GLOTRENDS

GLOTRENDS SA3824A 24-port PCIe 3.0 X8 SATA expansion card

SKU CH-DWGA-AKC1C MPN SA3824A

Adds 24 SATA III 6 Gbps ports via a PCIe 3.0 x8 link, each delivering up to 277 MB/s for large storage pools

  • TypePCI Express to SATA Card

Option 24-port ,X8

  • Connect 24 SATA drives simultaneously via PCIe 3.0 X8 interface
  • Each SATA port delivers up to 277 MB/s bandwidth allocation
  • Four ASM1166 controllers provide 64 GT/s upstream throughput
  • Plug-and-play compatibility across Windows, Mac OS, Linux and NAS
  • Software RAID configuration supported on all major operating systems

24-port SATA expansion card

The GLOTRENDS SA3824A adds 24 SATA III 6Gbps ports through a PCIe 3.0 x8 link using four ASM1166 controllers. It is designed for desktop PCs, servers or NAS units that need to address many drives at once.

Compatibility check

The card occupies a PCIe x16 slot but operates at x8 electrical speed, so the slot must provide at least x8 lanes. No hardware RAID is supported; software RAID or storage pools must be configured in the operating system. The board does not support OS booting and Windows XP is not compatible.

Suitable for multi-drive storage

This suits builders creating large software RAID arrays or storage pools with up to 24 SATA drives on Windows, Mac OS, Linux or NAS platforms. Buyers who need hardware RAID acceleration, boot support from the card, or fewer than 24 ports should consider a different controller.

Questions about this item

Does the SA3824A come with SATA data cables or only the card and a mounting screw?

The package includes the SA3824A card and one mounting screw for the chassis. SATA data cables for the 24 ports are not included and must be purchased separately.

The card uses four ASM1166 controllers — how does that affect port count and bandwidth per port?

Each ASM1166 handles six SATA III ports, giving 24 ports total. The PCIe 3.0 X8 upstream link provides 8 GB/s, so each downstream port can reach about 277 MB/s.

With 24 drives attached, will the PCIe 3.0 X8 link become a bottleneck for sequential workloads?

The upstream bandwidth is 8 GB/s. If all 24 ports run at their 277 MB/s maximum simultaneously the aggregate demand matches the link, so sustained sequential traffic can saturate the bus.
