Tahkete ketaste turg j\u00e4tkab kasvu, kuid vaatamata sellele tunnevad traditsioonilised HDD-d end endiselt h\u00e4sti. \u201eKlassikad\u201d pole muuseumisse v\u00f5tmiseks veel valmis, kuna suurte andmemahtude salvestamine on endiselt mugav just HDD-de abil. <\/p>\n

Esimene k\u00fcsimus on hind \u2014 piisab, kui v\u00f5rrelda 1 TB ja suuremate SSD-de ja HDD-de hindu. \u00dche 2 TB SSD hinna eest saate osta lausa neli sama suurusega k\u00f5vaketast. T\u00f5sine argument, eks?<\/p>\n

Teiseks, klassikalised k\u00f5vakettad on k\u00f5ik need aastad kohandunud turu n\u00f5udmistega: nad on muutunud kiiremaks, lihtsamaks ja mugavamaks. \u00dchest sellisest n\u00e4itest r\u00e4\u00e4gime t\u00e4na. See on klassikaline variant modernsest HDD-salvestist \u2014 Seagate ST2000DM008<\/b>.<\/p>\n

\nKetas, mida me kaalume, kuulub Barracuda seeriasse, mis ei vaja tutvustamist. Selle maht on 2 terabaiti. See on \u00fcks populaarsemaid t\u00e4na saadaval olevaid formaate: 1 terabait sisem\u00e4lu ei piisa paljudele, kuna AAA-m\u00e4ngud ja videokonteinerid on viimase paari aasta jooksul oluliselt \u201ekaalu juurde v\u00f5tnud\u201c. Keskmine kahetunnine film 4K formaadis v\u00f5tab kuni 20 gigabaiti, samas kui n\u00e4iteks Far Cry 5 - kuni 50 GB.<\/p>\n

Teisest k\u00fcljest on t\u00f5eliselt suurte mahtudega (n\u00e4iteks Seagate ST14000VX0008 12 - 14 TB) kettad koduseks kasutamiseks veel liiga kallid ja m\u00f5eldud eelk\u00f5ige videovalve jaoks. Seega on 2000 gigabaiti enamikule kaasaegsetele kodu-PC-dele ideaalne keskmine lahendus.\u00a0<\/p>\n

\nSeagate ST2000DM008 mudel ei ole nii lihtne, nagu esmapilgul paistab. Barracuda HDD-perekonnas on sellel k\u00f5ige k\u00f5rgem andmeedastuskiirus. Lisaks saab k\u00f5vaketas uhkustada muljetavaldava vahem\u00e4lu mahuga \u2014 256 MB. Kokkuv\u00f5ttes on tegemist \u00fche kiireima \"kahesaja\" turul, samas kui selle hind ei peegelda seda sugugi. Vaatame p\u00f5hitehnilisi omadusi.<\/p>\n

Seagate ST2000DM008 disain on traditsiooniline: see on h\u00e4sti tuntud klassikaline Barracuda, mida tunned juba kaugelt m\u00f5nede kaubam\u00e4rgi v\u00e4rvikombinatsioonide j\u00e4rgi. Kinnitusdetailid on standardsed, ei ole vaja tegeleda kinnitusprotseduuride ja mitte t\u00fc\u00fcpiliste kinnitamisviisidega \u2014 ketta paigaldamine v\u00f5tab minimaalselt aega.<\/p>\n

\nSalvesti on varustatud kahte pead ja \u00fche plaadiga, seega pole see liiga raske: kokku 415 grammi. Samuti on Seagate ST2000DM008 korpus \u00f5hem kui paljuski konkurentsis: selle paksus on 20,2 millimeetrit. See m\u00f5jutab positiivselt kogu arvuti toimimist, n\u00e4iteks s\u00fcsteemi ventilatsiooni.<\/p>\n

\nSeagate ST2000DM008 v\u00e4ljakuulutatud kirjutamis- ja lugemiskiirus on 220 MB\/s. Maksimaalne andmeedastuskiirus v\u00e4lises liideses on 600 MB\/s. Toetatakse patenteeritud tehnoloogiat MTC (multi-tier cache), mis optimeerib andmevooge ja parandab s\u00fcsteemi \u00fcldist j\u00f5udlust. Lisame siia muljetavaldava vahem\u00e4lu ja p\u00f6\u00f6rlemiskiirus 7200 p\/min \u2014 ning saame hea valiku aktiivseks koduseks kasutamiseks, lisaks m\u00f5istlikule hinnale.<\/p>\n

Nagu n\u00e4ha, n\u00e4itab Seagate ST2000DM008 teste suurep\u00e4raseid tulemusi ja vastab t\u00e4ielikult esitatud omadustele. See sobib suurep\u00e4raselt koduseks kasutamiseks, n\u00e4iteks koosolekus \"SSD s\u00fcsteemile + HDD andmete salvestamiseks\". T\u00e4nu suurele (k\u00f5vakettade mastaabis) lugemise ja kirjutamise kiirusel on seadet edukalt v\u00f5imalik kasutada multimeedia tarkvara, nagu Adobe Premiere ja Vegas Pro, t\u00f6\u00f6ks ning ka m\u00e4ngimiseks. T\u00e4iendav eelis on madal m\u00fcra tase: isegi mitu HDD-d pideva koormuse all t\u00f6\u00f6tavad peaaegu vaikides.<\/p>\n

\nTuleb lisada, et Seagate Barracuda kogu mudelivalik sisaldab seadmeid, mille maht varieerub 500 GB-st kuni muljetavaldava 8 TB-ni, seega leiate salvesti igasuguste \u00fclesannete jaoks.
