SSD Level Opportunities

• Enhance MLC Flash life• Do not use standard flash settings• Advanced Signal Processing• Flash aggregation Take advantage of

population statistics

• Ensure enterprise reliability (BER 10-17)• Full Data Path Protection• Data Fail Recovery• Enhanced Error Correction

• Ensure 24x7 operation• Backup Power circuitry
