re: Quick Guide To Flash Storage Latency Wars
Great summary describing latency in storage. It would be good to have a table comparing latencies of HDDs, SSDs, PCIe and flash memory DIMMs.

Of course, this all stands to change over the next several years as SSDs gradually become obsolete (except, possibly, in hybrid setups) under Moore's Law. http://www.enterpriseefficienc...

re: Quick Guide To Flash Storage Latency Wars
I heard an enlightening cost comparison the other day by Ari Zilka, CTO at Hortonworks. 1Terabyte of RAM = $70,000; 1TB of Flash = $8,000 to $20,000, depending on quality/discounts; 1 TB of hard drive = $60 to $100 depending on quality/performance. Maybe somebody would quibble with the exact figures, but it's clear there is a cost to real-time performance.

Any review on Tape storage,as i don't think it going away any time soon, as it is still the most cost-effective and simplest way to archive huge amounts of data.
