I have a Samsung 960 Pro SSD with Ubuntu 18.04
is it safe to put the swap file on there or would it hurt it in the long run,
I heard some people saying that new SSDs don't suffer from that issue anymore, is this true?
I have the exact same SSD w/512 GB and Ubuntu 16.04 setup an GB SWAP partition on it. I see no problem because:
First step is to install
nvme-cli because it provides the most information:
sudo apt install nvme-cli
Next gather information available from SSD:
$ sudo nvme smart-log /dev/nvme0 Smart Log for NVME device:nvme0 namespace-id:ffffffff critical_warning : 0 temperature : 36 C available_spare : 100% available_spare_threshold : 10% percentage_used : 0% data_units_read : 8,743,226 data_units_written : 4,763,574 host_read_commands : 147,308,749 host_write_commands : 47,032,599 controller_busy_time : 343 power_cycles : 519 power_on_hours : 376 unsafe_shutdowns : 66 media_errors : 0 num_err_log_entries : 198 Warning Temperature Time : 0 Critical Composite Temperature Time : 0 Temperature Sensor 1 : 36 C Temperature Sensor 2 : 43 C Temperature Sensor 3 : 0 C Temperature Sensor 4 : 0 C Temperature Sensor 5 : 0 C Temperature Sensor 6 : 0 C Temperature Sensor 7 : 0 C Temperature Sensor 8 : 0 C
The most important field is
Percentage used which shows as 0%. This isn't disk usage percent but life used percent. I've had this drive since October 2017 and now it's May 2018. As soon as
Percentage used hits 1% I can multiply the number of months I've owned it by 100 to find out when it will die. But they say the drive typically lives longer than that.
