LaCie (LAC9000633) Rugged Mini 4TB External Hard Drive Portable HDD – USB 3.0 USB 2.0 Compatible, Drop Shock Dust Rain Resistant Shuttle Drive, For Mac And PC Computer Desktop and Laptop, Orange

Right from the box to my Mac for Time Machine back up. Completed in less than two minutes

This hard drive works amazing for storing all the photos and videos from your phone or computer. It is easy to setup and store. The speed to load and transfer files is quick. Worth the money for all it can hold. It doesn't overheat if using it for some time.

GREAT DANE PROOF! these hard drives may be the toughest hard drives around. if you have kids or dogs like me I highly recommend them. I came home one day to my Great Dane puppy throwing one of these up in the air in my back yard and and trying to catch it. he had pulled the cord out and chewed entirely around the sides of it. all while doing this in the dirt pit in the middle of my yard.( my fault I left the hard drive on a table next to my couch.) well fast forward to a year and a half later and I still am able to use this hard drive as normal. I recommend them all day. transfer speeds are good. rubber case is durable. and no issues with compatibility for my Mac.

This nice little drive is big in storage. I use it for Time Machine backups as the drive is seamlessly Mac compatible, and I'm very happy. Couldn't be easier to set up on Mac. Data transfer over USB3 is fast for my purposes — and that's how the drive is powered! Gone are the days when you needed an external power source — one usb3 cable serves for power source and data transfer. I understand that spinning hard drives (HDD) like this drive are better for data integrity than Solid State Drives (SSD): since my mac's drive is solid state, it makes sense to back up onto a spinning HDD — and it's much more affordable than a comparable SSD. I travel a lot, and I've been burned in the past by HDD failures due to drops, bumps, etc., but LaCie boasts protection against shock, drops up of to 4 feet, and dust and water resistance. We shall see... I'll update this review if I have any trouble.

REVISED 01/01/25: I purchased this to back up a half-full 6TB Seagate Backup Plus drive that's acting flaky, attached to my MacMini. UPDATE: The drive came formatted EX-FAT (Mac and Windows compatible) with a USB-C to USB3-Micro B "Super Speed" (two lobes, for the drive) cable. With no spare USB-C ports on my MacMini, I used a Samsung USB3-A to USB3-Micro B cable from an older Seagate drive into a Sabrent USB3-A hub on the MacMini. It worked fine at first, then failed as described below. Retrying with the LaCie cable into a USB-C to USB3-A adapter into the hub worked. Super sensitivity in the Mac system? I have no other explanation as the drive continues to work on Windows PCs with the old Samsung cable. INITIAL REPORT: It mounted fine out of the box, and macOS Disk Utility recognized it as a 5TB volume "LaCie." The first few copy batches of multi-GB files and folders worked OK, but then copying stopped, and macOS Sequoia 15.2 reported "Copy operation stopped, volume disappeared." (WTF??). macOS Disk Utility no longer sees the device. It mounted as a USB volume on Windows 11, and I could see the copied files. Windows reported disk problems so I ran the Scan & Repair utility (Properties->Tools), which took a while but reported a successful repair. Trying again on macOS, and the same result: The drive starts up (vibrates) as expected but doesn't mount and is still invisible to the Disk Utility app.

The LaCie Rugged 5TB Portable HDD delivers precisely what it promises: ample storage in a rugged, travel-ready shell.

I regret that my two year experience with this drive using Mac machines is not positive. I have not found it to be reliable. To recover files on the drive now...again...I must fire up an antique Chromebook, which sees my files so I can back them up elsewhere. It worries me and I'm not messing with this drive further. -- Same issues on newer UnionSine drive. Drives mount one time but not the next...Disk Utility hangs trying to find it...workaround is to mount the drive on my ancient Chromebook...which sees the drives and files fine...then retry on Mac...usually this works but it is really weird...I see now it has to do with how I formatted these drives as exFAT as advised...both my Macs randomly spit it out and say yuck...nerve wracking as these are important back up drives...honestly WTH why are we still having drive compatibility crap like this? So apologies LaCie it does not seem to be your fault...

This 4 TB hard drive works perfectly well for me. I've got 4 Lacie Rugged drives now. Two 1tb, one 2 tb and this one and they all work perfectly. I've had the other three for several years.
