QmerCam,   You can find a couple different sized SSDs here.   Let me know if this helps.    
Hello. I have 2 Dell Poweredge R720. I want to change their disks to SSD. I could not find any compatible SSD list on web or forum.  I want to add 1 TB or 2 TB SSD's. Is there any product ID or compatible list ?    Thank you.
