1. Would you recommend the Intel or the Crucial?
2. Since i'm dealing with a bunch of relatively small files, random IO will be important for me. (please correct me if i'm wrong). It seems the Intel will be more suited for this job? Please confirm / deny.
Yes, generally Intel is better for random I/O, although less so with the 510 series.
3. The Crucial 128gb SSD is slower than the 256gb? If so, by how much?
About 1/2 for write speed.
4. And finally, price. When do you guys think these guys are going to drop in price? Should I wait? If so, how long?
The Intel SSD 510 is out, I'd go with two of those, they will work nicely (6 Gbps SSD) with your 6Gbps controller
