Optical Disk Drives vs Flash Storage

[Guest]

Does anyone have like an estimation of when optical drives will be out dated and everyone will stop using them and/or producing the materials for them? Like, flash storage just seems like the best option. I really don't get why/how we're still dealing with optical drives. Yeah, I understand there's Blu-Ray and stuff, but that being said, why not just use flash storage? Or even if not flash storage, why not like a server download?

I rarely use one. the only reason people still have them is for backup or because they don't have a good enough internet connection. They will probably take 40 more years to die out. tape drives are still in use.

In the event of a global nuclear war or a coronal mass ejection, in theory, the intense electromagnetic interference could wipe most data storage types, including HDDs and SSDs/other flash memory, but good ol' optical disks should be immune.

Oh, because the image/data is burned physically?

yeah, they're actual physical things, like the grooves on a record (they're different, but it's physical is my point).  HDDs, SSDs, tape, etc are in theory vulnerable to having a bit flipped here or there.

we use them because there cheap and almost everyone has a reader. A usb is a few bucks, while a cd is a few cents.

 

For longetivity, cds are around 20-50 years, flash is a few months and hdds are around 10 years.

 

If you want a long term data storage, go tapes.

No ones uses it and its very expensive compared to tapes.

[Ithanul]

As stated, optical is super cheap to manufacture compare to flash.

 

Plus, considering the military does not allow USB thumb drives.  I highly doubt CDs or DVDs are going anywhere.  Heck, them and even large corporations still use tapes for long data storage.

Yep. Tapes are sill common. 

 

You can get 6tb tapes for about 120 USD. You can also get about 1.3PB in 23U and write at 400MB/s. Great stuff for archiving.

 

Soo

 

 

RAM = 246 cents per gig

SSD = 20 cents per gig

DVD =4.7 cents per gig

HDD = 3 cents per gig

TAPE =  2 cents per gig

Heck, Sony made one that can hold 185TB.  So, they sure not going anywhere either.

Though, that pretty darn nuts they pulled that off.

 

Same like floppy drives.  Remember having to take the one out of the computers on a C-17 for Boeing to check over the data on it.

read/write speeds?

Can't seem to find any article stating the read/write speed of it.  On the other hand did find an article where IBM and Fujifilm made one that holds 220TB.

 

Though I did find this article with a very nice comment in it where one individual goes into tape read/write speeds of current high capacity tapes.

Hi there

 

My two cents here: though pretty old technology and rather slow in terms of performance compared to flash storage, Optical Drives still have their purpose and are still widely used by many people for backups, media storage and playback and even secondary storage. It is a pretty safe way of storing data as long as you take care of the actual disk. Older technologies are still being used so I wouldn't hold my breath to wait for Optical Drives to become obsolete. 

 

Let me know if I can help with anything!
