Model Family: Toshiba L200 (SMR)
I would not consider a HDD with shingled magnetic recording as a storage to install OS. This series has a CMR product, but it has another problem:
3 Spin_Up_Time POS--K 100 100 001 - 1318 4 Start_Stop_Count -O--CK 100 100 000 - 606 193 Load_Cycle_Count -O--CK 093 093 000 - 75472
It has quite aggressive policy to unload heads. It happens approximately than once per minute. Following read operations may have noticeable delay. At first I suspected delays due time required to spin up stopped disk, but in your case Power_Cycle_Count = Start_Stop_Count, so your system keeps the disk spinning.
191 G-Sense_Error_Rate -O--CK 100 100 000 - 48930
Frequent shocks, vibration, unstable base may force heads unloading and following latency in UI.
P.S. I have not managed to change heads unload timeout for Toshiba L200 using hdparm. In your case due to high G-Sense_Error_Rate increasing timeout might be dangerous.
