I shoot a lot of pictures and my camera is a 100 MP camera so the files are quite large, when I go out I will fill a 256 GB card with ease. so the need to a large Hard Drive is something I need maybe not you, but I filled a 10 TB drive up in the last 7 months. It is fast enough for my needs and formats with ease for a Mac. just purchased a 28 TB for backup because it was on sale and the cost was only $10 more. I am old enough to remember the first hard drives 20 MB would cost you $200 back then and computer memory was 128 K for a big one my first was 16 K. boy how times have changed.

This is a GREAT drive for storage. It does, however, have absolutely abysmal read/write speeds and thus transferring data will take a while, even if it's just 1 GB of data. 2TB is plenty of space to backup old computer files, as well as transferring data between computers. I have had this drive for about a year now and it's held up alright. It's super small and slim so it doesn't take up much space. It actually fits comfortably on top of my computer tower with room for other stuff. My main gripe is that upon adding this item to my cart, I believed it would be good for extra storage for video editing. And technically, it is. You just can't actually EDIT on this drive. Trying to edit on this drive makes the editing software load files extremely slow. The way I wound up using it was temporarily storing files until I needed them back on my main internal drive. I have since upgraded my internal SSD to resolve this issue entirely, but it's just something to keep in mind when you buy this.

I’ve only had it for a few days but it works. I have noticed that if my Adobe Premiere files are on this drive then it can take about a minute to get going if you take a break from editing for long enough for the disk to stop spinning. I wouldn’t plan to use this if you’re recording sound because it can be pretty loud. It is nice to have 18TB (20TB) all in one drive. I use it as a backup for all of my smaller drives that I take to work and on shoots.

Excellent product, have used it several times and has worked wonderfully. Had an issue with install, contacted customer support and they were great to work with, and had me up and running in no time at all. This is the second Seagate back-up hard drive that I have owned, I replaced the older one with a newer larger capacity. I have had zero issues and no data failures with their products.

I use 16 such drives, a mix of Seagates and competitive drives, for my backup solution (two sets of backups of two machines, each of which requires four drives -- I have quite a bit of data -- with one volume set stored offsite at all times). This kind of drive is certainly the most cost-effective solution for 5 TB of bus-powered storage, but it has some limitations. Unfortunately, 4 TB SSDs are still prohibitively expensive for this application, costing about 4x per byte more. 1) It's a shingled magnetic recording (SMR) drive. That may be needed to achieve this kind of storage density on platters this small, but it does mean that if you're trying to write multiple terabytes of data to this drive, it will typically slow down drastically after the first 100 GB or so. That may well depend upon the filesystem used on the disk. I'm using ext4fs in a LUKS-encrypted container on Linux; writing 4.5 TB of average 10 MB files took me well over a day. Write throughput frequently dropped under 10 MB/sec for extended period of times, interspersed with short periods of 70-100 MB/sec and averaging about 25 MB/sec. The same applies to drives made by competing manufacturers. This is much less of a problem with incremental backups, which are much smaller and which the drive can handle within CMR cache. 2) If I create an encrypted LUKS container spanning the entire drive, I've found that I get I/O errors when creating the filesystem (mkfs.ext4) or checking the filesystem (with fsck). This does not happen with ordinary filesystem operations. Via a long story related to a single drive that had genuinely gone bad, it led me to believe that all of the Seagate drives in my fleet were bad. There turned out to be a simple enough solution to this: rather than using the entire disk, creating a partition starting 1 MB in. Once I figured that out, I had no further difficulty. This was not an issue with drives made by another vendor. It's not something most people will run into at all (if you use the drive as partitioned from the factory, you'll be fine), and losing 1 MB out of 5 TB is not significant. I suspect it's likely a firmware problem/limitation of some kind interacting with the LUKS container (it did not happen if I did not LUKS-format the drive). It's not a reason not to use this drive, just something to be aware of if you want to use these drives for cheap encrypted backups under Linux. 3) When writing large amounts of data to SMR drives, it's first written to CMR (conventional) cache space on the drive, which is fast (100-140 MB/sec). After writing is complete, the drive will spend some time reorganizing the data on the drive. As such, it is probably a good idea to leave the drive plugged in for some time after writing a large amount of data (I usually leave it for 30 minutes after writing an initial backup to one of these disks).

So far so good! It has been a month or so and I have copied about 15TB of data to this drive already. It is responsive and very quiet. It is set as a backup for my UGreen NAS. Basically a backup for my backup!

On a Mac, DO NOT format it as the default choice: APFS. After it stopped responding, I later realized APFS is only for SSDs. Unfortunately I didn't find this out until I returned it to Seagate under warranty (sorry seagate). Seagate warranty replacement was great though!

I loaded years of pictures, files, and info from our two old computers in this, and still have space! Easy to use and great way to store back up of a back up! Secure log in and password can be set which is another great function. Small but mighty!
