These things (and Seagate's) have the usb interface soldered on, so if the drivd dies, forget about the data, no way to connect to another usb adapter to try to recover. Granted, it's usually the drive that dies, but in these cases, you have a 100% rate of non recovery . Any other brand's are standard drives. My favorite are toshiba.

Why would the USB electronics be particularly likely to fail relative to other electronics on the drive?

[–] [email protected] 29 points 6 months ago

Because you flex and replug the interface often.

The thing you use to plug your phone, tablet, drives and other things with is very often the failure point unless you break screens or get water in them.

Normally you simply have a HDD drive with a SATA interface in there, so if the USB connector fails, you can still easily recover your data.

With these things, you're lucky if they even offer the possibility of repairing or recovering the drive.

[–] [email protected] 14 points 6 months ago

In my experience the drive fails more often than the adapter, but they do fail. Also, there is a good chance to recover data from a failed drive. With a soldered adaptor it's basically impossible. The worst part is that the externals are often used for backups.

[–] [email protected] 7 points 6 months ago

Because that's usually the cheapest part that manufacturers can get away with cheapening iut further.

Solder joints

Not particularly, but it happens.

I solder new usb connectors and all manner of other connectors on to stuff all the time.

I’m at a 100% success rate getting data off stuff that just needs new connectors.

If you need data recovered, the literal best case scenario is that it’s just got a bad connector.

[–] [email protected] 1 points 6 months ago (1 children)

Soldering is not the problem, unless its smd or tiny, its getting a non standard usb interface.

[–] [email protected] 0 points 6 months ago

you mean in the case of a dead USB ic or something or do you mean the USB port isnt standard?

[–] [email protected] 45 points 6 months ago (2 children)

Just don't look at the failure rates

[–] [email protected] 23 points 6 months ago (1 children)

OMG is it bad. We used a couple WD drives for a surveillance camera array and they didn’t last a year. Two drives failed 9 months apart. Ended up going on Blackblaze and picking what looked best for our XFS Raid 10 having learned that lesson the hard way.

Backblaze publish drive fail report

[–] [email protected] 1 points 6 months ago* (last edited 6 months ago)

Yeah our company learned the hard way when they bought out G-DRIVE. Got a line failure on 4x 20TB drives.

Switched back to LaCie and Glyph.

I have a dual NVMe USB3 caddy that's smaller than most 2.5 HDD housings with currently 2 2TB drives, you can buy 4 and 8TB nvme drives these days too. I can throw that thing out a car and it won't care.

And the drives are easily swappable and so are the electronics in the casing.

So no, 2.5" HDD's still are an utterly dead end of technology.

Especially with these and some other vendors, the USB interface is part of the drive (there's no SATA port on them), so you can't swap them or take them out for data recovery. They are HDD tech, which doesn't do shocks or any other sort of roughhousing, they are slow as shit and use far more power than any NVMe drive.

[–] [email protected] 9 points 6 months ago (1 children)

Which NVMe USB3 caddy are you using? I'd like to get me one.

[–] [email protected] 3 points 6 months ago

Looks like this one except that it is sealed on one end and the caddies for the two drives have a cover plate that screws in over a gasket and rubber ring.

I got it in a shop in Hong Kong when I was there for a convention earlier this year. No idea if you can find it online, maybe somewhere like Alibaba.

From the article:

UPDATE 5/17, 6 PM: Western Digital has confirmed that the new 2.5-inch T GB HDDs uses 6 SMR platters

SMR = shingled magnetic recording https://en.m.wikipedia.org/wiki/Shingled_magnetic_recording - "continuous writing of large amount of data is noticeably slower than with CMR drives"

Bought some of the old versions for backup drives. That was a mistake.

[–] [email protected] 9 points 6 months ago (2 children)

why?

[–] [email protected] 10 points 6 months ago (2 children)

Very high failure rate. even sony 2.5's have a similar rate of death. For some reason this form factor is just terrible for longevity

[–] [email protected] 2 points 6 months ago (1 children)

My bet is on density. You cram so much in such a tiny space, so any tiny imperfection or fault will corrupt the data or render the drive unusable.

[–] [email protected] 2 points 6 months ago

At the time it was fine. I had an array of 4tb drives that I was backing up with a series of 5gb drives. They were just so unreliable; all but one failed while the array they backed up is still spinning strong.

[–] [email protected] 2 points 6 months ago

Bingo. Sorry, had typed a reply about my failure rate and difficulties getting an RMA but forgot to submit.

[–] [email protected] 2 points 6 months ago

Not exactly reliable and less than easy rma process.

Sorry, had typed this and forgotten to hit submit :(

[–] [email protected] 6 points 6 months ago

I paid around $300 for one of the first 2TB drives. Surprisingly it hasn't come that far

[–] [email protected] 5 points 6 months ago

I've got the 5TB version of this drive as a backup for my gaming laptop. Haven't had any problems with it.
