Say "Good Bye" to HDD.

[BurtW]

Im sure HDD will be around for another 10yrs, So how many years can a SSD hold its data

People still manufacture, buy and use tape.  In fact there is still research going on to increase the data density on tape.

HDD will be around for years.

How much does a 4 TB SSD cost right now? I can get a Seagate HDD 4 TB Desktop Internal Hard Drive from the Amazon for just under $200. I don't think that the SDD will ever get this much cheap. The WD 4TB 3 1/2" Desktop Internal Hard Drive is even cheaper.

Don't ever buy them from big brand stores like Staples or PC World. You can get them much cheaper if you look around online or on ebay. I got a brand new Western Digital 4tb external hard drive for a little over £100 on ebay a while back.

i bought my 128GB kingston v3 SSD for $65 over 1 year ago. everywhere else, it was at least $80. staples has some of the best deals if you know hwo to shop with them.

buying on ebay, there's no guarantee and your warranty might be voided if it's not from a retailer.

I don't want to use Ebay anymore. In the past, I had some serious issues with them. Yes... I agree that some of the deals are cheaper than those available on the other sites... but not taking the risk anymore.

I don't know about in the USA but over here Staples is very expensive, especially for things like drives. You don't have to get them from ebay, there are always smaller stores selling them cheaper.

I actually got some of my drives from PC World's ebay store and they were much cheaper by about £20-30 than the actual in-store or online price. Came with warranties too.

maybe it's different in the UK. everything there seems to be more expensive. sucker.

Sandisk announces 4TB SSD, hopes for 8TB next year.

"We see reaching the 4TB mark as really just the beginning and expect to continue doubling the capacity every year or two, far outpacing the growth for traditional HDDs," Manuel Martull, SanDisk's product & solutions marketing director, stated in an email reply to Computerworld.

SSD prices are still too high to abandon HDD.

Yes, the prices will dive dramatically in the future.
Last time I bought an HDD the retail price was 50% lower in a little over a year.

By the looks of things I would say tapes may get a second life.

SSD is at 8 electrons per bit so only three more very very difficult doublings.  They are working on some other tricks.

HDD has HAMR, SMR, HAMR+SMR, pattern media, other tricks.

About the same horizons on both.

Not sure where you get this idea from.  SSD are NAND transistors.  Even at 20nm the transistors are 30 to 40 atoms across and each Silicon atom has 14 atoms electrons. No silicon circuit works on individual electrons.  Retrieving or writing a bit of flash ends up involving millions of electrons.  Maybe you are conflating MLC and TLC (storing two or three bits per cell) with number of electrons?  Not sure.

What issues did you have?

Once I bought a laptop from Ebay, which got damaged just after two weeks. The seller refused to issue me a replacement, saying that it was my fault. Contacted the Ebay staff, but no use there.

ebay is really unreliable. a lot of sellers who sell used shit don't put proper descriptions. recently bought a laptop and the details weren't very accurate.

Lol.....pic reply was perfect.

I have stopped purchasing anything of value from Ebay, even when they are offering steep discounts. What is the use in getting a 30% discount, when the product itself can be unreliable?

Not sure where you get this idea from.  SSD are NAND transistors.  Even at 20nm the transistors are 30 to 40 atoms across and each Silicon atom has 14 atoms.  Of course even that really isn't material.  No silicon circuit works on individual electrons.  Retrieving or writing a bit of flash ends up involving millions of electrons.

A flash cell is a special transistor with a floating gate.  It is like a very tiny capacitor.  The difference between the charged state and the uncharged state is used to represent/store a 1 or a 0 in SLC flash or on a MLC flash various charge levels are used to represent the stored information.  The floating gate itself is made of a small piece of material that may have a lot of electrons but it is the extra electrons that are pushed on the gate when charged that I am talking about.

I am a bit mad at myself because it looks like I was wrong.  I could have sworn I had a reference that showed that sub 20nm flash was sub 10 electrons on the floating gate in the charged state.  I cannot find that reference.  The reference I did find here:

http://www.eecs.berkeley.edu/~tking/theses/whkwon.pdf

in figure 1.14 still shows 10's of electrons on the floating gate all the way down to 10nm.

My point that the feature size does have a physical limit is valid and eventually we will run into this physical limit.

The absolute limit for this technology (storing information by charge on a floating gate) would be one electron per bit.

[BurtW]

Found the source of my confusion and memory lapse.  The sub 10 electron number was not the total number of electrons on the floating gate.  It was the number of electrons that cause a 100 mV shift.  See page 7 of this reference:

http://www.flashmemorysummit.com/English/Collaterals/Proceedings/2012/20120821_TA12_Yoon_Tressler.pdf

It shows that at a 10nm feature size a loss of less than 10 electrons causes a change of 100 mV.

The above presentation is full of very interesting statistics related to flash.

i don't like ebay's fees for selling either. exorbitant fees. it's going to be something like 14% of your revenues.
