NTFS is used on millions of mission critical machines, not to sound like a marketing message, and if you got errors every time there was a quick boot/power outage (i.e. these accumulated errors left over and not burned to disk), I can't imagine anyone using NTFS or even Windows. Dunno. I was just reporting the reason supplied by the person responsible. I suspect the errors are small but cumulative, which would allow for corrections as long as the next shutdown was normal. Thus, it may take a lot of fast boot/power outage executions in a row for the error correction to not catch up. Let's put it this way - if you're running IT for Chase Manhattan or Exxon, you're not waiting around for errors, you're switching to a different system if yours can't perform right. The Windows server market wouldn't be growing if there were such basic errors. Sure, you put UPS's up, etc., but the basic file system has to perform flawlessly, or you go to Unix where it does. As for mission critical Windows boxen, I'm mostly familiar with NTFS used in mission critical control systems, where it does not get rebooted very often, now that the 45 day issue is resolved. I'm not sure it's safe to say there are millions of mission critical machines running Windows - there certainly are millions of Windows machines, but most of them are not mission critical. Roughly 20-25 million servers worldwide, Windows servers nosing out Unix servers in revenue in 2005 from 7.6 million servers that shipped. 2 million servers shipped in Q1 2006, Windows has 37% of the revenue. 46,000 sites running SAP (typically many many servers), 2/3 of all new SAP installations (sites) run Windows. I can't tell you how many Windows servers exactly, but sounds like millions, and pretty mission critical. http://www.itjungle.com/two/two030106-story02.html http://www.internetnews.com/stats/article.php/3608666 http://www.sap.com/company/press/press.epx?PressID=4520
