Hiya, so am looking to buy more storage and while browsing am seeing some external harddisks, such as Western Digital My Book and Seagate Expansion Desktop for cheaper than the internal harddisks themselves. Have seen this one video from KTZ Systems where he bought up multiple of these external ones just to open them up and use the disks for his own server. Was therefore wondering if you peeps have ever done this and if there any downsides to it at all?

Yup. And if you want to look up more info on how to do it correctly, look up hard drive shucking.

[-] Sunny@slrpnk.net 5 points 5 months ago
[-] Bizarroland@kbin.social 53 points 5 months ago

It's called shucking and it happens a lot especially in the home server home lab community.

It’s a bummer that hard drives are priced this way. It’s been common for a few decades now.

[-] lambda@programming.dev 4 points 5 months ago

The best ones for this are the ones from Best Buy. Easystore.

[-] xavier666@lemm.ee 3 points 5 months ago

Don't you think it's wild that a hard drive, which is just chilling inside its case, suddenly has its innards spilled out using a screwdriver, and dumped into a 24/7 NAS with other hard disks.

A bit inhumane if you ask me.

Yes I’ve done it. What sucks is you make a lot of trash this way. Also double and triple check that the drives you buy will have standard sata connectors on them.

[-] bjoern_tantau@swg-empire.de 10 points 5 months ago

I like the trash to hook up any hard drive via USB.

[-] JustARegularNerd@lemmy.world 5 points 5 months ago

Yeah one of these is literally my primary USB 3.0 to SATA adapter

Be aware. Some external USB drives, like WD Elements, have built-in USB controllers. So they don't have a SATA connector.

[-] Cyber@feddit.uk 11 points 5 months ago

This must've changed as I've shucked WD Elements / Book drives and they were normal drives...

So, you're saying the actual harddrive has a USB chipset onboard and only a USB interface?

When did this start happening?

[-] norbert@kbin.social 9 points 5 months ago

I've shucked probably 100s of those WD essentials and they just had a little SATA -> USB adapter on it. It's been a few years but it doesn't seem like they'd make a whole new PCB just to include USB.

[-] Dhs92@programming.dev 6 points 5 months ago

Within the past 2-3 years drive manufacturers have been swapping to USB PCBs directly attached to the drive controller, instead of using a SATA -> USB interface.

I think this depends on whether it's a 3.5 or 2.5 inch drive inside. To my knowledge, all external drives with a 3.5 inch drive inside are shuckable and have a standard SATA interface. With the compact drives that have a 2.5 inch drive inside, many will have a native usb interface and no SATA connector.

It makes sense as 3.5" sata drives are used for many many applications so why make something new just for external drives? With 2.5, however there are very few devices that use spinning sata drives in this form factor. It makes a lot more sense to build the USB interface directly on the drive since their main and possibly only application is external drives.

I could be wrong, but this has been my experience.

[-] Sunny@slrpnk.net 4 points 5 months ago

Good to know! thanks

[-] Moonrise2473@feddit.it 27 points 5 months ago

Yes and i got "scammed" - western digital in order to save $3 included the USB port directly on the drive motherboard instead of the usual sata+usb like anyone else was doing

[-] BeatTakeshi@lemmy.world 5 points 5 months ago

Same happened to me on a WD black

Yes. Be aware there will be some pin blocking you need to do to make it work right because vendors know this trick.

[-] stevestevesteve@lemmy.world 14 points 5 months ago

I have done this with dozens of drives and have never had to do any pin blocking. You only need to do that if you're using an absolutely ancient sata power cable that doesn't know about the spinup pin change

Yeah typical :P

[-] entropicdrift@lemmy.sdf.org 18 points 5 months ago

IMO, if you want the beast deals right now on a 12+ TB HDD, you should use serverpartdeals.com instead. I've got 2 manufacturer recertified 14 TB enterprise-grade drives from them and it was way cheaper than buying any 14 TB external drive.

[-] Sunny@slrpnk.net 8 points 5 months ago

Im based in scandinavia so wont be able to buy from there, but thanks anyway!

[-] rmuk@feddit.uk 7 points 5 months ago

Hey. Heyhey. Heyheyhey. Have you ever noticed that your warships have giant barcodes on them? It's so that when they return to port they can scan the navy in.

Yes. It’s a viable way to save money if you use a site like https://shucks.top/

[-] TheHolm@aussie.zone 10 points 5 months ago

Why create yourself a headache and still get substandard and no-warranty drive. If you want cheaper drives go for reconditioned/refurbished/used drives. Same risks, better product. Old enterprise SAS drives are cheap and many still have plenty of heath in them.

[-] qaz@lemmy.world 3 points 5 months ago

Do keep in mind that you need a SAS controller for that, which can cost between $50-200

[-] Ptsf@lemmy.world 9 points 5 months ago* (last edited 5 months ago)

Yeah! The practice is called drive shucking (kinda like Oysters) and you just need to be considerate of the limitations. The drives often end up cheaper, but lose warranty support once they're shucked. They'll also occasionally be slower than a normal drive or have an odd connector, but that is rare since it's usually cheaper to go with something 'off the shelf'. If you Google it though you should usually be able to find the handful of drive SKUs they'll use in whatever external you're planning to shuck.

[-] laughterlaughter@lemmy.world 3 points 5 months ago* (last edited 5 months ago)

oysters?

I have opened other enclosures and found a custom board on the hard disk.

[-] ares35@kbin.social 8 points 5 months ago* (last edited 5 months ago)

i bought a big external hdd recently on impulse... a clearance sale. it was really, really cheap. with the thinking that i could 'shuck' it because i'm short on space in a couple storage systems. i checked. i can, but i haven't. hell, i haven't even used it yet other than to run a full smart diag on it, followed by a full format and a read/write verify. took days. then i put it back in the box and have basically forgotten about it until now.

you have to be careful on what models you buy. some have usb built onto the controller board (no internal sata) or other things (e.g. encryption chip, weird power) that make it more difficult or even impossible to use the internal drive in an environment other than the enclosure it ships in.

[-] ikidd@lemmy.world 7 points 5 months ago

Shucked drives are usually the drives that are rejected for internal use because of quality issues. They might work fine, they might not. Be careful with them and remember, RAID is not a backup.

[-] infinitevalence@discuss.online 5 points 5 months ago

many times, shucking is a very valid way to get large format disks for cheaper than retail NAS parts. But be aware of what your buying and make sure that the disk your getting if its a white label is a reliable disk. WD Easystore/Mybook are generally good, as are the larger format Seagate external.

[-] lazylion_ca@lemmy.ca 4 points 5 months ago

This is what I did when I had to refurb a laptop. Swap the drives, reinstall the OS, snd hand it all to the user. All your files are on this usb drive.

Thats when you find out who understands folder structure and who doesn't.

[-] Phoonzang@lemmy.world 5 points 5 months ago

I guess it shows how out of touch (old) I am that it's completely bewildering to me that there could be people who do not understand folders ... on a computer. Phones, tablets, yeah, I get that, those actively make it harder and harder to access the folder structure. But computers?

[-] hperrin@lemmy.world 3 points 5 months ago

I haven’t bought them specifically for that, but I have harvested drives from them. A lot of times, you’ll have to destroy the enclosure to get to the drive. If you’re ok with that, go for it.

[-] Faceman2K23@discuss.tchncs.de 3 points 5 months ago

Used to be my main source of disks, but these days there are better ways and it is easier to know exactly what you are getting.

You might want to look up SMR vs CMR, and why it matters for NASes. The gist is that cheaper drives are SMR, which work fine mostly, but can time out during certain operations, like a ZFS rebuild after a drive failure.

Sorry don't remember the details, just the conclusion that's it's safer to stay away from SMR for any kind of software RAID

EDIT: also, there was the SMR scandal a few years ago where WD quietly changed their bigger volume WD Red ("NAS") drives to SMR without mentioning it anywhere in the speccs. Obviously a lot of people were not happy to find that their "NAS" branded hard drives were made with a technology that was not suitable for NAS workload. From memory i think it was discovered when someone investigated why their ZFS rebuild kept failing on their new drive.

[-] ares35@kbin.social 3 points 5 months ago* (last edited 5 months ago)

i bought a few smr drives, knowing they were smr. they were cheaper, a lot cheaper than the same amount of space in cmr. used only for static media storage, so that's not a big deal, really., but holy hell was it slow getting stuff on them initially.

i have a few self-powered externals that are also smr (quite common with those as they use 2.5in notebook hdd). when those things have to start shuffling bits around and rewriting tracks, sustained write speeds fall well under what even usb2 can send.

Not specifically, no. When I did change to building my own NAS, I cracked open my older 4TB backup drive to use as a spare.
