How to calculate the TBW (Terabyte Writes ) for SSD drive?

Image
Here is the formula for calculating the TBW (Terabyte Writes ) of SSD drive: 1, As know that there is a OP zone (Over-provisioning) in a SSD drive, it takes about 7% of the capacity, so the real capacity you could use is about 93%. 2,  P/E cycles (write cycles) , depending on the Nand flash type of your SSD, and according to the newest process of Nand, their P/E cycles are as following: SLC: ≈ 60,000 MLC: ≈3,000 TLC: ≈1,000 3, WAF (Write amplification) , the perfect WAF is 1, but actually there is no SSD supplier can achieve their WAF to "1" , there are many factors affect the WAF, usually we calculate with 1.5 times. Then, it's easy for you to calculate the lifetime (how many years you can use) for your SSD drive:   Lifetime (years) = (TBW / Workload) / 365 *Workload: total GB written per day

SSD Bad Block Management

SSD Bad Block Management How does bad block occur? And by what means does the SSD detect and manage bad blocks? What are the problems for the bad block management strategy proposed by the manufacturer? And what kind of management method is more superior? Does disk format lead to loss of the bad block list?  What potential risks may be caused by maintenance of the SSD? This article will help you uncover these secrets. Overview The design concept about bad block management concerns the reliability and efficiency of the SSD. While the bad block management methods offered by some SSD vendors are not always so reasonable, it will cause unexpected bad blocks if some abnormal conditions haven't been considered comprehensively during the product design process. E.g, after testing several SSDs with different controllers, we found that new bad blocks caused by abnormal power failure are very common. When we google “bad blocks by power failure” or similar keywords, we wil...
