I have had a computer with an SSD for about a month now I have to say it is just amazing. Fully lives up to the hype. Logos in particular runs like I always thought it ought to run. Indexing when I buy a new book--something I do pretty regularly--used to slow Logos to a crawl. Not, it is virtually unnoticeable. It makes the experience of buying and indexing books so much better I have thought that Faithlife might do well to give SSDs away so as to encourage people to buy new books!
It is like the difference between dial up (remember the day) and FAST broadband. If you are not running Logos on an SSD, you might consider doing so soon.
