Iko kushandiswa kweakasimba-state madhiraivha mumunda wekuchengetedza data hakuchashamisi chero munhu. MaSSD akasimbiswa mumidziyo yeIT, kubva kumakomputa ega uye malaptops kusvika kumaseva uye masisitimu ekuchengetedza data. Munguva ino, zvizvarwa zvakati wandei zveSDD zvachinja, chimwe nechimwe chave chakavandudza hunhu maererano nekuita, kuvimbika uye kugona kukuru. Asi iyo nyaya yekutarisa iyo SSD yekurekodha sosi ichiri yakakosha.
Solid state drives, nekuda kwechimiro chavo chemuviri, vane pre-limited kunyora sosi. Uye chokwadi chekuti data rakawanda rakanyatso kunyorerwa kuSSD pane inotumirwa kwairi nemugamuchiri (kunyanya sechikamu cheboka reRAID) inotiswededza padyo nemuganho wakatarwa. Aya mamiriro imhando yekutya iyo vamwe vashandisi vanayo vasati vashandisa SSDs.
Izvo chaizvoizvo hazvisi zvose zvakaipa. Iyo inofungidzirwa DWPD sosi inopihwa iyo yese waranti nguva yekutyaira (kazhinji makore 3-5). Uye saka, iyo chaiyo TBW yekurekodha sosi ichave inonakidza, iyo inobvumidza iwe kuti usatya "kudzima" iyo SSD mumwedzi mishoma. Uyezve, mune zvimwe zviitiko zvinokwanisika kushandisa kwechinguva madhiraivha mune yakanyanya kuomesesa modhi pane yakapihwa nemugadziri chaizvo nekuda kweiyo yakakwira TBW tsika. Nekudaro, zvese izvi hazvibvisi kudiwa kwekutarisa yazvino yekurekodha sosi yega yega yega SSD nechinangwa chekutsiva chinobatika kana mamwe maburi asvikwa.
Mutengesi wega wega wekuchengetera anoita basa iri nenzira yake. Asi kazhinji ichi chingori chakanaka / chinokanganisa drive chivakwa. mune yavo , pane zvinopesana, yakaita chitarisiko chakakwana chezviyero zvezvino SSD chiitiko muchimiro cheimwe module inonzi QSLife. Iyi module chikamu chakakosha cheiyo nyowani yekushandisa system , pasi payo ese maQsan ekuchengetedza masisitimu achashanda mune ramangwana.
Kune imwe neimwe SSD muhurongwa, ikozvino "chiyero chekurarama" chinoratidzwa mune iyo inonyanya kuwanikwa fomu. Haisi chakavanzika kuti ese emazuvano maSSD anochengeta marekodhi avo ezvivharo zvakanyorerwa kwavari. Zvichienderana nehunhu uhwu, sisitimu inoverengera chiratidziro chekupfeka chinoenderana nemakaki ayo. Mhedzisiro yekupedzisira inoratidzwa sechikamu cheiyo SSD nyowani. Isu tinocherekedza zvakare kuti dhigirii rekupfeka rinoverengerwa kwete chete kwenguva yenguva iyo drive yakashanda sechikamu cheAll Flash Qsan array, asi kwehupenyu hwayo hwese, kusanganisira basa sechikamu chemamwe masisitimu (kana aripo).
Pamusoro peruzivo rwakareruka nezve dhiraivha, iwe unogona zvakare kuwana mamwe ruzivo. Kunyanya, huwandu hwe data yakanyorwa pairi pamusoro pehupenyu hwayo hwose hwebasa. Uye panguva iyo drive yakashanda sechikamu che , magirafu ekushanda kwayo mumabasa ekuverenga nekunyora aripo. Nhamba dzinounganidzwa munguva chaiyo uye dzinowanikwa chero nguva ine hudzamu hwekutarisa hunosvika gore rimwe.
Ehezve, chinangwa chekushanda uku hakusi chete kuvaka magirafu akanaka kuti afadze maneja, asi zvakare kunyatsoongorora mamiriro emadhiraivha uye kudzivirira matambudziko anogona kuitika mune ramangwana ane chekuita nekupfeka kwavo uye kubvarura. Naizvozvo, maererano ne "chiyero chehupenyu" cheSSD, unogona kuseta akawanda maburi uye zviito zvinoenderana zvine chekuita nekuneta kweiyo SSD yekurekodha sosi.
Kana iwe ukatarisa mamwe masisitimu ekuchengetedza masisitimu (kwete nyanzvi Yese Flash, asi chinangwa chakajairika) , saka ivo havana mushumo wakadaro unooneka pamadhiraivha. Izvi zvinonzwisisika: mushure mezvose, iyo mureza inofanira kunge yakasiyana kubva kune yakawanda. Nekudaro, kutarisa kwakafanana kunodiwa kune yakajairika chigadzirwa mutsara. Hongu, pasina kuunganidza mashandisirwo uye maitiro ehuwandu. Asi basa guru rekutarisa chinyorwa chekurekodha chiripo.
Nekuda kwekugara kuvandudzwa kweiyo solid-state drive kugadzira matekinoroji, mubvunzo wekuvimbika kwavo wakambodzikira. Asi, zvisinei, kutarisa sosi yekurekodha kwavo kuchiri kukosha. Kutarisisa kwakanyatso kurongeka kunobvumira maneja kufanotaura kuchembera kweSSD pachine nguva maererano nemitoro chaiyo iripo, uye manejimendi ekambani kuverenga TCO (yakazara mutengo wevaridzi) zviratidzo.
