Depends on the camera, and file settings. But of course! D800 shooting at 14bit uncompressed RAW is 74.4 MB. D500 shooting at 14bit uncompressed RAW is 25.0 MB.

For the D800, it gets a bit over 800 shots out of each 64GB card, and 192GB works out to roughly 2,500 shots. That's 10 days @ 250/day...enough capacity yet? Basic arithmetic will tell you that you cannot get thousands of images when shooting at 14 bit uncompressed NEF. Sorry, but since it can be shot & stored, the number of GB for storage for 1,000 shots is simple math. And at ~$1/GB (retail), the estimated acquisition cost is quite straightforward too. This isn't a technology barrier - it's merely cost...and as I said, memory cars are profoundly cheaper today than even but just a few years ago. And frankly, when we dropping $2K for a body or $1K for a lens, why should spending +$100 for having a 1,000 magazine depth (or +$200 for 2K) be such an whinefest? Ditto if one considers including travel & vacation expenses ... and even one's PC too... -hh -- PeterN |

But you won't find such a place at the top of machu picchu that is the point. As of a ~decade ago, the only establishment at the top was the Sanctuary Lodge. There's been attempts to close it, but its reportedly still open: https://www.belmond.com/hotels/south-america/peru/machu-picchu/belmond-sanctuary-lodge/ I was able to find a simple room rate; a mere $650/night (+10% tax) which includes WiFi, but not breakfast. The same room with full board is $1100/night (after the 10% tax) which is why most visitors choose instead to stay elsewhere (down in Aguas Calientes). You might be lucky ... but don't expect the same sort of upload/download speeds you get in large cities. WiFi is technically available, but the level of bandwidth needed for a significant data dump is the risk, and this IMO includes the town of Aguas Calientes. Their only land connection to the outside world is the train line and their relevant communication lines are IMO probably along the same train route. The rail has had semi-regular seasonal breaks in service from spring floods washing out a section, which would likely also take out their communication too, although when this does happen, the tourism is suspended. Even so, when you have 5,000 tourists arriving back at their hotels each evening, the network is going to get crunched. As such, I'd be reluctant to assume that I'd be readily able to data dump from cards at this stop. Sure, one may get lucky, but for planning purposes, I'd assume nothing more optimistic than having the first reasonably reliable backup opportunity (via an Internet Kiosk) probably won't be until returning back to Cuzco... You'll also be suprised to find that there's no mcdonalds at the top of machu picchu. Pragmatically, the trekking groups enter via the Sun Gate and then stay for most of the day (touring the site) before catching a bus for the half hour ride down the switchbacks to Aguas Calientes. The implications here are that one will need to have +1 more day's worth of {power & memory cards} after the days on the trail before getting to a hotel to check in & having the opportunity for a systems 'recover' (be this power and/or data). And since MP is a journey highlight, it can be expected to be a day with a much higher demand for photo taking. -hh |

You did indeed get lucky. Amazon sells the Lexar Professional 128 GB for $275. Yes I know there are cheaper cards, but I have used only the Lexar or Sandisk. I have read too many horror stories about other brands. I will go with the odds. https://www.amazon.com/gp/product/B00OD71AYQ/ref=as_at/?creativeASIN=B00OD71FKU&imprToken=oAiI2JK4L2Uo.pX s32NUfA&slotNum=14&ie=UTF8&linkCode=w61&tag=bpg-cardbuy-20&linkId=45e5111d0158cfbd8da8bd84b9d7c57d&th=1 For the D800, it gets a bit over 800 shots out of each 64GB card, and 192GB works out to roughly 2,500 shots. That's 10 days @ 250/day...enough capacity yet? Capacity sounds about right. When I shoot landscape I shoot at most about ten frames per hour, fifty if I am bracketing, (Since there is a lot of DR in the D800, 1 EV difference is not very meaningful, Therefore, I need five shots to get 2 EV difference.) If I want to do panos, could be significantly more, depending on the scene. Basic arithmetic will tell you that you cannot get thousands of images when shooting at 14 bit uncompressed NEF.

No argument from me, on that. my personal preferences are to use 32 GB cards, as that is usually enough for a days shooting. I figure that if I lose a card, I only lose that day. Remember I have two cards in each of my cameras. YMMV -- PeterN |

My last 'off brand' were some Delkin's in 2012 (was $37 for 16GB = ~$2.30/GB) I used to deal only with B&H and a local store, Koh's. That started when I was pricing a lens, and he was several hundred less than anybody else. When I asked him if it was gray market, he said no, it was used. That lens could have passed for new. Jimmy though is only authorized to sell new Nikon P&S & accessories. He recently retired. Over the last two years I developed a relationship with Hunts. I no deal only with them and B&H. There have been several times when both have advised me not to purchase an item, although it cost them a sale, that would have amounted to several hundred dollars.

Yes, there's always more considerations and elements to consider building into one's contingency plans. The good news is that memory pricing isn't one that still costs an arm & leg. For the D800 the lower speed CF cards are fine. The SD card throughput in the camera is so slow that it almost doesn't matter. However, to avoid confusion I get the higher speed SD cards, because my D500 can use the higher speed. I like the availability of the higher speed, and the cost difference is small, compared to all the other costs involved. I was recently checking the MTBF, and came across this: https://www.amtron.com/cfcard.htm Prices are significantly higher. e.g. 16 GB CF card 299.99. Looking at the specs, I doubt if my photography would ever require those temperature tolerances. -- PeterN |

As the OP implied it's whether you have battery power for taking phosos is what's important. There's multiple points of failure to manage; battery is merely one necessary component of the overall system workflows, as is also the sufficiency of the recording media, getting it safely home from the remote site, etc. WiFi is technically available, You can't use wifi to take photos. True, but it is part of a potential workflow to "get the photos back home". Not the only solution, but merely one option of several. Could also use a microSD attached to the leg of a homing pigeon. and this IMO includes the town of Aguas Calientes. Their only land connection to the outside world is the train line and their relevant communication lines are IMO probably along the same train route.

FYI, same problem also happens on cruise ships. -hh |
