Per determinare sommariamente le performance di un disco in linux si può far ricorso all’ utility Benchmark presente nel programma Gnome Disks. Il programma è conosciuto anche con il nome Gnome Disk Utility.
Il programma può essere installato in Debian con il comando
apt install gnome-disk-utility
Il test di Benchmark evidenzia 3 parametri:
- velocità di scrittura
- velocità di lettura
- tempo medio di accesso
Si tratta di un test du bencmark sommario che non offre molte opzioni. Ad esempio campioni dei file non possono essere inferiori ad 1.0 MB.
Di seguito i tests di varie unità di memorizzazione sia SSD che di tipo tradizionale con dischi magnetici da 3.5″ e 2.5″.
Il test come anticipato è eseguito, in genere, con lo stesso computer. Il sistema operativo è debian 9.0.
Le impostazioni sono quelle di default 100 files utilizzati per la lettura altrettanti per scrittura 1000 per il tempo di accesso il file è stato impostato ad 1 MB.
