I have 3 Sonata Trading Computers that I have bought from Traders World over the years, each supporting 4 monitors. They are only used for trading. I run TradeStation on them with very complex proprietary algorithms that need extensive computing power. The Sonatas are both amazingly quiet and fast and I am totally satisfied with them. I have had no mechanical problems with them. I, after buying my first Sonata Trading Computer, bought a “trading computer” from another vendor, and to my constant regret it was unbearably noisy, and mechanically a hard drive went out after less than a year of use. I did not even bother to repair it – I just bought a second Sonata, and then a third one a few months later. I will not even bother to check out any other source for trading computers after 3 years of experience now with Sonatas.
