Popular storage and multimedia product manufacturer Transcend has launched a new line of SSDs with built-in 3D NAND flash. The new SSD230 solid state drives are claimed to offer improved transfer rates and greater reliability than products using 2D planar NAND flash technology.
In order to achieve higher densities, 2D planar NAND flash technology shrinks each memory cell onto a single layer of cells. This leads to higher cell-to-cell interference and reduces reliability as it approaches its physical scaling limit. 3D NAND flash technology resolves this bottleneck as it features multiple layers of memory cells stacked vertically. Additionally, the technology also boosts read and write performance, as it does not require the invocation of algorithms to prevent data corruption. Other advantages of 3D NAND flash include higher endurance as well as lower power consumption.
Equipped with a DDR3 DRAM cache and taking full advantage of the SATA III 6Gb/s interface with built-in SLC caching technology, the new Transcend SSD230 is claimed to achieve maximum transfer speeds of up to 560 MB/s read and 520 MB/s write. To keep your data secure, the SSD230 is engineered with a RAID engine and LDPC (Low-Density Parity Check) coding. It also features built-in wear-leveling technology to ensure data integrity during transmission, prolonging the lifespan of the drive.
Available in the industry-standard 2.5” form factor, the drive measures just 6.8mm in height and weighs in at just 63 grams, making it suitable for ultra-thin devices such as Ultrabooks as well as mainstream PCs and laptops. The SSD230 drives will be available in 128GB, 256GB, and 512GB capacities, backed by Transcend’s three-year limited warranty.
