  • I-HAMR (Ukurekhodwa kwezibuthe okusizwa ukushisa) ivumela idatha eyengeziwe ukuthi igcinwe kuma-hard drive ngokushisisa i-magnetic medium.
  • Lobu buchwepheshe kwandisa kakhulu ukuminyana kwesitoreji, nezibikezelo zokufinyelela ku-100 TB ngeyunithi ngayinye esikhathini esizayo.
  • Naphezu kwezinzuzo zayo, ibhekene nayo izinselele ezifana nokuphathwa kokushisa nokuthembeka, osekubambezele ukutholwa kwayo okwandile.
  • Kukhona ezinye izindlela ezifana ne-MAMR ne-SSD, nazo ezincintisanayo emakethe yokugcina izinto ezinomthamo omkhulu.

Buyini ubuchwepheshe be-HARM-3?

Ukuthuthuka kwesitoreji sedijithali kuholele ekudalweni kobuchwepheshe obusha obuhlose ukwandisa umthamo we-hard drive ngaphandle kokubeka engcupheni ukuthembeka. Kulesi simo, ubuchwepheshe be -HAMR (Heat-Assisted Magnetic Recording) buthuthukiswe njengesisombululo esisha sokwandisa ubuningi besitoreji. Njengoba izibikezelo zikhomba kuma-drive afinyelela ku- 100 terabytes , ochwepheshe abaningi bakubheka njengekusasa lesitoreji se-magnetic.

Kulesi sihloko, sizohlola ngokuningiliziwe ukuthi iyini i-HAMR , isebenza kanjani, yiziphi izinzuzo ezinikezayo, nokuthi yiziphi izinselele ebhekene nazo. Sizobona nokuthi iqhathaniswa kanjani nezinye ubuchwepheshe obusha emkhakheni wokugcina idatha.

Buyini ubuchwepheshe be-HAMR?

I-HAMR ubuchwepheshe bokuqopha obusebenzisa amandla kagesi asekelwa ukushisa obuvumela umthamo wokugcina idatha ophakeme kakhulu kuma-hard drive endabuko. Lokhu kufeza lokhu ngokusebenzisa i- laser efudumeza okwesikhashana ubuso bediski ngesikhathi esiqondile idatha ebhaliwe ngaso. Lokhu kuvumela ukusetshenziswa kwezinto ezizinzile kakhulu ngaphandle kokuphazamisa isivinini sokubhala, okuholela ekuxineni okuphezulu kwe-bit nge-inch yesikwele.

Umgomo oyinhloko we-HAMR uwukunqoba imikhawulo yobuchwepheshe bamanje besitoreji, obufana ne-Perpendicular Magnetic Recording (PMR) kanye ne-Tile Magnetic Recording (SMR), efinyelele umkhawulo wazo ngokuya ngokuminyana kwesitoreji.

Ubuchwepheshe be-HAMR busebenza kanjani

Buyini ubuchwepheshe be-HARM-0?

Ukuze uqonde ukuthi i-HAMR isebenza kanjani , kubalulekile ukwazi isakhiwo esiyisisekelo se-hard drive yendabuko. I-hard drive iqukethe amapuleti ajikelezayo ambozwe ungqimba lwezinto ezisebenza ngogesi, lapho idatha iqoshwa khona yikhanda lokubhala.

Inkinga ngobuchwepheshe bamanje ukuthi, njengoba ukuminyana kwedatha kukhuphuka, izinhlamvu zamagnetic ezibangela ukugcina ulwazi ziba zincane futhi zibe sengozini yokuphazamiseka kwangaphandle. Isixazululo esiphakanyisiwe se-HAMR ukusebenzisa izinto ezizinzile kakhulu ekushiseni ezivimbela ukulahleka kwedatha nokwenza kube lula ukubhala ngokusebenzisa ukushisa ngesikhathi esiqondile kusetshenziswa i-laser diode encane.

Inqubo ngokuningiliziwe imi kanje:

  • Un I-Near-field plasmonic transducer (NFT) igxilisa ukukhanya kwe-laser endaweni encane yediski.
  • Izinga lokushisa kuleso sifunda esithile likhuphuka isikhashana ngaphezu kwe Izinga lokushisa le-Curie kwempahla.
  • Ngenkathi indawo ishisa, inhloko yokubhala isebenzisa inkambu kazibuthe ukurekhoda idatha.
  • Ngokushesha ngemva kwalokho, isifunda siyaphola futhi ibhithi yedatha iyalungiswa, kuyaqinisekisa ukuzinza kwesikhathi eside.

Le nqubo yenzeka kuma-nanosecond futhi ivumela ukwanda kokuminyana kwesitoreji ngaphandle kokubeka engcupheni ukuthembeka kwediski.

Izinzuzo zobuchwepheshe be-HAMR

I-HAMR inikeza izinzuzo eziningana ngaphezu kobuchwepheshe bendabuko bokugcina amandla kazibuthe:

  • Umthamo wokugcina okhulisiwe: ikuvumela ukuthi ugcine idatha eyengeziwe endaweni efanayo, ngokuqagela kwe-hard drive kufika ku-100 TB.
  • Ukuzinza okukhulu kwedatha: Izinto ezisetshenziswa ku-HAMR zehlisa ukulahleka kolwazi okubangelwa ukuphazamiseka kazibuthe.
  • Izindleko eziphansi ngegigabhayithi ngayinye: Uma kuqhathaniswa nobuchwepheshe obufana nama-SSD, IHAMR inikeza inketho yokonga kakhulu yokugcina inqwaba.

Izinselele kanye nemikhawulo

Naphezu kwezinzuzo zayo, i-HAMR ibhekene nezinselele eziningana zobuchwepheshe nezentengiselwano:

  • Ukuthembeka kwesikhathi eside: Ukusetshenziswa kwama-lasers kanye nemijikelezo yokushisa nokupholisa eqhubekayo kungathinta ukuqina kwamadiski.
  • Ukuphathwa kokushisa: Ukuhlanganisa isistimu yokushisisa ibe umklamo osuvele uyinkimbinkimbi kwandisa ingozi yokwehluleka kokushisa.
  • Izindleko zokukhiqiza: ukukhiqizwa kwamarekhodi IHAMR Idinga izinto ezintsha nezinqubo, okwenza ukuthuthukiswa kwayo kubize kakhulu.

Ezinye izindlela ezisafufusa: i-MAMR ne-SSD

I-HAMR akuyona yodwa ubuchwepheshe obusathuthukiswayo bokuthuthukisa isitoreji sedatha. Ezinye izindlela ezithakazelisayo zifaka:

  • I-MAMR (Ukuqoshwa kweMagnetic okusizwa nge-Microwave): Esikhundleni sokushisisa indawo engaphezulu, i-MAMR isebenzisa ama-microwave ukuze inciphise amandla adingekayo ukuze kubhalwe idatha.
  • I-Solid State Drives (SSD): Nakuba ama-SSD enikeza isivinini esiphezulu kakhulu, asabiza kakhulu futhi anamandla aphansi uma kuqhathaniswa nama-hard drive.

Ikusasa le-HAMR nokwamukelwa kwayo embonini

Nakuba i-HAMR ingakatholakali kabanzi, abakhiqizi abanjengoSeagate bamemezele amamodeli abo okuqala okuhweba asebenzisa lobu buchwepheshe. Njengoba izindleko zokukhiqiza zincipha futhi izinkinga zobuchwepheshe zixazululwa, i-HAMR cishe iyoba yindinganiso yama-hard drive anamandla aphezulu ezikhungweni zedatha kanye nesitoreji sobungcweti.

Isidingo esiqhubekayo sendawo yokugcina izinto eziningi sizoqhuba ukuthuthuka kobuchwepheshe obufana ne -HAMR eminyakeni ezayo. Nakuba isabhekene nezinselele zobuchwepheshe, amandla ayo okuguqula imakethe yokugcina izinto awaphikwa. Njengoba kungenzeka ukuthi ifinyelele kumandla afinyelela ku- 100 TB eminyakeni ezayo, i-HAMR isalokhu ingumbangi oqinile wekusasa lesitoreji esinozibuthe.
