The 256GB capacity market in the US isn't nearly as saturated as the 128GB arena. If you are looking for a large capacity SSD you have a few options, the Intel 160GB drive that currently sells for 619, the G.Skill Falcon 256GB at 589 and the Corsair P256 at 659 (all Newegg prices at the time of writing). These drives represent different chipsets and are the best bang for the buck in their categories. Even now I have mixed feelings about the Corsair P256. On one hand the performance is very good but lags behind the others in some areas. The overall cost is also quite high, but when looking at the cost per gigabyte of storage the number is much lower than the Intel drives.
The part that I have yet to talk about is longevity. I am still using a set of Samsung SSDs in RAID 0 in one of my computers and have yet to have a problem with the array. Samsung does a very good job testing and perfecting their solid state products before their launch and I have yet to see a page dedicated to firmware updates like we are seeing from the Indilinx drives. Out of the ten or so Indilinx drives that have been tested in this lab, two have failed; one with a month's worth of work on it. Nothing decreases confidence like having a drive fail that is being used for critical tasks. That said, I have full confidence in the Corsair P256 and its ability to not flake out when I am depending on it.
When it comes to real world use I doubt that a consumer would ever tell the difference between the Intel, Indilinx and Corsair drives other than the capacity differences. Testing shows that the Intel controller is still the best product for server and workstation loads and in some cases by a large margin, but Corsair isn't positioning the P256 to play in that arena. For the user it is really going to come down to capacity; is 160GB enough or is 256GB the magic number? Personally I keep a lot of data on my notebook and would choose higher capacity with nearly identical performance. The cost per gigabyte would dictate my buying decision. That stated, Dollar for Dollar the Corsair P256 would be in my notebook.
