\u010cvrsti diskovi nastavljaju osvajati tr\u017ei\u0161te, no unato\u010d tome, tradicionalni HDD-ovi se i dalje dobro dr\u017ee. \"Klasicima\" jo\u0161 nije vrijeme za muzej, budu\u0107i da je i dalje prakti\u010dno pohranjivati velike koli\u010dine informacija upravo na HDD diskovima. <\/p>\n

Prvo se postavlja pitanje cijene \u2014 dovoljno je usporediti tro\u0161ak SSD-a i HDD-a od jednog terabajta pa navi\u0161e. Po cijeni jednog SSD-a od 2 TB mo\u017eete kupiti \u010dak \u010detiri sli\u010dna HDD-a. Zna\u010dajan argument, sla\u017eete se!<\/p>\n

Drugo, klasi\u010dni tvrdi diskovi su se tijekom svih ovih godina prilagodili zahtjevima tr\u017ei\u0161ta: postali su br\u017ei, jednostavniji i prakti\u010dniji. O jednom od primjera \u0107emo danas govoriti. Ovo je klasi\u010dna verzija modernog HDD diska \u2014 Seagate ST2000DM008<\/b>.<\/p>\n

\"Pregled<\/a><\/noindex>
\n<\/a><\/noindex>
\nTvrdi disk koji razmatramo pripada seriji Barracuda koja ne treba dodatnu prezentaciju. Njegov kapacitet iznosi 2 terabajta. To je jedan od najpopularnijih formata danas: jedan terabajt ugra\u0111ene memorije mnogima vi\u0161e nije dovoljan jer su AAA videoigre i video sadr\u017eaj u posljednje dvije godine zna\u010dajno 'dobili na te\u017eini'. Prosje\u010dni dvostruki film u 4K formatu zauzima do 20 gigabajta, dok Far Cry 5 mo\u017ee dose\u0107i i do 50 GB.<\/p>\n

S druge strane, diskovi s pravim velikim kapacitetom (na primjer, Seagate ST14000VX0008 od 12 \u2014 14 TB) jo\u0161 uvijek su preskupi za ku\u0107nu upotrebu i prvenstveno su namijenjeni videonadzoru. Dakle, 2000 gigabajta predstavlja zlatnu sredinu za ve\u0107inu suvremenih ku\u0107nih ra\u010dunala.\u00a0<\/p>\n

\nModel Seagate ST2000DM008 nije tako jednostavan kao \u0161to se mo\u017eda \u010dini na prvi pogled. U obitelji HDD diska Barracuda ima najve\u0107u brzinu prijenosa podataka. Osim toga, disk se mo\u017ee pohvaliti impozantnim kapacitetom predmemorije od 256 MB. Drugim rije\u010dima, pred nama je jedan od najbr\u017eih 'dvica' na tr\u017ei\u0161tu, pri \u010demu to nikako ne odra\u017eava na njegovoj cijeni. Pogledajmo glavne tehni\u010dke specifikacije.<\/p>\n

Dizajn Seagate ST2000DM008 je klasi\u010dan: dobro poznata klasi\u010dna Barracuda koju prepoznajete ve\u0107 izdaleka po prepoznatljivom vizualnom identitetu. Standardna monta\u017ea omogu\u0107ava jednostavnu instalaciju bez potrebe za neprikladnim na\u010dinima fiksacije \u2014 ugradnja diska traje minimalno vremena.<\/p>\n

\"Pregled
\n
\nSkladi\u0161ni ure\u0111aj opremljen je sa dvije glave i jednom plo\u010dom, stoga nije prete\u017eak: samo 415 grama. Uz to, ku\u0107i\u0161te Seagate ST2000DM008 je tanje od mnogih konkurenata: debljina iznosi 20,2 milimetra. To povoljno utje\u010de na rad cijelog ra\u010dunala, na primjer, na ventilaciju unutar sistemske jedinice.<\/p>\n

\"Pregled
\n
\nNazna\u010dena brzina pisanja i \u010ditanja za Seagate ST2000DM008 iznosi 220 MB\/s. Maksimalna brzina prijenosa podataka vanjskog su\u010delja je 600 MB\/s. Podr\u017eava se posebna tehnologija MTC (multi-tier cache), koja optimizira podatkovne tokove i pobolj\u0161ava ukupnu u\u010dinkovitost sustava. Dodajmo tome zna\u010dajnu ke\u0161 memoriju i brzinu okretanja od 7200 okretaja u minuti \u2014 i dobivamo dobar izbor za aktivnu ku\u0107nu upotrebu po umjerenoj cijeni.<\/p>\n

Kao \u0161to vidite, Seagate ST2000DM008 pokazuje izvr\u0161ne rezultate u testovima i potpuno je u skladu sa navedenim specifikacijama. To zna\u010di da je idealan za ku\u0107nu upotrebu, poput kombinacije \u201eSSD za sistem + HDD za pohranu podataka\u201c. Zahvaljuju\u0107i visokoj (za tvrde diskove) brzini \u010ditanja i pisanja, ure\u0111aj se mo\u017ee s uspjehom koristiti u radu s multimedijskim softverom poput Adobe Premiere i Vegas Pro, kao i za igre. Dodatna prednost je nizak nivo buke: \u010dak i nekoliko HDD-a pri stalnom optere\u0107enju radi gotovo bez zvuka.<\/p>\n
