The 4TB d2 Professional USB 3.1 Type-C External Hard Drive from LaCie features a USB 3.1 Gen 2 Type-C port that’s compatible with Thunderbolt 3 devices. In case your system isn’t equipped with a Type-C port, it comes with a Type-C to Type-A adapter.
Inside is a Seagate BarraCuda Pro enterprise-class drive, which spins at 7200 rpm and offers data transfer rates of up to 260 MB/s. The drive is pre-formatted as exFAT, which allows for compatibility with both macOS and Windows systems. If you’re using the drive with only one operating system, you optimize the drive’s performance by reformatting it as NFTS for Windows or HFS+/APFS for macOS.
In addition to its warranty, this drive includes a five-year Rescue Data Recovery Services plan as well as a one-month membership to Adobe Creative Cloud All Apps plan.

Lightening fast speeds to back up my photography, and I feel good knowing backups are safe!

I had never spent any significant money on an external hard drive but I sure wish I had done this earlier. Not that these are the most expensive available but the difference between this and my older externals is night and day. Set up was easy.

For many years I’ve relied on LaCie’s external hard drives and will continue to do so as they’ve never failed me and I’ve never had a single issue with any of my drives.

Plug it in and it works just fine.

I like that it stands up, it feels extremely sturdy, and the form factor is compact. I’m just wondering why no power button? Is it about trying to keep a certain price point? I like to have something I can switch on and off, and having to fish around for the power cable is weird.

Received new in box drive which was inert. The power supply was OK but the drive would not power up. Had to deal with LaCie/Seagate’s warranty process to get a replacement drive. It took two weeks before I received a working drive. Their quality control needs some improvement.

The only HDs I’ve ever used throughout my career. I buy a new one every year and always have two on hand as current working backup and then older ones go in storage. I wouldn’t trust another brand at this point.

I had expected this to be much quieter – I realize it’s a mechanical drive, but I thought that the housing would block the sounds.

THIS MAKES # 12 EXTERNAL HARD DRIVE, ALL LACIE. NEVER HAVE I HAD ONE GO BAD.

Good performance, well-made, attractive design, no problems. I’ve used several of these LaCie D2 drives, and I’ve only had good experiences with them.

After 2 months of heavy use, no problems; transfer rates as advertised. I’ve found d2s are highly reliable.

I just started using this for photo backup.and I haven’t used it much yet. It runs very quietly. It was ready for my MAC right out of the box with no prior formatting. Seagate and Lacie have always worked well for me with no problems. I have a Lacie drive that is going on 12 years and it has never failed. I use drives as an archive and not daily use (10-150 times a year) and never had a hint of problems. I have had hubs fail but never a Lacie or Seagate drive failure. I fear data loss and every piece of data backed up on at least 2 drives some data on 3 drives.

AS TECHNOLOGY GROWS THE SPEED OF THE HARD DRIVE GETS FASTER. THE EXTERNAL HARD DRIVE YOU HAVE TODAY MAY BE WAY TO SLOW IN A FEW YEARS AND COMPATABILITY MY CHANGE SO YOU WILL HAVE TO TRANSFER YOUR DATA TO NEW EXTERNAL HARD DRIVE. MY OLDEST DRIVE STILL WORKS AS DO ALL MY LACIE DRIVES BUT THE TRANSFER TIME FROM THAT TB DRIVE TOOK HOURS TO TRANSFER BECAUSE THE TECHNOLOGY IS WAY FASTER TODAY BUT THE DRIVE IS RESTRICTED BY THE VERY OLD TECHNOLOGY THAT WAS USED WHEN I SAVED ALL THE PHOTOS WHEN IT WAS NEW. THIS DRIVE IS VERY FAST AND RUNS COOLER AND WITH LESS SOUND.

Plugged it to my mac and it worked problem free. Copy and write speed from computer to Lacie is as advertised. No issue with the product.

I have many LaCie hard drives. I like the older ones better because they have an on-off switch in the back. Not having the switch complicates juggling a number of hard drives.

Plugged it into my iMac and it just worked instantly. I wish that everything was that easy.

I tried all brands and no one beats this LaCie. Faster, silent and perfect to storage all files with safety

I’ve owned several d2’s in the past — all quality purchases. My early view of my new 14TB d2 Pro’s is they are large capacity; solid and fast performers; exceptionally quiet; warmer to the touch after extended read/write sessions — but not of concern; and without any other setting or intervention they automatically sleep and wakeup soon after my Mac does. In my opinion, you get what you pay for and these are worth every penny. The only downside is the blue status light is B-R-I-G-H-T enough to light a dark room at night and can be distracting if they are blinking while you’re trying to sleep even down the hall, or if you have them running perhaps in an office when people outside will think the Martians have invaded the place with the bright blue blink-blink-blink. I placed a piece of dimming film over the light and I still have a visual status what’s going on with the drive, but without the nighttime glare.

I’ve been using these LaCie drives for iMac backups and music sample libraries about three years now and have no complaints. They seem to be good bang for the buck, and I keep duplicate backups just in case.
