This is a sort of followup to a message[^] from Paul (@OriginalGriff) about 7 months ago. He'd posted that he'd bought some 4Tb drives from Amazon at a cheap price, supposedly refurbished, but they arrived 'as new' with warranty cards.
I'm wondering what his experience has been with them so far and how it matches with mine. I'd also be interested if anyone else bought some and what they've found.
In my case, I've previously been using Seagate IronWolf 4Tb drives (model ST4000VN008) in a 6 disk ZFS array (Raidz2, i.e. 2 out of the 6 are effectively parity). The disks were all around 33000 power on hours and one had "failed" according to the SMART data. So I initially bought 2 of these drives, which turn out to be HGST Ultrastar 7K4000 drives. I replaced 2 of the Seagates, bought 2 more HGST drives, replaced 2 more Seagates, bought a final 2 and complete the rebuild of the array.
Then 1 of the HGST drives reported failure. So I sent it back to Amazon for a refund and bought 2 more, intending to keep 1 and a spare. Shortly after that, another failed, so I sent that back for a refund and used up my spare.
Just recently, another drive has reported failure. I enquired via email about the warranty and was told that the company whose name is on the warranty card only sell the the US, so my drive isn't covered as it's a resale. So sent it back to Amazon for a refund and ordered an identical replacement, only now it's double the price.
This one had a manufacturing date on it of October 2016! So I've done a bit of searching and, as far as I can work out, these drives must have been manufactured between 2012 and 2019, but I can't find a way to work out exactly when. HGST was acquired by Western Digital in 2012, but they continued to make HGST drives for a few years.
So these are actually New Old Disks (Old New Disks?) and have presumably been sitting around unused for years - hopefully in reasonable conditions for storage!
I'm beginning to think this may have been false economy and I'd have done better sticking with newer Seagate drives despite the price!

Black holes generating enormous power has been around in science fiction for a while (Arthur C. Clark - Imperial Earth (1976)). More recent in the Star Trek Universe with the Romulan D'deridex-class warbird uses an artificial quantum singularity as a power source for its warp propulsion drive.
from the Wikipedia article ( Black hole starship - Wikipedia[^])
" A black hole weighing 606,000 metric tons (6.06 × 108 kg) would have a Schwarzschild radius of 0.9 attometers (0.9 × 10–18 m, or 9 × 10–19 m), a power output of 160 petawatts (160 × 1015 W, or 1.6 × 1017 W), and a 3.5-year lifespan"
That's a lot of power from a tiny space.

When visiting a friend last weekend, I mentioned as a side remark that lots of people never gave a thought to the name 'Edge' - similar to the old days when lots of people using the Lynx browser never associated it with anything but a big, wild cat. My friend knows a lot of math, including a fair amount of graph theory. Yet, he gave me a puzzled look: What do you mean? Is that name supposed to mean anything special?
Well ... Yes. Like Lynx. And the little Ford Ka (that's some years ago, isn't it?). And the arrow below the Amazon text in the logo. One common brand of Californian raisins imported to Norway had the brand name 'Sun Maid' (with a picture of a young woman carrying a basket of grapes) - my mother never ever would accept the idea that 'Sun Maid' was a play of 'Sun made', ripened in the sun. Marketing folks come up with lots of bright ideas in this class, and 99% of the audience ignores/overlooks it. I am sure that they are prepared for that  .
I guess that a fair share of the Lounge audience has had their share of graph theory. So let me ask: Have you ever been considering the name 'Edge' as related to hypertext graphs? Or are you considering it to be just a random name picked out of the blue?
(If you care to indicated whether you feel familiar with graph theory, that would be an interesting additional piece of information!)

In my part of the world*, a dissected plateau, there are many clifftop lookouts and walking trails.
There is a lot of signage encouraging people to keep away from the edge, which I consider excellent advice.
* The coincidence between my postcode and an ancient IBM RJE device/protocol I find amusing.
