Notes:Health Monitoring only supports Synology Camera.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 a large number of products and may not accurately reflect actual operation. Actual operating life of the product may be different from the MTBF.Water-proof: water-resistant with IPX7 rating.Drop-proof: withstands 1.5-meter drops, tested over 10 cyclesWearout-proof: passes a durability test of 10,000 swipes.TBW estimation: TBW is affected by the write amplification factor (WAF), which varies depending on the write pattern. The formula is Estimated TBW ≈ Capacity × P/E Cycle ÷ WAF, where Capacity is the microSD card capacity and P/E Cycle is the number of program/erase cycles supported by the NAND flash. Since surveillance recording typically involves frequent small-file writes and deletions, WAF tends to be higher, and a value of 1.3 can be used as an estimation assumption. For example, for the MSD01-256G, the estimated TBW is approximately 256GB × 3,000 ÷ 1.3 ÷ 1,024 ≈ 577TBW.

Notes: Model specifications are subject to change without prior notice. The figures are based on Synology internal testing. Each performance test is done individually. No other services or applications are processed at the same time. The actual performance may be lower than lab testing figure due to differences in server configuration, deployment, and the number of active operations. If usage requirements exceed the specifications above, please contact our regional partners for professional advice.
