[Debian-eeepc-devel] max solidstate disk speed?

Hello all,

I was reading trough my debian sid boot dmesg and saw the following lines:

ata2.00: ATA-4: SILICONMOTION SM223AC, , max UDMA/66
ata2.00: 7815024 sectors, multi 0: LBA
ata2.00: limited to UDMA/33 due to 40-wire cable
ata2.00: configured for UDMA/33

I think the ssd is not running on his max speed, is this true, and what 
can we do about it?

Kind regards,

Jelle
