When we want to meet all information about our hard drive or SSDno doubt Crystaldisk Details This is one of the best tools we can use. But you know what do all the parameters mean what does it give us? In this article we will explain you in detail so you can understand them and be able to explain them properly, so that you know the exact state of your drive or SSD.
CrystalDisk Info is a free tool that you can download from many online articles, too compatible and many functional programs as well all hard drives and SSDs on the market, including the latest NVMe PCIe 4.0 SSDs.
Basic disk or SSD details
At the top, what it tells us is the name of the disk, as written by the manufacturer in its firmware. This name, as in the case of our example, can be your SKU or model number simply. On the right hand side of the word has the received volume (which does not have to match that advertised by the manufacturer).
Let's take a look at all the parameters for this high-level, basic information.
- Firmware: The firmware number you entered. So, we can compare this newest version and see if we should update or not.
- Serial number: device serial number.
- Agreement: Here it tells us how it is connected to a PC. For example it is NVM Express, but if it's a SATA disk, it will tell us about the serial ATA, etc.
- Transmission mode: This parameter indicates the relative compatibility with the one you are using. In this example they are both PCIe 3.0 x4, but if we had a PCIe 4.0 SSD connected to a PCIe 3.0 socket, we would see it here.
- The Drive Book: book you've shared
- Normal: associated standards. If disk were SATA, we would say with ACS-2 for example.
- Supported features: Parameters such as S.M.A.R.T., APM, NCQ, TRIM and DevS sleep will be shown here.
- Total Readers Writers / Writers: number of readings and unit texts. For example, 4141 GB is written to calculate disk data in TBW. This data is very interesting to know the remaining life of SSD.
- Rotation speed: This data shows high RPM disk, if it is a mehendi disk. In the case of SSDs it has no rotation.
- No.: number of times the phone is turned on.
- Time is on: number of hours the device was on. If you leave a mouse on it tells you to translate it into days.
Of course, on the left side we can also see the health status achieved by CrystalDisk Info (be careful because this depends only on the error rate and the bad sectors) and temperature just below.
Advanced CrystalDisk Info
The site below provides us with a series of additional technical and advanced information, which, in some cases, may not be useful (but for many others, especially if we have a problem with the device). Let's look only at the most interesting and relevant, because the parameters shown here depend on what the author wrote in the firmware.
- Unexpected Power Loss: This parameter will tell us how many times the device has lost electricity incorrectly.
- Heat: the temperature anyway.
- Duration of Total Length / Read: amount of data that is written and read in memory cells, expressed in GB.
- SSD health Left: average in the hours of life left by SSD
