This article covers SilverStone 6ポートSATA Gen3 (6Gbps)Non-RAID PCI Express Gen3 x2 拡充カード SST-ECS06.

Overview

The SilverStone SST-ECS06 is a PCIe expansion card that adds six SATA 6Gbps ports to any desktop PC with a free PCIe slot. It uses an ASMedia ASM1166 controller in AHCI mode and connects via PCIe Gen3 x2, offering enough bandwidth for multiple mechanical drives or SATA SSDs. This card is an ideal solution for NAS builders, file server enthusiasts, or anyone who has run out of onboard SATA ports and needs a simple, cost-effective expansion.

Connectivity & Compatibility

The SST-ECS06 requires a PCIe Gen3 x2 or higher slot (x4, x8, x16 all work). It provides six SATA Gen3 (6Gbps) ports, each backward compatible with SATA 2 and SATA 1 drives. The card supports SATA port multiplier command-based switching and device sleep power management. It includes both full-height and low-profile brackets, making it suitable for most desktop cases. Note that this card offers no hardware RAID—it presents each drive individually to the OS, so you'll rely on software RAID or pooling solutions like Windows Storage Spaces, mdadm, or ZFS.

Product Info

Launched around 2021, the SilverStone SST-ECS06 is priced around ¥12,200 JPY (~$85 USD) from major retailers like . The package includes the card, a low-profile bracket, and a quick-start manual. The card carries a standard manufacturer warranty. Market positioning is solidly mid-range: it doesn't compete with hardware RAID cards in features, but its six-port capacity at this price point offers excellent value for users who just need more SATA ports without RAID complexity.

Best Use Cases

This card is best suited for: DIY NAS and home server builders: If your motherboard has only 4 or 6 SATA ports and you need more, adding this card gives you six extra ports in a single slot. Works well with TrueNAS, Unraid, or Windows Storage Spaces. Not recommended if you require hardware RAID5/6 with dedicated cache. Creative professionals with media archives: Videographers, photographers, and data hoarders who connect multiple hard drives for backup or active projects will appreciate the easy expansion. The PCIe Gen3 x2 link provides about 2 GB/s aggregate bandwidth—more than enough for a pool of HDDs. However, do not expect NVMe-level speeds on individual drives. * Breathe new life into older systems: If you have an older PC collecting dust, turn it into a file server by adding this card. The low power draw and sleep support make it suitable for 24/7 operation.
