I have a Thinkpad X40 that I'd like to replace the Hitachi hard drive
on. The drive is 1"8 with a normal 2"5 PATA disk connector on the

bought a Compact Flash adapter and a Transcend 133X 32 GByte Compact
Flash.
I installed Fedora 9 on the Compact Flash, with a small boot partition
and then one large encrypted LVM partition where I put the swap
partition and an ext3 file system. This turned out to be bog slow,
write speed to the ext3 file system seem to be about 1MByte/s which is
just horrible. Since Transcend claims 45MByte/s read bandwidth and
16MByte/s write bandwidth, this seems much too low.
CF is not an SSD. A CF is designed and spec'd to store large images.
Neither CF nor USB thumb drives are intended as a primary system
hard drive. They work great for transferring data between machines
but no filesystem or tuning will make them perform with the same
characteristics you expect of your primary hard drive.
And I won't be surprised if they are optimized for FAT. Many SD cards
are - the first N sectors are often faster there, and in case of large
cards they may be mapped to SLC NAND, while the rest is mapped
to MLC NAND. I may suspect that CF may do something similar.
