Samsung SSD 840 Pro

Minap ránéztem az SSD-re, és a következőt láttam:

Kérdésem, hogy kinek mi a véleménye?
Túl sűrűn használom, hamar el fog kopni, ha idő előtt (garancia) elkopik fogják-e nekem cserélni?
Ha jól emlékszem idén július óta van.

Ha nem lenne egy a színes, szagos bohócruha (Merevlemez Őrszem), hanem egy egyszerű SMART diag kimenet, még talán valami értelmeset is lehetne mondani.

Teljesen jogos! :)
Remélem így kicsit többet tudok mutatni:

Na nézzük:

"ID # 177 Wear Leveling Count

This attribute represents the number of media program and erase operations (the number of times a block has been erased). This value is directly related to the lifetime of the SSD. The raw value of this attribute shows the total count of P/E Cycles."

A Pro MLC-s. Az MLC-k (függően a gyártástechnológiától) 3000-5000 P/E ciklust bírnak (a TLC-k nagyjából 1000-et, az SLC-k 100 ezret). Te most 38-nál tartasz. 3000-rel számolva az kb. 98%-os (ezt írta az őrszem is).

Nem hiszem, hogy szarnod kéne ettől.

A 240gb-s ocz vertex 3-asom a drivedx szerint 57.1%-os, 11.2 terát írtam már rá, 8884 órát volt eddig használva trim nélkül és még mindig nem vettem észre semmi lassulást.

Lol @sok írás.

Én fél év alatt legalább 200 P/E cycle-t tettem bele. Melós gép, sokat fordítok rajta, amúgy a written LBAs nem magas, de a sok kis fájl miatt a write amplification 10x-es.
A jenkins slave-eink alatt az SSD-k kb 3 hónap alatt 600 cycle-t szedtek össze. Na EZ sok írás, nem a félév alatt 38.
