Dobrý den, chci se zeptat jak zjistit životnost SSD disku ?
Díky za odpovědi.
-
Co tym myslis?
http://diit.cz/clanek/ssd-deep-hell-6
Alebo hladas program na zistenie stavu disku?
-
ano, program, ale bohužel program SSDlife nemůže v pc najít žádné SSD a crystaldisk když otevřu tak taky nenajde žádný disk.
-
Tak vyrobce SSD by me mit v dokumentaci disku zaruku kolik lze zapsat dat, a aktualni hodnota de pak zjistit ve SMARTu, tedy konkretne ume sem si musel nainstalovat GSmartControl, hodnota Total_LBAs_Written po vynasobeni LBA velikosti tedy u me konkretne 512, by melo davat hodnotu kolik na disk bylo celkem zapsano v bajtech, tam de zjisit dalsi udaj pouzivany k zhodnoceni zivotnosti a to Wear_Leveling_Count cim min tim lip, 100 je maximum, postupem casu by sem melo normalne zvysovat opotrebenim disku.
-
Osobne ssd nemam ale aplikacia gnome-disks v smast casti neukazuje aj opotrebovanost ssd disku?
-
Wear_Leveling_Count jo, ale ne Total_LBAs_Written a Power Recovery Count(235)

Já používám smartmontools. V terminálu pro zjištění stavu disku pak zadat:
sudo smartctl -a /dev/sda(pro výpis disku /dev/sda)
tady je na ukázku malá část výpisu mého SSD, to Lifetime Writes by mělo odpovídat Total_LBAs_Written
231 SSD_Life_Left 0x0013 096 096 010 Pre-fail Always - 0
233 SandForce_Internal 0x0000 000 000 000 Old_age Offline - 7971
234 SandForce_Internal 0x0032 000 000 000 Old_age Always - 5032
241 Lifetime_Writes_GiB 0x0032 000 000 000 Old_age Always - 5032
242 Lifetime_Reads_GiB 0x0032 000 000 000 Old_age Always - 5278

GSmartControl je samozrejme graficka nadstavba smartctl, primo smartctl pouzivam nato, abych mel hodnotu Total_LBAs_Written prepocitanou na MiB v Conky.

no tak teda nevím, nějak se v tom nemůžu vyznat, ale něco mi říká že je něco špatně ...
zde je výpis

Tole ale s Ubuntu nema nic spolecneho, stim zajdi na nejake forum o hardware, kde ti analizuji vypis ze SMARTu.
-
To je dle technologie, jak se ukládaj data(firmware), typu paměťovýho čipu, který má též různé metody, jak ukládat jendičky a nuly(SLC,MLC ...) a technologie, jakou jsou čipy vyrobeny v nanometrech(teoreticky čím modernější, tím míň přepisů).
Občas mrknu na různá SSD a pokud nekoupíš vyloženě nějaké šméčko(Kingston některé apod), tak jsem počítal životnost na kalkulačce i co hlásili programy, tak SSD, co jsou staré 2-3roky, hlásili životnost ještě 7-9let. A to své vůbec nešetřím. Kdepak nějaká komprimace dat on tle fly... mám ho skoro plné, denně ho přelívám a drží.
-
dobrá takže životnost SSD nebudu řešit a v klidu pojedu dál .
Díky všem za rady.
-
Taky bych to nedramatizoval. SSD vetsine uzivatelum prestane moralne dostacovat, nez by klekl fyzicky.
