Compact tower for Mini-ITX NAS builds

The iStarUSA S-35-B5BK is a black aluminium-and-steel tower chassis designed for Mini-ITX motherboards. It targets builders who need dense 3.5-inch drive storage in a small footprint, such as home NAS or backup servers. The case includes five hot-swap bays and a single internal 2.5-inch mount.

Five hot-swap bays limited to 6.0 Gb/s SATA/SAS

Each front bay accepts a 3.5-inch drive and connects through a backplane that supports 6.0 Gb/s SATA and SAS interfaces. The single expansion slot and two front USB 2.0 ports restrict add-in cards and high-speed peripherals. One 120 mm fan provides the only active cooling included.

Five 3.5-inch drives plus one 2.5-inch SSD

The chassis comfortably holds five full-size hard drives for multi-terabyte arrays while the internal 2.5-inch bay adds room for an OS SSD. Builds requiring more than five 3.5-inch drives, additional expansion cards, or redundant cooling will exceed the available bays, slots and fan mounts.

Questions about this item

Should I choose the version with five 3.5" hot-swap bays or the single internal 2.5" bay for my storage build?

The chassis provides five 3.5" hot-swap bays for main storage and one internal 2.5" bay for an OS drive or cache, so both are available together rather than as alternatives.

What does the 6.0Gb/s SATA/SAS support mean once drives are installed in the hot-swap bays?

Each hot-swap bay connects to a 6.0Gb/s SATA or SAS backplane, so installed drives run at up to 6.0Gb/s provided the motherboard or controller also supports that speed.

Which interface standard do the hot-swap bays use and what does it cap in practice?

The bays use a 6.0Gb/s SATA/SAS interface, capping each drive at 6.0Gb/s maximum throughput when paired with a compatible host controller.
