Kukuphi na okulunge ngakumbi: SSD okanye HDD? Yintoni umahluko phakathi SSD ne HDD?

Xa uthenga PC omtsha okanye kuphuculwe inkqubo disk ubudala ikhompyutha ngokuyimfuneko kuphakamisa umbuzo: "Nguwuphi na kangcono - SSD okanye HDD» kwiminyaka emihlanu edlulileyo, lo mbuzo asivelanga. Alternatives to kulimo hard disk wayengekho (igama lakhe yesibini - "hard drive" okanye "iqhosha lemenyu"). Ngoko ke, oko isixhobo enjalo yokugcina ulwazi kusetyenziswa yonke indawo. Kodwa ngoku meko itshintshe kakhulu. Iya isanda, abasebenzisi ingqalelo drives eqinileyo-karhulumente, leyo, nangona zininzi zibiza imali eninzi, kodwa intsebenzo yabo iphezulu kakhulu.

indaba

Phambi kokuba ufumanise ukuba yintoni umahluko phakathi SSD kunye HDD, sithatha ngokutsha ngokufutshane nembali kwaye ukhangele nobuchwepheshe yokugcina data esetyenziswa kuzo zonke hlobo device.

Uqhubo lokuqala ngokupheleleyo kwi-hard disk (igama elisemthethweni) yenziwa ngu IBM Corporation kunyaka 1973. Ke umthamo walo 60 MB (2 MB ukusuka iipleyiti 30). Kule minyaka ingama-40-odd elidlulileyo, izixhobo ezifana ekhulisa, kunye neempawu zazo ziye zaphucuka nge amatyeli ngamatyeli - izakhono kunye nokusebenza. Kodwa technologies hayi zitshintshiwe. Isiseko salo naliphina HDD (kwigama IsiNgesi «nzima» - nzima, «disk» - drive kwaye «drive» - kule meko drive) teka ipleyiti isale umaleko ferromagnetic. Intloko kube kudala orientation ethile ( "emantla" yaye "emzantsi" nezibonda ezihambelana ubhalo "0" yaye "1"). SSDs zaye kuqala kuqaliswa ngo-1978. Kodwa abantu abaninzi basala ukusebenzisa kwabo esanda - i-PC yokuqala kunye nabo njengoko isixhobo engundoqo yokugcina, wabonakala ngo-2009. izixhobo zokugcina Solid-karhulumente zisekelwe ngezinto semiconductor, leyo iqanjwa "iiseli". Xa i "iseli" enjalo kubhalwa amaxabiso amabini kuphela "0" (akukho uphawu) kunye "1" (langoku enokubakho). Ngoko ke umahluko phakathi HDD ne SSD. Umahluko ukusuka HDD kuba oko kusetyenziswa ukuvelisa enye into (lesilicon anti-ferromagnet) waza wenza umgaqo yokugcina ulwazi (ICS ngokuchasene plate). Ngayo ukukhumbula xa ukhetha isixhobo esitsha eklasini yayo.

Le version zakudala

Ukuze siphendule lo mbuzo, yintoni na ngcono - SSD kunye HDD, khangela isixhobo ngasinye yokugcina ngabanye ulwazi. Ukuqala lesibini kubo. Olu uhlobo ezaziwa lombutho le nkqubo kwidisk. Eyona engundoqo iimpawu-hard drive ngolu hlobo lulandelayo:

• Capacity - isixa iinkcukacha zigcinwa wokugqibela kwinkqubo inani. Ngelo xesha oku salathisi kwi indlela yokusebenza iza kuba ezahlukileyo, kuba apha ukubala sele kwinkqubo yokubini. Okwangoku umthamo yokugcina ekhoyo ngokorhwebo ka 250 GB ukuya 8 TB.
• uqhagamshelo interface kungaba IDE, USB kunye wada wabiliswa uphela. Eyokuqala kubo ngokuziphatha nasemzimbeni lixesha kwaye isetyenziswa kuphela kwi-PC ukuba baye bakhululwa kweminyaka emi-5 edlulileyo kwaye ngaphambili. Eyesibini mkhulu ephathekayo ukugcinwa data. Okwesithathu, ukuba eziphambili - ngoku zingasetyenziswa jikelele. inguqulo yakhe ekugcineni i index ye '3 ". Zonke izixhobo ezinokuthi ukusebenza oluguqulelo lwe zojongano ukuba angadlulisela data kwi ukuya ku-6 Gb / s. Kwakhona, wada wabiliswa uphela luguqulelo olukhethekileyo kunye index «m», nesetyenziswa kuphela laptops kunye netbooks.
• Izinga transfer data. Njengoko sibonile ngaphambili, kuxhomekeke kudidi lwe interface. I aphezulu ke, ngcono.
• nesonkana esisicaba ukujikeleza frequency. Ke kaloku athotyiweyo kukho imifuziselo 5400 no 7200. ngomzuzu. Yintoni le nani liphezulu, kungona yokusebenza.

Ngabo aba eziphambili iimpawu hard disk. Ukuze siphendule lo mbuzo, yintoni na ngcono - SSD kunye HDD, kufuneka ucinge parameters okuqinileyo-state drives. Oko kuya kwenziwa.

Ukwazi

Ngenye indlela, njengokuba ukwazi, lo SSD akayi igama. Ezi zixhobo waya athotyiweyo kwiminyaka emihlanu edlulileyo. Ngoko nangoko nemiqobo zintoni na iindleko zabo eziphakamileyo kunye nobukhulu enkulu. Kodwa ngoku le meko ngokuthe iyatshintsha. Iya isanda, ukuba lungafumaneka kwi desktops kunye laptops. iimpawu eziphambili ube nalemiba ilandelayo:

• Capacity - iyafana naleyo-hard drive. Ngoku imifuziselo iyafumaneka kwi-32 GB 1 TB.
• inkqubo yokuvelisa ingaba ukusuka 19 NM ukuya 26 NM. I-mbalwa, ukusebenza ngcono, kodwa lunciphisa inani leeseli ubhale mijikelo.
• Uxhulumaniso esibonakalayo. Bonke bephela ayafana nalawo enikwe ngaphambili ngenxa HDD, ngaphandle IDE, nto leyo esetyenziselwa SSD.
• Inani ubhale mijikelo. Kusenokuba ukususela 1000 ukuya 5000 mijikelo. Ukuba liphakamile ixabiso, ixesha elide SSD.

Ngenxa yoku kungasentla, unako lula ukunika impendulo oko yahlukile kwi SSD HDD nokuba ingcono.

Thelekisa drives

Ukuthelekisa ukusebenza nganye drives oko kuqatshelwe ukuba urhulumente eziqinileyo engaphezulu data. Oku kuqinisekiswa yi ubuchwepheshe ngokwayo. IMicrochips kwesi sicwangciso ulunge ngaphezu amacwecwe ngemagnethi. Ngomhla ezilungileyo olu hlobo kwezixhobo ekupheleni. Ukuba uthelekise iindleko kunye nobukhulu drive, kuvela ukuba ngexabiso ka 40-50 USD unako ukuthenga GB 32 SSD okanye HDD 160-250 GB. Ngenxa yoko, ukhetho abasebenzisi abaninzi. Ngexabiso elifanayo bekuya kuba ngcono izinga lelizwi ngaphezu komsebenzi. Kwakhona, isikhundla esiphezulu kwi HDD amaxesha 8 ngaphezulu (1 GB 8 GB).

Yintoni yaye uphi na ngakumbi?

Ngoku makhe ukujamelana oko kulungileyo - lo SSD okanye HDD - kwimeko nganye. Yezikhululo multimedia kunye iiPC ofisi ugqibelele ukuba drives hard kunye nomthamo 160-320 GB. Kwaye ke ixabiso iphantsi, yaye oku ubukhulu iya kuba yanele ingxaki ekufuneka isonjululwe. Kanye imeko netbooks kunye laptops entry-level. Kodwa iikhompyutha high-intsebenzo iya kuba ubungakanani SSD bakulungele ka 128-256 GB. Zomdlalo PC, workstations imizobo kunye iiseva kufuneka ekufuneka ifakwe 2 drives. Enye Iinkqubo kunye neenkqubo - le SSD. Nowesibini - i hard drive apho ukugcina idatha yomsebenzisi. Oku kuya kufumana kunye ngesantya esiphezulu, kwaye umthamo efunekayo ukwenzela ukugcinwa data.

iziphumo

Njengenxalenye yale nqaku ukwenza uthelekiso olunzulu HDD kunye SSD, ebonisa iimpawu eziphambili, iingcebiso ukusetyenziswa kwazo, ulandelayo ungakwazi ngokulula achole isixhobo yokugcina ulwazi oluya zilungele iimfuno zakho.
