SSD errors=remount-ro

[Pawan]

hoj,

kupil som si tento ssd disk http://www.kingston.com/ssd/v-series.asp?id=1 a dal som ho do mojho notebooku.. boot super kratky 20.05 a vypinanie tiez 14.84 (teda aspon oproti hdd pred tym)
mam problem s prenosovou rychlostou... najviac sa mi podarilo dosiahnut 30-40 mb/s
pouzivam filesystem ext4 mam ubuntu 9.10 beta

co mna trapi je vyznacene cervenou farbou:
# /etc/fstab: static file system information.
#
# Use 'blkid -o value -s UUID' to print the universally unique identifier
# for a device; this may be used with UUID= as a more robust way to name
# devices that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
proc            /proc           proc    defaults        0       0
# / was on /dev/sda1 during installation
UUID=11a5cdd5-25fa-4b11-a69b-0f15f4f66a62 /               ext4    errors=remount-ro 0       1
# /home was on /dev/sda5 during installation
UUID=d041d75a-eddc-4c72-b8cf-3f9edfa212c6 /home           ext4    defaults        0       2
# swap was on /dev/sda6 during installation
UUID=1c9f1b04-8096-4bc6-a967-ab99ecef6076 none            swap    sw              0       0
/dev/scd0       /media/cdrom0   udf,iso9660 user,noauto,exec,utf8 0       0

docital som sa toto http://ubuntuforums.org/showthread.php?t=315850
ale kedze to je ssd niesom si isty ako postupovat... viete mi poradit co stym?
a viete mi povedat  ktory filesystem je pre ssd disk najlepsi?
cital som kadeco...ze ext2 je najlepsi,vypnutie journalu atd..
na nejakych developerskych strankach ubuntu som sa zas dozvedel ze ext4 by malo byt vhodne i ked potrebuje este nejake upravy
a je podla vas rozumne si takto vytunint laptop koli ssd disku? alebo je to viez nebezpecne ako uzitocne?

Ako by som si mal nastavit bios vzhladom k mojmu novemu sdd disku?
