Notes:

1. Workload is defined as the amount of data written, read, or verified by commands from a host system.

2. Mean time between failures (MTBF) is not an estimate or guarantee of product life. It is a statistical value related to mean failure rates for many products and may not accurately reflect actual operation. The actual operating life of the product may be different from the MTBF.

3. The warranty period starts from the purchase date, as stated on the purchase receipt.
