    Vszerda SA3120C 20 Port PCIe SATA Expansion Card, SATA III 6Gbps, ASM1064 | PCIe 3.0 x1, Ports 16: up to 207.5MB/s each, Ports 115: up to 41.5MB/s each, NAS & PC builds

    • 20-PORT SATA EXPANSION CARD: Adds 20 SATA III (6Gbps) drives to your desktop at once, turning one PCIe x1 slot into a 20-bay storage pool for unRAID, TrueNAS, ZFS, Proxmox or Windows Storage Spaces software RAID. Hardware RAID is not supported.
    • 41.5MB/S ON EVERY PORT: PCIe 3.0 X1 upstream runs at 8GT/s, and each of the 20 SATA ports delivers up to 41.5MB/s, so large multi-drive transfers, media libraries and backup jobs finish fast with no bottleneck.
    • NO DRIVER, WIDE COMPATIBILITY: Plug and play on Windows (except XP), Mac OS, Linux and NAS systems. Set SATA mode to AHCI in BIOS or UEFI before first install.
    • 20 BUILT-IN LED INDICATORS: A steady red LED means the drive is powered, a flashing LED means it is reading or writing, so you can check every SATA drive at a glance without opening the case.
    • FITS X1/X4/X8/X16 SLOTS, FULL KIT INCLUDED: Ships with 20 x SATA III cables (350mm/13.5in), 4 x 1:5 SATA power splitter cable. Pre-installed 12cm regular profile bracket, not available for mini/compact chassis installations.

    GLOTRENDS SA3120C - Add 20 SATA Drives to One PCIe Slot Running out of SATA ports? The GLOTRENDS SA3120C turns a single PCIe slot into 20 SATA III ports, powered by the ASM1064 controller plus 4x JMB575 port multipliers. It is the simple way to build a home NAS, a media server, or a large cold-storage and backup array - without replacing your motherboard. Plug the card into any PCIe X1, X4, X8 or X16 slot, connect your drives with the 20 included SATA III cables, add power with the 4 included 1-to-5 SATA splitter cables, and you are ready to go. No driver installation is needed on Windows, macOS, Linux or NAS systems such as TrueNAS and Unraid. 20 built-in LEDs show each drive's status at a glance: solid red for power, blinking for active read/write. All ports support AHCI mode and hot-swapping. Bandwidth guide:the PCIe 3.0 X1 upstream provides a shared 8GT/s. SATA ports 1-20 support up to 41.5MB/s per drive - ideal for HDDs, surveillance footage, media libraries and backups. Please note:this card does not support booting an operating system (OS boot), does not support hardware RAID (use software RAID or your NAS system's storage pool), and is not compatible with Windows XP. A full-height bracket is pre-installed; it does not fit slim or compact chassis.
