HAT PCIe vers SATA 2 canaux \u2014 donne du vrai stockage \u00e0 ton Raspberry Pi 5<\/span><\/h4>\n<\/div>\n
\n

Le Raspberry Pi 5 est le premier mod\u00e8le \u00e0 embarquer un vrai slot PCIe Gen3 x1. Ce HAT Waveshare exploite ce port pour ajouter <\/span>2 emplacements SATA<\/span><\/strong> \u00e0 ta carte, et transforme ton Raspberry Pi en petite base de stockage capable d’accueillir de vrais disques durs ou SSD.<\/span><\/p>\n<\/div>\n

\n

Pourquoi choisir le SATA plut\u00f4t que l’USB ?<\/span><\/h4>\n<\/div>\n
\n

Sur un Raspberry Pi, on branche souvent un disque externe en USB pour \u00e9tendre le stockage. Mais l’USB a ses limites :<\/span><\/p>\n<\/div>\n

\n
    \n
  • D\u00e9bit partag\u00e9 entre les ports<\/span><\/li>\n
  • Latence plus \u00e9lev\u00e9e<\/span><\/li>\n
  • Gestion moins fine des disques en usage intensif<\/span><\/li>\n<\/ul>\n<\/div>\n
    \n

    En passant par le PCIe et un vrai contr\u00f4leur SATA d\u00e9di\u00e9, tu contournes ces limites \u2014 id\u00e9al pour un mini-NAS, un media center, ou un serveur de sauvegarde perso.<\/span><\/p>\n<\/div>\n

    \n

    Caract\u00e9ristiques techniques<\/span><\/h4>\n<\/div>\n
    \n
      \n
    • 2 ports SATA III<\/span><\/strong>, jusqu’\u00e0 <\/span>6 Gbit\/s<\/span><\/strong> par canal<\/span><\/li>\n
    • Connexion via <\/span>slot PCIe Gen3 x1<\/span><\/strong><\/li>\n

    • Gestion de la <\/span>file d’attente NCQ<\/span><\/strong> (Native Command Queuing) pour optimiser les lectures\/\u00e9critures<\/span><\/li>\n

    • Compatible disques <\/span>5V et 12V<\/span><\/strong><\/li>\n
    • Formats <\/span>2,5 pouces et 3,5 pouces<\/span><\/strong><\/li>\n
    • Ne prend pas en charge le M.2<\/span><\/strong><\/li>\n<\/ul>\n<\/div>\n

      Ce que \u00e7a change concr\u00e8tement<\/span><\/h4>\n<\/div>\n
      \n

      Performance.<\/span><\/strong> Deux canaux ind\u00e9pendants \u00e0 6 Gbit\/s permettent de brancher deux SSD pour un montage rapide, ou un disque 3,5″ <\/span>+ un SSD 2,5″ pour du cache. Bonne base <\/span>aussi pour tester <\/span>un RAID logiciel <\/span>maison.<\/span><\/p>\n<\/div>\n

      \n

      Consommation.<\/span><\/strong> La <\/span>gestion des \u00e9tats <\/span>d’\u00e9nergie r\u00e9duit la <\/span>conso quand les disques <\/span>sont inactifs \u2014 utile pour <\/span>un montage qui tourne 24h\/24.<\/span><\/p>\n<\/div>\n

      \n

      Compatibilit\u00e9 disques.<\/span><\/strong> Tu peux <\/span>recycler un vieux disque dur 3,5″ de PC <\/span>de bureau (souvent en 12V) <\/span>ou installer un SSD 2,5″ r\u00e9cent <\/span>(souvent en 5V).<\/span><\/p>\n<\/div>\n

      \n

      \u26a0\ufe0f Point <\/span>important avant d’acheter<\/span><\/h4>\n<\/div>\n
      \n

      Les disques <\/span>3,5″ et certains mod\u00e8les 12V<\/span><\/strong> n\u00e9cessitent une <\/span>alimentation externe d\u00e9di\u00e9e<\/span><\/strong> pour le <\/span>HAT \u2014 l’alimentation native du <\/span>Raspberry Pi 5 ne suffit pas. V\u00e9rifie <\/span>la fiche technique de ton disque avant <\/span>de valider ta commande.<\/span><\/p>\n<\/div>\n

      \n

      Ce que <\/span>cette carte ne fait pas<\/span><\/h4>\n<\/div>\n
      \n

      Ce HAT est <\/span>100% SATA<\/span><\/strong>, il ne g\u00e8re pas le format <\/span>M.2 \/ NVMe. Si ton projet vise du NVMe, <\/span>il te faut une autre carte d’extension <\/span>d\u00e9di\u00e9e.<\/span><\/p>\n<\/div>\n

        Installation<\/span><\/h4>\n<\/div>\n
        \n

        Le HAT se fixe <\/span>directement sur le connecteur PCIe du <\/span>Raspberry Pi 5, sans c\u00e2blage ni <\/span>adaptateur interm\u00e9diaire. Une fois <\/span>install\u00e9, les deux ports SATA sont <\/span>reconnus nativement par le syst\u00e8me.<\/span><\/p>\n<\/div>\n
