How durable are DSLR SD card slots? - 1

One of the reasons i'm considering buying an eye fi card is not having to keep taking it out over and over again from my D7100 and wear it down

is that a legit concern? How durable are sd slots in Nikon dslr's?

Really good. I've never had a problem with SD cards in any installation… And I've been using them for years.

I'd doubt you'd have any problems at all as long as you don't put the card in backwards and force it in or drop the camera or beat it up in some other way. In other words, if you care for it properly you'll never have a problem.

Jordan,
That is a good question. I have never heard of anyone ever having had any problems with SD card slot connections over a long period of time. I think the camera companies are probably putting a thicker coat of gold alloy on the SD card slot contacts. I have a 7 year old Nikon DSLR and the single SD card slot has been used by 8 or 9 different SD cards that I own several hundred times so far.
I have read in many reviews that the Wi-Fi SD cards, have very slow transfer speed, so if you are taking a lot of pictures especially in RAW you may be extremely disappointed at the time it takes to transfer your files to your computer. Slower than a turtle.
I think you have nothing to worry about.

Using them for about 10 plus years now with no problems at all. And I remove from camera to download to computer rather than use USB cable provided with my cameras.

I have never had any issues with SD card slots. If you take reasonable care of your equipment, you should not have any problems…

and at least with your D7100, you have a spare slot.

The cameras are designed to take around 150,000 shots, so the SD slots should be capable of handling repeated card use!

One of our cameras is 8 years old, I would guess the SD card has been removed and replaced a thousand times with no problems. I'm sure that a professional photographer would have R&R'd the SD card several thousand times in that time period.
