Windows 7: Limited write cycles to SSD?

Limited write cycles to SSD?

Hi all :)

I keep hearing about how there is a limited amount of times that an SSD can be written to. I have recently purchased an M2 NVMe SSD, and have emailed Samsung asking about this, but have yet to hear back.

Is what I hear correct? If so, how does one find out what the #s are? A google of samsung 970 evo write cycles didn't reveal anything of use.

Thanks in advance.

Hi,

The answer you seek kind of depends on the NAND technology used. Personally, I do not know this answer. You could try Searching the Web for "Samsung V-NAND 3-bit MLC", and see what kind of endurance measures and recommendations you receive.

Any SSD has a flash memory and it DOES has a limit write cycles. When a cluster is failing it will mark as bad and use another one.

What is SSD write cycle? - Definition from WhatIs.com
The number of write cycles, or endurance, varies based on the type of NAND flash memory cell. An SSD that stores a single data bit per cell, known as single-level cell (SLC) NAND flash, can typically support up to 100,000 write cycles. An SSD that stores two bits of data per cell, commonly referred to as multi-level cell (MLC) flash, generally sustains up to 10,000 write cycles with planar NAND and up to 35,000 write cycles with 3D NAND. The endurance of SSDs that store three bits of data per cell, called triple-level cell (TLC) flash, can be as low as 300 write cycles with planar NAND and as high as 3,000 write cycles with 3D NAND. The latest quadruple-level cell (QLC) NAND will likely support a maximum of 1,000 write cycles.

As you have a desktop, you can use a HDD to:
- Install software that is daily updated, like antivirus
- Move the virtual memory to the HDD.
- Move the temp folder to the HDD.
- Move C:\Users to D:\Users (all data will be on the HDD and more important "Name\AppData\Local\Temp" that has all trash will also be on the HDD). Use Kari tutorial to move C:\Users to D:\Users.

I have a small M.2 PCIe SSD (128G) for windows & programs (85G) and Linux (40G) and a HDD for data.
It has the speed of a SSD and the size of a HDD at low cost.



I can guide you on.

here are specs for 970 EVO Samsung SSD 970 EVO | Samsung V-NAND Consumer SSD | Samsung Semiconductor Global Website
Samsung warranty is for 150TB writes on 250GB SSD, 300TB on 500GB and up to 1200TB on 2TB SSD. In real life tests usually SSD drives survived x4 to x8 warranty numbers before actually failing. It would be rather difficult for casual pc user to reach those write cycle limits even in 20 years, your computer will fail and become obsolete much sooner than that. There are many programs that can read write cycles on SSD, I use portable app called CrystalDiskInfo

SSD Endurance is commonly measured and specified by manufacturers in TBW ( Tera Bytes Written - how much you can write cumulatively into the drive over its lifetime).

For example SAMSUNG rants that its 860 EVO 500GB SSD using "the latest V-NAND technology gives you up to 2,400 TBW, or is backed by a 5-year limited warranty" ( MZ-76E500BW (500 GB) 5 Years or 300 TBW)

Crystal Disk info can give you information on Total writes in your SSD.

[ SSD endurance may also be indicated in Drive Writes Per Day (DWPD) - how many times you could overwrite the drive’s entire size each day of its life.]

Hey - thanks so much for the info and links!

So, it appears as the amount you can write to the drive is based on the amount of data; not the amount of times data is written to the drive.

I thought that there is a limited amount of "write cycles", and that each time data is written to the drive, regardless of file location, type and size, that counted as one write cycle towards the total. Meaning that every time I visit a website and a cookie is placed in the cookie's folder, that was one write cycle. If I activated a plugin in my DAW, and my vstpluginfo.xml would get overwritten, that was another write cycle. But this appears to not be the case.

Will check out crystaldisk.

Cheers.
