Has anyone installed a high I/O application such as an email server on SSD drives?  Was thinking about doing two SSD's in RAID1.  It would solve my I/O latency issues but I have heard that SSD's wear out quickly in high I/O situations?  Something like each memory location only has X many writes before its done.  Just wandering if anyone has tested it and if newer SSD's are better about this?

Sun were recommending using SSDs for the ZIL in really big ZFS install *years ago* so go for it.

As long as you are using TRIM then you avoid the slowdown that happens once the ssd is full
