Yikuphi okungcono: SSD noma HDD? Uyini umehluko phakathi SSD futhi HDD?

Lapho uthenga i-PC entsha noma ukuthuthukisa isistimu disk endala ikhompyutha ngempela uphakamisa lo mbuzo: "Yikuphi okungcono - SSD noma HDD» Eminyakeni emihlanu eyedlule, lo mbuzo asivelanga?. Zokwelapha Ezingahileli ezivamile idrayivu kanzima wayengekho (igama lakhe lesibili - "hard drive" noma nje "isikulufa"). Ngakho-ke, leli thuluzi ngoba nokugcina ulwazi esetshenziswa yonke indawo. Kodwa manje isimo sesishintshile kakhulu. Bayanda abasebenzisi sinake ngemoto esiqinile isimo, okuyinto, nakuba zinezikhwepha ezibizayo, kodwa ukusebenza kwazo iphezulu kakhulu.

indaba

Ngaphambi uthole ukuthi yini umehluko phakathi SSD kanye HDD, sithatha a Kubuketa umlandvo lomfishane eliphelele bese ibheka ubuchwepheshe isitoreji idatha isetshenziswa esazo zonke kudivayisi.

Ukuhamba umnyuziki lokuqala disk hard (igama elisemthethweni) esenziwa IBM Corporation onyakeni 1973. Khona-ke umthamo salo 60 MB (2 MB kusuka 30 amapuleti). Eminyakeni engu-40-lingalingani iminyaka, amadivayisi njenge ziye zashintsha, futhi izici zabo ziye zaguqulwa izikhathi eziningana - kokubili umthamo kanye nokusebenza. Kodwa ubuchwepheshe azishintshiwe. Isisekelo sanoma ibuphi HDD (kusukela igama lesiNgisi «kanzima» - kanzima, «disk» - drive kanye «drive» - kulesi simo idrayivu) itholakala ipuleti camera nge ungqimba ferromagnetic. Nge ikhanda kwakha umumo othile ( "ngasenyakatho" futhi "eningizimu" izingongolo ezihambisana okunengqondo "0" futhi "1"). SSDs bathola ngo-1978. Kodwa okwandile ukusebenzisa kwabo samuva nje - le PC lokuqala nabo njengoba kule yesitoreji esikhulu, uvele 2009. amadivaysi isitoreji Solid-isimo zisekelwe Semiconductor izinto, okuyinto akhiwa "amaseli". Encwadini "ingqamuzana" enjalo kungenziwa ebhaliwe amagugu "0" (akunasiginali) kanye "1" (abakhona engaba) ezimbili kuphela. Yingakho umehluko phakathi HDD kanye SSD. Umehluko kusuka HDD ke yilokhu isetshenziswa ekukhiqizeni nezinye izinto (Silicon anti-ferromagnet) futhi wenza isimiso kolwazi isitoreji (ICS ngokumelene ipuleti). Mayelana-ke ukukhumbula lapho ukhetha idivayisi entsha ekilasini yayo.

I version zakudala

Ukuze uphendule lo mbuzo, lokho kungcono - SSD kanye HDD, ukubheka idivayisi ngamunye isitoreji ngamunye ulwazi. Ukuze uqale yesibili wabo. Lona okufana zakudala lenhlangano kohlelo disk. I izici eziyinhloko the drive kanzima ngale ndlela:

• Umthamo - inani ulwazi egciniwe ku idesimali inombolo system. Ngesikhathi esifanayo lo inkomba ohlelweni lokusebenza kuzohluka, ngoba lapha ukubala usuvele uhlelo kanambambili. Okwamanje isitoreji umthamo itholakale emakhemisi of 250 GB kuya 8 TB.
• uxhumano esibonakalayo kungaba IDE, USB ne Sata. Eyokuqala wabo ukhuluma ngokuziphatha nangokwenyama akusebenzi futhi usetshenziswa kuphela PC ukuthi sebededeliwe 5 iminyaka edlule futhi ngaphambili. Eyesibili kakhulu ephathekayo isitoreji idatha. Okwesithathu, i-main - manje zisetshenziswa cishe yonke indawo. Inguqulo yakhe yokugcina Lunezikhombo "3". Wonke amadivayisi ingasebenza ngale nguqulo kokusetshenziswa kubonwa ezingaba ukudlulisa idatha at kuze 6 GB / s. Futhi, Sata inguqulo okhethekile onenkomba «m», okuyinto esetshenziswa kuphela ama-laptop netbooks.
• Izinga ukudluliswa kwedatha. Kodwa njengoba sekushiwo ngaphambili, incike uhlobo esibonakalayo. Ayanda kunjalo, ngcono.
• esilucwecwana Ukujikeleza imvamisa. Manje ezisendalini kukhona onobuhle 5400 futhi 7200. ngeminithi. Yini lesi sibalo ephakeme, ayanda ukusebenza.

Lawa main izici idrayivu kanzima. Ukuze siphendule lo mbuzo, lokho kungcono - SSD kanye HDD, kudingeka ucabangele kwemigomo ngemoto esiqinile isimo. Yini-ke kuzokwenziwa ku.

Yazi-nendlela

Ngenye indlela, njengoba kokuxazulula, SSD ngeke uqambe. Lezi amadivayisi waqhubeka ukudayiswa eminyakeni emihlanu edlule. Ngokushesha izingqinamba ezinamanani aphansi zazo eziphakeme kanye nosayizi omkhulu. Kodwa manje isimo kancane kancane kokushintsha. Bayanda betholakala khona ku amadeskithophu kanye laptops. Izici Main babe naloku lokulandzelako:

• Umthamo - kuyafana ukuthi we hard drive. Manje onobuhle kuyatholakala kusuka 32 GB kuya ku-1-TB.
• inqubo Ukukhiqiza kungaba kusuka 19 NM 26 NM. I ezimbalwa, ukusebenza ngcono, kodwa kunciphisa inani lamaseli isula imijikelezo.
• Uxhumano esibonakalayo. Bonke bangabangasokile ezifana nalezo ngaphambilini sinikezwa ngesizathu HDD, ngaphandle IDE, okungasekelwe esetshenziselwa SSD.
• Isibalo bhala imijikelezo. Kungenzeka kusuka 1000 kuya 5000 nowe. Ayanda Inani, isikhathi eside SSD.

Ngokusekelwe kulokhu okungenhla, ungakwazi kalula nimphendule nalokho lihlukile SSD HDD nokuthi umuntu ongcono.

Qhathanisa ngemoto

Ukuqhathanisa ukusebenza ngamunye ngemoto kungase kuqashelwe ukuthi isimo okuqinile abe izinga idatha ephakeme. Lokhu kuqinisekiswa ubuchwepheshe uqobo. Microchip leli cebo ungcono amapuleti kazibuthe. On izinzuzo lolu hlobo kumadivayisi ekupheleni. Uma uqhathanisa izindleko kanye nosayizi idrayivu, kuvela ukuthi ngentengo 40-50 USD kungaba uthenga 32 GB SSD noma HDD 160-250 GB. Ngakho, i-choice kubasebenzisi abaningi. Ngesikhathi amanani efanayo ukuthi kungaba ivolumu kangcono okukhulu ngaphandle kokusebenza. Futhi, ngomthamo usuwonke ku HDD izikhathi 8 ngaphezulu (1 GB kuya ku-8 GB).

Yini futhi lapho kungcono?

Manje ake ukubhekana ukuthi ikuphi okungcono - SSD noma HDD - esimweni ngasinye. Ukuze iziteshi multimedia nehhovisi PC zimi kahle zilungele hard drive nge namandla 160-320 GB. Futhi intengo iphansi, futhi lokhu usayizi kuyoba okwanele ngezinkinga ukuba ixazululwe. Kunesimo esifanayo ne netbooks futhi entry level-laptops. Kodwa ukusebenza okuphezulu amakhompyutha yeselula ngeke ahlonyiswe kangcono usayizi SSD ka 128-256 GB. Gaming PC, ihluzo workstations futhi amaseva kumuntu kumele kudingeke ukuthi ifakelwe ngemoto 2. Omunye izinhlelo kanye nezinhlelo - lokhu SSD. Owesibili - idrayivu kanzima lapho ukugcina idatha yomsebenzisi. Lokhu uzothola futhi ngesivinini, futhi umthamo adingekayo isitoreji idatha.

Imiphumela

Njengengxenye lesi sihloko sasisihle ukwenza ukuqhathanisa olunzulu HDD kanye SSD, okubonisa izici zabo main, izincomo ukusetshenziswa kwabo, kulandela lapho ungakwazi kalula pick up idivayisi Imininingwane isilondolozi uzobalungela zakho ezihamba phambili.
