It's awe inspiring to see fifteen terabytes of solid state storage in that little box.
What's more amazing is that it's still a long way to go compared to biological storage: https://news.ycombinator.com/item?id=4396931
Anyone care to take a guess how much the 15TB version will cost?

Does that density include the connectors and buses that would be required to access those cards?
Then you have to include the connectors and buses to access the SSD as well. And it will still be in favor of microsd, which can be read by a tiny connector + tiny controller in a smartphone.

It takes 8 hours 20 minutes to write 15TB over 500MBps. Why would you want to stick one of these in a RAID though? ..it would be more like Redundant Array of Prohibitively Expensive Drives. (I'll show myself out)
article says 1200MBps.. so more like 3.5 hours.
I happen to have a 950 Pro, and normal usage keeps the temperature at reasonable levels (though I stuck heatsinks on mine), but this is much more dense (512 vs 2 on the 950 Pro).

That sounds perfectly reasonable, and 20 years ago I'd have said the same thing. It's even fairly likely that I did say it. You know where this is going, right? I was a SysAdmin at the time and one of the things I was responsible for was Oracle Financials. It was at the core of everything that mattered at that company -- and I was absolutely convinced that short of a water balloon fight in the machine room, my raid c…
> The first disk died late on Friday. I had two on-hand so I casually replaced it -- and before I got back to my desk another had died. That happens very very very often. It has nothing to do with a bad batch. The second disk actually failed a while ago, but no one noticed because no one read from that part of it. When you did the rebuild you read from the failed area and woke up the failure. When you setup raid you…

10,000 USD?

I wonder, for such mission critical data a good strategy would be to start rotating out old drives at set periods. Maybe replace one drive of your RAID5 every 6 months, not matter what the health. Once you've replaced all the drives, they will all be staggered in age by 6 months. Hopefully then the chances of multiple failures is greatly reduced.
Impressive. First question that pops into mind is how long the rebuild time would take if one of these failed in a RAID. I can imagine it'll take a while.

I thought RAID and SSD were a terrible combination. As if both drives do exactly the same writes at the same time, chances are they will fail at the same time. Plus most RAID controllers don't support TRIM. Has the thinking changed?
> I thought RAID and SSD were a terrible combination Well there are different RAID settings. My product is an indexing engine (indexes Git repositories) and I've personally found RAID 0 reduces indexing time by about 30% compared to a single drive. I have a machine that has 4 SSDs running RAID 0 and I've found the performance gain after 3 SSDs is negligible. It seems like 3 SSDs running RAID 0 is the best combination…
