■ Endurance

JEDEC defined an endurance rating TBW (TeraByte Written), following by the equation below, for indicating the number of terabytes a SSD can be written which is a measurement of SSDs' expected lifespan, represents the amount of data written to the device.

TBW = [(NAND Endurance) x (SSD Capacity)] / WAF

• NAND Endurance: Program / Erase cycle of a NAND flash.

• SLC: 100,000 cycles
• Ultra MLC: 30,000 cycles
• MLC: 3,000 cycles
  ○ 3D TLC (BiCS3): 3,000 cycles

• SSD Capacity: SSD physical capacity in total of a SSD.

- WAF: Write Amplification Factor (WAF), as the equation shown below, is a numerical value representing the ratio between the amount of data that a SSD controller needs to write and the amount of data that the host's flash controller writes. A better WAF, which is near to 1, guarantees better endurance and lower frequency of data written to flash memory.

WAF = (Lifetime write to flash) / (Lifetime write to host)

Endurance measurement is based on New JEDEC 218/219 Client Workload and verified with following workload conditions,

• PreCond%full = 100%
• Trim commands enabled
• Random data pattern.

4. General Description

■ Error Correction Code (ECC)

Flash memory cells will deteriorate with use, which might generate random bit errors in the stored data. Thus, SQFlash 840 series SSD applies the LDPC with RAID ECC algorithm, which can detect and correct errors occur during read process, ensure data been read correctly, as well as protect data from corruption.

■ Wear Leveling

NAND flash devices can only undergo a limited number of program/erase cycles, and in most cases, the flash media are not used evenly. If some areas get updated more frequently than others, the lifetime of the device would be reduced significantly. Thus, Wear Leveling is applied to extend the lifespan of NAND Flash by evenly distributing write and erase cycles across the media.

SQFlash provides advanced Wear Leveling algorithm, which can efficiently spread out the flash usage through the whole flash media area. Moreover, by implementing both dynamic and static Wear Leveling algorithms, the life expectancy of the NAND flash is greatly improved.

■ Bad Block Management

Bad blocks are blocks that include one or more invalid bits, and their reliability is not guaranteed. Blocks that are identified and marked as bad by the manufacturer are referred to as "Initial Bad Blocks". Bad blocks that are developed during the lifespan of the flash are named "Later Bad Blocks". SQFlash implements an efficient bad block management algorithm to detect the factory-produced bad blocks and manages any bad blocks that appear with use. This practice further prevents data being stored into bad blocks and improves the data reliability.

■ Power Loss Protection

- Flush Manager

Power Loss Protection is a mechanism to prevent data loss during unexpected power failure. DRAM is a volatile memory and frequently used as temporary cache or buffer between the controller and the NAND flash to improve the SSD performance. However, one major concern of the DRAM is that it is not able to keep data during power failure. Accordingly, SQFlash SSD applies the Flush Manager technology, only when the data is fully committed to the NAND flash will the controller send acknowledgement (ACK) to the host. Such implementation can prevent false-positive performance and the risk of power cycling issues. In addition, it is critical for a controller to shorten the time the in-flight data stays in the controller internal cache. Thus, SQFlash applies an algorithm to reduce the amount of data resides in the cache to provide a better performance. With Flush Manager, incoming data would only have a “pit stop” in the cache and then move to NAND flash directly. Also, the onboard DDR will be treated as an “organizer” to consolidate incoming data into groups before written into the flash to improve write amplification.

– Voltage Stabilizer (optional)

While the built-in voltage detector detects an unstable power input (< 4.75 V or > 5.25 V), the controller will issue a power failure interrupt and force a Flush CMD first. At the same time, the whole internal power supply will be switched to Voltage Stabilizer immediately to ensure stable power is supplied throughout the whole drive. This ensures the Flash IC and DDR IC will not operate with unstable power which could lead to data errors or bad data integrity.

TRIM

TRIM is a feature which helps improve the read/write performance and speed of solid-state drives (SSD). Unlike hard disk drives (HDD), SSDs are not able to overwrite existing data, so the available space gradually becomes smaller with each use. With the TRIM command, the operating system can inform the SSD which blocks of data are no longer in use and can be removed permanently. Thus, the SSD will perform the erase action, which prevents unused data from occupying blocks all the time.

■ SMART

SMART, an acronym for Self-Monitoring, Analysis and Reporting Technology, is an open standard that allows a hard disk drive to automatically detect its health and report potential failures. When a failure is recorded by SMART, users can choose to replace the drive to prevent unexpected outage or data loss. Moreover, SMART can inform users of impending failures while there is still time to perform proactive actions, such as copy data to another device.

■ Over-Provision

Over Provisioning refers to the inclusion of extra NAND capacity in a SSD, which is not visible and cannot be used by users. With Over Provisioning, the performance and IOPS (Input/Output Operations per Second) are improved by providing the controller additional space to manage P/E cycles, which enhances the reliability and endurance as well. Moreover, the write amplification of the SSD becomes lower when the controller writes data to the flash.

■ Thermal Throttling

Thermal Throttling function is for protecting the drive and reducing the possibility of read / write error due to overheat. The temperature is monitored by the thermal sensor. As the operating temperature continues to increase to threshold temperature, the Thermal Throttling mechanism is activated. At this time, the performance of the drive will be significantly decreased to avoid continuous heating. When the operating temperature falls below threshold temperature, the drive can resume to normal operation.

5. Security Features

■ Advanced Encryption Standard (AES)

An AES 256-bit encryption key is generated in the drive's security controller before the data got stored on the NAND flash. When the controller or firmware fails, the data that is securely stored in the encryption key becomes inaccessible through the NAND flash.

■ Secure / Quick Erase

SQFlash 840 series supports standard SATA command secure erase. Also, with internal AES encryption support, the erase process will start with resetting AES key. By doing so, existing data will be scrambled within 10ms and cannot be recovered anymore. Moreover, erase flag is set when erase function is triggered, which will ensure the whole erase process can be 100% completed. Even there's power interrupt, after power resume, erase operation will be resume right away as well.

■ TCG-OPAL 2.0 Compliance

TCG-OPAL compliance SED (Self-encryption Drive) supports a built-in shadow MBR to process user authentication to SSD before booting to normal MRR area and OS. SQFlash 840 series supports such feature with 100% TCG-OPAL compliance. Further, with SQFlash Flash Lock function, the user authentication process in shadow MBR can be done automatically by bonding with motherboard unique ID such as UUID in BIOS / MAC address / TPM unique code. So with Flash Lock enabled, only designated motherboard can have access to the SSD.

■ Write Protect

SQFlash 840 series supports Write Protect function though firmware setting. Users can perform write protection through SQFlash Smartwp software in DOS interface. The SSD will not execute Write command to perform write protection function by issuing write protection enable command through the DOS interface.

■ Flash Vault

Flash Vault is to lock Read and Write command by SSD firmware setting and make the SSD need password to verify and only operate with the corresponding platform. User can use Flash Vault to prevent data being stolen by reading the SQFlash SSD with other computers and unauthorized person.

■ Security ID

Security ID is to encrypt user's specific application software encryption. To enable this function, the application software is required to build Security ID function code and user needs to enable the firmware function by entering Access Code of SQFlash Utility, and then the Security ID can be set. When Security ID sets, the application software is protected by Security ID and SQFlash Utility

6.3 Hardware Quick Erase / Write Protect (Optional, either one support only)

• The Hardware Quick Erase is a function of overall destruction. Once the function is triggered, the SSD controller will set erase flag and reset AES key within 10ms and then all the data in Flash IC will become scrambled data. The SSD will be inaccessible immediately and will be in erase mode before erase process is completed. After that, the new mapping table will be generated. Even there is power failure during the process, erase will be carried on after power resume. Optionally, the function can be set to several different erase protocol, also, can be set to end up with removing firmware and mapping table to make SSD become unusable anymore.
• Write Protect is a function of prohibiting writing data into drive. When the reserved GPIO pins are shorted or pull to 3.3V, all of the write command will be carried to a buffer area without real programming to the Flash IC. So the data won't be saved in this mode and will be totally discarded upon power shutting down.
• GPIO pin is reserved on the PCB without any default function. Optionally the pin can be set to either Quick Erase or Write Protect by loading the specific version firmware. Please contact Advantech sales representative if you would like to enable the function.

The SECURITY ERASE PREPARE command shall be completed immediately prior to the SECURITY ERASE UNIT command.

26. SECURITY FREEZE LOCK (code: F5h);

This command shall set the device to frozen mode. After command completion any other commands that update the device Lock mode shall be command aborted. Frozen shall be disabled by power-off or hardware reset.

If SECURITY FREEZE LOCK is issued when the drive is in frozen mode, the drive executes the command and remains in frozen mode.

27. SECURITY SET PASSWORD (code: F1h);

This command transfers 512 bytes of data from the host. Table defines the content of this information. The data transferred controls the function of this command. Table defines the interaction of the identifier and security level bits.

28. SECURITY UNLOCK (code: F2h);

This command transfers 512 bytes of data from the host. Table (as Disable Password) defines the content of this information.

If the Identifier bit is set to Master and the device is in high security level, then the password supplied shall be compared with the stored Master password. If the device is in maximum security level then the unlock shall be rejected.

If the identifier bit is set to user then the device shall compare the supplied password with the stored User password.

If the password compare fails then the device shall return command aborted to the host and decrements the unlock counter. This counter shall be initially set to five and shall be decremented for each password mismatch when SECURITY UNLOCK is issued and the device is locked. When this counter reaches zero then SECURITY UNLOCK and SECURITY ERASE UNIT command shall be aborted until a power-on or hardware reset.
