12-port PCIe SATA expansion card

The GLOTRENDS SA3112J adds twelve SATA III 6 Gbps ports through a single PCI Express 3.0 x1 slot, letting a desktop PC, server or NAS address up to twelve SATA drives at once. It uses two JMB575 and one ASM1064 controllers to provide AHCI mode for software RAID or storage-pool configurations, though hardware RAID is not supported and the card cannot boot an operating system.

Bundled cables and power splitters

Twelve SATA III data cables and three 1-to-5 SATA power splitter cables are included, so every drive port can be connected without sourcing extra parts. The splitters draw power from the system’s existing SATA power connectors, simplifying large drive deployments.

Suits high-density storage builds.

Builders who need many affordable SATA connections for bulk storage, ZFS pools or software RAID arrays will find the card practical. Users requiring a bootable controller, hardware RAID offload or full 6 Gbps per port simultaneously should consider other solutions.

Questions about this item

Will the JMB575 and ASM1064 controllers on the SA3112J need firmware updates or driver reinstallation over time?

The card uses plug-and-play AHCI mode on Windows, Mac OS, Linux and NAS; Windows 7 requires a one-time manual driver install from the maker's link, after that no further controller maintenance is expected.

Does the single PCIe 3.0 x1 link become the bottleneck before the twelve SATA III 6Gbps ports saturate?

Yes, twelve ports share one PCIe 3.0 x1 lane capped at 8Gbps, so combined throughput tops out around 1GB/s and individual drives cannot all hit 6Gbps simultaneously.

How much heat and power does the SA3112J add when all twelve drives run continuously?

The board has no onboard fan; heat comes only from the two JMB575 and one ASM1064 chips, and drive power is supplied externally through the three included 1:5 SATA splitter cables.
