I have been using my TH55 for years with a black memory stick marked:
"Sony Memory Stick PRO 2GB MagicGate".
I just bought a new black memory stick marked:
"Sony Memory Stick PRO Duo MagicGate Mark2" which I am using with the silver/white/blue MSAC-M2 adaptor.
One of the things which irritates me about the TH55 is the slow speed of card accesses... so I did a few quick comparisons accessing databases and copying files and it seemed that the new memory stick might have up to double the read and write performance of the old one. I decided to download VFSMARK to try and get a more accurate idea.
Here are the results I got:
VFSMark Results old stick
File Create: 29%
File Delete: 22%
File Write: 8%
File Read: 425%
File Seek: 97%
DB Export: 27%
DB Import: 246%
Record Access: 209%
Resource Access: 197%
VFSMark: 140
VFSMark Results New stick
File Create: 345%
File Delete: 289%
File Write: 296%
File Read: 539%
File Seek: 437%
DB Export: 415%
DB Import: 403%
Record Access: 524%
Resource Access: 512%
VFSMark: 417
(The site I downloaded the utility from claims it is VFSMARK 1.1 though the readme stated 1.0... if it makes a difference).
So comparing with the tables at http://www.palmclub.nl/tips/vfsbenchmark/ it looks like the new stick is faster. However, I was very surprised by the poor write performance of the old stick as detected by VFSMARK (but not obvious in use). Probably it is just an unreliable benchmark though I wonder if perhaps performance declines with age due to wear levelling or perhaps there is some erroring and correction going on.
(Both sticks have the same data on them)
One other thing I was faintly remember was the old FAT patch to be able to access memory sticks larger thatn 2GB. If I remember correctly it had a fast read speed but slower write speed or vice versa. Maybe the new memory sticks mitigate the performance issue? However, the fact that the patch breaks Audioplayer would probably still stop me from using it.
