Product Description 1.1 Introduction Apacer’s mSATA M4-M is a solid-state disk (SSD) drive in mini PCIe form factor that contains a controller, embedded firmware, and flash media along with a male connector. mSATA M4-M leverages the advantages of standard SATA SSDs in terms of wide compatibilities and reliable performance. Though built with MLC, this SSD can work in highly demanding environment as it can withstand ambient temperature from -40°C to +85°C (for certain capacities only). mSATA M4-M drive is designed with a single-chip controller, offering capacities of up to 128 gigabytes and is compliant with the SATA high-speed interface standard. Complying with JEDEC MO-300 standard, this mSATA SSD is the widely adopted embedded storage with compact size and exceptional performance. Ⅱ In addition, mSATA M4-M adopts the Apacer-specific global wear-leveling scheme to allow uniform use of all storage blocks, ensuring that the lifespan of a flash media can be significantly increased and the disk performance is optimized as well. mSATA M4-M provides the S.M.A.R.T. feature that follows the SATA Rev. 2.6, ATA/ATAPI-7 specifications and uses the standard SMART command B0h to read data from the drive. This feature protects the user from unscheduled downtime by monitoring and storing critical drive performance. 1.2 Functional Block Diagram Ⅱ mSATA M4-M drive includes a single-chip SATA Controller and the flash media, as well as the SATA standard interface. The controller integrates the flash management unit with the controller itself to support multi-channel, multi-bank flash arrays. Figure 1-1 shows the functional block diagram.

Rev. 1.8 Serial ATA Flash Drive APSDMxxxxM5XN-PCMX 3. Flash Management 3.1 Error Correction/Detection mSATA M4-M implements a hardware ECC scheme, based on the BCH algorithm. It can detect and correct up to 16 bits or 24 bits error in 1K bytes. 3.2 Bad Block Management Current production technology is unable to guarantee total reliability of NAND flash memory array. When a flash memory device leaves factory, it comes with a minimal number of initial bad blocks during production or out-of-factory as there is no currently known technology that produce flash chips free of bad blocks. In addition, bad blocks may develop during program/erase cycles. When host performs program/erase command on a block, bad block may appear in Status Register. Since bad blocks are inevitable, the solution is to keep them in control. Apacer flash devices are programmed with ECC, block mapping technique and S.M.A.R.T to reduce invalidity or error. Once bad blocks are detected, data in those blocks will be transferred to free blocks and error will be corrected by designated algorithms. 3.3 Wear Leveling Flash memory devices differ from Hard Disk Drives (HDDs) in terms of how blocks are utilized. For HDDs, when a change is made to stored data, like erase or update, the controller mechanism on HDDs will perform overwrites on blocks. Unlike HDDs, flash blocks cannot be overwritten and each P/E cycle wears down the lifespan of blocks gradually. Repeatedly program/erase cycles performed on the same memory cells will eventually cause some blocks to age faster than others. This would bring flash storages to their end of service term sooner. Wear leveling is an important mechanism that level out the wearing of blocks so that the wearing-down of blocks can be almost evenly distributed. This will increase the lifespan of SSDs. Commonly used wear leveling types are Static and Dynamic. 3.4 Power Failure Management Power Failure Management plays a crucial role when experiencing unstable power supply. Power disruption may occur when users are storing data into the SSD. In this urgent situation, the controller would run multiple write-to-flash cycles to store the metadata for later block rebuilding. This urgent operation requires about several milliseconds to get it done. At the next power up, the firmware will perform a status tracking to retrieve the mapping table and resume previously programmed NAND blocks to check if there is any incompleteness of transmission. 3.5 ATA Secure Erase ATA Secure Erase is an ATA disk purging command currently embedded in most of the storage drives. Defined in ATA specifications, (ATA) Secure Erase is part of Security Feature Set that allows storage drives to erase all user data areas. The erase process usually runs on the firmware level as most of the ATA-based storage media currently in the market are built-in with this command. ATA Secure Erase can securely wipe out the user data in the drive and protects it from malicious attack. 8 © 2013 Apacer Technology Inc. Rev. 1.8 Serial ATA Flash Drive APSDMxxxxM5XN-PCMX 3.6 S.M.A.R.T. S.M.A.R.T. is an acronym for Self-Monitoring, Analysis and Reporting Technology, an open standard allowing disk drives to automatically monitor their own health and report potential problems. It protects the user from unscheduled downtime by monitoring and storing critical drive performance and calibration parameters. Ideally, this should allow taking proactive actions to prevent impending drive failure. Apacer devices use the standard SMART command B0h to read data out from the drive to activate our SMART feature that complies with the ATA/ATAPI-7 specifications. Based on the SFF-8035i Rev. 2.0 specifications, SMART Attribute IDs shall include Initial bad block count, Bad block count, Spare block count, Maximum erase count, Average erase count and Power cycle. When the SMART Utility running on the host, it analyzes and reports the disk status to the host before the device reaches in critical condition. 3.7 TRIM TRIM, though in capital letters usually, is a memory computation command rather than an abbreviation. It is mainly a SATA command that enables the operating system to inform the SSD (Solid State Drive) which blocks of previously stored data are no longer valid, due to erases by the host or operating system, such as file deletions or disk formatting. Once notified, SSD will begin the discard of the invalid LBAs and retain more space for itself, in fact, the discarded is no longer recoverable. When an LBA is replaced by the operating system, as with overwrite of a file, the SSD is informed that the originally occupied LBA is determined as no longer in use or invalid. The SSD will not save those blocks in garbage collected sectors. Noticeably, a file deletion command by host or operating system never actually erases the actual content, rather, just the file is marked as deleted. This issue is even specifically noticeable for flash based memory devices, such as SSDs. In fact, an SSD will keep garbage collecting the invalid, previously occupied LBAs, if it is not informed that these LBAs can be erased. Thus, the SSD would experience a significant performance downfall. 9 © 2013 Apacer Technology Inc. Rev. 1.8 Serial ATA Flash Drive APSDMxxxxM5XN-PCMX 4. Environmental & Reliability Specifications 4.1 Environments mSATA M4-M environmental specifications follow the US Military Standard MIL-STD-810F, as shown in below table. Table 4-1 mSATA M4-M environmental specifications Environment Specification 0°C to 70°C (Operating) Temperature -40 ~ +85°C (operating-extended) -40°C to 100°C (Non-operating) Sine wave : 15(G), 10~2000(Hz), Random : 7.69 (Grms), 20~2000(Hz) Vibration Acceleration: 1,500 G, 0.5 ms Peak acceleration: 50 G, 11 ms Shock Note: extended operating temperature specification applies only to 16, 32, 64 and 128GB capacities. 4.2 Mean Time Between Failures (MTBF) Mean Time Between Failures (MTBF) is predicted based on reliability data for the individual components in mSATA drive. The prediction result for the mSATA M4-M is more than 1,000,000 hours. Notes about MTBF: The prediction is based on Bellcore analysis method by assuming device failure rate can be generated by the sum of failure rates in each component. 4.3 Endurance Terabytes Written (TBW) is an endurance rating system that indicates the maximum number of terabytes written by the host to the drive. NAND flash has a limit on how many P/E cycles it can withstand before its data retention becomes unreliable. Thus, key factors, such as Write Amplifications and the number of P/E cycles, can influence the lifespan of the drive. The TBW of the device are listed in the following table. Capacity Host Write (GB) TBW (TB) 8 GB 13509.93 13.5 16 GB 27019.86 27.01 32 GB 54039.73 54.03 64 GB 108079.47 108.07 128 GB 216158.94 216.15 Notes: The measurement assumes the data written to the SSD for test is under a typical and constant rate. The measurement follows the standard metric: 1 TB (Terabyte) = 1000 GB. 10 © 2013 Apacer Technology Inc.

Since the Virtual Write scheme runs at device level, it requires no software or driver installation and is independent from the host OS. 14 © 2013 Apacer Technology Inc. Rev. 1.8 Serial ATA Flash Drive APSDMxxxxM5XN-PCMX 7. Write Protect Enabled by Pin The pin 47 can enable “Write Protect” function. By default, the pin is set as “high” signal so that write operations can be performed normally. Once the signal is pulled to “low active”, Write Protect will be activated. Regarding the Write Protect function, it is implemented as “Virtual Write” and the description can be found in section 6.2. Pin 51 Pin 1 GPIO Trigger Impedance Signal Write Protect Low active since triggered Notes: Write Protect (Virtual Write) is a higher priority command than Erase or other erasure related commands. In other words, when Write Protect is activated, neither Erase nor other erasures can be activated. This pin is available in both the standard and the model with the hardware switch. There is no functional conflict as both the pin-configured and the switch-enabled Write Protect adopt the same GPIO pin in its hardware and firmware design. If the Write Protect is activated by the pin, it will be deactivated by the pin as well. The following table lists out the Write Protect status corresponding to the enabling/disabling of the pin/switch.
