Nowadays on Windows, removing hot USB (USB drives) or portable storage devices such as external hard drives often contains the risk of data loss or damage, worse than corrupting USB devices if removed. forgot to click the Safely Remove icon. On Windows 10, this problem has been improved by Microsoft, from the October 2018 update of 1809. This change is as follows:
Microsoft has changed the management mechanism for Windows 10 USB devices in Windows 10. You can right-click on the Start Menu button select Disk Management, right-click the USB storage drive (right above the Disk letter, not the partition name)> select Properties > select the card PoliciesIn the Polcies tab, Removal policy has 2 options Quick removal (default) ie has been turned on by default and Better performance.
When Quick removal mode is selected, external devices can be hot-swapped without going through the procedure of pressing Safely Remove Hardware and then Eject. So you can freely remove the device, without thinking much, but this mode also has the disadvantage that it disables the write buffer feature. In terms of transmission speed, it may not be affected much, but when the heater is removed, the data may be damaged.
So Better performance is different? In this mode, Windows will manage the data transferred back and forth between the device and the external device to optimize performance. This management includes data buffering while being transmitted, being opened or being prepared for certain tasks. Whether the external storage device is always ready to respond means that if you want to remove it, you have to take steps Safely Remove Hardware and then press Eject manually. Processes will be disconnected and the USB device is safe to remove.
Quick removal (left) and Better performance.
Quick removal took 1 minute 44 seconds and Better performance took 1 minute 45 seconds – this is the result of a stopwatch that I tried to copy an ISO file of more than 4 GB from the Micron 2200 256 GB NVMe SSD in the device to the attached hard drive. External is Hitachi 750 GB 7200 rpm. There is a difference that I realize is that a more stable transfer rate with brother charts can be almost flat in Better performance mode while Quick removal is a bit more slippery.
Similar to a LoL 9.4 GB game folder with many small files copied from the Micron SSD to ADATA's USB 3.0 64 GB, these two modes take 4 minutes 45 seconds to complete, Better mode performance is faster than a few seconds, but what I have noticed is that the transfer rate is better than Quick removal mode, less slippery.
According to Microsoft, Windows will optimize the read and write operations, ensure data integrity so I think with the storage devices that contain important data, you should turn on Better performance mode and remove the device via Safely Remove Hardware process to minimize the risk of data damage. Particularly for the type of data is not very important and especially you have the habit of removing USB hot, just to Quick removal.
Need also note The change between these two modes will apply to each storage device, not the entire system. So for each device you plug into the computer, you want to switch, then go to Disk Management and manually switch each device.
