Jen tak ze zvědavosti by mě zajímalo, kolik jsem celkově za dobu od koupi SSD disku (6 let) zapsal dat, existuje nějaký jednoduchý příkaz či nástroj jak to zjistit?
-
Utilita výrobce disku. Ale drtivá většina jich běží pod win nebo z boot media. Můžeš nabootovat třeba ubcd kde v sekci hdd/diagnosis se můžeš "vyřádit".
Pro linux existuje http://wiki.ubuntu.cz/smartmontools případně GUI gsmartcontrol
sudo apt-get install gsmartcontrol
Nejpodrobnější výpis získáš příkazem:
sudo smartctl --xall /dev/sdX
(za "X" dosaď písmeno disku)
------------------------
Některé utility udávají životnost disku, např. 50% Tato hodnota se vztahuje k TBW udávanému výrobcem ve specifikaci. Z těchto dvou údajů pak snadno spočítáš kolik dat bylo zapsáno.

To asi není to číslo které hledám, že?

a jelikož má jeden logický sektor 512 bytes, Zbytek už si snad dopočítáš sám. Doufám, že neshoříš na přepočtu jednotek... http://extraconversion.com/data-storage/bytes/bytes-to-terabytes.html
Ale jelikož s tím spousta lidí zápasí, raději ti to spočtu sám viz obrázek.

Děkuji. Proč je přepočet do TiB namísto TB?
Nějaký zdorj uvádí životnost M500 je 72TB takže po 6 ti letech mám ještě cca 80% životnosti SSD, to se mi zdá moc pěkný.
Trochu mě děsí crystalidisk info, který říká, že po necelém měsíci používání "Samsung mzvlw256" mám zapsáno "total host writes" 832GB dat, to se mi zdá docela dost, když vezmu žě jsem 1x reinstaloval windows10 a 3x instaloval Ubuntu.

Je všeobecně známo, že Windows počítají data správně v GiB (TiB) ale nesprávně to označují jako GB (TB). Takže v "tento počítač" vidíš sice napsané GB, ale ve skutečnosti to jsou GiB...
V Ubuntu to každá aplikace udává jinak (některé v GiB - třeba GParted, jiné v GB - třeba Sledování systému), ale označené je to zpravidla správně.
Jinak přepočet je 1GB = 0.931 GiB takže údaj v GB je vždy větší.
-----------------------------------------------------------------------------------------
832GB za měsíc je dost, průměr bývá cca třetinový....
