Basic disk information like model name, serial number, and firmware version will be revealed in this field. All available S.M.A.R.T. attributes are also displayed for users to monitor disk conditions.
- Max Program - Max program and erase cycles in SQFlash.
- Average Program - Average program and erase cycles in SQFlash.
- Power On Time - Power on accumulated time.
- ECC Count - Error correction code number of times counter.
- Endurance Check - Endurance (%) of remaining life is the result of (Average P/E cycles) / (Max P/E cycles).
SQFlash Integrated Software Security Features
In order to help protect customers’ intellectual property, Advantech has designed in a Security ID feature for Advantech SQFlash. Customers can easily implement security functions on their applications based on an encrypted utility and library. The Flash Lock feature helps users to lock SQFlash with the motherboard it operates on to protect flash data from being read.
- Security ID I
Security ID I can be a full run-time configuration. All read/write access can be performed immediately. After Security ID I is enabled, all disk management access would be disabled, e.g. Format, fdisk, ghost, etc. This is because the SQFlash controller protects the SID area and does not allow any disk I/O to read or write to this area. If any tool or command tries to access this area, it will return a fail instruction.
- Security ID II
This SID will be located into the firmware zone and all disk management access will maintain the same behavior.
Flash Lock is a mechanism to lock SQFlash with the motherboard through the BIOS and make SQFlash only operate with the corresponding platform. This can help to prevent data being stolen by reading the SQFlash with other computers and card readers. Since the feature is a mechanism between the SQFlash firmware and BIOS, it can work only on Advantech products. If the target platform doesn’t support this feature, Flash Lock buttons will be grayed out as follows.
Advanced Hardware Security Functions
SQFlash 820 series SATA III SSD is designed with the Opal Compliant disk encryption standard, which supports in-drive AES 256-bit encryption. For even more critical applications that may need emergency erase, the SSD is equipped with hardware GPIO pins for triggering a high security level erase-at-once command.
