Ti diski so nam v\u0161e\u010d, vendar so, ko smo jih uspeli kupiti v \u017eelenih koli\u010dinah, postali enako dragi kot 12 TB. Ve\u010dja kapaciteta, enaka cena.

AFR se je pove\u010dal za 75 % modelov od leta 2018 do 2019. Za tem rastem stojita dva glavna dejavnika. Prvi\u010d, celotna linija trdih diskov s kapaciteto 8 TB se soo\u010da z 'krizo srednjih let' med uporabo. Najvi\u0161je AFR bele\u017eijo diski, ki spadajo v skupino 8 TB. Kljub takemu visokemu AFR ni treba pretirano skrbeti. Gre namre\u010d za to, da so ti diski akkumulirali 1\/4 dni od celotne na\u0161e statistike in najmanj\u0161e spremembe lahko vplivajo nanjo. Drugi dejavnik - seagateovi 12 TB diski, ta problem aktivno re\u0161ujemo v okviru projekta. <noindex><a rel=\"nofollow\" href=\"https:\/\/www.backblaze.com\/blog\/drive-stats-update\">migracija na 12 TB<\/a><\/noindex>, o katerem je bilo prej poro\u010dano.<\/p>\n<p><\/p>\n<h3 id=\"migraciya-zamedlyaetsya-a-rost---net\">Migracija se upo\u010dasnjuje, rast pa ostaja<\/h3>\n<p><\/p>\n<p>V letu 2019 smo dodali 17.729 novih omre\u017enih diskov. V letu 2018 je bila ve\u010dina od 14.255 dodanih diskov uporabljena v okviru migracije. V letu 2019 je bilo manj kot polovica novih shranjevalnikov namenjena migraciji, ostali pa so bili uporabljeni za nove sisteme. V letu 2019 smo umaknili 8.800 diskov v skupni vrednosti 37 petabajtov in jih zamenjali za 8.800 diskov, vsi po 12 TB, kar predstavlja pribli\u017eno 105 petabajtov, nato pa smo v letu 2019 dodali \u0161e 181 petabajtov za shranjevanje podatkov z uporabo diskov kapacitete 12 in 14 TB.<\/p>\n<p><\/p>\n<h3 id=\"raznoobrazie\">Raznolikost<\/h3>\n<p><\/p>\n<p>Raznolikost proizvajalcev po blagovnih znamkah shranjevalnikov se je nekoliko pove\u010dala v letu 2019.

Pri HGST se je pove\u010dal z 20,77 % v letu 2018 na 23,69 % v letu 2019, Toshiba pa se je pove\u010dala z 1,34 % v letu 2018 na 3,03 % v letu 2019.
