Dual Boot: same hard drive, or two?

UPDATE: My apologies. New user, posted before making account. Just read dual boot sticky, and plan to install one OS per drive as recommended. If there's any reason I shouldn't, feel free to chime in. Otherwise, mods please delete thread. Thanks!

My old HDD crashed, so I replaced it with a new SSD, on which I have win7 installed. During the replacement, I found a mSATA slot that I didn't know was there, so promptly ordered a 120gb mSATA SSD to go there. I am planning on dual booting with Ubuntu, and am wondering whether to put the Ubuntu installation on a separate partition of the original SSD (2.5") drive and use the mSATA strictly for data for both drives, or to give each OS its own drive.
I like the idea of having an OS on each drive, so that if one crashes, the other is available to run, but also like having all data on one drive and OSs on another. Which route is more highly recommended?
HP Pavilion dv6t-2100, win7/ubuntu

Actually, now have another question: If installing each OS on a separate drive, does it make sense to disconnect the drive that Win7 is on while installing Ubuntu on the other to prevent overwriting issues or should I leave both in during new install?

i agree with this, I dual boot win7 with some Linux distro all the time and I always set up the Linux drive as the "1st" boot hdd and never touch the windows drive with grub to avoid boot problems when and if I switch distros.
