Comparing 2D NAND vs. 3D NAND SSD

  Flash-based SSDs, or solid state drives, were invented in the 1980s, so it is not surprising that the technology has progressed significantly since then. The main drive in improving SSDs has always been scaling, focusing on fitting more data into the same sized space. For many years, this effort was limited by the fact that NAND flash was planar. In other words, 2D NAND flash was the only available technology, thus creating an upper limit for the capacity of Read More...

What Is 3D NAND Flash?

  Most NAND flash drives are designed with planar NAND technology—in other words, the cells are arranged in a 2D format. This design is effective, but it has some limitations and challenges. The introduction of 3D NAND flash changes that. 3D NAND flash can be used in both commercial and industrial applications in the same way that planar NAND flash is, often with some advantages. As with all forms of NAND flash, 3D NAND flash offers lower latency rates and Read More...

SSD Wear Leveling Tests

  Solid state drives, or SSDs, have many advantages over hard disk drives (HDDs). Since SSDs don’t have moving parts, they don’t fall victim to the mechanical failures that can plague HDDs. They never develop magnetic problems on the platters, since there are no platters to spin. Of course, there is a trade off. SSDs have a finite number of writes that they can perform depending on the kind of flash memory that they use for storage. Wear leveling is Read More...

A Closer Look at Read Disturb Errors

  When NAND flash memory is used only for read operations, many designers believe that they do not have to worry about product lifespan, since no writing is occurring. In reality, even read operations can eventually wear the flash memory out, as repeated read operations can lead to inadvertent reprogramming and damage caused by cross-coupling noise. When these issues occur, they are called read disturb errors. Fortunately, industrial-grade NAND flash memory typically comes with read leveling and ECC integrated to Read More...
