Recently upgrading, I bought the newest MBP 17" specifically because it still had the expresscard slot (thinking having eSATA capability would make it the only pro laptop in the new lineup). I don't need my storage to be portable, I edit at home. Being new to RAID I've been researching and asking questions. I want to get the best setup for my money. People have recommended FW800 but that doesn't help me need to get the most speed possible, I feel eSATA is faster. I also want the redundancy in case a drive crashes. But the MBP only has one expresscard slot. Does this mean my bandwidth is limited to one 300Mb/s channel? i.e. Should I not even consider RAID0 on a MBP since the bottleneck is 300MB/s? Barefeats recommends this adapter saying it's the fastest they tested at only 200MB/s! So what advantage will stripping give? It seems with only one available eSATA channel the MBP doesn't have many options for professional storage (although still faster than FW800). What would people recommend? As for redundancy I don't need constant real time updates like RAID1, I feel a simple daily backup utility is all I need for my library and would rather not introduce needless drives to a RAID setup. My need is for my very rapidly growing library of media files (5DmarkII-- 40Mb/s H.264 & 20+MB RAW files). I use After Effects, FCP, Lightroom, and Photoshop and do high end graphics and video editing. I am not a professional editor, but am a professional shooter, so although I require the professional capabilities I am not interested in getting the best and most expensive setup.
