If you have no issue waiting till Midnight on BF (2 weeks) I am sure at least 1 SSD will be $1 a GB. Personally unless I can buy at that price point I am waiting for the next gen. This year should have some good sales for the simple fact people are buying less. Go look at Neweggs "poll" 50% are buying less so usually they will tempt us harder to make their quarter
Sure it will saturate my SATA2 board but with Vertex you never get the speeds on the box on compressed data so on a SATA3 drive I should get SATA2 capped numbers on compressed data. Most Vertex 2 users I know get 200mb read/170mb write. Which is not bad but I wont upgrade for 2-3 years so I want a drive that gives me full performance
That to me is worth waiting 2-3 months.
