Hi everyone. I've just built a new system with a 250gb m.2 960 evo as the os drive which will only have the os and a few programs so space shouldn't be an issue.

I was wondering performance wise (Does it benefit much) if I leave the appdata folder on the ssd or should I move it to a hard drive.

I see its was recommended in the past to move it due to the limited writes of the old ssds but doesn't seem to be much an issue with todays ssds.

Performance-wise, you'll benefit from (almost) anything being on the SSD, subject to appropriate precautions, of course.

The 250GB variant has a 3 year / 100TBW (TB Written) warranty

Which, in practice is about 91GB(written) per day, during the warranty period.
Realistically, the writes of an "appdata" folder really isn;t likely to be the difference of being less than 100TBW vs more than 100TBW in 3 years for most people. If you're writing anywhere remotely close to those kinds of numbers daily, you need a whole different class of drive.

Realistically, for most users, other aspects of a drive would fail LOOOONNNNGGG...

I'd hazard a guess that most "average" users would struggle to exceed 2.5TBW annually - for arguments sake, lets double that to 5TBW.

That's 20years (long past obsolescence) of use before it's realistic to expect the "writes" aspect to be the cause of failure in that SSD.

Thanks for the reply.

I shall leave the appdata folder to take advantage of the SSD. Why get an SSD if you're never going to take advantage of the speed.

I should of just looked at my old computers SSD which also had the appdata folder still on it. It's a Samsung 830 pro 256GB that's almost 5 years old now and it only has 7.013TB total writes and 8,970 hours (Mostly only gets used on the weekends).

So as you said, for my usage it will be obsolete before I wear it out.

Now I can finish Windows installation and try out the new machine.
