The SSD fever seems to keep rising and rightly so. I had done some crude GPFS performance testing with the SSD enabled IBM Blades against the HDD and the outcome was obvious - higher performance. Can share the result if someone is interested. Well I had to force an hybrid storage setup for it , but i am glad that the mix n mach is available with the new offerings. That is more "Smarter" &amp; pragmatic way - it will keep the cost under control &amp; will enable different sizes for different people (customers) - enable SMB's. Thanks Tony for the timely update.What most data centers ( and eventually data clouds) are going to see in near future is a hybrid storage - SATA solid state drive intermixed with other conventional SATA and SAS drives. What will follow is the smart usage of the two by the application stack above it.<div>&nbsp;</div> CheersSandeep.

Tony, As always great update!I fully agree with Sandeep's remark on the hybrid storage to be viewed on the near future. Adding to his remark, lets not forget that the cost of the SSDs will go down. Maybe not dramatically but I am thinking that in the next 3 to 4 years its price will be near to the traditional spinning disks.What will happen then? only the market can tell.<div>&nbsp;</div> Regards!<div>&nbsp;</div> Carlos

I believe the nature of hybrid will stay for a time. Could be in next 5 years SSD may eat up HDD (like what USB flash drives have done to Floppy and lil bit of CD). But then there will possibly be newer storage like "Racetrack Memory" which might make sure that storage with hybrid characteristics will continue. Now with HDD and SSD .. in future with SSD and Racetrack Memory ( or similar)...<div>&nbsp;</div> Racetrack Memoryhttp://www.almaden.ibm.com/spinaps/research/sd/?racetrack<div>&nbsp;</div> LatersSandeep

Sandeep, can you please share the results, I am very interested but can't find a way to contact you directly. <div>&nbsp;</div> Thanks!
