Ukusukela nge-31 kaDisemba ka-2019, sine-124 esebenzayo ye-hard drives. Kwezi, i-956 ikwi-bootable kwaye i-2 yidatha. Kolu hlaziyo, siza kujonga izibalo zokungaphumeleli phakathi kwee-hard drives zedatha. Siza kuqwalasela kwakhona iinguqulelo ze-TB ezili-229 kunye ne-122 kunye ne-658 TB entsha, ebesiyisebenzisa ngokusebenzayo ukususela ekuqaleni kwekota yesine ka-12.
Iinkcukacha-manani zowama-2019
Ekupheleni kuka-2019, sibeke iliso kwii-hard drives eziyi-122 ezisetyenziselwa ukugcinwa kwedatha. Sisuse kwiidrive zokubala ezisetyenziselwe ukuvavanya kunye needrive ezingenayo ~ 658 iintsuku zokuqhuba (ngemodeli nganye) kwikota yesine. Ngaloo ndlela, siqokelele idatha esekelwe kwii-hard drives ze-5. Itheyibhile engezantsi ibonisa izibalo zethu:
Amanqaku kunye nemigqaliselo
Ii-hard drives ezili-151 (122 minus 658) azifakwanga kumanani-nkcazo. Ezi drives zisetyenziselwe ukuvavanywa okanye azizange zisebenze iintsuku ezingama-122 zokuqhuba ngekota yesine ka-507. Ngaloo ndlela, sisusa kwiidiski zezibalo, ngokombono wethu, azisebenzi ixesha elide ngokwaneleyo ukwenza naziphi na izigqibo.
I-drive kuphela engenazinkathazo ngo-2019 yi-4 TB Toshiba, imodeli: MD04ABA400V. Esi sisiphumo esihle kakhulu, kodwa kuba besinazo ezimbalwa kwezi drives, ukuba idrayivu enye kuphela ayiphumelelanga, ngesifumene umyinge omalunga ne-0.92%. Kusekuhle, kodwa akusekho 0%.
I-Toshiba 14 imodeli ye-TB ye-MG07ACA14TA ibonisa iziphumo ezilungileyo kakhulu nge-0.65% AFR kwaye imele ecaleni kwee-drives ezivela kwi-HGST. I-Seagate 6 TB kunye ne-10 TB zizinzile kwi-0.96% kunye ne-1.00%, ngokulandelanayo.
I-AFR ka-2019 yazo zonke iidrive yi-1.89%, engaphezulu kakhulu kunowama-2018. Siza kuxubusha oku kamva.
Ngaphaya kwezibalo - iimodeli zediski "ezifihliweyo".
Iimodeli ezininzi azifakwanga kwizibalo zethu zika-2019 kuba khange zisebenze ixesha elaneleyo. Sifuna ukuthetha ngezi modeli kunye nendlela esizisebenzisa ngayo.
Seagate 16 TB
Kwikota yesine ka-2019, saqala ukufumana i-Seagate 16 TB drives, imodeli: ST16000NM001G. Ekupheleni kwekota yesine, saba ne-40 drives, emele i-1 yeentsuku ze-disco, ngaphantsi kwe-440 yeentsuku zezibalo zethu ze-5. Akukho kusilela phakathi kwezi drives kwikota yesine. Emva kokugqiba ngempumelelo iziqinisekiso zethu, ziya kusetyenziselwa yethu kulo nyaka.
Toshiba 8TB
Kwi-Q4 2019 bekukho i-20 Toshiba 8 TB drives, imodeli: HDWF180. Ezi diski zasebenza iminyaka emibini. Kwikota yesine babeneentsuku zokusebenza ze-1 kuphela, ezingaphantsi komda wezibalo, kodwa baphila ubomi beentsuku ze-840 kunye nokungaphumeleli kwe-drive enye kuphela, kusinika i-AFR ye-13%. Siyazithanda ezi drives, kodwa xa siye sakwazi ukuzithenga ngokwemiyinge ebesiyidinga, zaqala ukuxabisa ukuya kutsho kwi-994 TB. Umthamo ongaphezulu, ixabiso elifanayo. Ukuthathela ingqalelo ukuba sifudukela kwi-2,6TB kunye needrive ezinkulu, kusenokwenzeka ukuba asizukuthenga ezi drives kwixesha elizayo.
HGST 10 TB
Kukho i-20 HGST 10 TB drives esebenzayo, imodeli: HUH721010ALE600. Ezi diski bezisetyenziswa ngaphezu konyaka nje. Bakwindawo yokugcina i-Backblaze efana ne-Seagate 10TB drives. Ngaphezulu kweekota ze-4, ii-drive ze-HGST zisebenze iintsuku ze-1 kuphela, kwaye ukususela ekufakeni - 840 8. Kwakukho ukungaphumeleli kwe-042 (zero). NjengakwiToshiba 0TB, ukuthenga ngaphezulu kwenguqulo ye-8TB akunakwenzeka.
Toshiba 16TB
Awuyi kuzifumana kwizibalo ze-Q2020, kodwa kwi-Q20 16 songeze i-08 Toshiba 16TB drives, Model: MG100ACA2020TA. Basebenze iintsuku ezili-XNUMX zizonke, ke kusesekuseni kakhulu ukuthetha ngayo nantoni na ngaphandle kwamanani ekota yokuqala ka-XNUMX.
Ukuthelekiswa kwezibalo ze-hard drive ze-2017, i-2018 kunye ne-2019.
Itheyibhile engezantsi ithelekisa iireyithi zokungaphumeleli zonyaka (AFR) kunyaka ngamnye kule minyaka mithathu idlulileyo:
Ukukhula kwe-AFR ngo-2019
Iyonke i-AFR ka-2019 inyuke kakhulu. I-AFR inyuke nge-75% yeemodeli ukusuka ngo-2018 ukuya ku-2019. Zimbini izinto eziphambili ezibangela oku kukhula. Okokuqala, wonke umgca we-8 TB uqhuba amava "engxakini yobomi" njengoko esetyenziswa. Ezona AFR ziphezulu ziboniswa ziidrive eziqukwe kwiqela le-8 TB. Nangona i-AFR ephezulu kangaka, akukho mfuneko yakukhathazeka kakhulu. Inyani kukuba ezi diski zisebenze i-1/4 yeentsuku zazo zonke izibalo zethu kwaye utshintsho oluncinci lunokubachaphazela. Into yesibini yiSeagate 12 TB drives, le ngxaki isonjululwa ngenkuthalo ngaphakathi kwiprojekthi , eyayixelwe ngaphambili.
Ukufuduka kuyacotha, kodwa ukukhula akunjalo
Ngo-2019, songeze iidrive zenethiwekhi ezintsha eziyi-17. Ngo-729, uninzi lwe-2018 drives ezongeziweyo zasetyenziswa njengenxalenye yokufuduka. Ngo-14, ngaphantsi kwesiqingatha seedrive ezintsha zenzelwe ukufuduka, kwaye ezinye zisetyenziselwa iinkqubo ezintsha. Ngo-255, siye sathatha umhlala-phantsi ii-2019 zokuqhuba ii-petabytes ezingama-2019 zizonke kwaye sazitshintsha ngee-8 zokuqhuba, zonke ii-TB ezili-800, ezimalunga ne-37 petabytes, emva koko ngo-8 songeze ezinye iipetabytes eziyi-800 zokugcina sisebenzisa umthamo we-TB we-12 kunye ne-105.
Okuninzi
Iindidi zabavelisi nge-brand brand ziye zanda kancinci ngo-2019. Ngo-2018, i-Seagate drives yenze i-78,15% ye-drives, kwaye ekupheleni kuka-2019, eli nani liye lehla laya kwi-73,28%. I-HGST inyuke ukusuka kwi-20,77% ngo-2018 ukuya kwi-23,69% ngo-2019, kunye ne-Toshiba ukusuka kwi-1,34% ngo-2018 ukuya kwi-3,03% ngo-2019.
Iinkcukacha-manani zobomi benkonzo
Ngelixa uthelekisa amaxabiso onyaka wokungaphumeleli kwi-hard drive kwiminyaka eliqela yindlela entle yokuchonga iintsingiselo, sikwajonga amazinga okusilela wonyaka kwii-hard drives zethu kubomi babo bonke. Itshathi engezantsi ibonisa izinga lokusilela lonyaka lazo zonke iimodeli zokuqhuba kwimveliso ukusuka nge-31 kaDisemba 2019:
