Who needs an SL-C3000? 2GB SD!!
« Reply #15 on: October 18, 2004, 04:22:58 pm »
Solid state cards are more durable than their microdrive cousins, but the microdrives can handle much more abuse than a traditional hard drive (due primarily to the very low mass of the components).

Dropping an operating device with a microdrive is a valid concern and could potentially damage the drive. However just moving a device (even abruptly) with an operating microdrive will not result in any damage or loss of data (unless you move the device by hitting it with a large hammer  ). Current microdrives are rated for operating shock of 200G  (equivalent to about a 30cm [1 ft]) drop onto a hard surface. When the drive is not actively reading or writing, it spins down and parks - at which point shock tolerance goes up to 2000G (a 3m [10 ft] drop) ... about the same as Sandisk's shock rating for their solid state CF cards.

It is important to keep in mind that *any* storage card in a PDA can suffer catastrophic failure (I have a small box of dead solid-state CF cards so I can say with some confidence that they're not indestructable) and should be backed up on a regular basis!

The benchmarks for sd speed on oz 3.5.1 seem higher.  Anyway, I haven't had any trouble playing video from my sd on either sharp or oz on my 5600 (pxa250). My el cheapo 2.2 gig microdrive is another story entirely.....

kopsis, do you still have a binary for the benchmark program? If so, could you send me a copy please? I would like to run some tests of my own to compare sd and high speed sd, and to see if there is any difference if I put the sd card in a cf sd adapter.
If you don't have it could you tell me where and how to get it on my Z please?
What Zaurus did you use to do the tests?
I would like to try and keep my tests as close as possible to yours, so that they can be at least slightly comparable.

Thanks
Simon

I think this post will give you most of what you're looking for. Searching the forums for "bonnie" will yield you a reasonably concise list of threads where these benchmarks have been discussed.
