We need a thread to gather info about the Windows 8 and Server 2012 storage drivers.
I'll start with what I've found so far (not much ) but it will be expanded to raid testing tomorrow.
First of all, W8 installation is fast, faster than W7.
I have performed several installations of W8 but installing on a SB (P8P67 Deluxe) computer is the first for me, the others were Virtual Machines.
To see how the default driver performs I performed a standard installation.
One thing I did notice was that the "hidden" partition has increased in size from 100MB to 350MB, not an issue but still, it has changed.
Drive used for single drive testing is a Vertex 4 128GB. (over-provisioned to the Xtreme)
The beta (22.214.171.1247) looks to be the better performer but it needs more testing.
Also, there is built in functionality for TRIMming single drives using the standard Optimizer. (where you used to defrag)
Will be testing raid tomorrow.
WEI is still there and it has changed, the Vertex 4 scored 8.0 in the "Hard disk test", will need to try other drives to get a feeling with how the score has changed.
The page file is still here, this PCs got 8GB and it allocated 4GB which is an improvement vs earlier versions. (normally 1.5x installed memory)
I did not check if the hibernation file has changed, it was enabled though and I disabled it.
The footprint is about 8.5GB when the pagefile and hibernation disabled.
So, raid and Windows Server 2012 will follow next.
I have already installed WS2012 in VMWare but a "normal" install is needed.
From the storage perspective there are some quite interesting things on Windows Server 2012.
