Use an M.2 drive for Windows
The Skylake motherboard has 6 connections for hard drives and DVD/Blu-ray writers, plus a new type of hard drive connection for an "M.2 drive". M.2 drives are made of the same kind of memory as solid state drives but are built into a circuit board and plug directly into the motherboard. They are generally faster than Solid state drives, with the very top models managing speeds of 6GB/s or even more. The best use for the M.2 is as a drive for Windows as the system will boot faster and programs will open quicker. This will also leave the other 6 hard drive connections free for you to add whatever combination of hard drives and optical drives you prefer.
You do not have to use an M.2 drive for Windows but there is very little reason not too as they are a very similar price to Solid state drives. The only reason you may choose to use a different drive is if you want the option to easily swap your main drive - for example you have two different versions of Windows on the same machine and want to easily swap between them, so would want the main drives in caddies as the M.2 drive is screwed into the motherboard and probably obscured by all sorts of things inside the PC case.
Can I have two Blu-ray writers?
Yes. Many people would like to this so they can copy a disc directly from one drive to another. In our experience a direct copy like this works well for DVDs, but is not so reliable for copying Blu-ray discs. If you are copying Blu-ray discs the best option is to make an image on the computer first and then write that to a disc, for which you would only need one drive.
I want 6 6TB drives but that is not an option, why?
We did not add this as an option simply because this page is very long and we did not think it would be an option many people would want. Please contact us if you want some combination of drives that is not listed.
I want all my drives in caddies, is this possible?
Yes. The current quiet cases only support 2 front facing drive bays, both of which will be used with the card reader and optical drive. If you want 4 or 5 drives in removable bays we can do this but would need a different case as well as the removable bays. Please contact us to discuss your options.
