I am attempting to set up a Mongoose to run SDD but want a dedicated laptop to do it on - People recommend Windows XP and W7 operating systems - but what is the minimum processor speed, Ram, hard drive capacity - that will run the SDD safely.

There are lots of old laptops around BUT ones that started with XP will be pretty old

Vendors recommend up to 3.5Gh dual core processors - 4G memory etc but is this really neccessary??

I have a Samsung N2190 which has an Intel Atom 1.66Gh hyperthreaded (2 threads) processor, 2038Mb installed usable memory,170Gbfree disk space. Would that run it reliably?

Do you really need an earlier version of Windows to run it? If you do don't forget you can always run the program in compatibility mode on Win10. I can't believe that you really need all that processing power and RAM. 3 x FL1 2 manual + 1 auto
5 x FL2 4 manual + 1 auto
Now Discovery Sport P250 MHEV SE

Apparently the difficulty with using that approach is the continual attempts at updating that W10 imposes - even with a dual boot setup - which is why perceived wisdom is to have a totally dedicated laptop with stable ports and absolutely no internet access. Plenty on the forums about that.
So back to the question.
What is the lowest spec laptop that will run SDD and a mongoose clone or similar. Be great to get peoples actual experience of this.

What version of JLR SDD are you planning to use? My opinion of hardware to drive software is to never use the minimum requirements. I run Version JLR SDD 130 in an XP virtual machine available on the Jaguar forums. The specs are:

Dell D630
SSD
4 GB ram
Intel Core 2 Duo CPU T7250 2 GHz
Win 10 Pro 32 bit

No net when using the virtual environment.
I would spec the recommended hardware for whatever version of SDD you are planning to use.

So far I only have a download for sdd160 - does it need more power?

Thanks for the info on your laptop.

keen to see what others are using - keep it coming - I'm sure others would like to hear peoples experience on this

Like MotionInc I use version 130 on an XP virtual image and run it on an eight year old Acer laptop. Goodness knows what its spec is - it’s just a computer! I also had it running successfully on an ASUS Netbook - remember those? - but its power supply was a bit unreliable and it would suddenly go dead without warning so a bit risky for SDD use.
