How to check SSD health

Hi

I am wondering whether there are any program to check the SSD health or the number of the write cycles on the macbook air? I am a little bit worried about the ssd on my macbook air since it only has 2 Gb ram and the ssd drive will be used as the virtual memory.

I can't answer your actual question, but I do remember reading about this some time ago when I got my first SSD. The conclusion I came to at the time, was that on the average SSD, you would have to continuously write/overwrite for 10 straight years before the write limits would be reached.

Just use it and do not let this ruin your experience. Problems might arise in YEARS and not a few days!

Be lucky you did not get my MBA:eek:

Tell the SSD to turn its head and cough.:D

Testing the SSD simply adds write/read cycles, why do it? People need to use these devices and enjoy them instead of incessantly worrying about them.
 
I've had my intel G2 SSD for maybe a year or so, I just ran AJA and got between 116-209 mb/sec reads but only 20-46mb/sec writes.

Apparently it doesn't take long for this to be a problem. When I originally got this SSD it was much faster and i thought recently it seemed slower, but I hadn't tested it until today.

So don't be so blase about SSD performance.

At this time, I believe the conclusion is that , at least on a Mac, it's a matter of months till most (not all) SSDs have degraded significantly.

Totally agree. I have a friend who purchased an MBP earlier this year and he simply refuses to run the thing on battery power. For example, he will sit at Starbucks etc. doing absolutely nothing for as long as it takes for a seat near a plug become to available. It's infuriating.

There's a $40 program called Disktester that will recondition an SSD to speed it up. On my Rev B, I was definitely pulling in lower numbers as the SSD aged, but it was still fairly decent after two years and I had no concerns about data failure.
 
there are some things u can do to help ssd last longer,one is to disable mba hdrive[sys prefs energy saver]from sleeping on bat or power,enable noatime,occasionally do erase free space.disable hibernate,
