MSA490T & MSA490T-I


Transcend's MSA490T mSATA Solid State Drive features BiCS8 218-layer 3D NAND flash and built-in DRAM cache, delivering enhanced random read/write performance, higher storage density, and an endurance rating of 3K P/E cycles. With a standard SATA III 6Gb/s interface and compact mSATA form factor, the MSA490T is ideal for embedded industrial PCs, fanless systems, human-machine interfaces (HMIs), and self-service terminals where high-frequency data access and space efficiency are essential.

Built for long-term operation in demanding industrial environments, the MSA490T features a 30µ" PCB gold finger and Corner Bond technology for enhanced vibration resistance and component durability. The standard model supports an extended operating temperature range of -20°C to 75°C, while the industrial wide-temperature MSA490T-I supports a wide operating temperature range of -40°C to 85°C. The MSA490T series provides a dependable storage solution for demanding applications such as smart manufacturing, outdoor terminals, and edge computing.
