ADATA Releases Updated SC660H and SV620H 3D NAND External SSDs

Fast and reliable storage expansion in two stylish designs

ADATA Technology, a leading manufacturer of high performance DRAM modules, NAND Flash products, and mobile accessories today launched the updated Premier SC660H and Premier SV620H external SSDs.

Based on previous designs, the new models are part of the ADATA move to 3D NAND Flash in all new SSDs and in refreshes of existing models. The SC660H and SV620H feature 3D TLC NAND instead of traditional 2D NAND to provide increased reliability, durability, and efficiency. The drives connect to host PCs via USB 3.1 Gen 1, and are presented in two distinct enclosure styles. Thanks to 3D NAND, the updated SSDs are available in 256GB and 512GB as opposed to 240GB and 480GB in the original SC660/SV620. Performance is 440MB/s read and 430MB/s write in both models.

SC660H: ultra-thin and tough elegance 
The SC660H measures just 9.6mm tall. Its slim enclosure uses electroplated and textured titanium, ensuring a high degree of resistance against shocks, scratches, paint chipping, and fingerprints. The SC660H weighs a mere 73g, a fraction of the bulk of an external mechanical hard drive.

SV620H: elevating external SSD design
Also light and slender, the SV620H likewise employs a sandblasted titanium enclosure that makes it shock and scratch resistant. Its flat surfaces are raised 0.75mm, so that even when moved across a desk or other area the risk of unsightly scratches is minimized. The SV620H weighs 76g, and like its SC660H sibling has a cool blue activity LED.

Bigger capacity in the same space plus added reliability
The 3D TLC NAND used on the two external SSDs is more reliable than 2D NAND and enables “packing” more storage into identical product chassis. At 256GB and 512GB, the SC660H and SV620H offer more space than their predecessors without consuming extra power. They are extremely efficient and ideal for notebook PCs thanks to placing very little stress on batteries. Like all SSDs, they run totally silent and cool. With their 3D NAND, the SC660H and SV620H simply offer a better value than 2D NAND-based external SSDs, representing another step in ADATA embracing new technology to benefit consumers worldwide.
