Some people are worried about the limited write capabilities of SSD's vs Disc Drives.
I'm not one of those people, if my page file is getting used I want it to be on my fasted drive.
I'm going to debunk that... I get it by the problem regularly.
( I will probably get called tonight due to it... )
Well I see it regularly in a twisted way... Some of the equipments I work with uses Compact Flash as Hard Disk.
Since the Compact Flashes are using a tech similar to what can be found in SSD, and since one of my customer ( a French Telco Operator with a big red Logo ) is dumb.
Spamming scripts all over the network to make print on routers when they could use SNMP to get the same answer... at regular interval... some every 5 minutes others every hours...
Basically the spamming forces various log files to cycle really fast... This leads to bits being changed several times a day...
And I'm not even considering the system log file... this one is rotating so fast [ without the help of the scripts ] due to the inability of the operator to manage it's network the right way. ( LDP neighbor going up and down, TACACS server taking too long to answer, BGP Peers being wonky... you name it, they have it... They usually detect DDOS on one of their customer after the fact, not when it happens )
And with that kind of usage, it takes several years ( between 3 and 5 ) before we start to encounter write errors.
Reformat the Compact Flash and it works fine ( it might be missing a few bytes from it's original size though )
Now SSD are really really more evolved than a Compact Flash, there's Trimming, there's how Windows uses it's swap file, there's how the SATA interface works and how the SSD Controller works...
My Swap file is on the SSD. I consider that I'll have to replace my 9 Year Old PC before I see the first eventual failing bit on my SSD Drives.
