These are EXACTLY the devices I was talking about. If anyone's ever used one of these I'd love to know.

For a while I was considering buying a Sanho Hyperdrive enclosure and put a 1 TB drive in it, am waiting for them to implement USB 3 and recognition for UHS1.

Then no need to carry any computer!

Nice. Part of the trip I'm camping with Bedouins. Not sure they have wi-fi. :)

If you can find WiFi Hotspots, you can also use an Eye-fi 8gb X2 Pro card, and upload your pics wherever you are.... ( slow, but it works..) .

I'd take a large, tough, USB drive (like the LaCie Rugged 1TB drive) and use other peoples' computers (eg internet cafes or hotels) to copy from the cards to the drive.

Saying that, I'd find it hard to not take my laptop as well.

Like you I've carried the 15" MBP and 13" MBP and don't find either THAT light. Since you're a Mac person, there's another thread here where people compare MB Air vs. iPad for image review travelling light. Next trip I'm probably going to buy a bunch of $16/8GB SD cards and just use my daughter's iPad with an SD adapter to review images.

Anything with Flash (SSD) memory is my advice.

Considered the Netbook route. However, I bought a 10" HP for a my for a school a couple years ago and it was a piece of garbage, at least I thought (sorry if any of you work for HP). Not very durable. Not to mention that I'm a Mac guy and to go PC at this point would be a pain. The falling price of cards does make the "card only" route tempting. I tend not to buy super big cards due to fear of card failure (I'd rather lose 250 pictures than 500 or 1,000 in the event of a card failure). Leaving things on a card might also keep me from catching things like dust on a sensor that could otherwise be removed with a blower. Good points though. If worsts comes to worst I could always use my son's 13" MacBook Pro.

mm Best option, still a mini notebook with a 500Gb harddisk ( lika a Asus EEE PC , or alike with a 10"" lcd screen) those are smaller and lighter than most portable devices with a comparable capacity, and give you an option to already delete all the shots you do not want, since they run VIEWNX2 which is free.....

In my opinion those portabel storeage devices are a bit of history now with the introduction of those small cheap netbooks...

the best You can buy is colorspace udma but it's quite pricey - $300-$400 range, and in current days I don't see (neither the company, as the product hasn't been updated since it release couple years ago) a need for such a device - You can easily get a cheaper small netbook like acer aspire or hp mini not to mention the price of single sd or cf cards (especially sd cards are so cheap right now than for $400 You can get 256GB (i.e. lexar 128cards at BH - $187.95/piece) - that will give You app 16640 RAW images on d90. as for the weight factor... well, two sd cards are much less than even the smaller digital storage disk.

I did a fairly extensive search and found nothing related to this. I'm going on a 12-day trip to Israel and Jordan next year and am starting to plan. I have about 14GB of cards, but I don't think that's going to be enough (shooting a D90 in RAW yields about 260 images per 4GB card). I have taken my 15" MacBook Pro with me in the past on trips like this and uploaded every night, but I think I'd like to try and travel a little lighter this time around. (If you can call a body, 3 lenses, a tripod, and various filters "lighter")
Does anyone have any experience with portable storage drives? I'd post a link to some but I'm sure it will get bounced. I see they range from a few hundred to a couple of thousand dollars. I wouldn't need to be storing video, if that matters. Seems to me that being able to store 300-500GB in a device the size of a pack of cigarettes then offloading the images onto my laptop when I got home would be pretty good.
