USB 2.0 to SATA and IDE Adapter

The CoolGear USBG-124ASD connects SATA and IDE hard drives or optical drives to a computer through a USB 2.0 port. It supports 2.5 inch, 3.5 inch and 5.25 inch form factors including SATA I, SATA II and IDE ATA-66, 100 and 133 devices. The adapter is intended for data migration, drive recovery or temporary access by technicians and home users.

Sustained Transfer Behaviour

The JM20337 chipset limits throughput to the USB 2.0 maximum of 480 Mb/s, so large transfers run at that ceiling rather than the native drive speed. Mechanical drives will not saturate the link, but solid-state media will be bottlenecked by the interface during extended copy operations. The supplied power adapter feeds 3.5 inch and 5.25 inch units, while 2.5 inch drives draw bus power.

Installation and Common Issues

Driver installation is automatic on modern operating systems and the drive appears as a removable volume once connected. The cable length is under six feet, so the host port must be within reach of the work surface. A frequent problem is forgetting the external power brick for larger drives, which causes the device to spin down or disappear mid-transfer.

Questions about this item

How hot or noisy does the JM20337 chip get when the adapter runs all day?

The adapter has no fan; the JM20337 chip runs passively cooled and draws power from the USB 2.0 port for 2.5″ drives, so heat and noise stay minimal during continuous use.

Which power supply must I already own to run a 3.5″ or 5.25″ drive with this adapter?

The included high-output power adapter connects to mains power and provides the 12 V rail that 3.5″ and 5.25″ IDE or SATA drives require.

Will my older ATA-66, ATA-100 or ATA-133 IDE drives work through the USB 2.0 port on this adapter?

Yes — the JM20337 chip supports IDE ATA-66/100/133 drives from 1.8″ up to 5.25″, so legacy drives connect and transfer at USB 2.0 speeds.
