Yes, it will work just fine. In fact, I typically use lower-cost Seagate or Western Digital drives for bulk storage in DL180 G6 storage servers or where I need an extra array of SATA disks in an existing enclosure. Just replace the drive in the carrier with your new disk. Will you be using the HP Smart Array RAID controller? If so, the RAID will rebuild just fine.
Here's the hpacucli
