Sorry I don't quite follow you traderharley. You can have both the SSD and the Spinner drive hooked up at the same time. But, I believe, whichever physical drive you BOOT FROM (maybe selectable from your BIOS, I don't know)... then Windows will assign it as the C drive. If you boot from the SSD drive, the SSD drive will be your "C:" drive in Windows. If you boot from your Spinner drive, the Spinner drive will be your "C:" drive in Windows. The other drive will be mounted by Windows as other disks and would be assigned a letter - may be D:, maybe E:, maybe F:, so on... depending on if you have other partitions defined on your SSD. Anyways... I assume that you want a SSD because it is fast, and you want to boot from it. So your SSD will be your C: drive. But all your other software were installed on the Spinner drive, which is anything but C: drive. So you would need to re-install all your software on the SSD. I suppose there are ways to trick Windows to retain those software without re-installing. I am not sure. It may get more messy than it's worth - than re-installing on the new SSD.
I've got them in a couple of my machines.. they are good.. about the same as the X25-M G2s. They don't bench as fast as all the ones with a Sandforce controller, but are accepted as be among the most reliable of brands/models. And those who have tried the really fast ones say there is no perceptible difference in every day operations vs. the ones regarded as "not the fastest". A recent Tom's Hardware article basically said the same thing. Best performance increase usually seen in notebooks. Newegg had similar sale/rebate a couple of weeks ago as well as this one. Perhaps Intel is trying to clear excess inventory and you'll get another shot soon. I bought a couple of extras... after writing them off, the after-tax cost is cheap enough to have spares around. And the 320 is one of the few with 5-year warranty.
