A new white paper covering "NTFS CHKDSK Best Practices and Performance" was posted today at microsoft.com/downloads, covering the CHKDSK improvement in Windows 7 and Windows Server 2008 R2.
This was first highlighted in a blog post by Claus Joergensen in the Filecab blog. Claus mentioned: "Today, Microsoft released a new white paper discussing best practices and guidance for sizing NTFS volumes and some details on CHKDSK execution times on Windows Server 2008 R2. When planning Windows File Server deployments. We are often asked questions such as 'How large can I make my volumes?' or 'How long will it take to repair a volume?'. This white paper helps answer these questions."
Scott M. Johnson also covered the the white paper release on Storage Server blog. Scott said "If you are planning a Windows file server deployment or is looking to upgrade an existing Windows file server deployment to Windows Server 2008 R2, you should consult the white paper. It outlines how with Windows Server 2008 R2, NTFS can scale to easily support 15 TB file systems with 10 million files! Even with hundreds of millions of files the CHKDSK execution times are really fast."
