I recently upgraded my computer, and I've posted alot of good information about it.

Any DSL users have their systems running on these new high speed CF cards yet?  I'm curious to see if you can get transfer rates higher than what I got.

I have pics up too, if you're curious.

I'm using a Sandisk Extreme IV compact flash card; 4GB.  I like it a lot.

Yeh, I ran two of them, one in each ide.
Transcend and Adata 266x (udma mode 4).
They're a bit cheaper than Sandisk Extremes.

Wether CF cards or USB drives, performance varies greatly between brands. There are some 'fast' drives (i.e read or write fast) that perform horribly for many small files (slow random access speed) and where the 'slow' drives handle with ease.

The various brands don't advertise these differences openly, it's pretty much a guessing game.

How did you get transfers higher than 6.5MB/s under linux?

I mean, even though I'm getting such slow transfer rates this thing is still way faster than my 7200 rpm hard drive in everything from apps to the internet to booting.  I blame access times, but regardless.........

Do you think it's my OS that's limiting me?  I love how SuSE is full featured, and I absolutely adore how simple YaST is to get everything configured, and all in one spot.  I tried several linuxes' on this card, but not DSL.  I'll have to try it when I do some upgrades in the next couple of months.  I think I'd rather have the speed than the ease of use.

no special configuration required with DSL, except the 'DMA' boot line code. I'm using DSL 2.1b.

You can tweak hard drives using hdparm (search for hdparm performance on google), but I didn't need to.

Yeah, in order to get proper booting I am required to pass the IDE=NODMA command through GRUB.

I wish I didn't have to do that, but I dont think that's what's keeping my transfers at 6.5MB/s.

I picked up a second CF/IDE adapter for use in another computer, found that the original one didn't properly support UDMA.
