For editing or for back-up? If for rendering, editing, etc. of multiple streams of compressed or uncompressed HD then I'd go with e-sata raid 3 or 5 with SSD drives. I like G-Tech, Cal-Digit and Sonnet. Buffalo has a drive that is both USB 3 and Thunderbolt. I have bought enclosures and built my own as well -- which is always cheaper. Be glad you have e-sata. It is more universal and cheaper than Thunderbolt. If you use raided SSDs it will fly.
