That's expensive, don't know about you but I don't factor in drives to be dead within 3-4 months of installation for my machines. Running swap on an MLC SSD will most definitely kill it in 3-4 months. You expect to get at least 18-36 months out of a drive before it either dies or requires an upgrade.
500GB Sata disks = $150 for good ones, that's $150 every 30 months (2 1/2 years).
A CHEAP OCZ MLC drive is $100 for 40GB, burn one of those every 4 months and you have to buy 8 in the same 2 1/2 years.
That's a $650 operating increase, or an additional $21/mo for a rented server before profit mark up. Why not just use what Linux was designed to use? A regular spinning disk, if you want performance get into Raid 10 with SAS drives. You'll get a significant speed increase at a lower monthly operating cost due to the longevity of the drives, and you can avoid all that pesky restore from backup situation 4 times a year.
Lets face it, a var partition goes and you're gonna have a hard time starting up some services on boot, depending on your setup SSH wont start. So now you're entering the realm of remote hands and eyes fees, and at minimum that's going to be $50/hr with a hefty commit (if you're in a quality datacenter of course).

It's really neat when an OCZ drive fails, it doesn't tick. You just lose all your data. Here today, gone tomorrow.
Just swap drive and restore from backup, no problem ?
