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?

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

      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?

        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.

          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.

            Ok, so does that also mean we can check the SMART parameters now?

            Previously, the USB interface effectively blocked access to them.

        the 2.5" size of disks are now mostly direct USB controller disks rather than sata adapters internally.

        3.5" disks are still SATA as far as i’ve seen but the actual sku’s of the disks are often the lower grades. like you will get a disk that looks like another good disk but with only 64mb of dram instead of 256 on the one you would buy as a bare internal drive for example so they can end up a bit slower. and warranties are usually void.

      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.
