Re: Capacity increasing, speed not so much?
Where money is not a problem for large multinationals and security agencies... they have no problem buying very expensive, big, really massive LTO tape libraries with RAID functions included too.
Re: success rates in restoring from tape?
You were using old digital tapes technologies, clearly.
LTO tape drives have a UBER 10E17 reliability. There is a lot of redundancy on the tapes, in the 30-40% range at least.
The tape must be seriously damaged for the drive being unable to restore data from it.
Re: Amount of time to back up to tape
LTO-6 drives are either SAS or FC (some expensive models, usually tape libraries, use Ethernet with link aggregation support).
For LTO-6 the uncompressed native transfer rate is sustained 160MB/s when reading as well writing.
Which means a 2,500,000MByte tape (actually just like with HDUs and SSD and CD/DVD/BD the real size it's base 2 not base 10...but then marketing... ) as written on IBM website: http://publib.boulder.ibm.com/infocenter/ts3500tl/v1r0/index.jsp?topic=%2Fcom.ibm.storage.ts3500.doc%2Fipg_3584_meltoworm.html
"Ultrium 6 2500 GB (2328.31 GiB)"
So it means 2,328,310 MB / 160 MB = 14551.9375 secs = 242 minutes = 4 hours 2 minutes approx
We can expect LTO-7 6.4TB tapes then to take: 6,250,000 MB / 315 MB = 19841 secs = 330 minutes = 5 hours 30minutes approx
For up to LTO-4 120MB/s standard consumer grade cheap SATA 7200rpm Hard Drives currently sold are more than enough .. even LTO-5 at 140MB/s could work...
For LTO-6 at least use two consumer grade drives in RAID-0 better on an hardware RAID controller anyway.
Obviously for professional use it's common to use no less than 8 HDUs in RAID-5 or RAID-6 .. otherwise for 16+ drives RAID-60 it's a better option. With hardware controllers supporting SSD caching then adding up to 4 SSD MLC or SLC drives for speeding the arrays up even further it's a good thing.
Re: Right, good up until the fact that only LTO-6 exists..
What? Are you serious?
LTO-7 is going to be released really soon now. Products should hit the market in a few months.
Re: 2.5:1 compression is just misleading
Yeah.. there is marketing.. BUT .. it's not that uncompressed 26TeraByte at 700MByte/s speed for LTO-9 tapes and 48TeraByte at 1.1GBytes/s speed for LTO-10 are going to be disappointing at all... !
That is more than enough capacity and performance for the next 10 years.
Re: Lowest-cost archive medium
LTO drives are not consumer products. The drives are for the high-end enterprise market.
Anyway on www.pricewatch.com LTO-6 drives (not tape libraries) are in the $2,000 range right now..

Re: Glasses will outsell watches...
Like people bought 3D tv sets to watch movies and sport with glasses, right ? When that did ever happen? The fake stereoscopic 3D fraud it's over already.
You want plenty of crap apps then you buy Android devices... and 99% of Android users pirate both crap and good apps anyway...
On iOS the percentage of crap apps is really low. Some Apple rules are dumb indeed. Others are needed to prevent crap. All the privacy protection nonsense it's out of control now, at this rate developers won't be allowed to code anything anymore.
4chan .. highly likely some competitors employees ...
4chan .. highly likely some competitors employees ... behind just a nickname. The only question is which competitors... Microsoft ? Samsung? Blackberry? Google?
Competitors behind all of this...
The only question is who exactly? Microsoft? Samsung? Sony? Blackberry? Or did some of them join forces to attack Apple ?
Anyone who really thinks that just some little kids "computer wizards" geniuses are behind all of this must be really really naive.
Are you a desperate AMD employee or just a little kid on drugs ?
Keep dreaming.. your AMD FX 8-core it's slow as hell compared to an Intel Core i7.. and compared to this one it's even sillier.
RAID is dead? What a silly joke!
These guys with the marketing babbling nonsense "object storage" are just beyond silly...
So they aren't using any RAID algorithms to create and manage redundancy on the drives arrays ? Really?
I doubt that!
NAS manufacturers have been using extended proprietary RAID modes that allow to mix drives of different sizes avoiding the limits of classic RAID levels for years already...
The "object storage" revolution it's just marketing babbling. At the low level you always need to write algorithms with some very complex math like RAID.
They provide no technical info to backup their claims. If they created something so much better than RAID then they should give some low level technical info to let people understand why it would be so much better than RAID. And why it would be as much or more reliable...
But I really think that this is all just marketing b*ll here...
Re: When nobody is buying your console
The Sony 10 Million number of sold console is far from to real customers.
The real number of customers might be half that at best.
Re: Finally a standard for booting
UEFI is an excellent set of specifications. Too bad too many manufacturers are just garbage and they don't care about quality so their UEFI implementations suck. They don't pay the programmers and don't hire the most expensive the programmers to do the job properly. So the end product sucks, with plenty of motherboards plagued by the worst UEFI BIOS bugs ever...due to bad programming.
You must be on crack if you think that this AMD ARM SoC is going to be faster than Xeon CPUs...
How much is Microsoft paying for all of this ?
These researchers attacking Oracle and praising Microsoft.. it's clearly more than just fishy, it's obvious that Microsoft is paying them to do this public attack.
The real question is "who is really behind Cryptolocker" ?
... and now this partial free decrypting tool "appears" ..."like magic" ... with a statement of having reverse-engineered some private keys "left behind" ...
The question is still there "who is really behind Cryptolocker" ?
All this decrypting things looks fishy as hell... the truth will be never be known but it's obvious here some really bad things are going on...
iOS 7.x is faster on iPad2, iPhone4, iPhone4S
Upgraded many devices to iOS 7.x .. iPad2, iPhone4 and iPhone 4S became a lot faster compared to previous iOS 5 and iOS 6
Apple recently added back support for old apps on App Store...
So that customers with old unsupported devices could continue downloading the latest available version of any app previously compiled for the old iOS versions those devices are stuck at.
They need to release 250GB or 500GB discs for 8K and 4K...
HDTV became a standard thanks to the Blu-Ray and the Sony Playstation3 gave a huge sales boost worldwide.
Sony managers this time decided to steal money and release a Playstation4 fraud which is not the real Playstation4... In fact the real Playstation4 prototype it's still in Sony labs and it's known to feature a 16-core Cell 2 CPU that IBM built for Sony as well as a 500GB holographic discs unit....
If only Sony managers released that top-notch product instead of the ultra slow AMD APU Jaguar fraud along with Microsoft.. then now there would have been no issues releasing high-quality 100Mbps H.265 encoded 8K movies on 500GB discs for The-True-Playstation4 users.
So either Sony releases that prototype renamed as Playstation5 immediately and stops with the current fraud or there is not much hope for UltraHD to invade the market...
NoSQL and other crap..all scams and frauds...
A lot of marketing babbling around NoSQL and other "new standards" ... Fact is that these are far from better than SQL unlike the marketing of all multinationals behind it want people to believe.
Re: Are you sure?
It seems that you are the one not working in IT if go around telling that everyone is going Win8.x to be so productive and happy with it...
Re: Microsoft halts Windows7 support, no more hotfixes...
No feature updates it means that all the bugfixes provided by plenty of hotfixes won't be available anymore!
Not just no new features but any bug affecting performance and stability won't be fixed anymore.
Just security updates doesn't mean much if the system becomes less and less stable and less compatible with new software.
Also this will mean manufacturers will start dropping drivers support for Windows7 just like they did with WindowsXP.
This just means that Windows7, Windows2008 and Office2010 SP1 are dead.
At Microsoft are clearly completely insane, gone crazy.
Re: Time for some truly revolutionary GUIs?
GUIs need to go full 3D .. and when holographic displays and projectors will be available then browsing thru a full 3D UI will get easier and more complete.
Still the UI needs to become a full 3D environment.
Microsoft halts Windows7 support, no more hotfixes...
Microsoft has announced that it's halting support for Windows7, Windows2008 and Office2010 SP1
No more hotfixes. No more updates.
The usual shame to force people into buying worse products like Windows8.x and the upcoming Windows9.x mess
Re: According to other boffins, won't work
Those so called scientists are telling lies then. Because in other countries where there are huge mountains there are no tornadoes like there in the US. Those mountains surely do "their job" tornadoes wise.
Re: No bricks will survive category 5
He wants to construct walls not buildings nor houses.
But even a wall would be too tiny. And why just a wall ?
The cheapest thing to do would be creating giant artificial mountains. That's it. Giving those a structure similar to existing mountains, using hard rocks and metals.
Mountains don't get crushed by tornadoes. Constructing artificial giant mountains even harder than the existing natural ones wouldn't be as expensive as constructing long tiny walls with a given shape.
A mountain can have bad shapes but as long as its density it's very high it would do the job perfectly against any tornadoes and wouldn't break down. Only a volcano appearing and erupting where such artificial mountains would be built could then cause such huge things to get destroyed.
With SSD only the failure rate is sky high!
SSD failure rate even on the most expensive SLC drives/devices it's in the range of a whole sector... which means usually 512bit (a typical sector) every 10E17 bits ... which is a failure rate 512 times higher than 1 bit every 10E17 bits for enterprise class Hard Disk drives !
Re: Mostly Harmless
Elite Dangerous and Star Citizen are both frauds. Too bad people nowadays are so dumb to waste money paying for beta testing, early access... with some paying even hundreds dollars for that.
NOT TRUE AT ALL! Re: First year launch blues
That is not true at all!
When the Playstation3 was released there were exclusive titles, pretty good ones in a few months and absolutely original ones. Not converted PS2 games.
The XBox360 had plenty of original titles too.
These fake next-gen consoles Playstation4 and XBoxOne are just a scam and a fraud. The hardware is obsolete and software houses don't want to risk any money so they won't even try doing anything new working hard on such crap hardware.
A new RAID level that scales redundancy...
RAID-6 has around 30% redundancy with 8 drives .. which means that 2 can fail ...
....the problem is that if you got 16 drives that doesn't scale up to 4 drives that can fail.. you are still limited to just 2 .. BUT redundancy is still around 30% and on 16 drives that should mean 4 drives not 2 ...
THAT is the biggest design flaw of RAID-5 and RAID-6 algorithms...despite all the redundancy being used the number of drives that can fail doesn't scale up !
So you need to add hot spare drives (full redundancy) to your RAID arrays just to lower the chance of the whole array failing during rebuild.
Why the industry hasn't come up all these years with a RAID-7 standard addressing this huge design flaw it's a real mistery. The algorithms are really complex but the redundancy it's there, the design just needs to be fixed to make full use of redundancy properly scaling up with an increasing number of drives.
Re: Software house employees here, clearly...
@Simulacra75: another sheep that should go back to kindergarten .. that's what you are. Writing "troll" is not going to make scams and frauds into good things. At all.
Re: Software house employees here, clearly...
@ Swarthy: nonsense babbling .. and the kindergarten magic "troll" word...
Software house employees here, clearly...
Promoting their frauds and scams and downvoting me.
Then the sheep follow...
sheep or employee?
@B-D: what are you? Just a sheep or some software house employee? Defending frauds like that it's really naive. These are just scams. Period.
What you wrote there is just nonsense trying to justify criminal actions that these people do.
Re: Also available...
Star Citizen.. this new Elite Dangerous...
..all the crowdfunding scams and frauds going on.
All thanks to people sheep enough to pay even a lot of bucks to do the beta-testing job for free.
These software houses can get millions ripping people off so easily now.. due to so many sheep willing to pay for flawed, unfinished products.
Until a few years ago software houses were hiring people to do beta-testing. Beta-testing was an even well paid job.
Now people are so dumb that they pay to do the job for free.
Sheep! That's what you people are!
You deserve to be ripped off, obviously..
Until a few years ago software houses were hiring beta-testers, they were paying people good bucks to test every new game during alpha and beta stages.
Now they got plenty of sheep willing to waste money buying scam products, unfinished products and doing the beta-testing job for free !
Another scam like Star Citizen...
With people dumb enough to pay big bucks for alpha/beta games and virtual objects in a game that will never get fully completed and will work online only with plenty of DRM stuff....
These are just frauds!
Until a few years ago software houses were paying people to do alpha and beta-testing of their games ... Now people are so dumb and on drugs to pay even a lot of money for flawed and unfinished products with no real guarantee.
This is madness!
More cloud frauds going on...
This is just the same nonsense fraud claims by Microsoft and Sony for their fake next-gen ultra-slow consoles PS4 and XBoxOne ... Their marketing depts were claiming huge performance boost with cloud computing and so on... then they didn't even try selling that crap anymore..
This virtual GPU cloud thing it's not much different.
Unless Nvidia and VMWare will be connecting each customer building with no less than 1,000Gps internet connections... it's just a fraud.
No internet link either now and for the next 15 years or so will have enough bandwidth a low latency needed to achieve the claimed performance. Both for consumer and high-end enterprise products.
VGA ? What? VGA was introduced in 1987 with the PS/2 ...
There was no VGA graphic card in the old PCjr or any other PC at the time.
PCjr models were using Motorola 6845 graphic chip which was an enhanced CGA.. not even EGA yet.
Asking the police to help for criminal currency...
People are completely out of mind nowadays.
The whole Bitcoin and cryptocurrencies are a huge fraud created by bankers.
It's all illegal. No taxes are paid on this money. There is no control. It's just dirty black market.
It's what bankers wanted to steal money quicker from people and move legal money from banks too.. so still stealing from people worldwide anyway.
Bankers must be jailed. And all the politicians that work with them and help them stealing money from people.
Re: 2300 light years distance.. just 4 years to change anything from here?
"Sorry, your argument from ignorance does not advance the conversation.
I suggest you read up some science regarding the Transit Method of detecting exoplanets.
I also recommend you consider downloading the Exoplanets app, a visual and interactive catalogue of all known exoplanets."
You are the ignorant one here. Thinking that all that babbling by the scientific community has anything to do with the truth.
2300 light years distance.. just 4 years to change anything from here?
So... these claim that they can see the movement of the planet at a distance of 2,300 light years .. and that just 4 years here on Earth by 2020 they will be able to see more of it ?
For their own official fixed speed of light rule it shouldn't be even remotely possible.
Of course there is no fixed speed of light thing..but the official science claims such a lie.
Re: Regarding Rust
The misery is with people.
There is nothing wrong with C/C++.
It's most people brains thinking to be so smart programmers that actually don't have a clue what they are doing and should be fired because they are not real programmers at all. Most programmers are just arrogant ignorant people.
True programmers are a few.
When any C/C++ code includes "goto" you know it sucks...
This just proves how well written the open-source Linux myth software is written... Ancient code, sloppy design.. just beyond bad.
Yes, there still is goto in C but anyone using it should have his/her brain checked. Clearly doesn't have a clue how to write proper C/C++ code.
Re: Crappy PR picture
A 120" top-notch projector screen can be bought in the $1,800 - $2,600 price range.
Anyone buying a $30,000 - $40,000 projector surely could buy a $10,000 screen anyway.
Re: Apple maps - could be worse
Google was requesting money from developers to use and include their maps services in the apps. And they kept asking more and more money raising prices over and over.
Apple did the right thing to ditch Google.
Low-level "arcane" nonsense...
