Moin Leute,

hab mir vor circa einem Jahre ein ThinkPad Edge 13 geholt und mit einer Intel X25-E 32GB bestückt. Performance war großartig. Nun wachse ich immer mehr in Linux rein, speziell auch Gentoo und habe letztens (man optimiert ja das System irgendwie ständig. ;)) festgestellt, dass die SSD Performance nicht zufriedenstellend ist.

Code:
edge alex # hdparm -tT /dev/sda

/dev/sda:
 Timing cached reads:   2686 MB in  2.00 seconds = 1343.92 MB/sec
 Timing buffered disk reads: 454 MB in  3.01 seconds = 151.05 MB/sec


Timing buffered disk reads ( -t ) war damals mal bei um die 270 MB/sec.

Die SSD unterstützt kein TRIM. fstrim usw. fallen also leider flach.

Paar Daten zum System:
Code:
edge alex # uname -a
Linux edge 2.6.39-gentoo-r3 #9 SMP PREEMPT Wed Aug 31 22:41:08 CEST 2011 x86_64 Genuine Intel(R) CPU U7300 @ 1.30GHz GenuineIntel GNU/Linux
Code:
# /etc/fstab: static file system information.

Weiß jemand einen Rat woran das liegen könnt, oder neigt sich die SSD schon dem Ende zu? O.o
