Ama-hard drive e-SSD yimishini yehadiwe esivame ukuyibona ngokomzimba kepha esetshenziselwa ukugcina okuqukethwe kwazo zonke izinhlobo. Ngaphandle kwalokhu I-SSD ehambelana negama layo Idiski Eqinile Yesizwe amadivayisi wethu azodinga ezinye izinto ukugcina izithombe, umculo, amafayela, amadokhumenti nokuningi.
Namuhla sifuna ukuhlanganyela nawe 5 okhiye bale SSD hard drive ukuze uyiqonde futhi ngaphezu kwakho konke okwaziyo ukubaluleka abanakho ngaphakathi kwanoma yiliphi iqembu namuhla. Ngaphandle kwama-SSD kungaba nzima ukugcina yonke imininingwane esinayo namuhla.
Ngaphandle kokungabaza singasho ukuthi i-SSD ye-PC yethu noma iMac ingenye yezingxenye ezibaluleke kakhulu zehadiwe, futhi ingeye-smartphone noma i-console yomdlalo. Ngaphandle kwabo, abasebenzisi bebengeke benze lutho ngoba izinhlelo zokusebenza zanoma iyiphi idivayisi ehlakaniphile zigcinwa kwimemori yangaphakathi yalawa madiski.
Yini i-SSD hard drive?
Lo mbuzo unempendulo yezobuchwepheshe futhi singachitha isikhathi eside sichaza izingxenye zalesi sakhi kodwa njengamanje "sizosika umgwaqo" ukuphendula umbuzo ngendlela elula, eqondakalayo futhi esheshayo.
Idiski ye-SSD ilandela imemori ye-EEPROM futhi isivumela ukuthi sifunde futhi sibhale imininingwane ngendlela ekhiqiza kakhulu nephumelelayo. Kumemori ye-SSD ungafunda imininingwane eminingi ngasikhathi sinye futhi lokhu kuyinzuzo ecacile maqondana nejubane lokufunda, okuthile okuthi kuyabonakala lapho siqhathanisa isivinini sebhuthi sohlelo lokusebenza olufakwe kwi-hard drive HDD noma idrayivu ye-SSD. Ama-disks e-SSD awawona amashini ngakho isivinini sabo sokucubungula ulwazi siphakeme kakhulu kunaleso esenziwe ngemishini esinezinguquko ezithile ezinqunyelwe ukujikeleza nokufunda imininingwane.
Ngokubanzi, singasho ukuthi konke kuyinzuzo ngalawa madiski kodwa Futhi banezinye izingqinamba uma kuqhathaniswa nama-hard drive, njengempilo yabo esebenzisekayo. Amadiski e-SSD anokuqina okuncane ngenxa yokusebenzisa ama-chips akhiwe ngamasango we-NAND logic, kepha ngaphandle kokungabaza kunezinzuzo eziningi kunokubi abasinikeza zona.
Isebenza kanjani i-SSD?
Ukusebenza kwamadiski e-SSD kuyingxenye ebaluleke kakhulu ekusetshenzisweni kwemishini yethu. Endabeni yama-SSDs, ane-matrix eyaziwa njenge-block, imigqa eyaziwa njengamakhasi. Amandla okugcina ama-SSD anqunywa yi- inani lamakhasi ngaphakathi kwebhulokhi ngalinye.
Ukuze zisebenze zidinga isixhumi somzimba futhi kusobala ukuthi lezi zingahluka ngokuya ngohlobo lwebhodi ezixhumeke kuzo. Imvamisa imbobo yokuxhuma ye-SSD yaziwa nge-PCIe. Lokhu ngokunengqondo kusebenza ukudlulisa idatha kusuka kudiski uqobo kuyise ebhodini nasefayilini ye Izivumelwano noma isikhombimsebenzisi sokuxhumana I-AHCI exhunywe kuma-Serial ATAs, kanye ne-NVMe ehlotshaniswa ne-PCIe.
Ukonga imininingwane lawa madiski angeza ama-transistors esango entantayo futhi angaba ezifundazweni ezimbili ngaphakathi kohlelo lwe-kanambambili: alayishiwe noma alayishiwe. Ukuze singazenzi izinto zibe nzima kakhulu singasho ukuthi isimo esilayishiwe simele inombolo 0, ngenkathi izwe elilandiwe lizomela i-1.
Isikhathi sempilo se-SSD, okuyi-TRIM
Impilo esebenzisekayo yama-SSD uma iqhathaniswa namadiski amadala e-HDD, njengoba, njengoba sishilo ngenhla, impilo yawo ewusizo futhi ngaphezu kwakho konke ukuthi kunzima kangakanani ukuyilimaza. Ama-SSD anezinhlobo ezahlukahlukene zokukhiqiza ngakho-ke impilo yawo izoncika kubuchwepheshe obusetshenziselwa ukwenziwa kwabo. Asifuni nokungena kulolu daba, kepha singasho ukuthi ingxenye yalokhu kuphila okusebenzisekayo iwela esitokisini esisetshenzisiwe. Siyathola amaseli angashadile, amaningi, amathathu noma amane. Lezi zinqumo futhi zizoxhomeka kuma-chips angaphakathi kwediski ngalinye.
Ngakolunye uhlangothi sine-TRIM. Lobu ubuchwepheshe obenza ukuthi kube nokwenzeka ukunciphisa inani lokusula nokubhala ukusebenza kwama-SSD ukuze kusebenze futhi nempilo yama-SSD nayo incike kulokhu kungagugi kangako. Izenzo ezimbalwa i-albhamu okufanele izenze, ziba ngcono, ngakho-ke uma wenza okuncane, i-albhamu izohlala isikhathi eside. Ama-disks asula noma ahambisa imininingwane kusuka emigqeni ngamabhulokhi futhi ngaphakathi kwalawa mabhulokhi amanye awakwazi ukuqedwa, ngakho-ke ukuwahambisa kwenye indawo kubangela ukuthi idatha emakiwe ibonakale ngaphakathi kwediski nakumisebenzi elandelayo yokusula / yokubhala lokhu akudingeki kudlule inqubo futhi.
Okuzuzwayo ngale TRIM ukuthi idiski yethu inempilo ende ngoba yehlisa ukusebenza kakhulu futhi le nkumbulo eguquguqukayo yehlisiwe kancane, yebo, inkumbulo ephela ezinyangeni nokuthi Lokhu kugqoka kwandisa ukusebenza okwengeziwe okwenzayo.
Umkhiqizi ngamunye ungeza ulwazi olubalulekile lomthengi kuma-disc akhe futhi lokhu kungabonakala ngokuthula kuboniswa njengo: I-TBW (Kubhalwe iTerabyte), Imijikelezo ye-P / E (Umjikelezo Wokusula Uhlelo), i-MTBF (Isikhathi Esiphakathi Kokwehluleka). I-TBW ikhombisa inani lama-terabyte wokubhala angabhalwa, i-MTBF ikhombisa inani elilinganiselwe lamahora okuphila kanti Imijikelezo ye-P / E kungaba inombolo yemijikelezo yokusula / yokubhala evunyelwe yi-SSD. Empeleni, zingamanani alinganiselwe, futhi akufanele ukhathazeke ngawo lapho uthenga i-disc.
Ubuhle nobubi bokuba ne-SSD hhayi i-HDD
Ngalo mqondo, singachitha amahora amaningi sidingida izinzuzo nezinkinga ezinkulu zomunye nomunye, kepha sifuna ukukwenza kube okujwayelekile. Esimweni esinjalo ijubane lama-SSDs uma kuqhathaniswa nama-HDD ayimishini iphuzu elisemqoka. Idiski ye-SSD ayinayo inkinga enkulu uma iwela phansi, mincane kakhulu ngosayizi futhi ngaphezu kwakho konke inokusetshenziswa kwamandla okuphansi iqembu lethu elizokuthokozela impela.
Lapho sinekhompyutha endala ene-HDD uma sibeka i-SSD disk sizobona Kabili ngokushesha ukuqala uhlelo lokusebenza, izicelo, njll, futhi sizothola ekukhanyeni kwemishini ngoba inesisindo esincane kakhulu.
Okubi kakhulu ngama-HDD kuleli cala ukuthi kubiza kakhulu. Yize kuyiqiniso namuhla ukuthi amadiski e-SSD ayatholakala kubo bonke abasebenzisi futhi akhona kuwo wonke amabhajethi, inani liphakeme ngaphezudlwana kunamadiski e-HDD kepha kufanelekile. Okunye ukungalungi noma ukubuyela emuva kwalawa ma-SSD ngokungangabazeki kungenzeka ukulahlekelwa yikho konke okuqukethwe uma kwenzeka ukwehluleka kwediski. Yebo lokhu Ku-HDD endala ungazama ukuthola eminye imininingwane kuyo ngethuluzi kepha kwi-SSD kunzima kakhulu futhi yonke imininingwane ingalahleka njengoba iyi-flash memory.
Umthamo wesitoreji kumadiski e-SSD
Namuhla ama-SSD anesilinganiso esithile esilinganiselwe sokugcina yize kungewona amandla anele kubasebenzisi abaningi. Into ejwayelekile ukugijimela kwi-SSD ye-256GB, i-512 GB, i-1 TB ize ifike ku-2 noma ezimweni ezixakile kuze kufike ku-4 TB. Lo mthamo wesitoreji ungathinteka ngamanani aphezulu ezinye zazo futhi kuzoya kakhulu kumenzi nakukhwalithi yale ntengo emakethe.
Enye inkampani iyaziwa ukuthi inamadiski e-SSD amakhulu kunalawa akhonjiswe phambilini, yize kuliqiniso ukuthi intengo ye- i-disk esezingeni eliphakathi ne-1TB ingatholakala ebangeni lentengo lama-euro angama-200. Kunamamodeli ashibhile futhi amanye abiza kakhulu ngomthamo ofanayo, yingakho kubaluleke kakhulu ukuthi kucace ngokusetshenziswa esizokunika i-SSD esiyifunayo futhi ngaphezu kwakho konke ukubala ukuthi singakanani isikhala sangempela esisidingayo. Ifu linokuningi okushiwo lapha ngoba kuya ngokuya kujwayeleka ukuba nohlelo lokugcina amafu futhi lokhu kungathinta ukucushwa kwekhompyutha entsha ne-SSD yangaphakathi.
Amandla ama-SSD amanje anele iningi kodwa ngokuhamba kwesikhathi lesi sitoreji kuzodingeka sikhule futhi amanani ama-SSD azokwehla njengoba enza njengamanje. Ekuqaleni la ma-SSD ayetholakala kubasebenzisi abambalwa kepha kulezi zinsuku kuyinto ejwayelekile kunazo zonke emhlabeni ukuthi lolu hlobo lwediski lufakwe kwikhompyutha yakho.
