\"Upgradeaz\u0103
\n
\nExist\u0103 oameni care prefer\u0103 s\u0103 foloseasc\u0103 componente de calitate din segmentul corporate \u00een via\u021ba de zi cu zi. Ei doresc s\u0103 fie siguri c\u0103 SSD-ul lor nu se va defecta brusc din cauza unei c\u0103deri de tensiune sau amplificarea scrierii<\/a><\/noindex> \u00een timpul desc\u0103rc\u0103rii zilnice a unor torrent-uri uria\u0219e 4K pe o parti\u021bie NTFS fragmentat\u0103 cu dimensiunea clusterului de 4K<\/a><\/noindex> sau \u00een timpul unei noi compil\u0103ri Gentoo din surse.<\/p>\n

Desigur, aceste temeri se materializeaz\u0103 rar \u00een practic\u0103, \u00eens\u0103 este foarte pl\u0103cut s\u0103 folose\u0219ti un SSD cu Power Loss Protection (1<\/a><\/noindex>, 2<\/a><\/noindex>, 3<\/a><\/noindex>), care are practic un ciclu de scriere aproape infinit. \u0218i chiar \u0219i atunci c\u00e2nd capacitatea sa devine insuficient\u0103 pentru sarcinile curente, el poate fi folosit ca un stick USB sau ca un disc suplimentar, d\u0103ruit sau v\u00e2ndut.<\/p>\n

\u00cen acest articol este prezentat o list\u0103 de SSD-uri corporate cu o capacitate de 1.92TB, care au devenit acum accesibile la pre\u021bul SSD-urilor de consum (< $300), dar care au un ciclu de scriere de 2 Petabyte \u0219i mai mult.
\n<\/a><\/noindex>
\nDeci, datorit\u0103 recentului colaps al pre\u021burilor la SSD-uri, ne putem permite s\u0103 instal\u0103m mon\u0219tri server de mai multe terabytes \u00een PC-uri \u0219i laptopuri personale.<\/p>\n

Interfa\u021ba SATA III nu a mai evoluat de mult, astfel \u00eenc\u00e2t SSD-urile realizate pentru utilizare corporate acum c\u00e2\u021biva ani se potrivesc perfect pentru upgrade-ul laptopurilor sau desktopurilor cu interfa\u021b\u0103 SATA, dar pre\u021burile lor au sc\u0103zut semnificativ.<\/p>\n

Consider c\u0103 aceast\u0103 dimensiune de ~2TB este optim\u0103 pentru upgrade-ul unui sistem vechi:<\/p>\n

    \n
  1. Aceasta este dimensiunea maxim\u0103 acceptat\u0103 de MBR. A\u0219adar, dac\u0103 BIOS-ul dumneavoastr\u0103 nu suport\u0103 UEFI, atunci acesta este op\u021biunea dumneavoastr\u0103. Astfel, \u00eembun\u0103t\u0103\u021bi\u021bi subsistemul de stocare p\u00e2n\u0103 la limit\u0103 (relevant pentru laptopurile cu un singur disc).<\/li>\n
  2. Aceste discuri au o dimensiune a sectorului de 512 byte, ceea ce le permite s\u0103 fie utilizate cu orice software. Chiar \u0219i cu Windows XP.<\/li>\n<\/ol>\n

    \nPe l\u00e2ng\u0103 un ciclu uria\u0219 de scriere, SSD-urile SATA corporate se diferen\u021biaz\u0103 prin:<\/p>\n

      \n
    1. Protec\u021bie la c\u0103deri de tensiune. \u00cen caz de \u00eentreruperi de curent, condensatorii din tantal (rar ceramic) ofer\u0103 SSD-ului SATA suficient\u0103 energie pentru a scrie cache-ul, astfel \u00eenc\u00e2t FS-ul s\u0103 nu se corupe.
      \n\"Upgradeaz\u0103\n<\/li>\n
    2. Stabilitatea caracteristicilor de vitez\u0103. La cele de consum se folose\u0219te adesea cache SLC, iar dup\u0103 ce acesta e complet, viteza poate sc\u0103dea semnificativ.<\/li>\n
    3. Produc\u0103torii sorteaz\u0103 cristalele de memorie flash \u00een func\u021bie de calitate. \u00cen SSD-urile corporate sunt folosite cele mai bune.<\/li>\n
    4. Uneori se folose\u0219te memorie MLC \u00een loc de TLC mai ieftin\u0103, 3D-NAND TLC, QLC.<\/li>\n<\/ol>\n

      \nIat\u0103 o tabel\u0103 cu modele de SSD-uri de 2TB, care sunt accesibile ca pre\u021b (p\u00e2n\u0103 la 300 $). M-am uitat la pre\u021buri \u00een principal pe site-uri de licita\u021bii \u0219i pe site-uri de tip Avito. Dar unele dintre unit\u0103\u021bile enumerate pot fi cump\u0103rate \u0219i din magazine obi\u015fnuite la aproximativ 25% mai mult. Cu c\u00e2t un SSD este mai sus \u00een tabel\u0103, cu at\u00e2t pre\u021bul este mai avantajos.<\/p>\n

      \u00cen aceast\u0103 tabel\u0103 sunt SSD-uri nu doar cu MLC, altfel ar r\u0103m\u00e2ne doar 2 linii.<\/p>\n
