3.5" External Hard Drives

A hard disk drive (or HDD) is a high capacity device used for data storage. Data is written on the hard drive using magnetism. The size and purpose of HDDs vary, therefore choose one that best suits your individual needs.

Continue

Hard discs can basically be divided into the following categories:

  • Drives for PCs - for common work on a PC
  • Drives for NAS systems (Network Attached Storage) - drives for network devices that operate 24/7
  • Drives for surveillance systems - drives that continuously write data and operate 24/7
  • Drives for data centers
  • Drives for demanding applications (can be replaced with SSDs) - for gamers or graphic designers

NASInteligentné dátové úložiská QNAP: Aký NAS vybrať pre domácnosť? Spoločnosť QNAP vníma NAS ako niečo viac než len „obyčajné úložisko“. Aj preto nás teší, že vám môžeme ponúknuť atraktívny produktový rad diskových úložísk určených na domáce použitie. Tak ktoré si vyberiete?
Potrebujete naformátovať disk pre hernú konzolu, vytvoriť externý disk, ktorý bude spolupracovať s Windows aj MacOS, pripraviť flash disk na ďalšie použitie alebo potrebné doplniť nové úložisko do existujúcej zostavy? Podrobný návod, ako na formátovanie a všetko s ním...
Platňové disky už nemajú v počítačoch čo robiť. Sú pomalé, a navyše hlučné. Patria tak maximálne do NAS úložísk, a aj tam ich už pomaly nahrádzajú SSD disky. Nie je ale SSD disk ako SSD disk. Doba letí dopredu a SATA rozhraniu pomaly odzvonilo. Pekných pár rokov tu...
ArticleDefragmentácia a čistenie disku (PODROBNÝ NÁVOD) Naozaj len ťažko nájdete disk, na ktorom by neboli žiadne duplicitné či nadbytočné dáta. Tieto dáta nielen ukrajujú z dostupnej kapacity úložiska, ale tiež spomaľujú chod celého počítača. Raz za čas (napr. za štvrťrok) by ste preto mali svoj disk aspoň čiastočne...
Fotky, dokumenty alebo videá patria medzi to najcennejšie, čo vo svojom digitálnom živote máme. Poradíme vám, ako ľahko a elegantne vyriešiť zálohovanie dát. Stačí totiž chvíľka nepozornosti a vír vám všetko v priebehu niekoľkých okamihov nenávratne zašifruje. Kam...
Služba Seagate Rescue chráni vaše dáta v prípade, že dôjde k poškodeniu disku, napadnutiu vírusom, chybe softvéru alebo z iných dôvodov, ktorých následkom je strata dát. Ako v takom prípade postupovať, sa dozviete v našom článku.
