The ideal solution for ground and air defense, industrial automation, transportation, medical and telecommunication applications, M4 2.5" SATA solid state drive (SSD) combines high performance, superior reliability and data security into a single ruggedized design. The SMART M4 SSD is designed to meet the needs of applications where temperature tolerances are as important as high performance and reliability. A robust set of diagnostic information is provided through SSD-specific S.M.A.R.T attributes which can be used to monitor the health of the drives.

The M4 features two HW-based erase triggers, one on each end of the drives. In addition, the SATA connect has 30 micro inches of gold plating for a more reliable connection. The M4 is also available with staking, conformal coating, specialty firmware and extended burn in, if needed.

Data Security
The M4 automatically protects all data written with AES 256-bit encryption. Also included is the Security Erase feature per the ATA-8 specification whereby the encryption key will be deleted in less than one second. SHRS' M4 SSD features write-protect.
