MacBook Air SSD crash & burn...4 days out of warranty

It is recommended to have atleast 20% of free space in your drive. As you already have 25% but, I would suggest to clean some useless applications, empty trash and if possible get some drive cleaning app for your Mac. Hope it will work.

hope the genius light the way

That free space recommendation applies more to Samsung than others as they start to become less I/O rate stable as free space becomes less than 25% which results in noticeable beach ball delays doing things, even mundane as switching app windows. As general rule with non afflicted storage is to critically clean if free space declines to less than the greater of 10GB or 5% of your drive's capacity.

As a side note - from a performance standpoint, in real world - 2nd gen (current) as well as 1st Gen provide consistent performance from 0% to 99.9% used. Sandforce is also tops for performance general except with highly incompressible where performance peaks near 300MB/s vs over 500MB/s with typical data.


OS X needs free space though and at less 1GB free, quickly dives into painful to use.

Good luck - hopefully Apple will help out. If not, these drives are easy to DIY replace.

Hmmm....I was surprised to see that there is now a prevalent opinion now on tech forums that Sandforce controllers, particularly first gen, are prone to causing the drive to freeze (in some sort of suspended state or something like that...) amd that firmware updates have never adequately addressed the problem.... 2-3 years ago all you would hear is that you want a Sandforce controller.

Depends on the drive brand - and unfortunately, the brand the sold the most Sandforce based drives also was effective in giving SF a black eye at one point. There were definitely challenges in general at various stages - but the last update for 1st gen SF controllers is about a year or 18 months ago and zero issue with all Apple sleep/wake/power modes - including change 10.7.x introduced - since a few updates prior to that final one.

Makes sense. I think you're talking about OCZ.
Pretty much all of the problems I saw mention of were with Windows.

Do you guys happen to know who made the SSDs in your 'books?
There seems to be a lot of info out there suggesting 1st gen Sandforce controllers are dogs.

1st sandforce controllers had some compatibility issues, majority of the issues were at SSD makers end which was unfortunately targetted at sandforce as the SSD maker popularity was huge compared to the controller. However, sandforce came out very strong in their second gen controller & are ruling the controller world. The earlier wrong perception trigerred during the 1st gen controller is unbelievably still persistent!! If you use the recent sandforce based SSDs, your opinion on this will surely change.
