Transcend’s 2.5″ SATA III SSD452P and SATA III M.2 SSD MTS952P tap Intelligent Power Shield (IPS) technology to deliver greater stability for industrial applications. Engineered with 3D NAND flash, these two types of solid-state drive (SSD) feature huge capacity by stacking memory cells vertically up to 96 layers for endurance as high as 3K P/E cycles.
Transcend provides extended-temperature models that ensure reliable operations from -20°C to 75°C. In addition to IPS for greater data integrity, the built-in LDPC Error Correction Code (ECC) function guarantees the data can be written correctly in firmware. This feature improves the overall performance in mission-critical applications on servers, workstations, and mobile computing devices.
Why do we need IPS?
When an SSD is in operation, the built-in DRAM cache memory temporarily stores data. This allows faster response time and lower latency while data is being stored to long-term NAND flash. The drawback is that DRAM cache is volatile memory.
If a sudden power outage occurs, data in transit can neither be stored on nor flushed to the flash memory. In this case, data stored on the SSD is not updated, which can lead to a problem with data incompatibility, data corruption, or even total device failure.
