Oh..and that was with 630Mhz. At 900Mhz speeds are a lot bigger

I suspected this was so! What is the difference in transfer rate between the two speeds?
Offline
BTW, can someone show an SD speed comparison at 900MHz?
Offline
Yeah. RAM drive operating at 100 MHz FSB versus 70 MHz FSB will definitely make it show even faster!

It would be great if you also measured write performance!
You can use free Aida32... it's old I know, but it has nice Disk Bench plug-in. You have to enable write bench in the options.
Tests like:
- Linear read/write
- Random read/write
- Average access
would be really nice 
Download Aida32 from here:
http://www.softpedia.com/get/System/Sys … AIDA.shtml
Newer versions are know as Everest - http://www.lavalys.com/index.php?lang=en - and have the same plugin.
Beware! It will destroy all data and partitions on tested drive!! So make Backup before test! And make sure you select the correct drive for testing.
Keep the bechmarks coming

Can someone tests the a-data 8 and 16 gb class 6 (turbo) ?
And Lacie little 60gb(3600rpm) or lacie skwarim 60g(4200rpm)?
thanks

If I used an SDHC to install an operating system on, would it be slower than using the built-in harddrive?

Simpletech SD card 256MB
Tested with Everest Ultimate 4.20
Average linear read: 9.6MB/s
Random read: 0 (weird results)
Average read access: 0.77ms
Average linear write: 6.84MB/s
Random write: Min 3.91, Max 8.33, Avg: 6.71MB/s
Average write access: 30ms
I'll test my 2GB SD when I get my digital camera back.

Has anyone tested MMC Plus (4.x) cards?
I saw good offer for Transcend 4GB, but still no information of the EEE's card-reader bus-width, clock speeds and driver support.
Offline
I tested the Transcend Class 6 4GB SDHC and it appears to be faster than the 8 GB version. Note: this is not the more expensive 150X version.
Results:
Transfer rate: 14.3 MB/s (min), 16.7 MB/s (max), 16.6 MB/s (avg)
Access time: 0.6 ms
Burst rate: 14.7 MB/s
CPU util: 12.1 %

Any idea about the write speed Yitch?

N.B. Same message posted in another thread ...
Not measured with XP.
----------------------------------------------------------
A-DATA SDHC 4GB Class 6 Turbo:
Read speed: ~17MB/sec
Write speed: ~1.3MB/sec
Measured with "dd" and various setups for source/sink and block size.
While read speed is ok, writing is dead slow. Class 6? Guaranteed 6MB/sec write speed? D'oh ...
Also card needs some force to pull out of the slot, something is catching (lock tip?).

Out of curiosity, is there currently or is anyone planning a buyers guide for the Eee where people can link what they recommend you buy for either SDHC/MMC transfer speed or compatibility, with links to where you bought it? I'm sure people have bought lots of various brand cards by now, so a thread where they are all laid out with simple pros/cons might be nice. Or is there one and I've totally missed it?

I dont have any high capacity SD cards to test yet, so have been using whatever mem cards I have at hand - just to compare. using HD tune. Final test is with an external terrabyte Hard drive connected via the USB instead of firewire (How i wish the eeepc had a firewire!)

Its an external Pair of 500GB hard drives, from Western Digital - Usually comes with firewire 800 / 400, USB2 interface in raid0.

Using nbench.exe (an old yet accurate disk benchmark app) set to do a 100MB test:
My Kingston 4GB Class 2 SDHC card was rated at ~15 MB/sec for reading, and ~7 MB/sec for writing.
The internal SSD was rated at 23 MB/sec for reading, and 14 MB/sec for writing.

I cannot believe the usb flash disks are faster than in the internal ssd. 
Offline
Have you tried installing XP on it?
Offline
I would be very interested to see XP running faster on the external flash drive as opposed to the local one.
