OK, I have taken the plunge and ordered a SanDisk Extreme III CF card (133x card) that has ~20MB/sec Read and Write speeds with the intention of replacing my internal 4Gb Microdrive on my Zaurus.

http://www.sandisk.com/Products/Item(1182)...tFlash_4GB.aspx

I chose this card because it seems to offer good value for money (about £140 GBP in the UK now), top performance, and a 10 year manufacturers warranty.

Note that there is a Transcend 8Gb card also available for about the same price now, however, the warranty isn't lifetime it is 1,000,000 write cycles and the operational temperature is lower.. I decided to err on the side of caution therefore and go with this card which is known to have write spreading technologies and may yield a considerably longer life (maybe).

I also didn't need the 8Gb version because all my Multimedia stuff is on my iPod.. I prefer to do it this way then at least when the battery is dead from listening to music and watching movies I still have my Zaurus smile.gif

I believe the write levelling on this card will probably (even with constant running) see out the life of this Zaurus but I guess that only remains to be seen.

When the card arrives I will do some benchmarks and provide some information on runtime with both the original Microdrive and this card fitted since the power consumption is also supposed to be a fraction of the Microdrive.

Benchmarks will probably come first since I can perform those with the card in the additional CF slot.

but daaaaamn, I'm going to ruin my 'uptime' figures. I get disappointed if I have to reboot it more than once per month tongue.gif

More soon,

-Andy

(btw. in case you are wondering why I have been quiet here it's because my Zaurus 'just works smile.gif' and does everything I need it to at the moment... currently it's even running Ruby on Rails with MYSQL - it will be nice to see what performance is like with the new drive for this)

I'm very interested here, because I just finished doing all the spelunking into my own SL-C3000, and I feel ready (hardware-wise) to begin replacing my own hard disk. I've chosen a 8 Gb Seagate hark disk (I found one for about $140, which seemed about $40 too expensive, but no one else seemed to have it at all). That's a whale of a lot cheaper than a 8Gb flash would be, I think it's more reliable, and I haven't checked the speed, but isn't the hard disk faster than a huge flash like that? Since I can't even hear my present hard disk, and the Seagate is spec'ed at no louder, I figure that the flash and the hard disk are both effectively silent in running, right?

Somebody on the openbsd.org mailing lists mentioned that they got errors with the 8Gb Seagate Microdrives and suggested that it may be a power issue... They ended up reutilising the 8Gb drive in something else.

The goal of this exercise really is performance and battery life, however, I shall document the replacement process and liberally add photos.

I'm very interested in your findings. I've just measured my 3200 battery life today, and got the same results: 4 h. uptime (9:29 - 13:29) with the lid closed and the wifi card connected. I used a cron job to log the apm status each minute. Apm showed a 100% for an hour, 95% for five minutes and 91% the rest of the time :-)

Have you measured charging time? For me, it takes many hours (12, maybe, I'm not sure) to get the yellow led off. I charge with OpenBSD running. I'm wondering if this could also improve with a flash card instead of a microdrive.

In the eagerness that I have experienced whilst waiting for the new card (possibly Tuesday this week) I have started to benchmark the existing configuration and I will compare this against the new card when I have it/fit it.

here are the results with the Microdrive...

sorry but wifi uses more power than lan card! test with no wifi and log it every min to a log file

Well the card just arrived and I popped it into my Zaurus..

Firstly, a nice surprise, the card is somewhat higher capacity than the Microdrive 4g != 4g it seems tongue.gif

The new card appears to be 8005536 sectors instead of 7999488 like the Microdrive. I wanted to just dd the old installation over so I opted to make wd1a the same size as wd0a and increase my swap space. At the moment the card is running the bonnie++ test. I will then reboot it and dd the image and do a trial boot off the external CF slot.

(it does mean of course that I can't backup the whole CF card with dd but I can still dd wd0a->wd1a with Microdrive in the external slot later)

all went well finally, man it's a swine to get some of the screws out and there is a nice little 'requires soldering iron' part that nobody mentions.

There is actually a copper foil earth strap near the IR transceiver that on some units is a longer wire. If you have a unit with the longer wire you can get the board out.. if you have a unit with the copper foil (like mine) you must unsolder it and resolder later.

My dd though seems to have overwritten the drive parameters with the Microdrive ones and although the unit 'looks good' and is definitely fast the disklabel reports Microdrive label and stats.

I have just reinitialised the drive and am now using cp -Rp to transfer the OpenBSD installation from the Microdrive to the SanDisk card... more later.

Cool, please let us know how does it fire up against the microdrive.
P.S. My C1000 didn't have copper foil...

Will do as soon as it has finished copying (full set of tests as previously documented).

If you take a look at this pic..

http://photos4.flickr.com/7220418_4f9406c0ce_b.jpg

(from the original Japanese disassembly site) you can see that the 3000 has a wire strap (top right), whereas on the 1000 in the picture has the Copper Foil (looks like a rectangular copper blob) on the piccy.

It should be noted that I spoke to Trisoft about this asking advice (after taking full responsibility and voiding warranty etc.) they mentioned they tried it with an Ultra II card and had about 1 week of runtime before the card failed... lets hope I get better results than that smile.gif

I see a wire strap on C3000, but It's hard to see anything on that photo... Do you see it here:

Ok here are the results so far, only just started the battery test so we will have to see how long that takes.

Lid closed, using Socket Low Power CF 10/100 Ethernet card run top across remote ssh connection and removed charger cable. Time is measured between power cable being removed and the time that the time stops on the top display.

Full results are now posted above... interestingly whilst idling (disk runs constantly) on OpenBSD the battery life is almost exactly the same with this card.

Really strange. Always 4 hours exactly. I'm testing battery life in my 3200 this time with no CF card attached. I'm wondering if the battery is really empty and is not possible to start the unit without powering it. Or if after powering the unit just enough to start it, battery runs for hours (4 again?). This smells to "feature" :-)
