Hi list,
on my workstation I've a md raid (mirror) for / on md1. This raid has 2
ssd as members (each corsair GT force 120GB MLC). This disks are ~ 5
years old.
Today I've checked my ssds smart status and I get:

The second ssd has very similar values.
SSD_Life_Left is 0 since ~ 1years ago for each ssd. Today these disks
are working without problems:
# hdparm -tT /dev/md1
/dev/md1:
Timing cached reads: 26322 MB in 2.00 seconds = 13181.10 MB/sec
Timing buffered disk reads: 1048 MB in 3.00 seconds = 349.00 MB/sec
# hdparm -tT /dev/sda
/dev/sda:
Timing cached reads: 26604 MB in 2.00 seconds = 13322.82 MB/sec
Timing buffered disk reads: 1140 MB in 3.00 seconds = 379.87 MB/sec
# hdparm -tT /dev/sdb
/dev/sdb:
Timing cached reads: 26258 MB in 2.00 seconds = 13148.38 MB/sec
Timing buffered disk reads: 1140 MB in 3.00 seconds = 379.70 MB/sec
# dd if=/dev/zero of=file count=2000000

2000000+0 record out
1024000000 byte (1,0 GB) copied, 2,36335 s, 433 MB/s
My ssds are failing?
Thanks in advance.
