Obviously not now.
Don't forget about solid state hard drives (SSDs). Currently Solid State Drives speed up typical database applications by about 30 times. And that's without stripping out all the old caching overhead code databases used for handling the order of magnitude speed differences between RAM and hard drives. Large Storage Area Network Vendors like EMC are looking to SSD Drives to eliminate IO bottlenecks in corporate applications where large datawarehouses reach 20Tb very quickly. And look for capacity to continue to double about every 18 months driving the price down very quickly. And due to higher reliability and lower energy costs to run it won't be too long before hard drive join the ranks of 8-track tape players, record players and 5 1/4" diskettes. http://searchstorage.techtarget.com/sDefinition/0,,sid5_gci1300939,00.html# http://www.storagesearch.com/ssd-fastest.html ------------------------------------------- agi Archives: http://www.listbox.com/member/archive/303/=now RSS Feed: http://www.listbox.com/member/archive/rss/303/ Modify Your Subscription: http://www.listbox.com/member/?member_id=8660244&id_secret=101455710-f059c4 Powered by Listbox: http://www.listbox.com
