Sony Developing 300GB Blu-Ray Successor

[Boris Goodenough]

and relaiability. and longevity. and price. SSD is a great drive on paper. in reality however so far it is a total failure.

Depends on the market segment, I know that servers with SSDs (NAND) have not had the same failure rate as consumer oriented ones and have had fewer compatibility problems.

Longevity has only been a problem on paper so far, people with consumer SSDs (Samsunb 830 256 GB) have been writing to them at 25 GB/day for months without any sign of degradation (from HardOCP, currently unable to find the link). The failure rate that is given on their respective NAND flash say so and so many 1000 writes before they fail, that is worst case scenario and only at a 3% failure rate per given amount of writes.
Anand(tech) has also addressed the failure rate issue, they haven't found any problems either (outside of firmware problems), unless you will use TLC NAND for business/calculation servers where SLC is intended.

USB sticks? yeah, that may work as a plan B if discs were to somehow dissapear. Cards? they are already only fit for mobile devices, and even then its much better when they use their own HDDs. heck, mobile devices always were the extremely late adopter when it comes to storage space anyway. "you got 10 mb. what is this you want more? nope we dont make such models.". well at least now it begins to get 2-4gb internal storages. Disc is very durable when it comes to longevity. As for speed neither USB nor cards can compare. maybe USB3 could.

That's why I said "move away from disc technology". We should work on developing new, more efficient ways to store data.

But discs are the most efficient way to store data that we know. sure, invent new one if you will, but dont attack the most efficient one before you done that.

Except that SSDs so far seems to have a realistic lifespan of around 1-2 years. also 25gb/day is small. for example yesterday my HDD went though around 90 GB traffic. Though granted majority of that was read. 1000 writes is a very small number, especially when runing on systems where you rewrite many files often (for example logging).

Then I would have lost both my SSDs by now if 1-2 years was realistic. Honestly I haven't heard about this problem before do you have any links? Because the calculations and programs I have seen will put most SDDs at daily usage of around <10 GB/day at around 8-10 years continuous use.
SSDs are for OS and programs, HDDs are for storage, for the regular consumer anyway.

You know, from Sony's description of the disc, it sounds like they're not marketing it towards regular consumers who want to put a movie on it, but rather at industrial scale use; as they say, for cloud storage capacities, movie makers, etc.

In which case, I guess it makes more sense to create a 300GB disc in the online storage day-and-age? Though I wouldn't really know, considering I don't have a clue how those things work

thats the thing. on paper SSDs are great.
In realiy, modern SSDs have a 2000-3000 writes burnout as opposed to the hailed 100.000. IF you didnt loose your SSD after 2 years, you either did not use it a whole lot or just got lucky. i got a HDD that spins for 10 years now, does not mean average HDD life isnt 3-5 years.

Ok, let me rephrase, I haven't heard about SSDs failing in the numbers you are describing and I read about 6 tech sites almost each day.
Also the 100k is for some of the early generation Single Level Cell NAND.
And as I said earlier those 1000-3000 writes for MLC is at a 3% failure rate, so at 2000-6000 writes the failure rate would be 1-(1-0.03)^2 ~ 6% failure rate.

While the tech-porn side of my brain gets all warm and fuzzy at this the logic sides questions this. Sony while having a mountain of financial problems flushes even more resources into a system of extremely questionable value. This isnt the 90ies anymore, with disks being the end-all of the market. While many lacks access to high speed digital the market is a lot more divided these days and trying to get back the DVD boom era isnt going to benefit Sony methinks. Besides what thing are going to use that much space besides maybe 4k vids? If you want to get back in the black Sony start working on a practical holodeck.

There are no realiable failure rate statistics. as this fine article [http://www.tomshardware.com/reviews/ssd-reliability-failure-rate,2923-2.html] will show you, no relaiable failure rates are known and studies are all over the place. However user reviews and datacenters replacing them much more often than HHDs speaks another story.
And 6% failure rate is massive for data storage.

As person who has photography as hobby and shoots raw, yes my files are just huge. Working with them in the best quality after light room 4.. it is all huge.

So a 300Gbyte storage format is good news. Not joking I already switched to blu-ray for backups of my images. maybe it will take another 6 years but 300Gbyte is good news to come. Also for those who make gameplay videos, lets plays reviews, do you know how big 1080p files are? Yeah they are HUGE!

I wonder if there will be a day when there are movies and games so massive, you have to submit for written approval from your ISP to download them.
