Is there any way to access the other 70gb of theoretical storage space within Windows?

No, I don't think you understand this.  THEY ARE DIFFERENT UNITS OF MEASUREMENT.  This is important.  It's not that the storage is unused, it is MEASURED WITH A DIFFERENT UNIT.  Hard drive manufacturers use ONE unit and the OS is using a DIFFERENT unit.  There us no unused space.

Right, sorry, I actually totally forgot that part. The little asterisks on drive packages flash to mind.

i5 6600k and GTX 1070 but I play 1600-900. 1440p BABY!

Still, don't put too much faith in my buying decisions. xD

You find me another way to fit 330TB on something no bigger than a regular 3.5" HDD.

That's cool for such practice. Will take HDDs to catch up, but I'm excites for SSDs advancements.

How long until Linus makes a Hexabyte project with tape and then realizes it's useless to him because of how slow it is? :P

Hexabyte? Hexa = 6

fine, it's exabyte without the h... can't even make a typo these days...

 

and by the way, tera, peta, exa etc are all derived from 4 (tetra), 5(penta), 6(hexa) etc. That's the whole idea. tera -> 4 -> fourth order of magnitude.

Don't ask to ask, just ask... please 🤨

Tape is a dying media....

 

We just recently got rid of all of our tape libraries enterprise wide, now we just back up to disk, then to the cloud and our costs are 40% of what tape cost us.

 

Mechanical tape drives, libraries etc. are prone to failure (highest failure rate of any device in the data center) and the media itself degrades over time.

 

Add all that to the ridiculous write/recovery speeds and cost of off site storage / shipping of tape... good riddance.

 

My life as a SysAdmin has been much improved by removing tape from my life.

IBM and Sony have partnered together to develop a new tape cartridge that will be capable of storing 330 TB of data or ~200 Gb of data per a square inch.  For comparison, the Ars Technica article on this points out that the largest HDD are about twice the physical size of these cartridges and store 60 TB on Seagates SSD or 12 TB on HGSTs helium filled HDD, so definitely quite a bit more data density, just costs a lot more and don't expect fast read/write times out of it.  However, for long term back-up storage, this would be ideal and provides a 50% increase over what is currently available in tape storage and a 60% density increase.  As to how they accomplished such a feat:

https://arstechnica.com/information-technology/2017/08/ibm-and-sony-cram-up-to-330tb-into-tiny-tape-cartridge/

Of course, cost, as always will be a significant factor, however, large data centers that have to backup lots of data will definitely be looking into this for the benefits of storage capacity and density.

They also say Tape Drives will double every 2 years for at least the next 10 years.

How many tapes and drives did you have? We've got around 2500 tapes and 5 drives so can chuck a fair rate of data down to tape. We do D2D2T and keep a years worth of backup on disk though, as to be really old data for us to actually need to get tapes. Cost wise for us tape is much cheaper than cloud or disk storage for really long term storage.

 

You can save much more money but properly classifying your data and having realistic retention and recovery point policies, which we are unable to do >.<

what if we put 1000 tapes in RAID 0? Will the speed be any better then? xD

Late reply, but we were using 8 Dell TL4000 with 4 drives each. We had about 22,000 tapes in rotation/storage. We were rotating I believe around 200-300 tapes off site each day.

 

Now we have none :)

 

Using Microsoft's DPM software, we keep daily/weekly/monthly/yearly backups in Azure for 100% of our data now, and can recover any single file from any recovery point/date without having to retrieve, rescan, re-catalog any tapes. A typical 5mb file restore takes about 3 minutes to complete.

 

We've also increased the reliability of our long term / off site backups by a measureable amount.
