Ukusetshenziswa kwamadrayivu e-solid-state emkhakheni wokugcinwa kwedatha ngeke kusamangaza noma ubani. Ama-SSD aqiniswe emishinini ye-IT, kusukela kumakhompyutha omuntu siqu namakhompyutha aphathekayo kuya kumaseva nezinhlelo zokugcina idatha. Ngalesi sikhathi, izizukulwane eziningana zama-SSD zishintshile, ngasinye esinezimpawu ezithuthukisiwe ngokusebenza, ukwethembeka kanye nomthamo omkhulu. Kodwa indaba yokuqapha insiza yokuqopha ye-SSD isabalulekile.
Amadrayivu wesimo esiqinile, ngenxa yesakhiwo sawo somzimba, anensiza yokubhala elinganiselwe ngaphambili. Futhi iqiniso lokuthi idatha eningi empeleni ibhalelwe i-SSD kunaleyo ethunyelwa kuyo umsingathi (ikakhulukazi njengengxenye yeqembu le-RAID) isisondeza nakakhulu emkhawulweni omisiwe. Lesi simo siwuhlobo lokwesaba abanye abasebenzisi ababa nalo ngaphambi kokusebenzisa ama-SSD.
Empeleni akukubi kangako. Insiza ye-DWPD elinganiselwe inikezwa sonke isikhathi sewaranti yokushayela (imvamisa iminyaka emi-3-5). Ngakho-ke, insiza yokurekhoda ye-TBW yangempela izoba umxhwele kakhulu, okuvumela ukuthi ungesabi "ukusula" i-SSD ezinyangeni ezimbalwa nje. Ngaphezu kwalokho, kwezinye izimo kungenzeka ukusebenzisa okwesikhashana amadrayivu kumodi ejulile kunaleyo enikezwe umenzi ngokuqondile ngenxa yamanani aphezulu e-TBW. Kodwa-ke, konke lokhu akusiqedi isidingo sokuqapha insiza yokurekhoda yamanje ye-SSD ethile ethile ngenjongo yokushintshwa okusebenzayo lapho kufinyelelwa imingcele ethile.
Umthengisi ngamunye wesitoreji usebenzisa lokhu kusebenza ngendlela yakhe. Kodwa ngokuvamile lokhu kumane nje kuyimpahla yokushayela enhle/enephutha. kwezabo , ngokuphambene nalokho, wenze ukubonakala okuphelele kwemingcele yomsebenzi wamanje we-SSD ngendlela yemodyuli ehlukile ebizwa ngokuthi i-QSLife. Le mojula iyingxenye ebalulekile yesistimu yokusebenza entsha , lapho zonke izinhlelo zokugcina ze-Qsan zizosebenza ngaphansi kwazo ngokuzayo.
Ku-SSD ngayinye ohlelweni, "izinga lokuphila" lamanje liboniswa ngendlela efinyeleleka kakhulu. Akuyona imfihlo ukuthi wonke ama-SSD anamuhla agcina amarekhodi awo amabhulokhi abhalelwe wona. Ngokusekelwe kulawa manani, isistimu ibala inkomba yokuguga kwedrayivu ngokuhambisana nezimpawu zayo. Umphumela wokugcina uboniswa njengephesenti le-SSD entsha ngokuphelele. Futhi qaphela ukuthi izinga lokuguga alibalwa kuphela ngesikhathi idrayivu esebenze njengengxenye ye-All Flash Qsan yamalungu afanayo, kodwa kuyo yonke impilo yayo, okuhlanganisa umsebenzi njengengxenye yezinye izinhlelo (uma ikhona).
Ngaphezu kolwazi olwenziwe lula mayelana nedrayivu, ungathola futhi imininingwane ethile. Ikakhulukazi, inani ledatha erekhodiwe kuyo yonke impilo yayo yesevisi. Futhi phakathi nesikhathi lapho idrayivu isebenze njengengxenye ye , amagrafu okusebenza kwawo ekusebenzeni kokufunda nokubhala ayatholakala. Izibalo ziqoqwa ngesikhathi sangempela futhi zitholakala nganoma yisiphi isikhathi ngokujula kokubuka okungafika onyakeni owodwa.
Yiqiniso, inhloso yalokhu kusebenza akukhona nje ukwakha amagrafu amahle ukuze kujabulise umlawuli, kodwa futhi ukuhlaziya ngokucophelela isimo sokushayela nokuvimbela izinkinga ezingase zibe khona esikhathini esizayo ezihlobene nokuguga kwazo. Ngakho-ke, maqondana "nezinga lokuphila" le-SSD, ungabeka imingcele eminingi nezenzo ezihambisanayo ezihlobene nokukhathala kwensiza yokurekhoda ye-SSD.
Uma ubheka amanye amamodeli wesistimu yesitoreji (hhayi okukhethekile kwe-All Flash, kodwa inhloso evamile) , bese bengenayo umbiko onjalo obonisiwe kumadrayivu. Lokhu kuyaqondakala: ngemva kwakho konke, i-flagship kufanele ihluke ngandlela-thile kokuvamile. Nokho, ukuqapha okufanayo kuyadingeka emugqeni womkhiqizo ojwayelekile. Yebo, ngaphandle kokuqoqa izibalo zokusetshenziswa nokusebenza. Kodwa umsebenzi oyinhloko wokuqapha insiza yokuqopha ukhona.
Ngenxa yokuthuthukiswa okuqhubekayo kobuchwepheshe bokukhiqiza idrayivu ye-solid-state, umbuzo wokuthembeka kwabo usuhlile kancane. Kodwa, nokho, ukuqapha insiza yokuqopha kwabo kusabalulekile. Ukuqapha okunjalo okulungiselelwe kahle kuzovumela umlawuli ukuthi abikezele ukuguga kwe-SSD kusengaphambili ngokuhambisana nemithwalo yamanje yangempela, futhi abaphathi benkampani ukubala izinkomba ze-TCO (ingqikithi yezindleko zobunikazi).
