SSD in early 2008 Xserve Apple Drive Module

Pretty much the title: it possible to use a modern, 2.5″ SSD in an Apple Drive Module on a early 2008 Xserve? This would be replacing a 15k RPM SAS drive, and in most places I've looked that HDD is almost as expensive than a similarly sized SSD.

SSD on Vmware ESXI 4 (TRIM? Good Idea?)
