Solid state drives (AKA high-content flash storage) are far less reliable and far, FAR less time-proof than holographic storage. Holographic storage is a concept proven to be usable decades past write-date. Hard-drives become corrupt FAR before then, and flash memory isn't much more reliable than that. |

Solid state drives are in production and improving every month, last I checked I coudn't buy a holographic drive at the Best Buy at the corner of the street.
And I can drop my laptop with a solid state drive from a 10 feet height and know I will not loose any data....
And finally, who needs a hardrive that will work decades past the write date in their PC or laptop ?
Like I said this is for mass storage, not day to day useage...
PS3-Xbox360 gap : 1.5 millions and going up in PS3 favor !
PS3-Wii gap : 20 millions and going down !

It won't replace hard drives. People are not going to pay more to get the same size and read/write speeds, even if holographic shows more future promise.
The only format to overtake hard drives at the moment will be Atomic holographic nanostorage devices.
The device stores data in a complete 3D format, allowing up to 1.6 Petabytes of information per cubic CM. The first sets are supposed to ship with the volume of a cubic cm or more. Meaning around 1-1.5 ml thick or writing space. Now not only is it super massive storage, nearly 1.6 MILLION gigabytes per disc, it's read and write speeds are near 400,000 times the fastest hard drives on the market. These are supposed to ship in 2012 for 750$ per drive, 1 drive could replace whole hard drive server farms which take up whole warehouses, which costs so much to run and maintence, by 1 drive.
This will finally allow drives to have complete uncompressed data, as well as the technology can be put forward into idea such as ram etc. |
I am aware - but this is the same concept in terms of technology. Holographic storage being theoretically capable of consumer use is all that matters, here.
blu-ray isnt going mainstream yet and it wont for years yet, if it doesnt lower the price of the damn movies. paying $25 - $40 for a movie, when it doesnt look that much better isnt worth the price. i hope m$ uses this format for the next xbox though :)

this new disc will never take over blu-ray. these disc players will be so much money it wont even be funny. by the time this new disc player comes out
blu-ray plares will be 99 dollars and moives 15 dollars

Not quite. You speak as though blu-ray is the champion. It's not.
Blu-ray is the weenie making its way through the World Circuit to hopefully hit Special and then have a shot at challenging the real champion: DVD.
By the time better media is done typing in its name, Blu-ray may be the new champion or it might be stuck in the World Circuit getting KO'd by Super Macho Man.
We don't know yet.

Theres still a good chance you'll lose the laptop. 
Anyway, the real question for this technology is, what throughput will it give? Blu Ray kinda maxes out round the 40MB/S mark. If it can do 3* that, fantastic. If it can do 10* that then make way for the possible future optical standard for consoles.
Tease.
Blu-ray. ,,? do not know,god bless divix and MK.
''Halo reach''.. sell 7.m first week ,Believe¡¡¡¡¡¡
Assuming everything else remains the same I would presume that this technology will read at 10* the rate of a BRD at the same rotational speed.
Therefore if the BR drive on the PS3 reads 9MB per second, the HD read speed at the same velocity of disc will be 90MB per second minimum.
Tease.

Besides the common sense aspect? Flash memory works by charging tiny transistors with electricity. So, naturally, a little bit of electrical charge of the wrong sort will easily erase everything on your flash memory. Don't believe me? Do it yourself - take a flash memory card, expose it to a non-controlled charge of electricity, and try using it again.
And actually, upon taking the time to read some more about it, I found a variety of other ways in which flash memory is inferior. Besides the ease in completely ruining what you've got, I'll copy over some content from Wikipedia.
One limitation of flash memory is that although it can be read or programmed a byte or a word at a time in a random access fashion, it must be erased a "block" at a time. This generally sets all bits in the block to 1. Starting with a freshly erased block, any location within that block can be programmed. However, once a bit has been set to 0, only by erasing the entire block can it be changed back to 1. In other words, flash memory (specifically NOR flash) offers random-access read and programming operations, but cannot offer arbitrary random-access rewrite or erase operations. A location can, however, be rewritten as long as the new value's 0 bits are a superset of the over-written value's. For example, a nibble value may be erased to 1111, then written as 1110. Successive writes to that nibble can change it to 1010, then 0010, and finally 0000. Filesystems built on NOR flash make use of this capability to represent sector metadata.
Although data structures in flash memory cannot be updated in completely general ways, this allows members to be "removed" by marking them as invalid. This technique may need to be modified for multi-level devices, where one memory cell holds more than one bit.
Another limitation is that flash memory has a finite number of erase-write cycles. Most commercially available flash products are guaranteed to withstand around 100,000 write-erase-cycles, before the wear begins to deteriorate the integrity of the storage. The guaranteed cycle count may apply only to block zero (as is the case with TSOP NAND parts), or to all blocks (as in NOR). This effect is partially offset in some chip firmware or file system drivers by counting the writes and dynamically remapping blocks in order to spread write operations between sectors; this technique is called wear levelling. Another approach is to perform write verification and remapping to spare sectors in case of write failure, a technique called bad block management (BBM). For portable consumer devices, these wearout management techniques typically extend the life of the flash memory beyond the life of the device itself, and some data loss may be acceptable in these applications. For high reliability data storage, however, it is not advisable to use flash memory that would have to go through a large number of programming cycles. This limitation is meaningless for 'read-only' applications such as thin clients and routers, which are only programmed once or at most a few times during their lifetime.
All of these are problems that holographic data doesn't deal with.
Additionally, holographic storage works exactly like any other hologram - such as the ones on your credit cards. Holograms have withstood years upon years and still been the exact same thing. Just like a painting on your wall, a hologram is also a "picture" of sorts and doesn't change over time either. Holographic storage likely won't have any aesthetic to it, but it'll still have all the same physical properties.

@Squillium - This has been able to provide as much as 1Gbps transfer rates (125MBps). So it surpasses your estimations substantially. Check here.
