Compact Flash

I've seen a few articles online where network appliances are running Compact Flash rather than a hard drive.  There's also a few people who have loaded the Linux Kernel onto compact flash...and if I remember correctly there was a company called L-Inc who were using something similar on their desktop offerings.

The information I have gathered says that compact flash is considerably faster than any hard disk (this information may be dated, I haven't compared specifications)--The main 2 drawbacks are #1-the capacity of the compact flash #2-the limited number of write/flush/write

Unlike hard disks, compact flash cards can only be written, flushed (or contents deleted) and then re-written 100,000 times---so if you put your pagefile onto compactflash it would be toasted in a matter of minutes.

But I am very curious to see what kind of performance you might see with the following setup:

-C:\ (1 gig compactflash) Win XP
-D:\ sata disk or raid0 with program files and page file

The price of compact flash has gone down so much that I believe you can get a 1 gig card for very cheap.  There is an adapter that allows the card to plugin to a standard IDE interface that runs about $20.  I may have to test this out.

On the old dated information that I found on this using ata 66--compact flash clocked:

2ms seek time, 2.5 megabyte per second transfer.
(note Seagate Barracude #ST3160023AS SATA disk has 8.5 MS seek rate)

It may not hold up against SATA...but a simple benchmark may be in order.

L-inc. is Liebermann. http://www.go-l.com. A very expensive company, but they created PURAM which is said to be 1,000X faster than a hard drive.

Yeah to my understanding L-Inc uses Solid State disks, which is comparable to using compact flash...their machines look cool, but they are too pricey.

Actually last I heard L-Inc wasn't doing business anymore.  We tried to order some monitors from them quite awhile back and after jerking us around for a few months saying they were backordered, we were told they were discontinued.

Which is why we went with these:
