You might be wondering what happens to an SSD after it reaches its advertised Terabyte Written limit. Obviously, it is not going to die immediately as soon as it hits the limit. Because a lot of times, the terabyte written aspects is the warrantied durability, so that’s the amou...
The fact that NAND SSD has a write-cycle limit suggests that database administration could be adjusted to accommodate this characteristic. If there were some means of determining that an SSD is near the write-cyle limit, active data could be migrated off, and the SSD could be assigned to ...
SS: Sample Size,就是我们要求的X (用多少块盘测试) UCL(): Upper confidence Limit函数,看不懂是不是,不用你看懂,直接查表就行。 通常我们直接用AL=0(AL=0代表没有functional failure),这样的话对应的UCL就是0.92。 结合一个实际的例子, FFR=3%, UBER=10-16, TBW=100代入公式,得到: SS ≥ 0.92/(0...

You’d have to work hard to reach the P/E cycle limit for an MLC-based drive, let alone an SLC-based one. Nevertheless, every time you write something to the drive, you bring it a little closer to its demise. Don’t obsess over every single write cycle—a few of our later tips ...
As discussed in Section 1.1, NAND-flash cells have a limited lifespan due to their limited number of P/E cycles. Let’s imagine that we had an hypothetical SSD in which data was always read and written from the same exact block. This block would quickly exceed its P/E cycle limit, we...

Because NAND-flash cells are wearing off, one of the main goals of the FTL is to distribute the work among cells as evenly as possible so that blocks will reach their P/E cycle limit and wear off at the same time. 由于NAND闪存单元正在磨损,FTL的主要目标之一是尽可能均匀地在单元之间分...
Direct method,简单来说,就是使劲写,可劲读,用站在食物链顶端的男人的话说就是”Push the SSD to limit”,在这个过程中,要注意: 要求有高低温 必须用指定的workload Endurance test以后马上Retention test 这些个后面详细介绍,首先要搞明白一个问题,应该拿多少块SSD跑Endurance测试?
