What is 3D MLC NAND Flash Memory?

To unleash performance fit for the next generation of computers, Transcend has released its MTE850 M.2 Solid State Device (SSD), based on 3D MLC NAND flash memory. The device utilizes the PCI Express Gen3 x4 interface and supports the latest NVMe standard. According to Transcend, this SSD targets high-end applications such as gaming, digital audio and video production, and multiple uses in the enterprise. Typically, such applications demand constant processing of heavy workloads, while not willing to stand any system slowdowns or lags of any kind. Transcend claims the MTE850 M.2 SSD will offer users high-speed transfers and unmatched reliability.

High Speeds for High-End Applications

As the above SSD uses the PCIe Gen3 x4 interface and follows NVMe 1.2 standard, it transmits and receives data on four lanes simultaneously. This results in the SSD working at the blazing speeds of up to 1100 MBps while writing, and up to 2500 MBps while reading.

Why the PCIe Interface

Presently, the most popular method of connecting a host computer to an SSD is through SATA or Serial ATA interface. However, PCIe uses one transmit and one receive serial interfaces in each of the four lanes, the PCIe interface is much faster than SATA is, and it is able to fulfill new performance requirements in better ways.

Why the NVMe Standard

The growing needs of enterprise and client applications demands better performance vectors than the Advanced Host Controller Interface (AHCI) can provide. The NVM Express (NVMe) fulfills this enhanced host controller interface standard, which also calls for low latency, increased IOPS, and scalable bandwidth.

What is 3-D Expansion?

Existing planar NAND memory chips are arranged in the form of flat two-dimensional arrays. In contrast, 3-D NAND flash has memory cells stacked in the vertical direction as well as in multiple layers. This breaks through the density limitations of the existing 2-D planar NAND, with the 3-D NAND offering a far greater level of performance and endurance.

With Better Endurance Comes Higher Reliability

To help keep data secure, Transcend has engineered their MTE850 M.2 SSD with a RAID engine (a type of data storage virtualization technology) and Low-Density Parity Check (LDPC) coding, along with an Elliptical Curve Cryptography (ECC) algorithm. Additionally, Transcend manufactures their SSDs with top-tier MLC NAND flash chips and provides them with engineered dynamic thermal throttling mechanism. This way, Transcend ensures the MTE850 delivers superior stability and endurance befitting for high-end applications.

SSD Scope Software

Users can download the SSD Scope software application free of charge from the Transcend site. The application helps to monitor the health of the running SSD using SMART technology and allows the user to enable the TRIM command to obtain optimum write speeds. Using the application also keeps the firmware of the SSD up-to-date, and helps in migrating data from the original drive to the new SSD with only a few clicks.

With certificates from CE, FCC, and BSMI the #-D MLC NAND flash memory based  MTE850 M.2 SSD from Transcend works on 3.3 VDC ±5%, operating within 0 and 70°C. With mechanical dimensions of 80x22x3.58 mm, the SSD weighs only 8 grams.
