TDK FLASH STOR STORAGE AGE DATA SHEET M.2 NGFF SATA 3Gbps M.2 SSD Series The SATA M.2 SSD is a new-generation form factor that is compatible with various kinds of interfaces. The M.2, which is employed in devices such as smartphones and tablet PCs, is a next-generation form factor (NGFF) developed by the SATA-IO. It is more compact and thinner by 65% than the conventional mSATA drive and compatible with interfaces such as SATA, PCI Express, USB, SD, Display Port, I2C, and UART. It is now even employed in industrial equipment and embedded devices. TDK’s SNG4A series is comprised of SATA 3Gbps M.2s mounted with TDK SSD controller GBDriver® RS4. With an enhanced ECC function that can extend to 71bit/512byte as well as a read retry □ BASIC CHARACTERISTICS / RATINGS data reliability that far exceeds that of the existing Data capacity Power supply voltage Ambient operating temperature Ambient storage temperature M.2 specification.

They are available in both 2242-D2-B-M and 2242-D5-B-M types. The series employs TDK SSD controller GBDriver® RS4, which determines SSD performance. The functions that increase reliability in read operations such as an enhanced ECC function, read retry function, and auto refresh function as well as the functions that increase reliability in write operations such as a □ MAIN APPLICATIONS □ FEATURES ® 1. Employed TDK SSD Controller GBDriver RS4. 2. Compatible with Serial ATA Standard Rev. 2.6 (Gen1: 1.5 Gbps, Gen2: 3.0 Gbps). Read 215 MByte/sec, Write: 95 MByte/sec. (*1) 3. Equipped with TDK's own static wear leveling algorithm. This algorithm counts the number of times each memory block is erased (programmed) and replaces blocks uniformly, which drastically improves the lifespan of the installed flash memory. (*2) 4. Equipped with data randomizer function. Data patterns are automatically randomized during the write process, to minimize the risk of bit errors due to writing the same data repeatedly. As a result of this function, data reliablility achieve greater in MLC. 5. data randomizer function, a write-back function for during power interruptions, and a global static wear levelling function allows optimal tuning in hardware and firmware designing. Security has also been enhanced with a password lock function, AES128 encryption function, and a complete data erasure function executed with the ATA Trim command. Furthermore, SSD Life Monitor Soft makes maintenance such as replacing drives easy. Equipped with an auto refresh function. While there is no access by the host, internal data are automatically refreshed. This function is paused during access, so there is no delay in response. 6. Equipped with an enhanced ECC function. An error correction ability of 71 bits/1 KByte is equipped as standard, and it can be extended up to 71 bits/512 Bytes (optional). 7. Equipped with read retry function. When an ECC error has occurred in a read operation, the GBDriver ® RS4 changes the read potential and at-tempts to read the data again. 8. TDK GBDriver® RS4 algorithm and an internal back up circuit in SSD reduces the risk of collateral data errors such as corruption of data other than the data being written if power is interrupted when writing data. 9. SSD life monitor software “TDK SMART” is included. 10. By using our life monitor software (TDK SMART), it is possible to accurately assess the lifespan of actual equipment. 11. Supports security functions based on ATA standards. Customers can set and remove passwords to prevent falsification of leaking of personal and confidential information. 12. Equipped with an encryption function AES (Advanced Encryption Standard) 128bit (optional). ● Thin-client computers, tablet computers, SATA RAID SSD installations, Data servers, Enterprise servers, embedded cloud systems and other IT equipment for cloud computing systems ● Digital tachographs, data logger, drive recorders, and rear-view monitors and other automotive equipment ● Multi-function printers (MFPs), commercial-use projectors, telephone conferencing systems, electronic blackboards and other office automation equipment ● Karaoke on demand systems, arcade games and other amusement equipment ● Semiconductor manufacturing equipment, NC machine tools, sequencers, programmable logic controllers, panel computers, embedded CPU boards and other factory automation equipment ● Automated ticket gates, automated ticket vending machines, commuter pass vending machines, train movement management systems, automated air ticket vending machines, automated check-in systems and other railway and transportation services equipment ● Cash registers and other point-of-sales (POS) equipment, convenience store and kiosk terminals, ATMs and other banking terminals ● Diagnostic imaging systems, blood analysis equipment, medical PCs, electronic patient records systems, DNA microarray systems, automatic biochemistry analyzers, remote medical care devices, automated care devices and other medical equipment and data analysis equipment ● Base station equipment for 4th generation (4G) mobile data communication systems such as LTE-Advanced/WiMAX2, data broadcasting system supporting digital broadcasting and other communications and broadcasting equipment and information system devices ● Biometric authentication systems, entry/exit control systems, security terminals for surveillance cameras and other security equipment ● Earthquake emergency information systems, household fire detectors and other disaster prevention related equipment 13.
