Pros
Cheapest serious capacity for a desktop
Cons
Seek noise carries if the case has no damping
Comment
Still the cheapest way I have found to add serious capacity to a desktop. Three years on, no errors, no noise beyond the usual, and it has never once been unplugged!

Pros
Passed a full surface scan first time
Cons
Packed far too lightly for a bare drive
Comment
Drive works, no faults, but I am marking it down for what arrived rather than what it does. It came in a plain padded envelope with a thin bubble wrap sleeve, which for a bare 7200rpm drive is not enough. It passed a full surface scan and has been fine for three weeks, so no harm done, but I spent the first evening waiting for the scan to finish rather than using it.

Pros
Holds a great deal for the money
Cons
Loud enough that I moved the machine to the floor
Comment
Does the job, holds a lot, spins loudly enough that I moved the machine off the desk and onto the floor.

Pros
Reads a media library all day without complaint
Cons
Buzzes into the case panel until you fiddle with the mounting
Comment
Perfectly good drive doing perfectly ordinary work, holding a media library that gets read far more than it gets written. My only real gripe is vibration. Mounted on the standard rubber grommets it transmits a noticeable buzz into the case panel at certain points in the spin, which took a bit of fiddling with the mounting to settle down. Once sorted, no complaints at all.

Pros
Two years of nightly backups without a single error
Comment
Eight terabytes was the right size for a single drive backup target, big enough to hold everything twice over without going into the price bracket where you start thinking about redundancy differently. Two years of nightly backups and the drive has not put a foot wrong. It is a 7200 drive so it is not silent, but in a case with any sound damping at all you would struggle to pick it out.
Poppy S. Used for: 6–12 months
Pros
Six terabytes of archive and nothing at all to report
Comment
This has become the drive I recommend when someone asks what to put in a machine that needs a lot of room and does not need it fast. Mine holds a photo and video archive going back about fifteen years, roughly six terabytes of it, and everything about working with that archive is unremarkable, which is the point. Browsing folders of thousands of raw files is instant because the operating system caches the thumbnails on the SSD. Opening a file off it takes a moment longer than off the SSD and that is the whole difference. Sustained read sits at 235MB/s at the outer edge, dropping to about 120 as it fills towards the inner tracks, which is normal for a drive of this size and worth planning for if you are timing a big job. Nine months in it has been completely uneventful. It runs at 40 degrees with one intake fan and it has never given me a reason to check on it twice.
Sophie W. Used for: 3–6 months
Pros
Cheaper than any external mirror I priced up
Cons
Formatting eight terabytes takes an age
Comment
Went in alongside an existing 4TB and the two now mirror each other, which was cheaper than any external solution I looked at. Formatting took a while, as you would expect at this capacity, and after that it has simply worked. Runs a little warmer than the older drive, about three degrees!
Harry R. Used for: More than a year
Comment
Bought to consolidate a drawer full of external drives into something that lives in the machine and gets backed up properly. That job is done and the drawer is empty. Transfers off the old externals ran at around 190MB/s which was limited by the USB enclosures rather than this drive. It has been powered on continuously ever since with no reallocated sectors and no attention paid to it at all
