Are there any utilities that will tell you the health of your SSD drive?
MacBook Air, OS X Mountain Lion (10.8.2), Mid 2012
To my knowledge - there is none.
If you're worried about the life of your SSD.
See image below. that is the expected life span of a SSD if you do 10GB a day.
That's pretty cool. I don't understand the chart. *Less* p/e cycles means shorter life? What's a p/e cycle?
P/E cycle means program erase - that means full install to 100GB then full format.
So, if you have a 100GB Flash Drive and you do 10GB of writes per day - your flash storage will last 8000 years.
Now, I have a Macbook Air - we fall under the 3K section - meaning we can format and erase our flash storage 3000 times before it starts to degrade in performance.
I have several Macbooks. All of them have SSD installed and they're all 3K with the exception of my 2011 Macbook Pro which has a Kingston Hyper X installed and that one has a 5K Nand which gives me a 5000 Program/Erase cycles.
Do you follow so far?
To be conservative - let's just say your SSD should last you 10 years instead of the 8,000 + years in the chart above.
Have a look at the link below regarding P/E on a Samsung SSD by AnandTech.

Ah I see. The top p/e cycles on that chart is what the drive is rated for. How do you determine what an ssd is rated for? (I take it 30k p/ drives are enterprise/server high end drives)
Consumer SSD in the norm comes with a 3K nand. the more expensive ones like the the Intel 520 and Kingston Hyper X uses the 5K Nand. The Kingston Hyper X 3K uses the 3K Nand and is much cheaper than the normal Hyper X.
The one's uses by Apple - if your flash storage is the TS128E or C = Toshiba that uses a 3K Nand and the SM256E = Samsung uses the 3K Nand. The SM512E = Samsung uses the 5K nand.

I advise you to check out DriveDx: http://binaryfruit.com/drivedx . It shows SSD Lifetime Left indicator, overall health rating, important health indicators and many other useful information about SSD. With clean and user-friendly Mac-style interface. (HDDs are supported too)
Fantastic! This is exactly what I was looking for!
Yeah, but for heavy users this can be a problematic area. I destroyed an ssd in 8 months working on 3d animation.
If you're a light user, a few emails, a hand full of documents and a couple of pictures a day just don't worry about it. If you use the ssd a lot more then move all the live data to an external drive.
Just my two penneth.
SSD Health monitor?
