The Iomega Rev 120GB Backup Drive, the third generation of the company's popular removable hard disk backup technology, is a compelling alternative for small businesses considering tape or other options for offsite backup and archiving.
Introduced in early April and available now, the Rev 120GB can read new, larger-capacity 120 GB disks thanks to a hard drive technology called perpendicular recording. This method stacks data vertically, or perpendicular to the disk instead of horizontally or parallel to the disk (also called longitudinal recording). The end result is that individual disks can hold a lot more data.

The first and second generation Rev drives use 35GB and 70GB capacity disks respectively. If you own an older Rev, take note: The new 120GB drive is backward compatible with the 70GB disks for reading data only – it can't write data to 70GB disks. It does not work at all with the even-older 35GB disks.
In the Rev system, the removable part is a compact cartridge with just the 2.5-inch disk platter and spindle motor. The cartridge is only 2.95 x 3.03 x 0.39-inches and weighs 2.58 ounces. The rest of the mechanics and electronics, including the shock-sensitive read/write heads, are in the drive unit, which means if you drop a disk, you don't have to worry about damaging your data.
The new drive comes in two workstation versions: an external USB 2.0 and an internal SATA. Both include one 120GB disk and Retrospect Express backup software from EMC. The USB version lists for $500, the SATA version for $480. (The Rev 70GB drive debuted at $600 in 2006.) Additional disks sell for $75 each or five for $325.
Iomega also offers backup kits, bundles designed for use with a server. They come with either USB or SATA interface – $700 or $680 – and include five 120GB discs and a version of CA’s more advanced BrightStor ARCserve Backup software with disaster recovery functionality.
With the price of the Rev products dropping and storage capacity increasing, Iomega claims it offer a lower total cost of ownership (TCO) than other backup solutions, including LTO, DAT and DLT tape, Blu-Ray optical discs and competing removable hard disk products.
According to Iomega’s calculations, over a five year period the Rev 120GB technology is 64 percent less expensive than DAT160, 67 percent less expensive than LTO1 and 53 percent less expensive than Blu-ray 50GB.
The company calculated TCO as the initial drive cost, plus initial cost of media (the disk or tape cartridge), plus the media replacement cost per year and labor cost to change the media, times five years.
The Rev 120 offers the advantage of a compact, lightweight cartridge you can take out and transport to another location to store backup or archive files offsite. Storing both types of files offsite is a good idea. If you keep your backups onsite, you risk losing critical data in the event of a fire or burglary.
Many fixed external hard drives are also small enough to transport offsite on a daily or weekly basis, but this is not a practical solution because hard drives are vulnerable to damage in transit. The Rev disks, once removed from the drive, are rugged and sealed to keep out dust and dirt.
Fixed external hard drives are a lot less expensive, though. (Iomega doesn’t include them in its TCO comparisons.) Name-brand 500GB drives sell for as little as $100 – or 20 cents per gigabyte. Initial cost per gigabyte for Rev, even if you buy one of the economical five-disk bundles, is more than $1. Fixed USB drives are slightly faster too, as we’ll see.
