Dynamic random access memory, has to be constantly
What is DRAM?
refreshed so data doesn't disappear, the small black
boxes on RAM
Synchronous DRAM, will sync with common system
SDRAM?
clock and queue processes for the RAM
SDR = single data rate memory 1 clock

What happens with RAID 0?
high performance no redundancy
RAID 1? Mirroring, files duplicated on both drives, high redundancy
Striping with parity, parts of data scattered across
RAID 5?
drives with parity on the off ones, need at least 3
