Apologies if this is a rather silly question, but I'm not very savvy when it comes to interpreting server documentation. The documentation (http://h18004.www1.hp.com/products/quickspecs/12527_na/12527_na.HTML) specifies that the maximum storage possible for this server is 4.5TB resulting from 6x750GB drives. It also mentions support for smaller drives (500GB, 250, etc.) but not larger ones. Since the total it can handle is 4.5TB, does this mean that it could support 4x1TB drives? My concern is that the hardware wouldn't be able to read the drives properly since 1TB is greater than the maximally "supported" capacity of 750GB drives. Is this concern unfounded or would the server not be able to use 1TB drives? I have searched around for an answer but have not been able to find one.
Thanks

The issue here is at the side of the RAID controller. The RAID controller may or may not support larger drives.
If the server you have got has a E200 RAID controller, you have a good chance to succeed. From the specifications of the RAID controller in question HP E200/128 BBWC it supports SATA disks up to 3TB. So it is likely, that your system will work with large disks.
The reason this is not shown in the spec is that HP stops updating the specifications when it stops selling the product. ML150 G3 as the spec says was retired in 2008.
Your best bet is to get hold of a terabyte drive, install it into the system and see if it is recognized and its full capacity is being used.
Also make sure that you have the latest firmware for the RAID controller.
Certainly HP would not support this configuration if it does not work.
