    Reviewed in Italy on February 20, 2024
    Recensione per il 22TB.
    Disco affidabile, Western Digital e' garanzia di qualita', questa serie GOLD ha delle caratteristiche uniche: grande cache di 512 Megabytes, tecnologia OptiNAND per massimizzare la capacita', Armorcache per la protezione dei dati in caso di uno spegnimento improvviso, il disco e' immerso in elio che lo rende silenziosissimo e permette bassi consumi, ha una lunga garanzia di 5 anni, e la velocita' e' straordinaria, pensate leggendo da SSD scrive stabilmente senza cambi repentini di velocita' a circa 240 Mega/secondo (vedere foto).

    ATTENZIONE per evitare di ordinare un disco piu' piccolo di quanto serve, dovete notare che WD indica la capacita' dei dischi in modo diverso da come la indica Windows:
    1 Terabyte secondo WD (che rispetta il "S.I.") sono 10^12 bytes cioe' 1.000.000.000.000 bytes,
    ma Windows e tutti i computer usano il Tebibyte, spesso indicandolo erroneamente come TB.
    1 Tebibyte sono 2^40 bytes cioe' 1.099.411.627.776 bytes. Allora, per ottenere la capacita' REALE moltiplicheremo la capacita' di WD per il rapporto di quei due lunghi numeri in bytes, che fa 0,9 circa.
    Facendo un esempio: nel mio caso 22TB * 0,9 = 20TiB. Leggermente meno ma tutto regolare. Infatti
    5TB diventano 4,5TiB
    10TB diventano 9TiB
    15TB diventano 13.5TiB
    20TB diventano 18TiB
    Quindi piu' aumentate le dimensioni, piu' aumenta la differenza tra la capacita' dichiarata da WD
    e la capacita' reale indicata da Windows. Fate molta attenzione quando ordinate onde evitare sorprese!
