What is a refurbished device?
A refurbished device is a pre-owned item that has been restored to meet high-quality standards. At Reboot IT, we adhere to strict quality guidelines, ensuring that our refurbished products are not the same as used or secondhand items. We meticulously clean, test, and assess each device, replacing worn parts with high-quality components.
Unlike used items, which lack guarantees and rely solely on the seller's word regarding condition, refurbished devices come with assurance of quality and reliability.
What payment options are available?
We offer a variety of payment options to make your shopping experience as convenient as possible! You can pay using all major credit cards, Apple Pay, Google Pay, Shop Pay, Afterpay, Zip Pay, and PayPal. If you prefer, we also accept bank deposits and even cash for in-store purchases!
Vantec NST-D400S3 Dual Bay HDD SSD Dock USB 3.0 SATA 2.5" 3.5&...
We ensure secure processing of your payment information and do not retain or have access to your credit card details.
A certified refurbished dual-bay SATA docking station that takes two 2.5-inch or 3.5-inch drives at once and presents them to any computer over USB 3.0 at up to 5 Gbps. Supports SATA I, II and III hard drives and SSDs up to 8 TB per slot — 16 TB in total. Backed by a 12-month warranty from Reboot IT. Please note: the external power adapter is not included with this unit.
A dual-bay dock earns its place on a workbench. Recovering files from a pulled desktop drive, wiping a batch of decommissioned disks, imaging a laptop drive before a rebuild, or simply reading an old archive nobody can identify — all of it becomes a matter of dropping the drive into a slot rather than opening a chassis and finding a spare SATA port and power lead.
Because both bays mount independently, the second slot is what makes it genuinely useful. Source in one, destination in the other, and the copy runs through your operating system's normal file tools with both volumes visible in Explorer or Finder at the same time. Over USB 3.0 that runs at practical sustained speeds limited by the drives themselves rather than the interface — a mechanical 3.5-inch disk will saturate long before the 5 Gbps bus does.
Two limits worth stating plainly. First, this model has no standalone clone function: unlike Vantec's dedicated duplicator docks, it must be connected to a computer, and copying is done by the host OS rather than by a button on the dock. Second, it is a plain dock, not a RAID enclosure — the two bays are always independent volumes and cannot be spanned, mirrored or striped.

| Grade A — Excellent | Excellent to very good cosmetic condition. May carry light scratches or other minor blemishes from normal service. Fully tested and functionally as-new. |
| Grade B — Good | Good cosmetic condition with more visible wear, scuffing or marking to the casing. Function and performance are unaffected and testing is identical to Grade A. |
Cosmetic grading describes the casing only. Every unit, whatever its grade, is tested to the same standard and carries the same warranty.
Is a power adapter included?
No. This unit is supplied without its external power adapter, which is reflected in the price. The dock is mains-powered and will not operate on USB power alone, so you will need to source a compatible Vantec DC adapter before use.
Can it clone one drive to another without a computer?
No. The NST-D400S3 is a dock, not a duplicator — it must be connected to a computer, and copying is performed by your operating system. If you need button-press offline cloning, Vantec's dedicated HDD duplicator dock is the model to look for.
Can I use both bays at the same time?
Yes. Both drives mount simultaneously as two separate volumes over the one USB cable, so you can drag files directly between them.
What is the largest drive it supports?
8 TB per slot, for 16 TB across both bays. Both 2.5-inch and 3.5-inch SATA I, II and III drives are supported, including 2.5-inch SSDs.
Does it support M.2 or NVMe drives?
No. This dock is SATA only. M.2 SATA drives would need a separate adapter caddy, and NVMe drives are not compatible at all.
Can the two bays be set up as RAID?
No. The bays are always presented as independent volumes and cannot be spanned, mirrored or striped.
What is shipping and delivery like?
Shipping costs apply based on size and destination — rates are calculated at checkout. Orders placed before the daily cut-off are typically dispatched the same business day from our Melbourne warehouse.
This certified refurbished Vantec NexStar NST-D400S3 is supplied with a 12-month warranty covering hardware faults and defects in materials and workmanship. If the unit develops a fault within the warranty period we will repair or replace it, and our Melbourne-based support team can help you diagnose the issue first.
Reboot IT has specialised in professionally refurbished business IT equipment since 2001. Every unit is inspected, cleaned and functionally tested before listing — for this dock that means verifying both SATA bays with known-good drives, confirming USB 3.0 enumeration and transfer, and checking the LED indicators.

I was looking for an in-expensive all-in-one solution for my home office to replace my existing desktop and monitor. I found this EliteOne 800 on reboot IT for under $200. I wasn't sure what to expect. It arrived within two days!!!! I upgraded the RAM, replaced the HDD and installed Windows 11. This is unbeatable value and was the cheapest price online. Coupled with a 3-month warranty, Reboot IT are by far the best online refurbished retailer I have used. Awesome!
Great service. Product in great condition and exactly what i want. I wanted this for a specific purpose but i dont need to spend $900 on a new one.
Excellent work
