Do communicators support MMCA version 4.0 MMC cards?

14 replies · 3,256 views · Started 03 February 2005

MMCplus� cards, named MMCplus, MMCA version 4.0, support x1, x4 and x8 bus widths. They are just now coming to mass market. Operating at 52 MHz in x8 bit mode, data can be transferred at up to 52 Mbyte/sec., a 20-fold improvement from the previous standards: http://www.mmca.org/press/MMCA-SpecV-4.pdf

Do Nokia 9500/9300 benefit from them, or are these slow machines too slow/do not have 8 bit bus, that it doesn't make any difference compared to older crop of MMC cards?

Wouldn't make any noticeable difference anyway. I don't understand why you care about MMC speeds... What's wrong with the current speed? What benefit would a speedier MMC card give you? I just tried opening a 13MB encyclopedia file from my MMC card - it only takes like half a second, and then I tried opening another encyclopedia (same size) that I have stored on the C: drive - it works exactly the same.

Sloooow

I was wondering just that, that's why I wanted to know what the real experts say about it. If Communicators could utilize the 20x speed, it were more than valuable for me. Their general impression as a whole is remarkably slow.

Which is sad news for me.

Some examples:

When I open my favorite book of only 1 Mb - and notice: in native EPOC format - it takes 25 seconds(!) to open it - which is slower than opening the same file in my Psion in Psion's native format. And the book does not have any tables or pictures but plain simple text.

When I search a word in SlovoEd English Lexical Database Full (which is in main memory), then AFTER I have ended my typing, it still takes the same 25 seconds(!) to show the result. Abysmally slow!

No wonder that I desperately seek some (seemingly nonexistent) tricks to get my 9300 work even as fast as my seven Psions I have had since a decade ago.

The cards are Backwards Compatble so yes they shouldl work fine although if you phone doesent support MMCA4 then it will still run at 3.8 speeds.

25 SECONDS, WTF??? :con?

I haven't used the native EPOC format, just Word, but I guess it's all the converting that makes it slow. I'd strongly suggest that you do your eBook reading in another app like MobiReader - it supports .txt, .doc, .prc formats. Or simply just avoid that EXIT button and leave the app/book running in the background.

I haven't used SlovoEd either, so I cannot comment on that piece of software.

I have all my books and dictionaries/encyclopedias in .prc (Mobipocket) format. The Mobipocket Reader app itself is a rather slow piece of software (always been - on any platform), but looking up a word in a dictionary/encyclopedia works pretty much instantly.

A different MMC card wouldn't make any difference whatsoever. It's all a matter of software. Sounds like you are doing things the hardest way possible, using the slowest file formats/software available...

The hard part is that I have no eBooks, and converting my own Word files to eBook format seems to be a complicated route - haven't tested it, only read about it. -- Because of your comment it seems that I have to test how these eBook readers could handle the texts, instead of 9300's own Documents app.
(P.S. after quick testing Mobireader, which appears to be a free bait to a commercial eBook-fyke - seems that I'll drop the eBook way)

I have all my texts converted from Word files, then saved in EPOC format via Save as -> Change format -> epoc/app (because conversion from but especially back to Word takes forever - I do not exaggerate much!). I read these texts with 9300's own Document app.

The conversion process is very cumbersome because there is no batch conversion option, like Psions have, and I have _hundreds_ of Word files which I should convert to epoc, because I must have my reference library everywhere with me - haven't practically even touched the surface of the conversion job yet...

To keep even my most important files (texts & other important apps) in memory is impossible simply because of the sheer volume of them.

Mobipocket reader will read plain text files, html files, and mobipocket ebooks as standard. TBH I'd expect opening a 1meg file in any reader on a portable device to be slow, that's a lot of data to handle, lets face it that wouldn't open instantly on a PC either. Not seen any 1mb text documents, but I know spreadsheet docs in Excel can take 10seconds+ to open.

If we suppose an equivalent start position where in typical 2800+ AMD desktop computer (not portable, of course!) Word is loaded but not yet the Word data file (some of my 1Mb books). The loading of the 1 Mb data file takes only one second - and it really comes from hard disk, not from cache. Big difference compared with tottering steps of 9300. Understandable, but so sad, so sad.

Hmms 2Ghz+ CPU with a FSB of 300Mhz or faster with a data throughput rate no doubt in megabytes. Vs a portable computer with a 150Mhz CPU, FSB speed I don't know but lets assume based on a P150 33Mhz, and an equivalently deminished throughput rate...... even if you factor in the fact that windoze is bulky, bloated and slow you can still see where the PC may just have an advantage.

Same scenario - MobiReader is loaded, but not yet the Prc data file (13MB). The loading of the data file takes only 0.5 - 1 second, really! 😉

Just convert your files to a more usable format already. It isn't complicated at all. Mobipocket has their own converter you can use, and if you don't like that one I'm sure there are dozens of other programs you can use. Or just use a simple text file or whatever.

Thank you both, Raven and SwitchBlade, for being so persistent!

In spite of my wife's desperation of my sitting still before my computer at 4:30 AM , I made an experiment by exporting in desktop PC my Word file to text file, and lo and behold, that file really opened up in one second in 9300 in Mobireader (plus the time it took Mobireader to load itself up). To move around is somewhat slow but much more tolerable, especially when the bookmark function seems to work, and the dreaded effect of breaking lines with different zooms levels did not come true.

I had already given up, but you have given me the motivation to continue to search the best way to batch prosess, partly anyway, the other big files!

Beauty of this site is that if you've got a problem, someone else has no doubt had it too and if you are lucky found a sensible solution.

Epilogue:

Mobipocket Office Companion Pro Symbian 2.1 build 4412 helped me to batch convert hundreds of my files very easily to eBook.prc format, and Mobipocket Reader Pro v.4.8 seems to be a relatively elegant reading program. The problem of the sheer volume of my conversion needing files and the extreme sluggishness of my first solution hereby both solved, satisfaction maximized, discussion forums praised, helpers appreciated!

I can't save images in highest quality from the camera app straight to the (1gb) MMC card, if I switch the camera folder back to internal memory, then it works fine... 😞
Very annoying as the camera renames the images from 01 if the folder is empty, meaning I can't move all the files over to the MMC without renaming them. 😞
