I can understand your frustration, but you might want to think twice about returning the RunCore drive.
There aren't many SSDs available for the Macbook Air and the RunCore competitors aren't any where near as fast as the RunCore drives. You can check the benchmarks yourself to confirm it.
No matter what trouble you have with them. They're worth it in the end.
While I applaud RunCore for being an innovative new small business that produces products you either can't seem to find anywhere else or perform better than others, I'll point out this is a classic MAC vs PC situation.
At the risk of putting forth two huge stereotypes (but which from my experience are often true), PC folks tend to be tinkerers that are attracted to large feature sets and fast specs, while long time MAC folks are more interested in trouble free productivity and are not too concerned with whats under the hood or how many features something has. I realize this can be very different for recent switchers (in either direction) and not all folks fit into these stereotypes.
Runcore products seem to appear sporadicly in small batches, each batch differing somewhat, with most drives working but each batch having new and interesting problems. Many months after release there are still no decent instructions. Accessories still seem to be of very low quality (which might make some think about the quality of the product itself). Support seems to be from people that care but the systems and procedures in place and the staff quantity make for a pretty poor support experience. So the SOLE things on the positive side are some speed (and in the RevA case) capacity.
Do you really think the Runcore Speed over the stock SSD speed is going to recoup the productivity folks lost with the issues they've had over the life of the drive? And what if the failure rates on these new products are higher? And is Runcore going to be there for you a year or two from now if you have a failure? You have to think about all those things. Maybe these new and unproven products are going to be fantastic and maybe in a year or two RunCore's success will be such they've fixed all their issues and their financial situation will allow them to offer great support. I just don't have to worry about these things with an Apple product.
So for those that have had a trouble free Runcore experience, and enjoy the extra speed over the life of the product, I think thats great. But realize not everyones priorities are the same and a RunCore drive might not be everyone's best choice.
