on Tuesday introduced a new 160GB version of its Portable Hard Drive and a 500GB version of its Pushbutton Hard Drive. The 160GB model is coming in February for $379, while the 500GB drive is coming in April — pricing on that drive wasn’t announced.
The 160GB Portable Hard Drive uses USB 2.0 and is Mac and PC-compatible. It draws power from the USB port and weighs less than a pound, using a 2.5-inch hard disk drive mechanism inside. The drive features shock-mounting and is clad in aluminum alloy. BounceBack Express software is included, to assist in backups.
The 500GB Pushbutton Backup Hard Drive uses eSATA to communicate with a host Mac or PC (with an equipped interface card), and can transfer data at up to 300 megabytes per second. As the name implies, the drive can back up the contents of the host computer with the push of a button on the outside of the case. Because it uses external serial ATA (eSATA), it can back up data up to five times faster than drives that use USB 2.0 or FireWire 400, according to Seagate.
