Ready for 4 TB upgrades

The Ace A55 is a 2.5 inch SATA internal SSD built with 3D NAND flash and SLC cache technology. It targets laptop and desktop owners who want a straightforward capacity increase without changing drive bays. The 7 mm height fits ultrabooks and standard notebooks alike.

SATA connector and slim profile

A standard SATA interface means the drive drops into any 2.5 inch bay or caddy with no adapter required. The 7 mm z-height clears thin chassis while the 50 g weight keeps portable systems light. Shock resistance rated at 1500 G and vibration tolerance at 20 G protect data during daily transport.

Cool and quiet operation

With no moving parts the SSD runs silently and produces minimal heat under normal workloads. Sequential reads reach 500 MBps and writes reach 450 MBps while drawing little power from the system. An MTBF of 1500000 hours reflects the endurance expected from the SLC cache design.

商品問答

Does the SATA III interface on this Ace A55 4TB drive cap real-world throughput at 500 MBps read and 450 MBps write?

Yes. The SATA III link on this Ace A55 4TB SSD is rated for up to 500 MBps sequential read and up to 450 MBps sequential write, so those figures are the practical ceiling for sustained transfers.

Will the 7.0 mm height of this 2.5" Ace A55 4TB SSD fit my ultrabook or slim laptop bay?

The drive measures 7.0 mm thick in the standard 2.5" form factor, matching the slim 7 mm bay found in most ultrabooks and thin laptops.

When cloning my old drive to this Ace A55 4TB SSD, what step do people often miss that leaves the new drive unbootable?

After cloning, many forget to set the new SSD as the first boot device in the UEFI/BIOS, so the system keeps trying to start from the original drive.
