How I'm understand rosetta produce a lot of write disk activity and this not very good for ssd. How I can reduce this activity or configure rosetta to use not system disk?

The BOINC Manager allows you to define the location of the data directory when you install. So you could tell it to store all data on a specific drive. I don't recall the steps to change it later but it can be done.

Number Crunching board would be a great place to get more eyes on your question so I'm going to move your post there.

You appear to have a Windows 7 machine. According to this thread at the BOINC website your only option is to uninstall BOINC, move the data directory to the correct location and then reinstall BOINC.

Read this article on SSD life (and the ones leading up to it).

Unless Rosetta's disk writes are truly prodigious, you are unlikely to run into problems with cell wear. All but one or two of the SSDs under test made it past 600 TB of writes, and I think those losers had controller board problems, not cell wear.

Assume 100GB of writes per day, every day -- that's 6000 days or about 16.44 years before the SSD wears out.

I came to the same conclusion - Rosetta's writes are relatively small so the wear levelling takes care of it and you SSD will almost certainly be replaced way before this becomes a problem.

I moved my Data folder to my 1TB disk because of ATLAS which uses a LOT of disk. I did it because of space tho, not writes. Before ATLAS, I had WCG, Rosetta, and GPUGRID running on my SSD.
