I-SSD vs HDD: Yikuphi Okukulungele?

Uyini umehluko phakathi I-Ssd ne-Hdd? Ama-Solid State Drives (SSD) nama-Hard Disk Drives (ama-HDD) angase abelane ngokufana ngokomzimba, kodwa izindlela zawo zokugcina idatha zihluka kakhulu. Uhlobo ngalunye lokushayela lunobuhle kanye nokubi, futhi ukunquma ukuthi iyiphi ekufanelekelayo kuncike endleleni oyisebenzisa ngayo ikhompuyutha yakho. Umhlahlandlela wethu we-HDD vs. SSD wephula ukusebenza kohlobo ngalunye lwedrayivu yesitoreji nemithelela yako kuwe.

Asebenza kanjani ama-HDD:

Ama-HDD angamadivayisi esitoreji ayinkimbinkimbi ahlanganisa amapuleti azwelayo kazibuthe, ingalo ye-actuator enamakhanda okufunda/ukubhala, kanye nenjini yokuzungezisa ucwecwe. Ibuswa isilawuli se-I/O ne-firmware, lawa madrayivu ahlela idatha kumathrekhi agxilile nemikhakha. Ukubhala ama-algorithms kucubungula idatha ngaphambi kokugcina, okuvumela i-firmware ukuthi ibone futhi ilungise amaphutha. Isivinini socwecwe esisethiwe, esisuka ku-4200 siye ku-7200 rpm, sisho ukusebenza kahle kokubuyiswa kwedatha nezinqubo zokubhala kuma-HDD.

Inqubo yokufunda/yokubhala:

Ngaso sonke isikhathi lapho ucela ikhompuyutha ukuthi ithole noma ibuyekeze idatha, isilawuli se-I/O siyala ingalo ye-actuator lapho idatha itholakala khona, futhi amakhanda okufunda/ukubhala aqoqa idatha ngokufunda inkokhiso ekhelini ngalinye. Uma isicelo sibandakanya ukubuyekeza idatha, izinhloko ezifundwayo/zokubhala zishintsha inkokhiso kuthrekhi ethintekile kanye nomkhakha.

Amaphutha:

Izingxenye zemishini ezisetshenziselwa ukufunda nokubhala idatha kuma-HDD ziholela ezikhathini ezinde zokubuyisa uma kuqhathaniswa nezindlela ze-elekthronikhi. Izingxenye zikagesi zisengozini yokulimala uma zingaphathwanga kahle noma zehliswa, ikakhulukazi kumalaptop. Ama-HDD nawo asindayo futhi adla amandla amaningi uma kuqhathaniswa nama-Solid State Drives (SSDs).

Izinzuzo zama-HDD:

Ama-HDD awubuchwepheshe obuzamayo futhi obuyiqiniso, ngokuvamile bonga kakhulu kunama-SSD ngomthamo ofanayo wesitoreji. Njengamanje, ama-HDD anikezela ngezikhala ezinkulu zokugcina kune-SSD.

Iyini i-SSD (Solid State Drive)?

Indlela ama-SSD asebenza ngayo:

Ama-SSD asebenzisa inkumbulo ye-flash, ikakhulukazi ubuchwepheshe be-NAND, ngokusebenza okukhethekile nokuqina. Ngokungafani nama-HDD, ama-SSD awanazo izingxenye ezihambayo, athuthukisa ukuqina, asebenza emazingeni okushisa aphansi, futhi adla amandla amancane. Umsebenzi we-NAND ufaka izindleko zokuqopha ama-transistors antantayo ukuze kugcinwe idatha kusakhiwo sebhulokhi enephethini yegridi. Isilawuli se-SSD sidlala indima ebalulekile ekulandeleleni izindawo zedatha.

Inqubo yokufunda/yokubhala:

Kuma-SSD, ukuvuselela idatha kuyinkimbinkimbi kakhulu. Uma noma iyiphi ingxenye yebhulokhi ibuyekezwa, yonke ibhulokhi kufanele ivuselelwe. Idatha esuka kubhulokhi endala ikopishelwa kubhulokhi ehlukile, ibhulokhi iyasulwa, futhi idatha ibhalwa kabusha nezinguquko kubhulokhi entsha.

Noma nini lapho ucela ikhompuyutha ukuthi ibuyise noma ibuyekeze idatha, isilawuli se-SSD sibheka ikheli ledatha eceliwe futhi sifunde isimo sokushaja.

Ngezikhathi zokungenzi lutho, inqubo ebizwa ngokuthi ukuqoqwa kukadoti iqinisekisa ukuthi ulwazi kumabhulokhi amadala luyasulwa futhi lulungele ukubhalwa kabusha. Kukhona nenqubo ebizwa ngokuthi ukunquma, ukwazisa i-SSD ingakwazi ukweqa ukubhala kabusha idatha ethile ngesikhathi sokusulwa kwebhulokhi. Lokhu kubalulekile ukuze kuvinjelwe ukuguga ngaphambi kwesikhathi kudrayivu, njengoba ibhulokhi ngalinye linenani elilinganiselwe lemijikelezo yokufunda/yokubhala.

Ukuze kuthuthukiswe ukuguga, i-algorithm iqinisekisa ukuthi ibhulokhi ngayinye kudrayivu ithola inani elilinganayo lezinqubo zokufunda/zokubhala. Le nqubo, eyaziwa ngokuthi i-wear leveling, iyenzeka ngokuzenzakalelayo njengoba idrayivu isebenza.

Njengoba izinqubo zokufunda/ukubhala zifaka phakathi ukunyakaza kwedatha, ama-SSD avame ukuba nesikhala sokugcina sokuhlinzekwa okungaphezu kokuhlinzekwa. Inani elithile ledrayivu alibikwa kusistimu yokusebenza futhi alifinyeleleki kubasebenzisi. Lokhu kunikeza isikhala sokuthi idrayivu inyakaze futhi isuse izinto ngaphandle kokuphazamisa umthamo wesitoreji.

Amaphutha:

Ama-SSD awubuchwepheshe obusha, yingakho ebiza kakhulu kunama-HDD. Nakuba ukubamba, ukuthola okusezingeni eliphezulu-Amandla Ssds kungase kube inselele kakhulu uma kuqhathaniswa nama-HDD. Ama-HDD anganikela ngokufika kokuphindwe ka-2.5 komthamo wama-SSD.

Izinzuzo zama-SSD:

Kungani ukhethe i-Solid State Drive? Ama-SSD angasheshisa isivinini sokulayisha semidlalo, izinhlelo zokusebenza, namamuvi. Ngenxa yobuchwepheshe obusetshenzisiwe, ama-SSD alula, amelana kangcono nokunyakaza nokwehla, futhi adla amandla amancane, okuholela emazingeni okushisa aphansi okusebenza.

Enye yezinzuzo ezibalulekile zama-SSD:

Ingabe ijubane labo elishesha kakhulu uma liqhathaniswa nama-HDD. Isibonelo, uchungechunge lwe-G-BONG X, i-NVMe SSD yethu eshesha kakhulu, inikeza isivinini esimangalisayo sokufunda/ukubhala esingafika ku-3400/3000MB/s. Ngisho nama-SSD aphathekayo adlula ama-HDD. Ngesivinini sokufunda esingafika ku-1050MB/s namandla afika ku-2TB, i-X8 ishesha izikhathi eziyi-100 kune-USB flash drive futhi ishesha izikhathi ezingu-7.5 kunama-hard drive endabuko.

Isinqumo

Umehluko phakathi kwama-hard drive namadrayivu wesimo esiqinile usebuchwephesheni obusetshenziswa ukugcina nokubuyisa idatha. Ithebula elingezansi libonisa eminye yemehluko.

Ama-HDD ashibhile futhi ungathola indawo yokugcina eyengeziwe. Ama-SSD, nokho, ayashesha ngendlela emangalisayo, alula, ahlala isikhathi eside, futhi asebenzisa amandla amancane. Izidingo zakho zizosho ukuthi iyiphi idrayivu yokugcina ezokusebenzela kangcono.
