Renice Announces X9 Military-Grade Rugged SSDs with R-SATA Connectors

Shenzhen Renice Technology, a little-known maker of special-purpose SSDs from China, has introduced its new family of drives designed for military and rugged applications. What makes these new drives notable is that they are designed to withstand harsh environments, utilizing special R-SATA connectors as well as custom controllers. On the NAND side the drives are build around SLC, MLC or pseudo-SLC NAND flash memory to provide the required balance between endurance, price and performance.

The Renice X9 R-SATA SSDs are powered by the company’s own controller, the RS3502-IT, as well as SLC or MLC NAND flash memory from undisclosed manufacturers. The drives are made in accordance with the MIL-STD-810F spec to withstand harsh environments and poor handling, and feature integrated power failure protection as well as 256-bit AES encryption with several secure erase functions (both software and hardware). The Renice X9 SSDs use the company’s proprietary 15-pin R-SATA connectors as well as special 7-pin SATA power ports, which limits compatibility of the drives to applications that feature the same connectors.

The SLC-based X9 R-SATA drives are offered in 128 GB – 1 TB configurations, whereas MLC-powered SSDs are available with 256 GB – 2 TB capacities. If required, Renice can use MLC NAND in pseudo-SLC mode in order to provide higher endurance and performance at a predictable cost. The Renice X9 comes in 2.5” form-factor with 7, 9 or 15 mm thickness, depending on the exact capacity configuration.

The manufacturer claims that the X9 SSDs have maximum sequential read speed of up to 530 MB/s and maximum sequential write speed of up to 500 MB/s along with  0.1 ms access time. The company does not specify random read/write performance of the drives, but claims that it is “excellent”. Keeping in mind that X9 SSDs can use different types of NAND flash memory and come in various configurations, random I/O performance of different models is likely to vary greatly.

With regards to reliability, the Renice X9 drives boast a MTBF of over four million hours, while their physical tolerance is rated for 16.4G (10 – 2000 Hz) sustained vibration and 1500G (@ 0.5 ms half sine wave) shock, something that typical drives simply do not offer (Intel’s DC S3710 SSD, by comparison, can tolerate 2.17 G operating vibration and can survive 1000 G shock). The X9 SSDs are designed for operating temperatures ranging from -40°C to +85°C (industrial-grade) or even -55°C to+125°C (military-grade), which is in line with other SSDs for extreme environments (such as those from Amtron or Foremay). Meanwhile, datacenter drives like the DC S3710 can operate when its temperature is between 0ºC and +70ºC.

Given that Renice is a Shenzhen-based company, it is admittedly unlikely that the X9 SSDs will be used in military or defence applications outside of China. Nonetheless, since the drives are designed to withstand harsh environments in general, the X9 SSDs can be used in aerospace, industrial, transportation, outdoor storage and other systems that are subject to extreme temperatures, severe vibrations and other types of harsh environments.

Exact pricing of the Renice X9 depends on memory configuration and additional features that the manufacturer may offer (e.g., extended operating temperatures). Typically, rugged drives cost significantly more than typical SSDs.

Toshiba to Build New Fab to Produce BiCS NAND Flash

Toshiba this month has announced plans to build a new manufacturing facility to produce its BiCS NAND flash memory. The company intends to start making chips at the new fab in 2018 and currently is not disclosing the planned production capacity of the…

Samsung Readies New Cost-Effective SSDs Featuring Maia Controller

Thanks to introduction of the PCIe-based M.2 form-factor and subsequent removal of SATA III bandwidth constraints, the evolution of high-performance SSDs has been quite spectacular in the recent years. Nonetheless, there are plenty of SSDs which still rely on SATA and will continue to use SATA. Such devices can be used to upgrade previous-generation PCs or inside new low-cost notebooks. To address this market, Samsung has revealed that they are working on their all-new Maia controller and SSD platform for SATA, laying out how they intend to continue to evolve SATA SSDs.

The new Samsung Maia controller supports multiple types of NAND flash memory, including TLC and 3D NAND/V-NAND. At the Samsung SSD Forum Japan, the company demonstrated two new SSDs based on the Maia chip. Both drives come in 2.5” form-factor and with a SATA III (6Gbps) interface. Initially Samsung intends to use the controller to build drives for OEMs, but as is often the case with Samsung, it is quite possible that it will eventually show up in retail SSDs as well.

The new Samsung CM871a OEM SSD based on the Maia controller will feature Samsung’s 16nm TLC NAND, which indicates that the company has no plans to drop production of planar NAND flash memory for consumer SSDs any time soon. The drive is rated for maximum sequential read speed of up to 535 MB/s as well as sequential write speed of up to 215 MB/s in default mode or up to 515 MB/s with TurboWrite technology active. Like many modern TLC NAND-based SSDs, the CM871a uses part of the non-volatile memory in SLC mode for rapid caching. The SSDs can perform up to 97K random read IOPS as well as up to 59K random write IOPS (or 88K IOPS with TurboWrite technology). Samsung will offer its CM871a in 128 GB and 256 GB configurations, which indicates that the family was designed for the low end of the market.

Meanwhile the Samsung PM871a will use the Maia controller alongside TLC V-NAND memory. According to Samsung, the drive has maximum sequential read speed of up to 530 MB/s and maximum sequential write speed of up to 515 MB/s (or up to 526 MB/s with TurboWrite). Random read performance of the PM871a is up to 97K, whereas random write performance of the drive is up to 88K IOPS. Samsung plans to offer its PM871a SSDs in 128 GB, 256 GB, 512 GB and 1 TB configurations. Samsung does not specify whether it utilizes its third-generation 48-layer V-NAND memory for the drives, or some drives continue to use previous-gen memory. While usage of 256 Gb TLC V-NAND for high-capacity SSDs makes a great sense, a 128 GB drive would in this case require only four such memory dies, limiting parallelism and is a solid example as to why manufacturers have been hesitant to produce small drives with cutting-edge high-density NAND.

These drives would be replacing Samsung’s exisitng product line such as the PM871, which we have limited information about (given slow writes, it is logical to assume that it uses TLC NAND, but that is not something confirmed by Samsung). Meanwhile in the retail channel Samsung sells the inexpensive 850 EVO and 750 EVO SSDs. These SSDs are based on the company’s MGX controller, coupled with the company’s second-gen 32-layer TLC V-NAND or 16 nm planar TLC, respectively. The aforementioned drives offer performance levels very similar to those of the forthcoming CM871a and PM871a, which may indicate that Samsung’s new Maia platform focuses mostly on cost efficiency, endurance and predictable performance, but not on maximum sequential read or random IOPS numbers (especially given limitations of SATA). Nonetheless, the development of Maia shows that SATA is still an important part of the market for Samsung as lower-end PCs continue to rely on it.
