I have just build a new computer and I acquired a SSD(64gb) for faster read/write performance. I also have a much larger SATA drive. I was wondering if putting the operating system on one or the other will make a performance difference with a program I am running that is moderately heavy in reading and writing (a number of small files(~15mb) that add up to about 4gb). The files will be kept on the SSD, but I did not know if it would also be better to have the OS on the SSD (linux) as well. Thanks for any input.

I purchased an SSD solely for my Boot OS. That's what you want to be the fastest. – Fosco Jul 15 '10 at 17:46

It's probably best to put both the OS and your program on the SSD. An SSD is much, much quicker than a conventional disk drive.

I think this question may be more suited to superuser: http://superuser.com/

For the program itself I don't think it is that important where the OS itself is. It is more important where the swap space is, perhaps. The running parts of OS are in RAM anyway.

And then, you would want to put swap space on SSD, obviously.

Thanks! That makes a good deal of sense. – Anonymous Jul 15 '10 at 17:53

I have a SSD drive. It's very, very fast.

I would suggest using the OS as SSD as well so you do not have to wait.

Pros: - If you put your OS as SSD, you will have much faster boot-time, compile times.

Cons: - You may need to use a 2nd drive to off-load large files when not needed.
