Reviews for LaCie 3TB d2 USB 3.0 Thunderbolt Series Hard Drive

This drive was very easy to setup. All I had to do was connect it with the included Thunderbolt cable to my iMac, and just follow the setup utility. This drive is now my new best friend. It hasn't skipped a beat since I configured it. It's quiet and has excellent speeds.

Out of the box it felt heavy and sturdy. I was excited to get 3TB and Thunderbolt speed. But, this hard drive did not perform at thunderbolt speeds. Not even close. All it did do however, was slow down my editing and to make matters worse its my only drive to corrupt and lose files. I knew I should have stuck with the G Tech. Back to the Apple Store I go to return this brick. I don't have time to mess with getting another one just to check if mine was a defect. It shouldn't happen in the first place. I'm just disappointed with the hassle.

Sorry LaCie- I teach at a middle school Mac lab where I have had five of your drives die on me over the past three years- 1 just this week broke down. Won't be buying!

2nd Lacie Drive in three years to bite the dust. Thank god for time machine

I am looking for a performance hard drive for my primary drive and can last for many years. This one is definitely looked hight quality and fast. It's easy to setup and will not generate too much heat. Performance is better than my internal hard drive in my Mac. The only reason I am giving only 4 stars is the noise, read/write is quiet but I mean the mechanical noise in general. There is a difference with the drive turned on or off particularly at night, the noise is more noticeable. Comparing to my cheaper LaCie Porsche Design hard drive (super quiet), this D2 drive is a lot noisier although it's not too annoying.

I am impressed with this 3T backup system using the TM feature in Mountain Lion.. The back up speed is very fast and smooth.. Other advantage is that it goes asleep with the ML sleep mode. The only issue I had was the faint humming noise coming from the constant disk whirling..Granted the unit was stored on my desk top.. I moved it below the top and now I barely hear it..The old WD system made noise like a rattling street car...

This works well as a Time Machine backup disk or as a scratch disk for video editing. The transfer speeds are great. If you want faster read/write times then grab something with flash storage instead, but for the average consumer this should work fine.

I like that it spins down and sleeps when the computer does, and particularly like that it also has a dedicated on/off switch unlike some other drives.

It looks great paired up with an iMac. The d2 line has rock solid performance and reliability and this seems to continue that trend.

Under Snow Leopard, Lion and Mt Lion this thunderbolt device sleeps with the system . Awakens with the system and copy speeds range between 130 megs/sec to 160.

Compared to the Little Big Disk it takes a few seconds to wind up after awake but no big deal. Does not slow the shutdown time of the system.

Only drawback is the one thunderbolt port, so must place at the end of the daisy chain.
