Ni ubuhe buryo Algorithms ikoreshwa kuri SSD vs HDD?
2024-09-19 14:17:26
Disiki ya Leta ikomeye (SSD) na Disiki zikomeye (HDD) zifite tekinoroji yihariye, kandi tekinike bakoresha mugucunga ububiko, kugarura amakuru, no gukora neza biratandukanye cyane.
Imbonerahamwe
1. SSD (Igikoresho gikomeye cya Leta) Algorithms
SSDs ikoresha flash yibuka ya NAND, kandi algorithms zagenewe kunoza umuvuduko, kwambara kuringaniza, no kuramba kubikoresho. Bimwe mubyingenzi algorithms ni:
Kwambara kuringaniza:
Intego: Iremeza ko kwandika / gusiba inzinguzingo bikwirakwizwa mu ngirabuzimafatizo zose zo kwibuka, bikarinda kwambara imburagihe kuri selile imwe.
Uburyo Bikora: Ubu buryo burigihe busuzuma ibice byo kwibuka bikoreshwa cyane kandi bigatanga amakuru kugirango wirinde gukoresha cyane blokisiyo.
Gukusanya imyanda
Intego: Kuraho amakuru atariyo (cyangwa amakuru yashizweho kugirango asibe) mumwanya wo kubohora umwanya no kunoza umuvuduko.
Uburyo Bikora: Iyo agace kamwe ko kwibuka karimo amakuru yemewe kandi atemewe, uburyo bwo gukusanya imyanda buhuza amakuru yemewe mugace kamwe hanyuma ikarekura izindi bice zo kubika amakuru mashya.
TRIM:
Intego: Itumanaho na SSD ihagarika amakuru atagikoreshwa kandi irashobora guhanagurwa, bityo kwihutisha ibikorwa byo kwandika.
Uburyo ikora: Iyo amakuru yangiritse, sisitemu y'imikorere yohereza amabwiriza ya TRIM kuri SSD, ikabimwemerera gusiba yagenwe guhagarika mbere yigihe, kugabanya kwandika ubukererwe.
Kode yo gukosora amakosa (ECC):
Intego: Kumenya no gukosora amakosa yamakuru ashobora kubaho mugihe cyo gusoma / kwandika.
Uburyo ikora: SSDs ikoresha amakosa yo gukosora algorithms kugirango tumenye neza ko amakuru ari ukuri, kuko NAND yibuka selile ishobora guhura namakosa ya biti.
Kurenza urugero:
Intego: Igenera ubushobozi bwo kubika kugirango ifashe kuringaniza imyenda, gukusanya imyanda, hamwe nibikorwa muri rusange.
Uburyo ikora: Ubu buhanga butanga flash yububiko bwinyongera butagaragara kubakoresha ariko bukoreshwa imbere na SSD mugucunga ibice byangiritse no kunoza imikorere.
Gucunga nabi:
Intego: Kumenya no gutandukanya ibice byo kwibuka bidakwiye.
Uburyo ikora: SSDs ikurikirana ubuzima bwibice byo kwibuka kandi ikanagaragaza ibyangiritse nkibidakoreshwa, ikemeza ko amakuru atigeze yandikwa kuri bisi mbi.
2. HDD (Disiki Ikomeye) Algorithms
HDDs ikoresha ibyuma bizunguruka kugirango ubike amakuru kandi usome / wandike imitwe kugirango uyigereho. Algorithms zabo zagenewe gucunga imiterere yumubiri wo kubika no kunoza imikorere. Algorithms z'ingenzi zirimo:
Gahunda ya Disiki ya Algorithms:
Intego:
Hindura uburyo urwego rwa disiki rugerwaho kugirango ugabanye igihe cyo gushakisha no gutinda.
Ingero:
Lifator (SCAN) Algorithm: Himura gusoma / kwandika umutwe mucyerekezo kimwe kugeza igeze kumpera ya disiki mbere yo gusubira inyuma, kugabanya impuzandengo yo gushakisha igihe.
Gushakisha Igihe gito (SSTF): Shyira imbere ibyifuzo byegereye umwanya wumutwe kugirango ugabanye igihe cyo gushaka.
Banza-Ngwino, Bwa mbere-Bikorewe (FCFS): Gutunganya ibyifuzo muburyo bikurikirana, nubwo ibi bidakorwa neza kuruta SSTF cyangwa SCAN.
Andika Cishing:
Intego: Kunoza imikorere yo kwandika ubika by'agateganyo amakuru muri cache mbere yo kuyandika kuri disiki.
Uburyo ikora: Data yandikiwe kububiko bwihuse bwa cache yibuka mbere, hanyuma yandikirwa buhoro buhoro disiki izunguruka mubice, bigabanya igihe rusange gikenewe mubikorwa byo kwandika.
Soma-Imbere Gufata (Gutegura):
Intego: Itezimbere imikorere yo gusoma uteganya ibyifuzo bizaza no gusoma amakuru muri cache mbere yuko bisabwa.
Uburyo ikora: Ukurikije uburyo bwo kugera, algorithm ibanziriza imizigo kuva mumirenge yegeranye cyangwa inzira muri cache kugirango igabanye gutinda gusoma.
Kumenya Amakosa no Gukosora (ECC):
Intego: Iremeza ubusugire bwamakuru yabitswe kuri disiki.
Uburyo ikora: HDD ikoresha algorithms ya ECC kugirango imenye kandi ikosore amakosa ashobora kubaho bitewe no guhuza magneti cyangwa kwambara hejuru yububiko.
Gusubiramo Imirenge mibi:
Intego: Yemeza ubunyangamugayo bwamakuru mu kohereza inyandiko kuva mumirenge mibi kugeza kumirenge.
Uburyo ikora: HDD ibika urutonde rwimirenge mibi kandi ikoresha imirenge isanzwe kugirango iyisimbuze, yemeza ko amakuru yanditswe ahantu hizewe ya disiki.
Gutesha agaciro:
Intego: Kuvugurura amakuru yatandukanijwe kugirango atezimbere gusoma no kwandika imikorere.
Uburyo ikora: Iyo dosiye zinyanyagiye mubice bitandukanye bya disiki (fragmentation), algorithm ya defragmentation algorithm itondekanya amakuru kugirango ihuze, igabanye igihe cyo gushakisha dosiye.
3. Incamake y'itandukaniro
SSD algorithms yibanda kumyambarire iringaniye, gukusanya imyanda, no gukosora amakosa kubera kwandika byanyuma bya flash yibuka.
Algorithms ya HDD yibanda mugutezimbere imikorere yubukanishi, nko kugabanya igihe cyo gushakisha no gukemura ibice bya disiki.
