Review: As Advertised - This is my 2nd LaCie 8TB drive. If you don't need SSD speeds, these are great drives. I would recommend. They are considerably faster than my 5400rpm drives. The difference is there! PROS: Read and Write speeds are as advertised. About 230-240MB/s on my 24" iMac. LaCie 5yr warranty is useful. I already had to call once and was surprised that an actual person answered and helped me. Just be sure to register it. Sleek design. CONS: The blue light on the front is bright enough to second as a lighthouse light. The drives are not quiet. You will hear them in the room, so beware if you record audio in the same room. Sleep mode is odd. I feel like they spin up randomly at night, which is annoying.
Review: The Cooling Fan - The fan on my LaCie 1big Dock Thunderbolt 3 4TB HDD and Desktop Hub was not turning on and the top of the case seemed to be getting quite hot after one hour. I decided to return it for a replacement so I did a secure erase. The drive was left on for several hours during this process and after time, the fan eventually turned on. I missed it in the manual (page 22) but the fan is temperature controlled so It will not turn on when you first apply power. The unit needs to be on for a L_O_N_G_ time to generate heat before you will notice any fan activity. I cancelled my return and am quite happy with it. This is a very heavy and well built external HDD and has been working well with TimeMachine for Mac.

### ⭐ Another crappy Seagate product- LaCie is just a name now....
*by B***S on December 28, 2019*

I used to buy Lacie drives all the time, and had no problems with them until Seagate's crappy quality and crappy customer service completely began to change the company. I had a pair of Lacie drives die on me and because Seagate claimed I had damaged the drive while traveling they refused to honor the warranty. That was a few years back. Fast forward to this year when I thought hmmm, I'll try them again. I bought one of these little guys for a project and since July it's been ok, while not nearly as fast as it claimed it would be. Meh. I wasn't too worried. Then 6 months later in December the stupid thing takes a nosedive and refused to mount. I took it into the Apple Store and they recommended I replace it immediately as the drive was corrupted and would probably not mount again. I called SEAGATE, and was told that I have to send the old drive in or they will not replace it. Because the blue light is still flashing on it they claim they have to assess it and if they determine it's defective, THEY keep the drive and send you a new one which may or may not be a REFURBISHED PRODUCT. The person I talked to could not describe any kind of standard for data security or privacy measures. This person told me that what they do is test the drives, if it works, they determine you lied and sent in a product that was fine, and you may or may not get it back. The BUYER has to pay for shipping. And again, through the whole process, there is no guarantee of privacy or protected data. They actually told me two different versions of how the product is tested for defects. Here's the thing. This isn't a pair of shoes. I have a lot of very sensitive client data on this hard drive and am loathe to just mail it off to a service center where who knows what will happen to it. The SEAGATE person was rude because 1) I would not provide all of my personal data to them, and 2) I asked if a replacement was possible without mailing in the drive that died. They got downright snippy with me when I asked how my privacy would be protected while they tested the drive. Avoid this company like the plague. LaCie is no longer the standard for nice external hard drives that worked well and looked good on your desk. I remember good customer service, a solid warranty and a good product. If the bad track record, poor customer service, and refusal to take responsibility for a failed product wasn't enough to avoid this company, here are some other problems I have: This drive has a GIANT BRIGHT blue light that constantly pulses and I had to put a little strip of electrical tape over the light because it was so distracting while in use. The old Lacie drives had a bright blue light that was kinda cool--- but not this giant garish flashing blue dot that would do better on a Las Vegas light marquee or in a truck stop bathroom. You know in some public spaces they put out those bright blue lights to deter drug users? Yeah it's THAT BRIGHT AND OBNOXIOUS. The drive is NOISY. Even when it's not in active use it's noisy. Don't make the same mistake I did. Avoid them.
