[/quote]Can you run Crystal DiskMark on these 1.8 inch SSD and report the results?[/quote]
Test result from 51nb: http://www.51nb.com/forum/thread-777699-1-2.html

The SSD from Kingspec (link Below) seems to need 5v Does the X40/41 not use 3.3v? http://www.kingspec.com/ According to the explanation from the representive of kingspec, the voltage range is 3.3v-5v. Moreover, ASAX and Kingspec have update the prices for 1.8 ide ssd 32G, the latest prices are 699C...

ASAX has changed the price for 1.8 IDE 32G SSD from 599CNY to 999CNY. That is unacceptable...
But another company seems to participate in the 1.8 IDE SSD group. see http://www.kingspec.com/
I am sure in nearly future (maybe half year) we can get better and cheaper 1.8 IDE SSD.

In China we now have 1.8 SSD especially for x4 series.Look at the pics:
