Sharing Experiences in Testing Solid State Drives SSD
I believe that many people have used SSDs, but for SSDs, many people will be confused about lifespan. In fact, SSDs don't have to care about maintenance. life, but because some people care, today U Hero will share with you some ways to check life of SSDs.
Many hard drive tools, especially for solid state drives, have a lifetime feature, such as widely used CrystalDiskInfo hard drive lifetime tool. The method to determine life of software is very simple, run program directly, let's test some Intel SSD A, and then you will see corresponding parameters of hard disk, there is a degree of health, and degree of health indicates remaining life of SSD.
Supplier Tools #2
The lifetime of SSDs as detected by various hard drive detection tools can vary or even be relatively long. For example, we used Intel SSD Toolkit to detect and see that lifetime value is only 67 years. %.
SSD Test #3M.2
Because SSD tested above is not an NVMe SSD, there is a problem that detection time is too long. We can then test Toshiba NVMe SSD. For hard disk, you can see that its health is 100%. This health is determined by 03 Available Spare parameter in list below, that is, available free space.
Of course, Toshiba also has its own SSD testing tool, which is Toshiba SSD Utility. With this tool, you can check that health of this hard drive is 97%. Numerically, one is 100% and other is 97%, which should be more accurate, but this is actually biggest difference. The 97% value is based on percentage of host writes relative to total writes (TBW) of calibrated by manufacturer of SSD, which is numbered 05 in the above list.
So, from above two examples, it can be seen that different SSD detection tools not only determine different lifetime, but even for homogeneous standard NVMe SSD hard drives, different tools calculate lifetime according to different calculation methods. So, which one of them is more accurate?
Actually, SSD detection tool provided by manufacturer is more accurate and relatively scientific. Using percentage calculation based on fixed TBW is tough but much more reliable than life prediction based on spare unit consumption. Therefore, if you are worried about lifespan of an SSD in future, you only need to go to official website of respective brand to download testing tool provided by the manufacturer for testing.
