The trade offs with SSDs are a little harsh compared to HDDs, where size does not impact performance to a large degree only the physical location of the data.  The price per gigabyte tends to be a little higher than larger models but again is relatively close.  With an SSD you not only take a noticeable hit to performance with the smaller models you also pay a big premium on the price per gigabyte.  That said, some people simply cannot afford $300+ for an SSD over 200GB. 

For those who want SSD performance for a reasonable price of admission, the 128GB OCZ Octane is worthy of consideration.  There have been no reports of drive failure but at the same time The Tech Report could only find 10 user reviews so it is possible that the sample size is too small to make a definitive conclusion.  If you don’t draw that conclusion the Octane becomes a little less attractive as competitor’s drives tend to be cheaper to buy, even if you lose 8GB of space.  Check out the full review before you go shopping for a small SSD.

"We were impressed by OCZ’s Indilinx-powered Octane SSD when we reviewed the 512GB version last year. Now, we have the 128GB model in-house to see if the Octane’s appeal extends to the sweet spot."
