yes, no problem at all. especially since your not doing RAID.
the rpm speed mostly affects the access time of the disc. if you look at the specs for the hard drive, the 10K rpm will probably have seek times in around 5ms, and the 7200 rpm will probably be around 7-8 ms.
my SATA drive is a slower 5400 rpm, and its access time is 8.9 ms.
for RAID applications, it would be best to match the HDD exactly, but still not required.
