Ubuchwepheshe besitoreji se-RAID kuma-laptop
Ukuthuthukiswa kwama-laptops esimanje akugcini nje ngokukhawulelwa emiklamo emincane nelula, kodwa futhi nasemakhonweni okugcina asheshayo, amakhulu, futhi aphephile. Yilapho i-RAID (i-Redundant Array of Independent Disks) iba yisihloko esithakazelisayo. I-RAID ubuchwepheshe obuhlanganisa imidiya yokugcina emibili noma ngaphezulu (i-SSD noma i-HDD) ukuze isebenze njengeyunithi ngenhloso ethile: ukuthuthukisa ukusebenza, ukwandisa ukuthembeka kwedatha, noma kokubili. Ngenkathi i-RAID ithandwa kakhulu kumaseva nasezindaweni zokusebenza, ukusetshenziswa kwayo kuma-laptops—ikakhulukazi lawo asemaklasini emidlalo, abadali, kanye nochwepheshe—kuya ngokuya kufaneleka ngenxa yesidingo esikhulayo sesivinini kanye nokuphepha kwedatha.
Iyini i-RAID futhi isebenza kanjani?
Kalula nje, i-RAID isebenzisa amadrayivu amaningi ukuhlela idatha ngendlela ethile. Ezinye izilungiselelo ze-RAID zisebenzisa i-striping ukubhala idatha ngokushesha, kanti ezinye zisebenzisa i-mirroring ukuphinda idatha uma kwenzeka idrayivu eyodwa yehluleka. Amanye amazinga e-RAID aze ahlanganise lokhu kokubili.
Kuma-laptop, i-RAID ivame ukusetshenziswa kusetshenziswa ama-SSD amabili e-NVMe (ngokuvamile ngefomethi ye-M.2) noma inhlanganisela ye-SSD ne-HDD, yize inhlanganisela yesimanje evame kakhulu ama-SSD amabili e-NVMe ngenxa yobukhulu bawo obuncane kanye nokusebenza okuphezulu. Kodwa-ke, kubalulekile ukuqaphela: akuwona wonke ama-laptop asekela i-RAID. Ukusekelwa kuncike enanini lezikhala zokugcina, ukwesekwa kwe-BIOS/UEFI, kanye nesilawuli esisetshenziswayo—kungakhathaliseki ukuthi yi-chipset noma isisombululo esisekelwe kusofthiwe.
Isizathu sokuthi i-RAID iqala ukubonwa kuma-laptop
Kunezizathu ezintathu eziyinhloko zokuthi kungani abasebenzisi becabanga nge-RAID kwi-laptop:
1. Ukusebenza okuphezulu
Imisebenzi efana nokuhlela ividiyo ye-4K/8K, ukuhlanganisa ikhodi enkulu, ukuphatha amasethi edatha, noma ukulayisha imidlalo esindayo ingazuza ngokufakwa okuphezulu kwesitoreji.
2. Ukuthembeka kwedatha nokuphepha kwayo
Ama-laptop avame ukuthuthwa, okwandisa ingozi yokuwa, ukushaqeka, noma ukusetshenziswa okungafanele. I-RAID enokuphindaphinda inganciphisa ingozi yokulahleka kwedatha ngenxa yokwehluleka kwedrayivu.
3. Ukuphathwa kwamandla
Ukuhlanganisa amadrayivu amabili ukuze avele njengomthamo owodwa omkhulu kungenza ukuphathwa kwe-partition kube lula—yize lokhu kungeyona inhloso eyinhloko yama-RAID amaningi anconywayo.
Amazinga e-RAID ajwayelekile nafanele kuma-laptops
Akuwona wonke amazinga e-RAID afanelekela ama-laptop. Nazi amazinga avame kakhulu:
1) I-RAID 0 (Ukweqa) – ukugxila kwesivinini
I-RAID 0 ihlukanisa idatha phakathi kwamadrayivu amabili, ishintshana phakathi kwawo. Inzuzo ukusebenza kokufunda/ukubhala okuthuthukisiwe ngoba amadrayivu amabili asebenza ngasikhathi sinye. Lokhu kudumile kuma-laptops emidlalo noma kuma-laptops abadali abeka phambili ukulayisha okusheshayo kanye nokudluliselwa kwamafayela amakhulu.
Kodwa-ke, ingozi ibalulekile: akukho ukuphindaphinda. Uma idrayivu eyodwa yehluleka, yonke idatha ku-RAID 0 array ingalahleka. Ngakho-ke, i-RAID 0 iphephile ngemikhuba yokusekela ngokulondoloza ehlelekile (isb., efwini noma kudrayivu yangaphandle).
Izinzuzo:
– Ukusebenza okuphezulu (ikakhulukazi emithwalweni emikhulu elandelanayo)
– Umthamo ophelele = kuhlanganiswe wonke amadrayivu
Ukushoda:
– Ingozi enkulu yokulahleka kwedatha uma enye yama-drive ihluleka
- Ukubuyiselwa kwedatha kunzima kakhulu kune-drive eyodwa
2) I-RAID 1 (Ukufanisa) - ukugxila kokuphepha kwedatha
I-RAID 1 iphinda idatha: okuqukethwe yidrayivu yokuqala neyesibili kuyafana. Uma i-SSD eyodwa yehluleka, i-laptop isengasebenza kwenye i-SSD (kuye ngokuthi isetshenziswe kanjani), futhi idatha ihlala iphephile.
Izinzuzo:
- Ukuphindaphinda okuphezulu ukuvimbela ukulahleka kwedatha ngenxa yokwehluleka kwedrayivu
- Kufanelekela idatha ebalulekile yomsebenzi
Ukushoda:
– Umthamo osebenzayo uyingxenye kuphela (ama-SSD amabili e-1 TB enza i-1 TB iyonke)
– Ukusebenza ngokuvamile akuthuthuki kakhulu (ngezinye izikhathi ukufunda kungaba ngcono, kodwa ukubhala kulandela inqubo yokubukisa)
3) I-RAID 5/10 - ayivamile kuma-laptop
I-RAID 5 idinga okungenani ama-drive amathathu, kanti i-RAID 10 idinga okungenani ama-drive amane, okwenza kube nzima ukuyithola kuma-laptop ngenxa yokulinganiselwa kwesikhala nesikhala. Amanye ama-laptops azinikele emsebenzini noma izinhlelo ze-modular angase akwazi ukwenza lokhu, kodwa lezi yizimo ezingavamile.
I-Hardware RAID vs i-software RAID kuma-laptop
Empeleni, i-RAID kuma-laptops ivame ukuhamba ngezindlela ezimbili:
1. “I-Firmware/Chipset RAID” (evame ukubizwa ngokuthi i-hardware RAID)
Ama-laptop amaningi asekelwe ku-Intel ake anikeza izici ezifana ne-Intel RST (Rapid Storage Technology), eyayivumela ukucushwa kwe-RAID nge-BIOS/UEFI. Nakuba ngokuvamile ibizwa ngokuthi i-hardware RAID, ezinhlelweni eziningi zesimanje lo mqondo ubizwa ngokunembe kakhulu ngokuthi "i-firmware-assisted RAID."
2. Isofthiwe ye-RAID
Izinhlelo zokusebenza ezifana ne-Windows (Storage Spaces), i-Linux (mdadm), noma izixazululo zezinkampani zangaphandle zingadala i-RAID kusetshenziswa isofthiwe. Lokhu kunenzuzo yokuba nezimo futhi kungaxhomeki kakhulu kwi-chipset, kodwa ngezinye izikhathi kungadinga ukucushwa okuningiliziwe kanye nokucabangela ukuhambisana ngesikhathi sokuqalisa.
Kuma-laptop, ukukhetha okungcono kakhulu kuvame ukunqunywa ukwesekwa komkhiqizi. Uma i-laptop yakho inikeza izinketho ze-RAID ku-BIOS/UEFI futhi ufuna i-RAID yedrayivu yesistimu (idrayivu yokuqalisa), ikhambi elakhelwe ngaphakathi lomkhiqizi ngokuvamile liyilona elisebenziseka kakhulu. Uma i-RAID ingeyama-drive edatha kuphela, i-software RAID ingaba inketho eguquguqukayo kakhudlwana.
Umthelela we-RAID ekusebenzeni kwangempela
Abantu abaningi bacabanga ukuthi i-RAID 0 ihlala iphinda kabili ijubane le-SSD. Eqinisweni, ukusebenza kuncike ezintweni eziningi: uhlobo lwe-SSD, inani lemizila ye-PCIe etholakalayo, imikhawulo ye-bandwidth ye-chipset, kanye nohlobo lomsebenzi.
– Ekudlulisweni kwamafayela amakhulu (ngokulandelana), i-RAID 0 inganikeza intuthuko ebonakalayo.
– Ngokufinyelela okungahleliwe, ikakhulukazi ngaphansi kwemithwalo elula, ukuthuthuka kungase kungabi kukhulu kangako ngoba ukubambezeleka nezici zama-NVMe SSD anamuhla sekuvele kushesha kakhulu.
– Uma izikhala ezimbili ze-M.2 zabelana ngomzila noma zidlula ngomzila ofanayo we-chipset, ukwanda komthamo kungase kukhawulelwe ukwakheka kwe-laptop.
Ngakolunye uhlangothi, i-RAID 1 igxile kakhulu kwezokuphepha. Nakuba ukusebenza kokufunda kungathuthuka kancane ngezinye izikhathi ngoba uhlelo lungafunda kwenye yamadrayivu "alungele" kakhulu, lesi akusona isizathu esiyinhloko sokukhetha i-RAID 1.
Ukulinganiselwa kanye nezingozi ze-RAID kuma-laptop
Ngaphambi kokuthatha isinqumo sokusebenzisa i-RAID kwi-laptop, naka izinto eziningana ezibalulekile:
1. I-RAID ayithathi indawo yesipele
I-RAID 1 ivikela ukwehluleka kwedrayivu, kodwa ayivikeli ekususweni kwamafayela, i-ransomware, ukonakala kwedatha, noma ukwehluleka kwesistimu yokusebenza. Ukusekela ngokulondoloza kusadingeka.
2. Ubunzima bokululama
Uma kuvela inkinga yomlawuli, kuvela isibuyekezo se-BIOS esiyinkinga, noma kwenzeka ukufuduka kwebhodi lomama, kungaba nzima ukulibona i-RAID array. Kwezinye izinhlelo zokusebenza, ukuhambisa i-array kwenye idivayisi akulula.
3. Ukusetshenziswa kwamandla nokushisa
Ama-SSD amabili e-NVMe asebenzayo angakhuphula ukusetshenziswa kwamandla kanye namazinga okushisa. Kuma-laptop amancane, lokhu kungathinta ukugoqa noma impilo yebhethri.
4. Ukutholakala kwezikhala zokugcina izinto
Ama-laptop amaningi anikeza isikhala esisodwa se-M.2. I-RAID ewusizo ingenzeka kuphela kuma-laptop anezikhala ezimbili noma ngaphezulu ze-M.2.
Ubani ofanele ukusebenzisa i-RAID kwi-laptop?
I-RAID kwi-laptop inengqondo kakhulu ku:
– Abadali bokuqukethwe abavame ukudlulisa amafayela amakhulu evidiyo futhi badinga isivinini sokudlulisa esisheshayo (i-RAID 0, enama-backups aqinile).
– Ochwepheshe abaphethe idatha ebalulekile futhi abafuna ukuvikelwa ekuhlulekeni kwe-SSD (RAID 1).
– Abasebenzisi bama-laptop base-Workstation abadinga ibhalansi yokusebenza nokuthembeka, ikakhulukazi emsebenzini ongenakuphazamiseka.
Ngakolunye uhlangothi, kubasebenzisi abavamile abasebenzisa ukuphequlula, umsebenzi wasehhovisi, kanye ne-multimedia kuphela, i-RAID ivame ukunganikezi izinzuzo ezifanele ubunzima. I-NVMe SSD eyodwa, esezingeni eliphezulu ivame ukwanela.
Amathiphu okukhetha nokusebenzisa i-RAID kwi-laptop
Uma ucabanga nge-RAID, amathiphu alandelayo angasiza:
– Qiniseka ukuthi i-laptop iyayisekela ngempela i-RAID (hlola imininingwane esemthethweni kanye nemenyu ye-BIOS/UEFI).
– Sebenzisa ama-SSD ohlobo olufanayo kanye nomthamo ukuze uthole imiphumela emihle kakhulu, ikakhulukazi ku-RAID 0 kanye ne-RAID 1.
– Naka uhlelo lokupholisa lwe-laptop yakho—Ama-NVMe SSD angashisa ngokushesha, kanti ama-SSD amabili asho umthombo wokushisa ophindwe kabili.
– Lungisa isu lokusekela: okungenani 3-2-1 (amakhophi amathathu edatha, imidiya emibili ehlukene, eyodwa endaweni ehlukile).
– Buyekeza i-firmware ye-SSD kanye ne-BIOS ngokucophelela; yenza kanjalo ngemva kokwenza ikhophi yasenqolobaneni, njengoba ukushintsha izilungiselelo zesitoreji kungaba yingozi.
Isiphetho
Ubuchwepheshe be-RAID kuma-laptop buyisisombululo esikhangayo kubasebenzisi abadinga ukusebenza okwengeziwe (RAID 0) noma ukuphepha kwedatha (RAID 1). Nakuba kungadingeki kuwo wonke umuntu, i-RAID ingaba isengezo esiwusizo kuma-laptop athile—ikakhulukazi lawo anezikhala ezimbili ze-NVMe SSD kanye nokusekelwa kokucushwa kwe-BIOS/UEFI. Kodwa-ke, kubalulekile ukuqonda ukuthi i-RAID ayithathi indawo yesipele futhi ingangeza ubunzima nezinkinga zokuhambisana ezingaba khona.
Ngokuqonda okulungile, i-RAID ingasiza i-laptop yakho ukuthi isebenze ngokushesha noma ngokuphephile, kuye ngezidingo zakho. Ukukhetha okungcono kakhulu ekugcineni kuncike ezintweni eziza kuqala kuwe: kungakhathaliseki ukuthi uphishekela isivinini esiphezulu noma ubeka phambili ukuvikelwa kwedatha ngenkathi usebenza usohambeni.
