The technology that powers SSDs—NAND flash memory—presents unique challenges, notably in terms of wear and tear due to write and erase cycles. To mitigate these challenges and enhance the longevity and performance of SSDs, two crucial techniques are employed: wear-leveling and over-provisioning. Wear-leveling is a strategy designed to distribute data writes evenly across the memory cells of an SSD, ensuring that no single cell bears excessive wear. This process is key to preventing premature failure and extending the drive’s useful life. Over-provisioning, on the other hand, involves reserving ..read more

SSD overprovisioning refers to allocating extra NAND flash memory beyond the advertised capacity to improve performance and endurance. This reserved space isn’t accessible to the user but is used by the SSD’s controller for wear leveling, garbage collection, and bad block management. By spreading write and erase cycles across more cells, overprovisioning reduces the wear on any single cell, extending the SSD’s lifespan and maintaining its speed over time. An Example: Imagine your SSD is like a bookshelf. Without Over Provisioning, every single shelf is available for you to place your books (or ..read more

In NAND Flash memory, a “block” refers to a group of pages, which are the basic units for reading, writing, and erasing data. NAND Flash memory is organized hierarchically, with the memory array divided into blocks, and each block further divided into pages. The size of a block in NAND Flash can vary depending on the specific type of NAND and the manufacturer, but typically, a block consists of several hundred to a few thousand pages. A page is the smallest unit of data that can be read or written, while a block is the smallest unit that can be erased. Each page typically consists of a few kil ..read more

Do you want to know how long will your SSD Last? Well, I have a great tool for you that will help you do this calculation without the need to know the maths behind it. So, the concept is simple. You just give me the TBW of your drive. You can obviously check that on the manufacturer’s website. Then, you just estimate the daily write amount. If you don’t know, you can just try testing different numbers. Then, this tool will give you the estimated number of lifespan you have with your drive. This is a great tool for those who are too conscious about the TBW and Warranty period of their drives. L ..read more

TBW, standing for Total Bytes Written, is a metric used to estimate the endurance or lifespan of a Solid State Drive (SSD). It quantifies the total amount of data that can be written to the SSD before the NAND flash memory cells begin to wear out to a degree that affects the SSD’s ability to store data reliably. This metric is crucial for understanding the durability and operational lifespan of SSDs, especially in environments with high write demands. When an SSD reaches its TBW (Total Bytes Written) limit, it indicates that the NAND flash memory cells have endured a significant number of writ ..read more

When the throughput of a storage system surpasses its maximum capacity or limits, several issues can arise, impacting performance, reliability, and overall system functionality. The specific consequences depend on the type of storage system (e.g., disk-based, solid-state, cloud storage) and the environment in which it operates (e.g., database systems, file storage, network storage). Here’s an overview of what can happen: Performance Degradation: The most immediate effect of surpassing throughput capacity is a significant slowdown in performance. This can result in longer wait times for data r ..read more

When looking at the SSD specifications, you might have seen the term “NAND Flash” or “NAND Flash Layers”. But, what does that mean? What is it related to? Let me explain this in simple words. Let’s start from the start. The data is stored inside the NAND Flash Memory in the SSDs. This is a type of non-volatile storage technology. “Non-volatile” means it doesn’t need power to maintain the information stored in it. This is different from your computer’s RAM, which loses data when power is turned off. It is mainly used in the devices used for long-term storage. These devices mainly include SSDs ..read more
