64 Bit Support Added to Diskeeper Professional Edition

by Helpdesk 23. December 2005 20:20
Due to the demand we have seen for 64 bit support in our advanced editions, we have now added 64 bit support to Diskeeper Professional Edition. Currently all of our editions (with the exception of Diskeeper Home) support 64 bit computing. Enjoy the extra 32 bits! -Paul

Diskeeper 10.0 is out!

by Helpdesk 6. December 2005 17:44
This is the best version we've ever done by a longshot. Almost everything in Diskeeper 10 has been improved. The first thing users will notice is an improved user interface which is easier to use and provides even more robust reports on disk health, real-time performance and fragmentation statistics. In Diskeeper 10, we're also announcing I-FAAST (Intelligent File Access Acceleration Sequencing Technology), the first successful implementation of Disk Performance Calibration technology. I-FAAST will improve file access times for frequently used files by an average of 10-20% (but sometimes by as much as 80%). Keep in mind this boost is in addition to defragmenting files! Diskeeper 10 really has been designed for today's enrivonment of spiraling storage device capacity. Diskeeper handles bigger drives and bigger files - faster than ever before. Diskeeper 10 also more thoroughly defragments free space and works better in low free space environments. Users will also find that we've made Diskeeper 10 even less intrusive. In version 10 we have improved I/O Smart, which allows Diskeeper to defragment in the "spaces" between normal disk I/O requests. -Paul

Independent performance testing on fragmentation?

by Helpdesk 9. November 2005 02:47
Once and a while I'm asked for independent studies on the performance effects of disk fragmentation. There are some excellent studies out there. Diskeeper Corporation recently sponsored a paper done by Windows IT Pro. Their writer, Joe Kinsella, actually developed his own test tools in order to do a very thorough fragmentation performance study: http://www.windowsitpro.com/whitepapers/index.cfm?fuseaction=showwp&wpid=4D2B047D-E1F8-4F20-A74DB68E7521E730&code= Besides the recent study we sponsored, there are a bunch of other independent studies in existence. A quick Google search yields a Harvard University study on UNIX: http://www.eecs.harvard.edu/~keith/research/tr94.html I was unable to find a university study on Windows. I imagine Universities are probably less interested in studying the effects of fragmentation on FAT and NTFS, because it's generally considered common knowledge that file fragmentation hurts their performance. Once in a while a media source does in-depth fragmentation testing as part of a review, such as this PC Mag article: http://www.pcmag.com/article2/0,1895,1591466,00.asp The non-profit organization National Software Test Lab (NSTL) has also done performance tests on fragmentation: http://www.softwareshelf.com/HTML/products/prod_materials/5/NSTLXP_mddvdk.pdf - Paul

Server Virtualization Weakens Hard Drives?

by Helpdesk 27. October 2005 02:43
Server virtualization is expected to be one of the more disruptive technologies on the horizon. For those that don't know, server virtualization refers to running multiple instances of server OS'es on a single hardware platform. For instance a company could use server virtualization software, such as MS Virtual Server 2005 or VMware, to run virtual instances of both their file and database servers on a single hardware platform. Why would you do this? So you can better match your service needs to the available hardware, possibly reducing the number of servers you employ.
