all keep in mind that the PSP was never made to write with very fast speeds ... the only huge load of data it may be meant to copy were ~ 500 MB movie files ... not 1,5 GB games or even 3 or 4 of them

I can confirm that a microSDHC 8GB card does work in my PSP (phat, 3.71M33-4, 1.50 Kernel addon) without any problems.

[wwboy]

really cool but to expensive

But as far as I know the card you have can only go up to a Class 4 (4mb minimum read write time). What class is your card (it will say on the actual card with a 2,4,or 6 in a circle)?I uploaded a memory stick tester.I'd appreacite it if you would test your card and post the results in this thread,since I already have a 4gb microSDHC class 2 and it is so slow I cant play homebrew or emulators

My card is class4.

It might be possible to speed things up by using 8kb clusters instead of 4kb on a 8gb-card thus reducing the FAT-table from 8MB to 4MB (if i recall correctly)...
...but maybe thats just plain wrong, i dunno...

How would a slow card not let you play homebrew?

did u try to speed up your 4gb stick by formatting it to fat16 with a 64kb cluster size?

[Dunpeal1978]

I read about speeding it up by formatting it as FAT,but your saying if I format it as FAT16 it will be even faster?
