Doesn't work great with iMac running El Capitan. It tends to block the computer from going to sleep mode and doesn't seem to ever want to go to sleep itself either. I don't know what could be the cause and I don't have the time to figure it out FYI I have 3 external hard drives from the same line of...

非常抱歉,我认为只有写母语中文才能将我的感受写出来。 我做摄影17年了,这款硬盘可以将浏览图中的照片可以很快的流畅的显示出了,打开大文件也非常快。 愉快的网购! 谢谢!

LaCie drives rarely fail, so are better than most others I have bought. These also work just as expected with no problems. Also easy to set up.

Lacie's proven HD reliability is again unmatched. We use these HD's at my production company and they have never failed. Beyond reliability they also offer a large number of plugins including FIrewire 800, which has been particularly helpful with some of our older systems.

So far so good. this drive is a n upgrade for my full 1Tb drive I love Lacie Products they are so reliable

Love a good bit of gear, and this drive is certainly one of those items. It sits beautifully on its stand, taking up very little desk space, and runs quietly, and quickly delivering data as I need it. I've never had a hiccup with it, and I am thoroughly pleased.

I've been using LaCie hard drives for the last 9 years, and their hard drives are second to none. The d2 line is my favorite. Stylish and functional at the same time. Goes well with the Apple line of products.

After plugging in the Quadra it was easy for me to configure the automatic backup. Now the drive does its job, and when it's not in use it powers itself down. The transfer speeds are great, especially with USB 3.0. Overall, I'm pretty happy with this device.

    I have used this brand of backup drive now for over 8 years. I have two other drives which I have managed to fill up. They are not on constantly and have been good so far. There is a fan that is run to keep the drive cool. Easy to use. Drag and drop or hook up for automatic back up from your laptop.

I got this product because my other backup drive is out of space. Rather than deleting the data, I have to create a new backup area. I decided to go for this model, the LaCie d2 Quadra as it has lived up to its reputation with other products.
