$ 400 is not unrealistic for a used Toughbook, or? Less for my MK1 [/ quote]
From what I have read so far there is a CF 31 MK2 i7 that was a high-end Toughbook which was special ordered by customers. You cannot add USB 3 to a i3, i5 or a i7. The USB 3 controller chip is built on to the motherboard. That is why it was special ordered and can only be done at the factory. If you can actually find one it's going to cost a lot more than $ 400. Check out the link below.http://forum.notebookreview.com/threads ... 0m.813491/
However, the MBR-2TB limit bothers me.
When I install Windows 10, this notebook (MK1 with 8GB RAM) runs slowly.
When I try to install Win7 (included with the MK1), it does not work on the 5TB-HDD.
These are reasons for which I still like to look for a faster full ruggedized notebook or tablet with USB3 and support for HDD with more than 2TB.
I saw on eBay that a CF31 MK5 (with 1024 x 768 touchscreen - 1200cd / m2) has an auction price of ~ $ 468.
Four generations later, and still XGA resolution?
Why? It is clear to me that this is not a multimedia device for hifi, but XGA with a limited viewing angle is little for the age of the notebook. Websites are displayed at 1024x768 today with restrictions.
The question is less than a year old, it was said here:
[quote = "toughasnails"] So you are saying you only want to pay $ 400.00 for this Toughbook? If so you are not going to find one. You are asking for an awful lot for just $ 400.00 [/ quote]
A CF-31 MK3 from a retailer (with a one year legal warranty) currently costs around $ 383. From a private individual who resells it after a few month, about $ 310.
"You cannot add USB 3 to a i3, i5 or a i7"
I never claimed to add USB3 to the base hardware.
I meant a PCIE controller. I now have a PCIE controller for USB3 for the old MK1-CF-31. That's working.
