Hello,
in RAID the most important thing - without the interface-type - is the correct amount of sectors. Further the access time and rpm is important.
At Seagate you can download the technical data for both Models.
"... 88BB998h Sectors of 512 Bytes ..." was explicite written for both models.
The ST373207LC is the successor (10.7) of the ST373307LC (10.6). The rest of technical Info ist quite identical.
Therefor you can use both models without fear ....
