Notes:
1. Performance measured after SSD preconditioning
2. Tested with IOmeter 08 and queue depth (QD) set to 32.
3. Write Cache enabled.
4. Random IOPS (Input/Output Operations per Second) cover the entire range of legal logical block
addresses (LBA’s). Measurements are performed on a full drive (all LBA’s have valid content).
5. Performance may vary by NAND type and host.
6. Refer to Application Note AN0006 for Viking SSD Benchmarking Methodology.
