Public bug reported:
it seems that sata drives are being slow on laptops. i have had a few to play
with and discovered slow read throughputs, i.e. 30MB/s maximum for at least 2
disks tested, which were hitachi made. there are a whole lot of websites
reporting troubles with sata drives.
this should probably be worked over as it seems to affect boot time very much.
(a dual core AMD turion x2 64bit booting as fast or even a bit slower than a
intel celeron m 1,6GHz with 32 bit and only one core does not feel right)
it however seems not only to depend on the chipset, as this laptop here uses
ICH7 and the other one was nvidia chipset.
maybe it could be helpful to see though the posts on the forums. there seems to
be some trouble with the chipset driver, as some of the issues dissappear when
enabling raid as the disk controller on bios. which will not happen on laptops
due to limited bioses.
