112-Layer 3D NAND Flash

Transcend industrial storage solutions leverage the 112-layer 3D NAND flash to provide a more advanced performance at a competitive cost. Unlike the previous generation of technology which stacks memory cells to 96 layers, it allows 112 layers of NAND flash to be vertically stacked in a three-bit-per-cell architecture (TLC).

Early Move

Embedded applications require storage solutions that are both fast and accurate. These must also run uninterrupted under often harsh conditions. For greater accuracy and a prolonged lifespan, embedded SSDs and DRAM modules are equipped with Error Correction Code (ECC).

SLC Mode

SLC and MLC have differing advantages when it comes to durability and data retention. SLC Mode solves the inherent limitations of TLC and offers better reliability than MLC—equivalent to SLC—at an advantageous cost. In short, SLC Mode is a new alternative solution just right for industrial applications.

Power Shield (PS)

Data being written to SSDs is temporarily stored in DRAM cache memory before being transferred to NAND flash. This is done to take advantage of the quick response time of DRAM to boost the performance of the SSD. But as DRAM cache memory is volatile, an external power supply is required to hold and to flush data.

96-layer 3D NAND Flash

Most NAND flash memory on the market today stores one, two, or three bits of data per cell. Such types of flash are respectively called Single-Level Cell (SLC), Multi-Level Cell (MLC), and Triple-Level Cell (TLC). Of these, SLC has the best data retention, endurance, and reliability, as well as the highest cost, followed by MLC and TLC.

30µ” PCB Gold Finger

Gold fingers are the gold-plated connectors at the edge of printed circuit boards (PCBs). Shaped like a finger, they serve as connectors that connect the PCB to a motherboard, making sure a signal or command is reliably transmitted. Aside from the connectivity, the alloy also protects the edge of a circuit board from deterioration. Gold fingers are made of hard gold, or the Electroless Nickel Immersion Gold (ENIG). Its hardness at a specified thickness ranging from 3µ” to 50µ” ensures long-term component reliability.

Over-Provisioning

Over-Provisioning (OP) is a firmware optimization technology that allocates a certain portion of solid-state drive (SSD) capacity to the controller as cache. This allows the SSD to perform Garbage Collection (GC) more efficiently, helping maintain performance and increasing the SSD’s endurance and lifespan.

TRIM

Before learning what TRIM is, the first thing to know is that when you delete a file, the operating system does not directly remove deleted data from your HDD or SSD.

Bad Block Management

Bad Block Management detects and marks bad blocks, utilizes the reserved extra capacity to substitute the unusable blocks, and prevents data from being written to bad blocks, thus increasing product reliability.

Corner Bond

Embedded systems are marked by a need for small components, unmatched reliability, and the ability to withstand harsh conditions. Transcend Information offers corner bond as a customization option for its embedded products to increase reliability under high thermal or vibratory stress, high gravitational acceleration, and high fatigue cycle applications.

Underfill

Embedded systems are marked by a need for small components, unmatched reliability, and the ability to withstand harsh conditions. Transcend Information offers underfill as a customization option for its embedded products to increase reliability under high thermal or vibratory stress, high gravitational acceleration, and high fatigue cycle applications.

Extended Temperature

In contrast to wide temperature, extended temperature allows storage devices to operate stably from -20℃ to 75℃. The testing process is similar to that used for wide temperature, whereby chips are put into an exclusively-designed walk-in chamber.

Wide Temperature

Thanks to the advanced technology, flash and DRAM devices feature high endurance and reliable performance, making them useful for a wide range of applications, from industry, where long operating hours are required, to the military, where shocks and vibrations are regular occurrences, to vehicles where stability is a must, to the IoT, where ruggedness benefits users worldwide. To ensure that products have a long lifespan and low maintenance costs, wide temperature technology has become a bedrock feature of many devices.

Dynamic Thermal Throttling

When it comes to solid state drives (SSDs), most companies crave for high performance when SSD capacity increases. As an SSD works harder to meet companies’ growing demands, it generates more power, consequently creating more heat. If heat is not removed, the SSD temperature would exceed the expected operating condition, leading to potential hardware damage or data error.

Thermal Sensor

Though the general consensus is that, unlike traditional hard drives, Solid State Drives do not need cooling, for those SSDs on the higher-speed end of the spectrum, this might be another story.
