Is it right for you?
Yes, if you want a quiet, high-bandwidth desktop enclosure to house up to four SATA hard drives or SSDs, bundled with SoftRAID Premium for advanced RAID 5 protection and proactive drive health monitoring.
Probably not, if you need a compact bus-powered drive for travel, or you want high-speed NVMe blade storage rather than SATA drives.
Using it
Installing drives. Unlock the front panel with the included key, loosen the thumbscrews to slide out each tray, and mount your 2.5-inch or 3.5-inch SATA drives using the provided screws. Slide the trays back in until seated firmly and lock the front door.
Connecting. Connect the included 0.7-metre Thunderbolt 5 cable from the host port to your Mac or PC, plug in the mains power lead, and launch SoftRAID to format and configure your RAID volume.
Warranty
OWC gives a 2-year limited warranty from the date of purchase against defects in materials and workmanship. Normal wear and tear, cosmetic damage (including scratches and cracks), accidental damage and misuse are not covered.
Questions
- Does it come with hard drives or SSDs installed?
- No. This is an empty DIY storage enclosure. You supply your own 2.5-inch or 3.5-inch SATA hard drives or SSDs.
- What RAID software is included?
- Includes 3 years of SoftRAID Premium access, allowing you to configure, manage, and proactively monitor RAID 0, 1, 4, 5, 6, 6+, and 10 volumes across Mac and Windows.
- Can I mix hard drives and SSDs?
- Yes. Each bay operates independently over SATA, allowing you to combine different drive capacities or media types in independent disk configurations.
- Can I daisy chain other devices?
- Yes. The secondary Thunderbolt 5 port supports up to 80Gb/s of daisy-chain bandwidth for up to five additional Thunderbolt or USB4 devices, or an external display up to 8K.
- Is accidental damage covered by the warranty?
- No. Accidental drops, physical damage, and cosmetic wear are not covered by the manufacturer warranty.
