OWC has introduced a new small form factor high performance, high redundancy DAS for the professional market. The ThunderBay 4 Mini incorporates 4 2.5-inch storage bays, allowing it to store up to 16 TB of data, and with OWC touting transfer speeds of up to 1.5 GB/s. The device is aimed at various creative professionals who need an ample amount of reliable storage space, but in a relatively small package.

The OWC ThunderBay 4 Mini DAS can accommodate four 2.5-inch/15.5 mm storage devices and is based on Intel’s JHL6540 (dual-port TB3) and ASMedia’s ASM1062 (PCIe 2.0 x2 => two SATA 6 Gbps bridge) controllers. Given constraints imposed by a SATA 6 Gbps interface and the ASM1062 chip, the ThunderBay 4 Mini can offer up to 1556 MB/s read/write performance when equipped with four SATA SSDs, or around 560 MB/s when populated with four Seagate’s 2.5-inch 4 TB hard drives. To ensure stable operation and consistent performance, the DAS comes equipped with a fan.

Layered on top of the hardware to provide both multi-disk performance and redundancy is OWC's SoftRAID software. OWC will offer the ThunderBay 4 Mini with either its SoftRAID XT or SoftRAID XT Lite software, depending on the model and required RAID level. The applications support both Apple macOS and Microsoft Windows operating systems, so the DAS is compatible with a wide variety of computers available today.

    @crimsonson: Great, thanks!

    TB would be the bottleneck in such a setup, which I don't think would make sense.

    You don't necessarily run them raid 0

    So, what you want is a NAS instead?

    Over WiFi?

    Over network?

    Not directly?

    That would be called a NAS

    I have several 4TB 2.5" drives in various mini-ITX computers, so I acknowledge they are useful little things. However if I wanted more than 4TB, a single 8TB 3.5" would seem smaller and more portable than this 4-bay box with 2 x 4tb 2.5" or even 3x 2tb 2.5". It seems rather niche and rather expensive.

    Also the prices.... My 4TB 2.5" drives cost around £80-100 each new. OK they're not RAID versions but the markup shouldnt be that much. Ditto a 2TB m.2 should be around £220-250.

    Actually if someone was able to create a m.2 box that gave 4 m.2 slots in the space of a fag packet, that would be pretty popular.

    The point of the box is that you have a RAID box you can move from system to system. Yes, you can add up a bunch of drives inside your computer that is cheaper and maybe faster but not quite easy to transport.
