V-NAND Vs 3D NAND – What’s The Difference?
The recent increase in storage size for both hard drives and solid-state drives has led to plenty of new terms which can confuse potential buyers to the point where they default to things they either heard were good or have at some point been good but are now outdated.
SSD technology has moved from SATA to NVMe, using M.2 and U.2 connectors, but beware of the different M.2 sizes, like 2280, 2260, 2242.
With so many names for different terms, how is one to understand NAND flash, particularly V-NAND vs 3D NAND? Here are a couple of explanations to help you understand NAND, particularly 3D NAND and V-NAND.
NAND Flash – 3D or V?
It will take a simple trip back in time, to Q3 of 2013, to find that there is no 3d nand vs v nand and that they refer to the same thing. V-NAND, as it is called, is a marketing name for 3D NAND, created by Samsung back in 2013, when they were the first ones to actually get working 3D NAND cells on devices, thus hinting at an end of a price war for SSD storage.
This was a very important step in the development of fast storage drives, because stacking the cells in a vertical way enabled more storage at a lower price, the result of which we are enjoying today. This allows even the cheapest of SSDs to have storage sizes up to 2TB, allowing consumers to build computers with fast and reliable storage.
Modern SSDs – They Are Vertically Stacked
Because 3D NAND is so efficient, all manufacturers make their SSDs using vertical stacking. This enables higher storage sizes at lower costs, both for the manufacturers and the end users. Some SSDs are more expensive than others, but that has to do with their NAND cell type, some types being more efficient at read/write tasks, but also a lot more expensive.
The fact is that the best SSD does not really exist in a vacuum, but only the best SSD for the use case and price range. Vertically stacked drives increase the size of storage, but with more bits per NAND cell, the performance worsens, as well as the reliability.
Summary and Conclusion – 3D NAND and V-NAND Are the Same
Marketing terminology has been problematic in the world of technology, anywhere from audio, cameras, to graphics cards, CPUs and in this case, the technology behind SSD storage. V-NAND is Samsung’s name for 3D NAND, where both things refer to the same thing, vertically stacking NAND cells to make better use of a given space on an SSD, be it NVMe or SATA.
Today, most SSDs are vertically stacked to make the largest storage size possible, for consumer applications. Smaller, faster and more expensive drives exist, but those make use of a different type of NAND cell (SLC, for example). These drives are typically used as enterprise solutions, like server drives which require constant read/write access.
For the average consumer, who now knows that V-NAND and 3D NAND mean the same, an affordable, fast SSD will be more than enough for everyday use (unless they are a professional who have frequent read/write uses on an SSD like video editors and audio professionals).
How to Tell if Your Hard Drive is Failing?
Hardware failure can be one of the worst things to happen to an enthusiast, not to mention a professional. Even regular consumers can lose lots of data in the case of a hardware failure. Data is stored on hard drives or more recently, solid-state drives, also known as HDDs and SSDs. Hard drives are the […]
Understanding SD and microSD Card Symbols and Naming Patterns
Naming schemes and patterns are often changed in the world of technology. Some companies and associations like the Wi-Fi Alliance have understood that and named their 802.11 standards as Wi-Fi 1 to 6, retroactively though. Some companies fail to make an understandable pattern of names for their standards or products, leaving consumers more than just […]
Thumb Drive Vs Flash Drive Vs Jump Drive – Aren’t They the Same?
Terminology can be very confusing when it comes to computers. A GPU is not the same as a graphics card, but they are often used interchangeably, and the same can be said for many other terms. When it comes to storage, particularly fast and portable storage, one can without a doubt bump into USB flash […]
MBR Vs GPT – Everything You Need To Know
Installing systems on older computers used to be a challenge, with manual partitioning and a whole shelf of drivers loaded on CDs. More notably, people had even more trouble if they tried to migrate their system to another drive, whereupon data would be lost due to a bad copy. The copy can fail for many […]
What is 3D NAND Flash?
Storage drives have been progressing for the past 70 years, to the point of having massive storage sizes at affordable prices, which are reliable enough for consumer and industrial uses. Storage size, however, is just one parameter that drives needed to meet. Speed became important when CPUs and RAM speeds started increasing, making storage drives […]
What is an EAMR Hard Drive? – What You Need to Know about Modern Storage
When first made, hard drives, or rather, storage devices, were the size of a room. As years went by, storage devices changed shape as well as size, until we reached a couple of standardized formats, namely 3.5 and 2.5 inch hard drives, the former often used for large storage sizes. However, traditional technologies such as […]
