Seagate BarraCuda 4TB SATA Mobile Hard Drive (ST4000LM024)

Thanks to Scott for going above and beyond helping me to make the product in use and to not return it (coz i hate returned items). And now the item is working and running! We’re both problem solver not just “if its not working just return it” guy.

Thank you and appreciate all your effort for helping me!

Great product and customer service! I bought this drive to expand the storage of my Eufy Homebase3 for eufy floodlight e340 cameras. Just follow the instructions when you install it. Running smooth and lots of space.
Customer service is excellent, I texted them during the process and everytime, I got an inmediate answer. Very professional and helpful.
Buy it, you will not regret it.

I purchased the item to replace the hard drive on my ps4 since all the connections match my original ps4 model. Works perfectly but it’s a bit of a challenge to reconfigure my ps4. To replace my original drive I needed a usb drive with the update file, the 1 GB version not the smaller file. Once I got the right file, from Sony, the installation was no problem. If you are changing the drive you’ll need to backup your save files with psn or a usb drive. It’s also convenient to move your games off the hard drive to a usb drive then once your new drive is configured you can just plug in the drive and the drive will load the games to the new desktop.

My Unifi Cloud key Gen2 plus came with a 1TB hard drive. After five years of continuous use it was becoming slower and less predictable in connecting to the Unifi Portal.

As was somewhat apprehensive about using an SSD as they are more expensive and have a finite read/write capacity.

The problem with a larger capacity hard drive is that the 2.5 inch format is limiting. Ideally, one should choose a CMR drive for an NVR. However, the only CMR 2.5 inch drive is the 1TB Toshiba. If you want a larger drive, you end up with an SMR drive. That will decrease the longevity of the drive. As they say, mileage may vary….

If only Unifi allowed a 3.5 inch drive, but they don’t and there is no workaround other than MacGyvering an external interface.

This drive is fast, is essentially plug and play, and is working without a hitch.

Just remember to confirm there is a recent backup of the Unifi operating system or you will lose all the camera and other hardware connections.

In short: 300% failure rate within one year == garbage drives

Update 20180416:

Third replacement finally finished pattern testing. Over 2400 hours continuous activity writing patterns to the entire accessible space and reading them back, plus another couple hundred hours of continuous seek-then-read-and-compare operations. Like the others (except the second replacement) it passed all this without a hitch (though the original and first replacement only had to endure about 700 hours of this). The SMART values claim no sparing so far and that everything looks good, so it’s off to a shelf because Seagate says they refuse to support my non-Seagate enclosure. Let’s see whether I can read back the pattern I wrote to it in another couple months.

Update 20171127:

The second replacement is DOA — claims capacity over 140PB but can’t even access sector zero. Drive can not enable SMART due to errors, so can’t even see anything about the errors.

I don’t care anymore that they have improved customer service; with this level of reliability, even white glove replacement installation would be utterly meaningless.

Update 20171005:

The replacement drive is failing. Same symptom as the original — critical filesystem sectors that are not usually rewritten are returning uncorrectable ECC errors, and other evidence of bit rot. Either the replacement drive hid it better or it just took longer; not sure. On the positive side, the time between failures is better than many Seagate drives I have tried, but it’s still far too short (needs to be more than five years, not merely more than five months).

A Hitachi Travelstar 7200RPM 1TB drive placed in an identical installation at the same time and subjected to the same use and handling as the original Seagate 2TB and then the replacement is still working well, having outlasted two of this Seagate model.

Update 20170908:

The replacement drive looks good so far and no apparent evidence of bit rot. Maybe this means Seagate drives are becoming less prone to suffering bit rot. I raised it to three stars because it seems better, but only three stars because of my long history with Seagate makes me worry a little. Still, it shows some promise and so I might try another drive from Seagate just to see whether this was luck or a trend.

Update 20170331:

Seagate allowed me to do an advance exchange on the drive; I have the new one and they have the old one now. Hopefully the new one holds data longer — I will update the review once I am more sure of that (at least a couple months). I gave back a star because I didn’t have to fight with them to get the return accepted this time; if something happens there, or if the drive looks good in a couple months, I will update this again.

Original review:

I wanted a >1TB drive in 2.5″ 9.5mm height or smaller. Pity nobody else makes one.

Like (almost) every other Seagate drive I have purchased in the last 20+ years, this drive suffers bit rot. Write data to it, read it back, it’s good. Leave it alone for a month and it can’t read some of it (uncorrectable ECC errors). Wipe it, verify all sectors good, write data to it. Leave the data in place for a while (even powered off sitting on a shelf), come back to it. Unable to read everything due to uncorrectable ECC errors.

I’m going to try to get this one replaced in hopes it can be done, but every other time I have, tried Seagate insisted that I use their tools to replace the bad sectors and then it verified good. Sit it aside for a while and even zeroed sectors rot; try their tool and it rewrites all the bad sectors, then declares the drive fine again. They historically will not accept return of a drive that will not ‘stay’ bad after having all its bad sectors rewritten.

I’ll update this if Seagate accepts the return of this drive and the new one isn’t also junk.
