Why would RAID0 not be recommended for a boot partition?
Here's the skinny OP:
RAID0 gets you all of the space of both disks, and roughly double the write and read speed (since it stripes both). However, it adds no redundancy and because any of the two disks failing can cause the entire array to fail, it actually increases the probability of a failure over a single disk.
That said, the likelihood of a failure is very slim, and you should be taking regular backups of your important documents, pictures, and other data regardless of the storage system you use. There is absolutely no reason to not use RAID0 for your boot volume.
I've been doing it for more than 10 years with multiple different RAID controllers and chipsets and have not once encountered an issue, I also fundamentally understand how RAID works at a controller level and there is absolutely no reason I can think of why it'd be ill-advised for your boot volume. The risk is the same whether you are doing it for a boot or non-boot volume.
Just make sure you make and keep regular backups and you should be fine. Enjoy the doubled space and increase in performance.
The previous commenter is correct however that when you create the RAID0 volume it will wipe both of the disks. It does this because when your OS formats the volume with a filesystem before installing, it must do so across the entire array, rather than the individual disks in the array. So before you create the RAID0, make sure you've copied any data you wish to keep elsewhere and have installation media available for any of the applications you wish to reinstall.
