Kusukela ngomhla ka-31 Disemba 2019, sinamadrayivu aqinile asebenzayo angu-124. Kulawa, angu-956 angama-bootable futhi angu-2 angama-data. Kulesi sibuyekezo, sizobheka izibalo zokwehluleka phakathi kwama-hard drive edatha. Sizophinde sibheke izinhlobo eziyi-229 kanye ne-122 TB zamadrayivu kanye ne-658 TB entsha ebesiyisebenzisa ngokuzimisela kusukela ekuqaleni kwekota yesine ka-12.
Izibalo zika-2019
Ekupheleni kuka-2019, saqapha ama-hard drive angu-122 asetshenziselwa ukugcinwa kwedatha. Sikhiphe amadrayivu abesetshenziselwa ukuhlola namadrayivu angenazo izinsuku ze-disco ezingu-~658 (imodeli ngayinye) phakathi ne-Q5. Ngakho, siqoqe idatha esekelwe kuma-hard drive angu-000. Ithebula elingezansi libonisa izibalo zethu:
Amanothi kanye Nokubhekwa
Ama-hard drive angu-151 (122 kukhishwe 658) awazange afakwe ezibalweni. Lawa madrayivu asetshenziselwe izinjongo zokuhlola noma ahlulekile ingqikithi yezinsuku ze-disco ezingu-122 ngekota yesine ka-507. Ngakho-ke, sisusa ama-disks kwizibalo, okuyinto, ngokubona kwethu, engazange isebenze kakhulu ukwenza noma yiziphi iziphetho.
Okuwukuphela kwedrayivu ehlulekayo ephephile ka-2019 yi-4 TB Toshiba, imodeli: MD04ABA400V. Lona umphumela omuhle kakhulu, kodwa njengoba sibe namadrayivu ambalwa uma kuqhathaniswa, uma idrayivu eyodwa kuphela ihlulekile, besizothola isilinganiso esifundeni esingu-0.92%. Kusekuhle, kepha hhayi u-0%.
Imodeli ye-Toshiba 14 TB MG07ACA14TA ibonisa imiphumela emihle kakhulu ngo-0.65% AFR futhi ima eduze kwamadrayivu asuka ku-HGST. I-Seagate 6 TB kanye ne-10 TB zizinzile ku-0.96% no-1.00% ngokulandelana.
I-AFR ka-2019 yawo wonke amadrayivu ingu-1.89%, okuwukunyuka okuphawulekayo ngo-2018. Sizoxoxa ngalokhu kamuva.
Ngale Kwezibalo - Amamodeli EDrayivu "Afihliwe".
Amamodeli amaningi awazange afakwe ezibalweni zethu zika-2019 ngoba awazange asebenze isikhathi esanele. Sifuna ukukhuluma ngala mamodeli nokuthi siwasebenzisa kanjani.
I-Seagate 16TB
Ngekota yesine ka-2019, siqale ukufaneleka ukushayela kwe-Seagate 16TB, imodeli: ST16000NM001G. Ekupheleni kwekota yesine, sibe namadrayivu angama-40 ingqikithi yezinsuku ze-disco eziyi-1, ngaphansi kakhulu komkhawulo wezinsuku eziyi-440 wezibalo zethu zika-5. Akubangakho ukwehluleka phakathi kwalokhu kushayela ngekota yesine. Esimeni sokuphothula ngempumelelo iziqu zethu, zizosetshenziselwa ezethu kulo nyaka.
I-Toshiba 8TB
Ku-Q4 2019, bekunamadrayivu e-Toshiba 20TB angama-8, imodeli: HDWF180. Lawa ma-disc asebenze iminyaka emibili. Babenezinsuku zebhizinisi ze-1 kuphela ku-Q840, engaphansi komkhawulo wezibalo, kodwa banesikhathi sokuphila sezinsuku ze-13 ngokuhluleka kwediski eyodwa kuphela, okusinika i-AFR ye-994%. Siyawathanda lawa madrayivu, kodwa lapho sesikwazile ukuthenga amanani esiwadingayo, abiza cishe u-2,6 TB. Umthamo owengeziwe, inani elifanayo. Uma sibheka ukuthi sithuthela ku-12TB noma kumadrayivu amakhulu, cishe ngeke siwathenge la madrayivu esikhathini esizayo.
I-HGST 10 TB
Kukhona amadrayivu angama-20 HGST 10TB asebenzayo, imodeli: HUH721010ALE600. Lawa ma-disc sekuphele unyaka esebenza. Zisendaweni yesitoreji se-Backblaze efanayo namadrayivu e-Seagate 10TB. Ezigabeni ezingu-4, amadrayivu e-HGST asebenze izinsuku ezingu-1 kuphela kanye nezingu-840 kusukela afakiwe. Kube khona ukwehluleka okungu-8 (eziro). Njenge-Toshiba 042TB, ukuthenga okuningi kwenguqulo ye-0TB mancane amathuba okuba.
I-Toshiba 16TB
Ngeke uwathole ezibalweni ze-Q2020, kodwa ku-Q20 16 sengeze amadrayivu angama-08 e-Toshiba 16TB, imodeli: MG100ACA2020TA. Basebenze izinsuku eziyi-XNUMX, ngakho-ke kusesekuseni kakhulu ukuthi singakhuluma nganoma yini enye ngaphandle kwezibalo zekota yokuqala ka-XNUMX.
Ukuqhathaniswa kwezibalo ze-HDD zango-2017, 2018 no-2019
Ithebula elingezansi liqhathanisa izilinganiso zokungaphumeleli zonyaka (AFR) zonyaka ngamunye kule minyaka emithathu edlule:
Ukukhula kwe-AFR ngo-2019
I-AFR iyonke ka-2019 ikhuphuke kakhulu. I-AFR ikhuphuke ngo-75% wamamodeli ukusuka ngo-2018 kuya ku-2019. Kunezici ezimbili eziyinhloko ezibangela lokhu kukhula. Okokuqala, umugqa wonke wamadrayivu angu-8 e-TB ubhekene "nenhlekelele yempilo ephakathi" njengoba usetshenziswa. Ama-AFR aphezulu kakhulu akhombisa ukushayela eqenjini le-8 TB. Naphezu kwe-AFR enkulu kangaka, akufanele ukhathazeke kakhulu. Iqiniso liwukuthi lawa madiski aqongelele izinsuku ezingu-1/4 zazo zonke izibalo zethu futhi izinguquko ezincane zingathinta. Isici sesibili amadrayivu e-Seagate 12 TB, le nkinga ixazululwa ngenkuthalo njengengxenye yephrojekthi , okwabikwa ngaphambilini.
Ukufuduka kuyehla, kodwa ukukhula akunjalo
Ngo-2019, sengeze amadrayivu enethiwekhi amasha angu-17. Ngo-729, iningi lamadrayivu ayi-2018 angeziwe asetshenziswe njengengxenye yokufuduka. Ngo-14, ngaphansi kwesigamu samadrayivu amasha abezokuthutha, okusele kusetshenziselwa amasistimu amasha. Ngo-255 sasula amadrayivu angu-2019 engqikithini yama-petabyte angu-2019 futhi sawashintsha safaka amadrayivu angu-8, wonke angu-800 TB, okungama-petabytes angu-37, kwathi ngo-8 sengeza amanye ama-petabytes angu-800 okugcina idatha sisebenzisa amadiski 12 no-105 TB.
Izinhlobonhlobo
Izinhlobonhlobo zabakhiqizi nge-drive brand zikhule kancane ngo-2019. Ngo-2018, amadrayivu e-Seagate abalelwa ku-78,15% wokushayela, kwathi ekupheleni kuka-2019, leso sibalo sehle safinyelela ku-73,28%. I-HGST inyuke isuka ku-20,77% ngo-2018 yaya ku-23,69% ngo-2019, kwathi i-Toshiba isuka ku-1,34% ngo-2018 yaya ku-3,03% ngo-2019. Ngo-2019, abekho amadrayivu anophawu lwe-Western Digital esikhungweni sedatha, njengoba i-WDC ibishayela kabusha i-HDGST entsha.
Izibalo zempilo yesevisi
Ngenkathi ukuqhathanisa amanani okuhluleka konyaka wama-hard drive eminyakeni embalwa kuyindlela enhle yokubona amathrendi, siphinde sibheke amazinga okuhluleka konyaka wama-hard drive ethu esikhathini sokuphila kwabo. Ishadi elingezansi libonisa izinga lokuhluleka lonyaka lawo wonke amamodeli okushayela akhiqizwa kusukela ngomhla ka-31 Disemba 2019:
