How do I fix my wear leveling count?
How Can You Reset “0xAD SSD Wear Leveling Count”?
- Restart the computer, and use combinations of keys shown on the loading screen (they depend on a specific manufacturer, usually “F2” or “Del”) to go to BIOS (or UEFI).
- Go to Аdvanced > SMART settings > SMART self test. Set the value as Disabled.
What is wear leveling count?
Wear leveling is a function that is carried out by most flash memory controllers. The most straightforward approach to wear leveling is to count how many times each block has been erased. When a block is needed to store some data, the empty block with the lowest erase count is used.
What is wear leveling in SSD?
Wear leveling (also written as wear levelling) is a technique for prolonging the service life of some kinds of erasable computer storage media, such as flash memory, which is used in solid-state drives (SSDs) and USB flash drives, and phase-change memory.
What is LBAs written?
5 Answers. 241 – Total LBAs Written: The total number of 512-byte sectors written during the entire lifetime of the device.
What is POR recovery count?
A count of the number of sudden power off cases. If there is a sudden power off, the firmware must recover all of the mapping and user data during the next power on. This is a count of the number of times this has happened.
How is SSD lifespan calculated?
Making the Calculation SSD factor: real amount of data to actual data written = estimate 5 Amount of data written to the drive per year = estimate 1500-2000GB. Using these numbers, your equation will be 3000 (write cycles) x 1000 (GB capacity) / 5 (SSD factor) x 1750 (GB written to drive per year) = 342 years.
Why is there a need for SSD wear leveling?
Wear leveling is needed to address the finite program/erase capability of NAND flash memory cells. When only a limited number of blocks are repeatedly used, the device can prematurely wear out.
Why do SSD wear out?
NAND flash memory is susceptible to wear due to repeated program and erase cycles that are commonly done in data storage applications and systems using Flash Translation Layer (FTL). Constantly programming and erasing to the same memory location eventually wears that portion of memory out and makes it invalid.
Does SSD have longer lifespan?
Among these technologies, the most important is the “wear-leveling” algorithms that effectively make sure all the drive’s memory chips are used up, cell by cell, before the first cell can be written to again. This also means that SSDs of larger capacities generally have longer life spans than do smaller ones.
How do you check how much data was written to SSD?
If you can see how much lifetime data you’ve written on your current SSD, you can estimate its remaining lifespan.
- Install and launch CrystalDiskInfo.
- Look under Health Status.
- Look at the top right for Total Host Writes (or it might just be Host Writes depending on your version).

What’s the endurance of a Samsung SSD 840?
Samsung SSD 840 (250GB) Endurance Testing Total Amount of Data Written 92,623 GiB Total Amount of WLC Exhausted 34 Estimated Total Amount of P/E Cycles 1,064 Estimated Total Write Endurance 272,420 GiB
What’s the wear level on a Samsung SSD?
Samsung doesn’t explicitly expose total NAND writes in its SMART details but we do get a wear level indicator (SMART attribute 177). The wear level indicator starts at 100 and decreases linearly down to 1 from what I can tell.
What does raw wear leveling count on SSD mean?
The raw Wear Leveling Count seems to indicate the amount of exhausted P/E cycles as it’s inversely proportional to the normalized WLC value and once it hits 1,000, the WLC will hit zero.
