People are becoming more interested in SSDs but there&#39;s still a lot of wariness about them and of course the whole money issue of being able to buy them. I&#39;m also not surprised (given the general readership demographics of this blog) by the number of people who&#39;ve analyzed their IOPS requirements and concluded that they don&#39;t need SSDs to accomplish that.<\/font>\n<\/p>\n<p>\n<font face=\"verdana,geneva\" size=\"2\">&nbsp;<img decoding=\"async\" src=\"https:\/\/www.sqlskills.com\/blogs\/paul\/wp-content\/uploads\/2010\/7\/usessds.jpg\" alt=\"\" width=\"574\" height=\"391\" \/><\/font>\n<\/p>\n<p>\n<font face=\"verdana,geneva\" size=\"2\">The &quot;other&quot; answers were (verbatim):<\/font>\n<\/p>\n<ul>\n<li>\n<div>\n\t<font face=\"verdana,geneva\" size=\"2\">3 x &#39;not in the budget&#39;<\/font>\n\t<\/div>\n<\/li>\n<li>\n<div>\n\t<font face=\"verdana,geneva\" size=\"2\">1 x &#39;I plan to buy expensive drives and throw them at you, paul! love, conor&#39;<\/font>\n\t<\/div>\n<\/li>\n<li>\n<div>\n\t<font face=\"verdana,geneva\" size=\"2\">1 x &#39;I&#39;m going to do the same thing Conor will do.

One number I&#39;d be interested in drilling deeper into is answer #3 &#8211; are people putting\/planning to put tempdb on SSDs because that&#39;s what they&#39;ve heard is the best thing to do, or because tempdb truly is the largest I\/O bottleneck that can benefit the most from SSDs? That&#39;s a set of experiments I&#39;d like to try out with my Fusion-io drives.<\/font>\n<\/p>\n<p>\n<font face=\"verdana,geneva\" size=\"2\">The final &quot;other&quot; answer is also interesting &#8211; I was talking to a couple of folks from EMC in Ireland about the V-MAX when we were there earlier this month. Very cool idea to migrate data up and down a set of devices with varying latencies (at the block level, not the file level) &#8211; I&#39;d like to see more on how the technology copes with one-off operations like consistency checks or backups &#8211; do those IOs affect which layer a block resides in?<\/font>\n<\/p>\n<p>\n<font face=\"verdana,geneva\" size=\"2\">Anyway, hope you find these results interesting.<\/font>\n<\/p>\n<p>\n<font face=\"verdana,geneva\" size=\"2\">Thanks to all those who responded!<\/font><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Back at the start of July I kicked off a survey around your plans for SSDs (see here) and now I present the results to you.
