Eggcellent product! 8/24/2020 2:28:56 AM

Pros: - Easy to install
- Easy to format
- Fast drive and good quality
- Arrived before estimated date

Cons: - None so far

Overall Review: I would definitely recommend this drive for any who need a larger one but can't fit the fat ones in their laptop! It so far has been a fantastic product and hopefully stays that way. I shall return later if there's anything new to share.

Small size big capacity. 8/23/2020 7:34:56 PM

Pros: Small 2.5"
Formatted 3.8TB
Runs fairly cool.

Cons: 15mm height. You can't put this in a laptop. Not a big deal for me.

Overall Review: Interesting: I ordered two of these, and one came formatted with some Segate easter eggs in it. Nothing interested me so I wiped it. The other one I ordered was unformatted. So I put a GBT initialization. GBT is the only way you can format these as one big partition. They come out as 3.63TB of useable space (nice). They run fairly cool. They are mechanical, but the large storage space makes up for it.

Update: I filled them up archiving data, and they do run very cool.

3tb Drive 8/19/2020 5:53:02 PM

Pros: Decent drive, decent price, sata 6. Short lifespan. I used this primarily for Non OS storage.

Cons: Died in less than 20000 power on hours since, owned Dec 2016. To contrast I have a WD Green 2 TB from 2012 that has 44000 hours on it and has had at least 5-8x times the amount of reads and writes with no issues. Failed just outside of warranty. What is weird is that I had no issues until I decided to upgrade to a 4tb to condense some the amount of drives in my pc. After data transfer it started failing. Not sure how long the sectors have been bad for but glad my data made it.

Overall Review: It's ok but a mainstream production drive should last at least 5 years in my opinion. This is the first Seagate drive I have owned, all others have been WD. Maybe my case was just bad luck, just wish it was still under warranty..

Disk arrived, and so far it's working fine. 8/19/2020 9:38:57 AM

Overall Review: This is the only drive I found on the recommended list for the UniFi Cloud Key 2+, so I ordered it in after the Cloud Key misbehaved in a way which has been correlated with flaky disk drives.

Did the trick!

Drive works. Need custom caddy for laptop internal use. 8/16/2020 6:45:30 AM

Pros: The drive works. No complaints, yet about that.

Cons: The measurements on paper say it should fit with the brackets. I read complaints about it being too big and not fitting. That is not my problem. There is plenty of space, but no brackets to secure it. The brackets on my current hard drive are too small. I need to find custom units.

If you are going to use this in a laptop. Make sure you have the caddy brackets. Standard detentions will not work for most of you.

Overall Review: The drive physically works. Nothing wrong there yet.

Unless you are going to use this drive in a desktop or have caddy brackets wide enough. Buy another drive.

If you want to use this drive to save space in your desktop. For cooling purposes. I say by it.

Big storage for laptop at price 8/6/2020 9:05:08 AM

Pros: Good dollar per terabyte
Slim enough for notebooks
Seagate is quality brand I trust

Cons: SMR recording
Good for low activity level bulk storage
Performance hit over CMR

Overall Review: Good for backup storage but should be avoided for demanding performance levels. Note that all laptop drives over 1TB are SMR I think.
