There's an interesting article on state-of-the-art setup with Mtron Solid State Drives at http://www.nextlevelhardware.com/storage/battleship/ The concise version is that Mtron flash drives puts all traditional harddrives to shame and seems especially well suited for applications that performs a lot of seeks. No surprise there, but read the article for some eye-opening numbers.
At The State and University Library in Denmark we've experimented with two Samsung SSDs vs. two 15.000 RPM traditional harddisks in RAID setup with our current Lucene index at about 30GB and logged queries from our users. For searches we can confirm that the SSDs are substantially faster, especially when the available amount of RAM for caching relative to the index size is small. A teaser-graph can be viewed at http://wiki.statsbiblioteket.dk/summa/Hardware Our test should not be seen as authoritative or even even representative for Lucene on SSDs in general, but it seems clear to us that users of Lucene-systems ought to look into SSDs if they haven't already done so. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
