Comment Kind of obvious (Score 5, Interesting) 86

It makes sense, Apple's in-house processors have been a major competitive advantage, particularly at a time when Qualcomm has been leveraging patents to get a near-monopoly in the SoC space. Apple's chips have been a generation ahead of the competition for some time, although their infrequent release schedule mitigates that when everybody else catches up and then passes them before the next A chip is then released.

Using B&H pricing, a 3.3TB raw capacity ODA cartridge is US$188.57, while a 6TB raw capacity LTO7 tape is US$177.83.

So the ODA cartridge (which I think is Archival Disc instead of BDXL like the 1.5TB cart) is a little less than double the price per gig of LTO, but the upside is that the ODA cartridge should have a random access time of a fraction of a second while the LTO tape seek time would be maybe a minute.

And have a real world lifetime of a few years. Archiving data is a tough job. Storing it in an amorphous, heat and light sensitive material is data suicide.

That rather flies in the face of Sony's claim of 50+ year lifespans for current ODA cartridges. I understand that they're offering a 100 year warranty on the gen 2 cartridges that use AD.

I'm pretty sure that we're all LTO here though.

> In the 90s and 00s we'd get monthly articles about a new optical format that would store 1TB of data using holograms and fairy dust. None of them ever made it to market. Even now all we have is 100GB quad-layer Blu-rays.

They basically turned into the Archival Disc format, which has a first-generation capacity of 300GB per disc and a second generation capacity of 1TB per disc. The problem is that they keep delaying them: they were originally supposed to launch in 2015.

In the mean time, Sony went ahead and used BDXL for their Optical Disc Archive cartridge format, which stores up to 1.5TB per cartridge by sticking a bunch of BDXL discs into the cartridge. Those have been shipping for years. Once the 300GB discs are finally available, they're expected to use them to refresh their cartridges with capacities of 3.6 TB. They're meant to compete with tape. IIRC they cost a bit more but have much better random access times, and they're still much cheaper than hard disks.

It's a backlog that has only ever grown in spite of SpaceX launching up to 8 times per year, and would likely attract more interest from customers if they were launching regularly and didn't have a many-year manifest to work through. Even if they launched 25 times per year and only continued signing launch contracts at their current rate, they'd probably need at least four years to run out of things to launch. Their poor cadence is a problem that has already cost them business (due to the long wait time), and they could probably just reduce their cadence once they manage to reduce that backlog.

That also assumes that they're not able to increase their market share. They're working on reducing their prices to try to capture more commercial business, they're working on getting government/military contracts in the US, and they've already lost a bunch of business to the competition because of their poor launch cadence. I'm not sure if all of that would be enough to support 25 launches per year in the long term (beyond the time needed to clear out the current manifest), but they do need that sort of cadence in the near term to clear the backlog.

In the long term, if their own constellation ever happens, that's at least an extra 200 or so launches for the initial constellation, and then roughly 30 launches per year to maintain the constellation (due to the 5 to 7 year lifespan SpaceX has given). I'm still pretty skeptical about their constellation, though. I think the odds are that it won't happen.
