I’m putting both my amibroker Executable and my AB database on my SSD. The speed increase is noticeable, but I have a TB SSD, so there is plenty of space. I have a fairly large US equity & mutual fund DB (~9000 tickers) - with the AB files, whole thing is 1.2GB in size. I can’t conceive that every listed security ever in every world market with historical data to start would take more than 10GB? Windows takes far more space, obviously.
Would recommend it. A lot of DRAM is also fun to have, so if you are having speed issues, upgrading size of that might really help. On older builds I went up from 2GB memory to 8GB and it made a ridiculous difference. Now I’m sporting 64GB, but that’s overkill for most applications. (not mine though).
