8 Port PCIe x1 SATA 3.0 Expansion Card with ASM1064+JMB575 Chips, PCI Express SATA III Controller Adapter, Includes 8 SATA Data Cables & Low Profile Bracket for Desktop HDD SSD NAS

This 8-port PCIe x1 SATA 3.0 expansion card adopts mature ASMedia ASM1064 main controller cascaded with JMB575 port multiplier chipset, efficiently expanding 8 high-speed SATA III ports to solve insufficient native motherboard SATA interfaces. Each SATA port delivers up to 6Gbps transfer speed, compatible with all 2.5" / 3.5" SATA HDD, SSD and optical drives, supporting single hard disk up to 20TB and massive combined storage capacity.

It features a standard PCIe Gen3 x1 bus, which can be inserted into any spare PCIe slot of mainstream Intel & AMD motherboards from ASUS, MSI, Gigabyte, ASRock. Built to AHCI 1.4 standard, it supports Native Command Queuing (NCQ), drive hot swap and system boot from connected SATA storage, ideal for multi-disk storage arrays and surveillance NVR/DVR equipment.

Equipped with a large-area aluminum heatsink, the card quickly dissipates heat generated by dual chips under heavy read-write loads without extra fan noise. Two mounting brackets are pre-packaged: full-height standard bracket for regular tower PCs and low-profile half-height bracket for small form factor SFF desktops. The package comes with 8 dedicated SATA data cables for instant assembly without extra purchases.

Fully plug-and-play on Windows XP/7/8/10/11, all mainstream Linux distributions and macOS systems with simple driver installation. Perfect for DIY NAS, video editing workstations, surveillance recording hosts, data backup servers and office PCs requiring large-scale storage expansion.
