Thinking Differently About SSDhttp://en.community.dell.com/blogs/insideit/archive/2009/04/24/thinking-differently-about-ssd.aspxWhen I talk to customers about storage challenges and technologies, it is always interesting to get their thoughts on one of the areas that has gotten a lot of attention over the last couple of years: flash or solid state drives (SSD).

My real concern at present is low service life, as writes seem to (so far anyway) have a finite value. Once that hurdle is cleared, who needs moving parts and heat?</p><div style="clear:both;"></div><img src="http://en.community.dell.com/aggbug.aspx?PostID=19474334" width="1" height="1"></description></item><item><title /><link>http://en.community.dell.com/blogs/insideit/archive/2009/04/24/thinking-differently-about-ssd.aspx#19474187</link><pubDate>Fri, 24 Apr 2009 15:29:19 GMT</pubDate><guid isPermaLink="false">e3197daa-ef0d-4a70-8402-29215ff9a0f2:19474187</guid><dc:creator>Carl Culbertson</dc:creator><description><p><span style="font-size:8pt;color:black;font-family:&#39;Arial&#39;,&#39;sans-serif&#39;;">&nbsp;I like this article on how to analyze the advantages of SSD beyond a $/GB comparison.</span></p> <p><span style="font-size:8pt;color:black;font-family:&#39;Arial&#39;,&#39;sans-serif&#39;;">I did some research a few months back on the types of SSD drives out on the market and the underlying&nbsp;technology differences in the memory chips.&nbsp;I found this general&nbsp;WIKI to be very informative of the perforamce differences in the chips and bus&nbsp;through put. </span><span style="font-size:8pt;color:black;font-family:&#39;Arial&#39;,&#39;sans-serif&#39;;"><a href="http://en.wikipedia.org/wiki/Solid-state_drive"><span style="color:#800080;">http://en.wikipedia.org/wiki/Solid-state_drive</span></a>&nbsp;</span></p> <p><span style="font-size:8pt;color:black;font-family:&#39;Arial&#39;,&#39;sans-serif&#39;;">If you want to get down and dirty with the reliability of the chips and the cost differences between SSDs, the conversation&nbsp;&nbsp;about SLC Nand vs MLC Nand would need to take place. This page on Microns website has many documents relating to the differences in the chips as well as several underlying technologies. <a href="http://www.micron.com/products/nand/mlc-slc"><span style="color:#800080;">http://www.micron.com/products/nand/mlc-slc</span></a>&nbsp;</span></p> <p><span style="font-size:8pt;color:black;font-family:&#39;Arial&#39;,&#39;sans-serif&#39;;">This Page has a great approach to presenting the differences in a relatively easy to understand discussion. The Super Talent document referenced on the bottom of this article details the endurance of the two&nbsp;chips, SLC devies having 10x the endurance of MLC is on page 8 o fthe document.&nbsp; <a href="http://www.smxrtos.com/articles/mlcslc.htm"><span style="color:#800080;">http://www.smxrtos.com/articles/mlcslc.htm</span></a></span></p> <p> <p>&nbsp;</p> <p>&nbsp;</p> </p><div style="clear:both;"></div><img src="http://en.community.dell.com/aggbug.aspx?PostID=19474187" width="1" height="1"></description></item></channel></rss>
