Standalone duplicator for two SATA drives

The Vantec NexStar JX NST-D258S3-BK is a dual-bay dock that clones SATA drives sector-by-sector without a host computer. It accepts 2.5 in and 3.5 in hard drives or SSDs up to 20 TB per bay and runs from a 12 V DC adapter. One-touch duplication starts with a single button press.

Suits archivists and technicians who need offline

Ideal for users who duplicate drives in any combination of HDD and SSD without installing software. Not suited for workflows that require hardware RAID, encryption acceleration, or network-attached storage features. Buyers who need active cooling for sustained heavy workloads should consider a fan-equipped enclosure.

USB 3.2 Gen 1 host interface for dock mode

When connected to a PC or Mac the unit acts as a dual-bay SATA dock over a single USB 3.2 Gen 1 link, supporting Windows 7 through 11, OS X 10.6 or later, and current Linux distributions. The standalone cloning function operates independently of this connection.

Questions about this item

Will the NST-D258S3-BK clone a 3.5 inch SATA drive from my older desktop onto a new 2.5 inch SSD?

Yes, the dock accepts both 2.5 and 3.5 inch SATA drives in either bay and can duplicate HDD to SSD, SSD to HDD or any other combination without a computer.

How do I know the sector-by-sector clone has finished correctly on the NexStar JX?

Press the clone button to start the one-touch duplication; the LED indicators show progress and confirm when the standalone sector-to-sector copy is complete.

Does the NST-D258S3-BK package include the 12 V power adapter and USB 3.2 Gen1 cable, or must I buy them separately?

The enclosure ships with a 12 VDC 3 A AC adapter and a USB 3.2 Gen1 cable for host connection; drives are not included.
