Someone just pointed me to this blog post about Windows 8
It looks like Windows 8, at least the server version, is going to get a modern storage stack file, volume management, a file system and some resiliency features. I see the target of what they are doing as the lower end of the small business market with people that today have under 10 TB of data.
This is a big change for Microsoft. As someone who has railed about the poor performance, poor metadata management, poor resiliency and so on of NTFS, this is a small step in the right direction. It, of course, does not solve the home user problems as I quote, "first as a storage system for Windows Server, then as storage for clients, and then ultimately as a boot volume. This is the same approach we have used with new file systems in the past."
Over time, could this change the market for the lower end NAS products as why do have an extra management framework? NTFS should have been replaced at least 5 years ago with something that has some modern features and functions. So it looks like we have another 3 to 4 years from now to have a new file system that runs across the Windows product lines from the home user to the server. Let's see, by that time we should have disk drives supporting bit-patterned media with significantly greater density, SAS channels running at 12 Gbits/sec and PCIe 3.0 running in home PCs.
Microsoft has delivered way below the mark of what is needed -- at least what they have announced. We get Windows 8 in 2012. We got NTFS in 1993, and it lasted for almost 20 years. ReFS is not going to work well 20 years from now.
