The heat is normal. That heat generated by 7200rpm hard drive and the ICs used in NVS2525. But don't worry. NVS2525 is verified to work at 50 cellcius temperature for one week constant use.
The problem of slow copy speed might come from fragmentation of hard drive or hard drive almost full.
We recommend you periodicaly format the NVS2525 using its format function to get best performance.
