Differently than consumer SSDs, the industrial SSDs are often prone to sudden power loss, be it by unstable power lines or improper handling of the system. All Swissbit SSDs have a firmware based power fail protection that makes sure that the drive does not become corrupted or lose static data. The flash page translation tables in the DRAM are protected by special firmware actions. On top of this basic protection, the 2.5” X-60 uses additional capacitors to finish the ongoing flash write operation, reducing the risk of loss of write data. On the high end, the X-60P, where P indicates special power fail safety, uses a Pfail circuitry and a number of tantalum capacitors to store enough energy that the DRAM cache can also be hardened to the Flash. This protection level is the maximum that can be achieved without an uninterruptable power supply. To prove that the protection works, all Swissbit SSDs undergo a test where power is asynchronously interrupted 10,000 times at the connector of the device. A Swissbit device is qualified only if this test is passed.
