I got 1 for about 110 euros
there's a 512GB one as well for 250 euros
Even with the prices of SSDs dropping like crazy, I'd still rather take a spinning drive for storing large quantities of data. While SSDs make great boot drives and are awesome for quick read speeds, constant writing of data onto them can actually wear them out and deteriorate performance over time. With the price of spinning drives dropping just as quick, I'd much rather pick up a couple of WD Caviar Blacks, or even for maximum performance, a couple of 1TB or 500GB 10 000 RPM Velociraptors with a RAID0 setup.
Regarding the Fusion Drives, if I'm not mistaken they store your software onto the SSD and gradually move it over to the spinning drives over time if it's not being used (or does it start on the spinning drive and micrate to the SSD?), which is all fine and dandy, but even with a 64 bit OS and CS5 with plenty of other software installed onto a 120GB drive, there should still be enough space to store ALL of your software. I don't know why Apple didn't just decide to store all software onto the SSD and then migrate it as the drive was almost filled, my OS/software partition currently only had about 70GB worth of data on it and I don't see it hitting the 160GB limit anytime soon.
