Added some new stuff to my original thread post, but here it is...
> DirectX 11.1
Not much info on this yet, but this will mostly be a performance enhancer rather than something that adds many big new features (like with Tessellation on DX 11).
According to MS every individual DirectX graphics API is getting some kind of improvement in DX 11.1 - likely performance improvements and tweaks mostly for the mobile GPU's used in tablets, but there will be some improvements for desktops too.
> Storage Spaces
Big feature this. Many people were very annoyed when MS decided to remove Drive Extender feature from Windows Home Server 2011 (which was one of the best things about WHS). Well now it's back and even improved with Win 8, but now it's called Storage Spaces. What this basically lets you do is create a "pool" that contains multiple hard drives but the whole pool is treated as a single disk and appears as a single disk in Windows as well as to software or anything else. It's a bit like RAID but
way more flexible, modern and easier to create. You get the performance from RAID-0, and the option to mirror data that you get with RAID-10. You can mirror data 2 or 3 times. If one disk dies the Storage Space will continue to work as normal and automatically create a new mirror of any data that was lost on the defective drive. You can also add as many new drives to the storage space as you like after it's been created. SSD's and HDD's can be used together (in different sizes too), as well as different connections like USB, SATA, or SAS, all in single Storage Space. Theres also no limitation to the amount of drives you can add, so in theory you can add a ton of SSD's and get insane performance.
Theres a lot more to Storage Spaces so check out the
MS blog post.
...Storage Spaces will pretty much make many 3rd party software RAID options obsolete overnight. As well as hardware solutions like RAID storage enclosures and things like Drobo and ReadyNAS.
