- Ukubaluleka kokukhetha amadrayivu e-NAS aqinisekisiwe uma kuqhathaniswa namadrayivu edeskithophu avamile.
- Amasu okucushwa kwe-RAID kanye nokusetshenziswa kwezinhlelo ze-hybrid ukulinganisela izindleko kanye nesivinini.

Ukusetha iseva yesitoreji esinamathiselwe kunethiwekhi (i-NAS) kungenye yezinqumo ezinhle kakhulu ongazenza ukuhlela impilo yakho yedijithali. Kodwa-ke, abantu abaningi benza iphutha lokukhetha ama-drive, becabanga ukuthi noma iyiphi iyunithi efanelana ne-bay izokwenza. Iqiniso liwukuthi inhliziyo ye-NAS yakho yi-hard drive, futhi ukugcina izithombe ezimbalwa zomndeni akufani nokusetha isikhungo se-multimedia esisebenza amahora angama-24 ngosuku, izinsuku eziyi-7 ngesonto.
Ukuze ugweme ukwenza iphutha, kubalulekile ukuqonda ukuthi i-NAS akuyona ikhompyutha enkulu yedeskithophu; iyidivayisi eyenzelwe ukutholakala njalo nokufinyelela ngasikhathi sinye ngabasebenzisi abaningi. Ukukhetha ubuchwepheshe obungalungile kuyingozi ohlelweni oluhamba kancane noma, okubi nakakhulu, ukulahlekelwa amafayela akho ngoba idrayivu ayikwazanga ukusingatha umthwalo womsebenzi. Ake sihlukanise konke okudingeka ukwazi ukuze uthenge unolwazi.
Ubuchwepheshe bokugcina: i-HDD, i-SSD noma i-NVMe?
Emakethe yanamuhla, sisebenzisa ubuchwepheshe obuthathu kakhulu. Ama-HDD, noma ama-hard drive omshini, yiwona asebekhulile. Asebenza ngama-plate ajikelezayo nama-head okufunda/ukubhala, okwenza abe ashibhile kakhulu nge-terabyte ngayinye. Ayindlela enengqondo yokukhetha uma udinga ukugcina idatha eningi kakhulu, njengemitapo yama-movie ye-4K noma ama-backups amakhulu, njengoba enikeza amandla angaphezu kwe-18 TB ngamanani afanele.
Ngakolunye uhlangothi, sinama-SSD, angenazo izingxenye ezihambayo, ashesha kakhulu futhi amelana kakhulu nokushaqeka. Alungele ukusebenzisa izinhlelo zokusebenza ngqo kusuka ku-NAS noma ukuphatha amafayela amancane avulwa futhi avaliwe njalo. Ngaphakathi kwalesi sigaba kukhona ama-NVMe drive, asebenzisa isikhombikubona se-PCIe ukufeza isivinini esimangalisayo, okwenza abe ithuluzi eliphelele lochwepheshe bevidiyo noma abathandi bemidlalo abangakwazi ukumelana nezikhathi zokulayisha ezisheshayo.
Umehluko omkhulu: Ama-hard drive edeskithophu vs. ama-NAS drive
Yilapho iningi labaqalayo liphambuka khona. I-hard drive ye-PC ejwayelekile yenzelwe ukuthi ivulwe futhi icishwe kanye noma kabili ngosuku. Ngakolunye uhlangothi, i-NAS drive yakhelwe ukusebenza ngokuqhubekayo , iphatha imisebenzi yokukhomba kanye nokuxilonga ngemuva ngenkathi ulele. Ngaphezu kwalokho, ama-drive athile e-NAS ane-firmware elungiselelwe izindawo ze-RAID, okuvimbela uhlelo ukuthi lungazikhiphi ngenxa yamaphutha esikhathi sokuphendula.
Elinye iphuzu elibalulekile ukudlidliza. Uma ufaka amadiski amane noma amahlanu endaweni encane ebiyelwe, ukunyakaza kweyodwa kuthinta amanye. Ama-NAS drive afaka izinzwa zokudlidliza ezijikelezayo ezikhokhela lo mphumela, ezivimbela ikhanda lokufunda/lokubhala ukuthi lingashintshi kanye nezinga lokwehluleka ukuthi likhuphuke kakhulu. Ukusebenzisa ama-hard drive edeskithophu ku-NAS kufana nokudlala i-roulette yaseRussia ngedatha yakho.
Izilungiselelo zesitoreji kanye nokuvikelwa kwedatha
Ukuze i-NAS yakho ibe usizo ngempela, udinga ukucabangela indlela yokuhlela amadiski. Ukusebenzisa i-RAID (i-Redundant Array of Independent Disks) kukuvumela ukuthi uqoqe amadrayivu amaningi ukuze wandise umthamo noma ukuphepha. Isibonelo, uma ufuna i-redundancy ephelele , ungahlela amadiski ukuze ngalinye libe yikhophi eqondile yelandelayo; ngaleyo ndlela, uma elilodwa lehluleka, awulahlekelwa yi-byte eyodwa. Kodwa-ke, khumbula ukuthi kulezi zilungiselelo, umthamo ophelele awuyona ingqikithi yamandla amadiski; udela isikhala ukuze uthole ukuthula kwengqondo.
Uma unesabelomali esincane kodwa ufuna isivinini, ukusetha okuhlanganisiwe kuyindlela okufanele uhambe ngayo. Kuhilela ukusebenzisa i-HDD yokugcina izinto eziningi kanye ne-SSD encane njenge-cache. Ngale ndlela, i-NAS igcina amafayela asetshenziswa njalo kudrayivu esheshayo, ikunikeze impendulo esheshayo yesistimu ngaphandle kwezindleko zokugcwalisa iseva yonke ngama-SSD.
Indlela yokubala umthamo kanye nokusebenza ngokusekelwe ekusetshenzisweni
Ungathengi indawo yokugcina ngenxa nje yalokho. Uma ugcina amadokhumenti nezithombe ezimbalwa kuphela, i-1 noma i-2 TB izokwanela kakhulu. Kodwa uma usungene ezweni lokukhiqizwa kwamavidiyo e-4K , lungela ukudinga i-8 TB noma ngaphezulu. Elinye icebo ukubala usayizi wamafayela akho amanje bese wengeza imajini engu-20% yokukhula kwesikhathi esizayo, njengoba i-100% full drive iba kancane kakhulu futhi ingasebenzi kahle.
Ngokusebenza, bheka i-RPM (ukuguquguquka ngomzuzu). Ama-drive angu-5400 RPM athule futhi asebenzisa amandla amancane, afanele i-NAS egumbini lakho lokuphumula. Uma ubeka phambili isivinini sokudluliselwa njalo kwamafayela amakhulu, khetha ama-drive angu-7200 RPM, noma ngabe anomsindo womshini obonakala kakhulu.
Amathiphu okugcina okufakwa okuhlala isikhathi eside
Ungayinaki ihadiwe ezungeze ama-drive akho. Ukuhamba komoya okusebenza kahle kubalulekile; uma ama-drive eshisa kakhulu, isikhathi sawo sokuphila sincishiswa kakhulu. Ngaphezu kwalokho, i-UPS ( Uninterruptible Power Supply) ibalulekile . Ukuphela kukagesi okungazelelwe ngenkathi i-NAS ibhala idatha kungonakalisa uhlelo lwamafayela noma kulimaze i-RAID array, kuguqule ama-drive akho abizayo abe ama-paperweights ayinkimbinkimbi kakhulu.
Khumbula ukuthi i-RAID ayiyona ikhophi egciniwe. Ngisho noma ungasebenzi kahle, uma ususa ifayela ngephutha noma uthola igciwane, ushintsho luzophindaphindwa kuwo wonke amadiski. Ngakho-ke, umthetho wegolide uwukugcina ikhophi yangaphandle ehlukile njalo , kungaba kwenye i-hard drive exhunywe nge-USB noma efwini.
Isihluthulelo seseva ephumelelayo sisekubekeni phambili ukuthembeka kunentengo esheshayo, ukukhetha amayunithi aqinisekiswe yi-NAS, ukuhlela isikhala ngokuya ngokukhula kwedatha, nokuqinisekisa ubuqotho besistimu ngokupholisa okuhle kanye nokuvikelwa kukagesi.
Umbhali oshisekayo ngomhlaba wamabhayithi nobuchwepheshe ngokujwayelekile. Ngiyathanda ukwabelana ngolwazi lwami ngokubhala, futhi yilokho engizokwenza kule bhulogi, ngikubonise zonke izinto ezithakazelisayo kakhulu ngamagajethi, isofthiwe, ihadiwe, izitayela zobuchwepheshe, nokuningi. Inhloso yami ukukusiza ukuthi uzulazule emhlabeni wedijithali ngendlela elula nejabulisayo.
