Recently I replaced two Intel SSD X25-M 80 Gb drives, configured in RAID1. 3,7 years ago these drives were installed on a small SME8 server, about 10 users in a small office.
Remember the discussions about using hardware with known wear leveling limitations, with a journaling file system (ext3 without modifications) and an OS (SME8b6) that did not properly support TRIM at that time.
So I installed Intell SSD toolbox software on a windows machine and hooked up the SSD to satisfy my curiosity
Here are the stats, FYI.

I do not have or use SSD's, but I am a quick learner, so what is your point, is this good or bad in your experience ?
Out of interest, what did you replace them with, & where/how is your server being used ?
Just to satisfy my curiosity also !

seems good, but indeed i'd satisfy my curiosity, please add your thoughts eastend99

please add your thoughts eastend99
I replaced the disks because the server ran out of disks space. I replaced the 80 GB SSD's with 240Gb Samsung pro models.
I also wanted to know the level wearing numbers.
My conclusions:
Small servers low data volumes: always use SSD's, buy the versions for heavy use just to be sure. Fast and reliable.
About once in two years, I always had to deal with disks problems on spinning disks.
The estimated lifetime shows it should live for about 25-30 years. The best practice is replace 24/7 spinning disks within three years. I will change that to "disconnect one of the SSD's in the default raid 1 array and run the SSD diag tool to check the SSD's condition."
I do not expect the SSD to live 25-30 years as the calculated expected lifetime suggests. But 5-10 years seems plausible.
The technical lifetime of the device is no longer be the primary reason to change it, in 5 to 10 years the need for more storage volumes will drive the change.

I think all info is good, an this info bring GREAT news... for small environments.
But it's for only 10 users, if they use it just as file server, the wearing level can be unreal.
Maybe with a database on SME the wearing level can be much worst.
There are any database being used on this client ?
Anyways I like this:

Thank you for the info!
