Transcend: SSD230 With 3D NAND Flash

Transcend Information, Inc. launched an SSD with built-in 3D NAND flash.

With the needs for high-capacity and high-performance storage, the company has adopted 3D NAND flash technology for its 2.5″ SSD230 SSDs, boosting storage capacity, transfer rates, and reliability.

3D NAND Flash Technology for Upgraded Capacity, Performance, and Endurance
To achieve higher densities, 2D planar NAND flash technology shrinks each memory cell onto a single layer of cells. However, this technology increases cell-to-cell interference and hence reduces reliability as it approaches its physical scaling limit. 3D NAND flash was developed to resolve this bottleneck, as it features multiple layers of memory cells stacked vertically. It resolves the density limitations of 2D horizontal NAND, and boosts read and write performance, as it does not require the invocation of algorithms to prevent data corruption. Free from cell-to-cell interference, 3D NAND flash technology also features higher endurance and lower power consumption.

Up to 560MB/s and Enhanced Reliability
Besides built-in 3D NAND flash, the SSD230 is equipped with a DDR3 DRAM cache that provides an 4K random read and write performance of up to 340MB/s, making it a boot disk for everyday computing tasks and programs. Taking advantage of the 6G SATA interface and built-in SLC caching technology, the SSD230 achieves sequential transfer speeds of up to 560MB/s read and 520MB/s write. It also features a RAID engine and LDPC (Low-Density Parity Check) coding, an ECC algorithm, to keep data secure.

SSD Scope Software
Developed for download and use with Transcend’s SSD products, SSD Scope is a software that makes it easier to maintain a healthy and efficient SSD. This software brings together the technology to determine the condition and optimize the performance of an SSD. SSD Scope’s useful features include: drive information and S.M.A.R.T. status monitoring, diagnostic scan, secure erase, firmware update, TRIM enabling, health indication, and system clone.

SSD230 SSDs are offered in 128GB ($51), 256GB ($82), and 512GB ($162) capacities and backed by three-year limited warranty.
