1 TB Constellation laptop drive

This 1 TB 2.5" SATA drive spins at 7200 RPM and includes a 64 MB cache. It is built for laptops or small-form-factor systems that accept a standard 2.5" internal drive. The Constellation line targets workloads that benefit from higher rotational speed. Hot-swap capability is supported where the host hardware allows it.

Installation notes

The drive fits any 2.5" SATA bay using the usual four mounting screws and a standard SATA data and power connector. No extra drivers are required for the SATA interface itself. The most common issue is a caddy or bracket that is too thick for the specific laptop chassis, so verify the bay depth before fitting. Hot-swap function only works if the laptop or enclosure explicitly supports it.

Compatibility check

Confirm that your system has a free 2.5" SATA port and that the BIOS or UEFI recognises drives of this capacity. Some older laptops limit addressable space, so check the manufacturer documentation for any capacity ceiling. Ensure the physical bay height matches a standard 2.5" drive; ultra-thin models may need a slimmer unit. Verify that the SATA controller mode (AHCI or RAID) is set as required by your operating system.

Questions about this item

How can I verify the Constellation drive is running at 7200 RPM after installation?

Use a tool such as CrystalDiskInfo or the BIOS SMART page to confirm the reported rotation speed matches 7200 RPM and that the SATA link is active.

What comes with the 9W5WV drive and what must I source separately?

The drive itself is supplied; you will need a 2.5" SATA data cable, a SATA power connection and a mounting bracket or caddy if your laptop bay requires one.

Which capacity of the Constellation line should I choose for a single-drive laptop upgrade?

The 1 TB model provides 1 TB of storage with a 64 MB cache and 7200 RPM speed, making it the only capacity offered in this listing.
