Iidrayivu ezilukhuni ze-SSD sisixhobo sehardware esingasiboni ngokwasemzimbeni kodwa esisetyenziselwa ukugcina umxholo wazo zonke iintlobo. Ngaphandle kwezi I-SSD kwisicatshulwa sayo iyahambelana Idiski kaRhulumente eSolid izixhobo zethu ziya kufuna ezinye izinto zokugcina iifoto, umculo, iifayile, amaxwebhu kunye nokunye.
Namhlanje sifuna ukwabelana nawe 5 amaqhosha ale SSD hard drive ukuze uyiqonde kwaye ngaphezu kwayo yonke into oyaziyo ukubaluleka abanalo ngaphakathi naliphi na iqela namhlanje. Ngaphandle kwee-SSDs kunokuba nzima ukugcina lonke ulwazi esinalo namhlanje.
Ngaphandle kwamathandabuzo sinokuthi i-SSD yePC yethu okanye iMac yenye yezona ndawo zibalulekileyo zekhompyuter, zikwifowuni ye-smartphone okanye yomdlalo weqonga. Ngaphandle kwabo, abasebenzisi abanakwenza nantoni na ukusukela ukuba iinkqubo zokusebenza kwaso nasiphi na isixhobo esine-smart zigcinwa kwimemori yangaphakathi yezi diski.
Yintoni i-SSD hard drive?
Lo mbuzo unempendulo kwezobuchwephesha kwaye singachitha ixesha elide sichaza iindawo zeli candelo kodwa ngoku siza "kusika indlela" ukuze siphendule umbuzo ngendlela elula, eqondakalayo nekhawulezayo.
Idiski ye-SSD yindlalifa kwimemori ye-EEPROM kwaye isivumela ukuba sifunde kwaye sibhale ulwazi ngendlela enemveliso ngakumbi nangokufanelekileyo. Kwiinkumbulo ze-SSD ungafunda ulwazi oluninzi ngaxeshanye kwaye oku kuyinzuzo ecacileyo ngokubhekisele kwisantya sokufunda, into ethi Iyabonakala xa sithelekisa isantya sokuqalisa kwenkqubo yokusebenza efakwe kwi-hard drive ye-HDD okanye kwi-SSD drive. Iidiski ze-SSD ayizomatshini ngoko isantya sabo sokuqhubekeka ulwazi siphezulu kakhulu kunezo zoomatshini abanomda wokujikeleza ukujikeleza kunye nokufunda ulwazi.
Ngokubanzi, singatsho ukuba zonke izibonelelo zezi discs kodwa Kananjalo baneengxaki ezithile xa kuthelekiswa nokuqhuba kanzima, okunje ngobomi babo obuluncedo. Iidiski ze-SSD zinokuqina okuncinci ngenxa yokusetyenziswa kweetshipsi ezenziwe ngamasango e-NAND logic, kodwa ngaphandle kwamathandabuzo kukho izibonelelo ezingaphezulu kokungalunganga okusinika zona.
Isebenza njani i-SSD?
Ukusebenza kweediski ze-SSD yinxalenye ebaluleke kakhulu ekusetyenzisweni kwezixhobo zethu. Kwimeko yee-SSDs, zine-matrix eyaziwa njengebhloko, imiqolo eyaziwayo njengamaphepha. Umthamo wokugcina wee-SSD umiselwe yi inani lamaphepha kwibloko nganye.
Ukuze zisebenze zifuna isinxibelelanisi esibonakalayo kwaye ngokucacileyo ezi zinokwahluka ngohlobo lwebhodi edityaniswe kuyo. Ngokwesiqhelo indawo yoqhagamshelo ye-SSD yaziwa ngokuba yi-PCIe. Oku kusebenza ngokufanelekileyo ukudlulisa idatha ukusuka kwidiski ngokwayo kwibhodi kunye ne Iinkqubo okanye unxibelelwano I-AHCI edityaniswe nee-serial ATAs, kunye ne-NVMe ehambelana ne-PCIe.
Ukugcina ulwazi kwezi diski zongeza ii-transistors zamasango ezidadayo kwaye ezi zinokubakho ngaphakathi kwenkqubo yokubini: ilayishiwe okanye ayothulwanga. Ukuze singazenzi nzima izinto kakhulu, sinokuthi imeko elayishiwe imele inombolo 0, ngelixa ilizwe elikhutshelweyo liza kumela i-1.
Ubomi be-SSD, eyi-TRIM
Ubomi obuluncedo bee-SSDs xa kuthelekiswa neediski ezindala ze-HDD, njengoko besitshilo apha ngasentla, ubomi babo obuluncedo kwaye ngaphezulu kwako konke ukuba nzima kangakanani ukubonakalisa. Ii-SSDs zineentlobo ezahlukeneyo zokwenza imveliso ukuze ubomi babo buxhomekeke kuxhomekeke kubuchwepheshe obusetyenziselwa ukwenziwa kwazo. Asifuni ukungena kulo mbandela, kodwa singatsho ukuba inxalenye yobu bomi buluncedo iwela kwiseli esetyenzisiweyo. Sifumana iiseli ezizodwa, ezininzi, kathathu okanye ezine. Ezi zizigqibo kwaye ziya kuxhomekeka kwiichips ezingaphakathi kwidiski nganye.
Kwelinye icala sine-TRIM. Le yitekhnoloji eyenza ukuba kuncitshiswe inani lokususa kunye nokubhala ukusebenza kwee-SSDs ukuze zisebenze kwaye ubomi be-SSD buxhomekeke koku kungonakali kancinci. Izenzo ezimbalwa eziza kwenziwa yi-albhamu, ngcono, ke ngokuncinci uyenzayo, ixesha elide i-albhamu iya kuhlala. Iidiski zisusa okanye zisusa ulwazi kwimiqolo ngeebhloko kwaye ngaphakathi kwezi bhloko ezinye azinakususwa, ke ukuzihambisa kwenye indawo kubangela ukuba idatha ephawulweyo ibonakaliswe ngaphakathi kwidiski nakwimisebenzi elandelayo yokucima / yokubhala oku akufuneki idlule inkqubo kwakhona.
Yintoni ephunyeziweyo ngale TRIM kukuba idiski yethu inobomi obude okoko kunciphisa kakhulu ukusebenza kwaye le nkumbulo ingazinzanga ayonakalisi kangako, ewe, inkumbulo ephelelwa ziinyanga kwaye Oku kunxiba kukonyusa imisebenzi oyenzayo.
Umenzi ngamnye wongeza isiqwenga solwazi kumthengi kwiidiski zakhe kwaye ezi kunokubonwa ngokuzolileyo kubonisiwe njenge: I-TBW (iTerabytes ibhaliwe), iiP / E zeeCycle (Inkqubo-yokuSula uMjikelo), iMTBF (Ithetha ixesha eliphakathi kokusilela). I-TBW ibonisa ubungakanani bokubhala i-terabytes enokubhalwa, i-MTBF ibonisa inani eliqikelelweyo leeyure zobomi kwaye ii-P / E Cycles ziya kuba linani lokususa / ukubhala imijikelezo evunyelwe yi-SSD. Ngokwenyani, angamanani aqikelelweyo, kwaye akufuneki ukuba ube phambhi kuwo xa uthenga idiski.
Uncedo kunye nokungalunganga ngokuba ne-SSD hayi i-HDD
Ngale ndlela, sinokuchitha iiyure ezininzi sixoxa ngezona zinto ziluncedo okanye ezingalunganga omnye komnye, kodwa sifuna ukuyenza ibe ngokubanzi. Kule meko isantya see-SSDs xa kuthelekiswa nee-HDD zoomatshini lelona nqaku liphambili. Idiski ye-SSD ayinangxaki ininzi ukuba iwela emhlabeni, zincinci ngobukhulu kwaye ngaphezulu kwako konke zinokusetyenziswa kwamandla asezantsi kwiqela lethu eliya kuthi lixabise ngokuqinisekileyo.
Xa sinekhompyuter endala ene-HDD ukuba sibeka idiski ye-SSD siya kuqaphela Kabini ngokukhawuleza ukuqala inkqubo yokusebenza, izicelo, njl, Kwaye siya kukufumana ekukhanyeni kwezixhobo kuba zinobunzima obungaphantsi kakhulu.
Owona mqobo uphambili kwii-HDD kule meko kukuba zibiza kakhulu. Ngelixa kuyinyani namhlanje iidiski ze-SSD ziyafikeleleka kubo bonke abasebenzisi kwaye kukho lonke uhlahlo-lwabiwo mali, ixabiso liphezulu noko kuneediski ze-HDD kodwa kufanelekile. Enye into engalunganga okanye ukubuyela umva kwezi SSDs ngokungathandabuzekiyo kunokwenzeka ukuba uphulukane nawo wonke umxholo kwimeko yokusilela kwidiski. Ewe oku Kwi-HDD yakudala unokuzama ukufumana idatha kuyo ngesixhobo kodwa kwi-SSD inzima ngakumbi kwaye lonke ulwazi lunokulahleka njengememori yefleshi.
Umthamo wokugcina kwiidiski ze-SSD
Namhlanje ii-SSD zinomda othile wokugcina ubuncinci nangona ingezizo izakhono ezaneleyo kubasebenzisi abaninzi. Into eqhelekileyo kukubaleka kwi-SSD ye-256GB, i-512 GB, i-1 TB ukuya kuthi ga kwi-2 okanye kwiimeko ezinqabileyo ukuya kuthi ga kwi-4 TB. Lo mthamo wokugcina unokuchaphazeleka lixabiso eliphezulu lezinye zazo kwaye ziya kuxhomekeka kakhulu kumenzi kunye nomgangatho weli xabiso kwimarike.
Enye inkampani iyaziwa ukuba ineediski ze-SSD ezinkulu kunezi zibonisiwe ngaphambili, nangona kuyinyani ukuba ixabiso le- idiski ekumgangatho ophakathi ye-1TB inokufumaneka kwixabiso lama-euro angama-200. Kukho iimodeli ezingabizi kakhulu kwaye ezinye zibiza kakhulu ngomthamo ofanayo, yiyo loo nto kubaluleke kakhulu ukuba kucace malunga nokusetyenziswa esiza kunika i-SSD esiyifunayo kwaye ngaphezulu kwako konke ukubala malunga nokuba singakanani esona sithuba sisifunayo. Ilifu linokuninzi lokuthetha apha kuba kuya kusanda ukuba nesicwangciso sokugcina ilifu kwaye oku kunokuba nefuthe ekuqwalaselweni kwekhompyuter entsha kunye ne-SSD yayo yangaphakathi.
Amandla ee-SSD zangoku anele uninzi kodwa ngokuqinisekileyo ngokuhamba kwexesha oku kugcina kuya kufuneka kukhule kwaye amaxabiso ee-SSDs azokwehla njengokuba besenza ngoku. Ekuqaleni ezi SSD zazifumaneka kubasebenzisi abambalwa kodwa Kule mihla yeyona nto iqhelekileyo kwihlabathi ukuba olu hlobo lwediski lufakwe kwikhompyuter yakho.
