Then divide that value against the number of years you have been using this drive so far. In order to find WRL value you may need to run this command in the terminal smartctl -x disk0 and find Data units read/ write values that you can combine. Half-day power on value would be around 4365. If you do shut down your drives, check the total power-on value and divide that against the years you have been using this drive (or how many hours per year you plan on using it). If your drives do an automated daily shutdown then this value will be unique. If you run an HDD SMART test, you will be also able to find Power on hours. Assuming the user spends several hours per day working with large files, this could result in an average of around 328 HDD load/unload cycles per day. These files can require frequent access to the hard drive to load and save data, which could result in a higher load/unload cycle count. A user who regularly works with large files, such as high-resolution images and video.Assuming the user spends a few hours per day streaming and downloading media content, this could result in an average of around 328 HDD load/unload cycles per day. Streaming services and media players often require frequent access to the hard drive to buffer and play content, which could result in a higher load/unload cycle count. A user who frequently downloads and streams media content, such as music, movies, and TV shows.Assuming the user plays games for a few hours each day, this could result in an average of around 328 HDD load/unload cycles per day. Many modern games require frequent access to the hard drive to load new levels and assets, which could result in a higher load/unload cycle count. A user who regularly plays video games on their computer.Assuming the user spends several hours per day on their computer, and regularly saves and opens documents, this could result in an average of around 328 HDD load/unload cycles per day. A user who frequently accesses their computer for work purposes, such as writing and editing documents, sending emails, and browsing the internet.Here are a few use-case scenarios that could result in an average of 328 HDD load/unload cycles per day: Or if this is your first data storage device, you can use this average use estimate table.Įxpected Load/Unload Cycles in different environments Use Caseġ,200,000 – 1,500,000 (1000 cycles per day) 600 total cycles divided by 2 years since the use of this drive). Divide that figure to find out an average yearly use (e.g. You can make an educated guess from the existing drives you are using. The MTBF value can be found on the PDF spec sheet that HDD manufacturers publish for every drive. MTBF Load/Unload cycles per day WRL per Year ON hours per day CALCULATE
