I need Firewire and USB 3.0 so I can use the drive for new and older systems. I was immediately impressed with everything about this product from packaging to build quality to setup and performance. This drive is very solid. It sits sturdy on the desk when I use the power switch. It runs smoothly and is quiet. I am ordering another identical drive as a backup for the backup. I have been using several smaller external drives believing it is safer in case a drive breaks down. But I have changed my opinion and will be using a pair of these 4GB drives and just use the smaller drives with my Macbook Pro.

Performs as advertised, limited to UBS 3.0 connectivity, requires power, blue light a little bright, does not overheat, power transformer is standard brick size, has LaCie Share function on start up so can be partitioned for both MAC OS and Windows, or reformatted for either. I use as a USB shared drive off my home router and works quickly-does not slow my network noticeably.

I needed another external hard drive to backup my iMac. Since I already own two other external hard drives from LaCie for several years and never had any problems, my choice was easy and I just stayed with LaCie. I'm very pleased with this hard drive.

I have an older iMac that does not support USB 3.0 or Thunderbolt, so I need drives that support FireWire 800. I have 5 of these drives, and use them for backing up my boot drive and storing pictures and video files. So far they work great.

The HD made it quickly and performs just as advertised. Great product!
