Failing SSD after just two months?

I purchased my 2012 MBA in November. Today I downloaded and ran SMART Utility, and it informed me that my SSD's SMART status was "failing", after only two months of use (I'm currently at 45 battery cycles).

Here are some screenshots of SMART Utility: http://imgur.com/a/PbbuW
What intrigued me the most was that although the program said that my disk is failing, none of the other tests seem to bring up any errors (zero bad block count; zero uncorrectable errors, normal temperature, etc...). Also, there hasn't been any noticeable difference in speed from when I first got it; I still can boot in under 12 seconds, and I still get read and write speeds around ~500 MB/s.

After reading about it online, I discovered that this means that my SSD doesn't have long to live , so I immediately backed up my data. Anyway, I have a few things to ask:

1: Are SMART tests always reliable? From the additional information given, it doesn't appear that my disk is damaged.

2: If my SSD ends up failing, is this covered by the warranty?

3: If so, can I have it replaced straight away or do I have to wait for the SSD to actually fail before bringing it in to a store?

Thanks in advance!

SMART Utility is usually quite good as it uses the standard smartctl utility as its backend. However it is possible that it's misinterpreting the SMART results from the Toshiba SSD. After all, SSDs will have different SMART attributes to a traditional hard drive.

If the SSD fails, it will be covered by the Apple warranty.

However if all you can provide to the technician is the output of SMART Utility, then it may not warrant a replacement. Apple has their own internal diagnostics for components such as SSDs and if it passes these, then chances are it won't be replaced. You could still call Apple and raise the issue with them, they should note it and create a case / reference number for it should you need to refer back to it later.

At this stage though, I don't think you have much to worry about. If anything else begins to appear though, then you may wish to investigate it further. Of course as always take a backup, as is a good practise with even perfectly healthy drives.

Generally, if they are going to fail, they do so sooner than that but two months is not unheard of. As stated elsewhere, use your warranty.

It will be covered under warranty if anything goes wrong. You said that the SSD is performing OK but diagnostics are showing warning? I'd just keep using it. You have 10 months left of warranty.

Definitely get into a habit of backing up your data! I never done it until after my MacBook completely died on me. Lost all my music, photos, documents and videos I had accumulated over the 4 years of owning the machine. I have 2x256GB SSD's that I back up to. Anytime I add or change a file I highlight it red so I can keep myself right. Copy it over to the 1st SSD which is always up to date. Every couple weeks or so I plug in the second SSD and clone the 1st onto it.
