For sure, there could be one person with 1.1 and 10 people with 0.99, but the average will still be 1.0

“Half our students are below average!” kinda vibes - KDR necessarily means that for every person with 1.5, there is someone with a 0.67, that’s just how the math works. If I’m anywhere near 1.0, I’m happy.

Absolutely, it’s a fabulous engineering challenge, to make it work well on a hobbyist grade 3D printer with ordinary materials. Also a lesson in using the right tool for the right job (some parts are just better off milled or bought OtS)

I used to frequent the FOSSCAD IRC ages back as a teen. This started during the post-Liberator panic, there were talks about regulating 3D printers to not allow printing guns, etc. Designed a few things, never actually printed any of it myself, but some others did. Really got me into engineering before I exited the scene, led to actually pursuing an engineering career. Was surprised to see 3D printed gun videos so openly shared, it was pretty underground for ages there.

Yeah, no data loss, rebuilt within 48 hours each time. 10TB is a nice balance that doesn’t have such long rebuild times

The first two died within 30 days, the second one took about 4 months I think. Not a huge sample size, but it kind of matches the typical hard drive failure bathtub curve.

I just double checked, and mine were actually from a similar seller on Amazon - they all seem to be from the same supplier though - the warranty card and packaging are identical. So ymmv?

Warranty was easy, I emailed the email address included in the warranty slip, gave details on order number + drive serial number, and they sent me a mailing slip within 1 business day. Print that out, put the drive back in the box it shipped with (I always save these), tape it up and drop it off for shipping. In my case, it was a refund of the purchase pretty much as soon as it was delivered to the seller.

I currently have 6x10TB of these drives running in a gluster array. I’ve had to return 2 so far, with a 3rd waiting to send in for warranty also (click of death for all three). That’s a higher failure rate than I’d like, but the process has been painless outside of the inconvenience of sending it in. All my media is replaceable, but I have redundancy and haven’t lost data (yet).

Supporting hardware costs and power costs depending, you may find larger drive sizes to be a better investment in the long term. Namely, if you plan on seeing the drives through to their 5 year warranty, 18TB drives are pretty good value.

For my hardware and power costs, this is the breakdown for cumulative $/TB (y axis) over years of service (x axis):
