Non-Removable Storage Technology:
Samsung Will Ship a 256GB Solid State Drive This Year!

Summary: Many industry experts predict sold state drives will replace disc-based hard drives.

SEOUL (AFP) - Samsung Electronics Co said it has developed a new solid-state drive which is expected to replace hard disk drives in laptop computers.

Samsung said its 256-gigabyte solid state drive (SSD) for data storage is 2.4 times faster than traditional hard drives. The company plans to begin production of SSDs this year. The new SSD "represents a bold step in the shift to notebooks with significantly improved performance and larger storage capacities," the company said in a statement. Samsung described the new SSD, 2.5 inches long and 9.5 millimeters thick, as the world's smallest of its kind. It can read up to 200 megabytes of data per second. It said, citing market research agency iSuppli, that 35 percent of notebook computers would use the SSD by 2012.

Many industry experts predict sold state drives will replace disc-based hard drives and offer better preformance both in speed and reliability. Disc-based hard drives have moving parts and are more susceptible to damage than a solid state device. Will SSDs offer the next big performance increase for PCs?

Still the main drawback is not technology... but price !
Hope it will reach a reasonable level of cost as it will be more sold around the world...
Whatever, this is a good news for people wanting better data storage hardware performance. When accessing a hard drive will be as fast as accessing a RAM, caching and buffering will be changed.

Agreed. But all technology drops {#twocents} so yeah, for now, hard drives offer more bang for the buck but I predict that in five years or so, most new computers will come with solid state drives. I think

USB drives have a limited write cycle of a million writes or some huge figure, but will we see the write life of these memory units exceeded and last like some hard-drives that have lasted for over ten years?

At first sales happen, the price they will be asking for the new technology may be a decider unless the specs are truly spectular.

There have been successful attempts to use CF style cards to replace hard-drives in little units like the Libretto's and it saves power although writing is slower in most cases.  It be good to start to implement the memory solutions they currently use in low gig (not hard-drive) devices and make them available for Laptops where G-force and other damaging environments won't be a factor anymore - These would be very cheap compared to the Samsung drive and then can be phased out when the better units come along at a cheaper price..

Either way, the memory units will become a natural part of future computers so we better be prepared for it.

>>USB drives have a limited write cycle.....some hard-drives that have lasted for over ten years?

Great point Allen. The "Write Endurance" (the number of write cycles to any given block of flash memory for flash drives) is limited and the lifetime of a hard drive is also limited. Both hard drives and solid state drives (flash drives) will fail. Some sooner, some later. A good backup strategy is critical if your data is important to you. {#alert}

The actual longevity of a flash drive isn't tied directly to the cycle rating because computers don't always write to the same location. Meaning, with a 256GB SSD, although the cycle rating might be something like 2 million, that's 2 million cycles to a specific block of memory. So if a computer writes, deletes, writes, deletes, etc., it will not write to the same location every time so under typical scenarios the longevity of the drive will be longer than the cycle rating. How long? Not sure but your "guesstimate" above of 10+ years seems in-line with what others are writing. It'll be interesting to see in the long run which will be more reliable in real-world situations.

Here are some interesting resources on the subject:

SSD Myths and Legends "write endurance" - http://www.storagesearch.com/ssdmyths-endurance.html
Indicates in 1994 flash drives failed at about 10,000 cycles and in 1997 about 100,000 cycles, and in 2006 about 2 million.

Debunking Misconceptions in SSD Longevity - http://www.bitmicro.com/press_resources_debunking.php
Contains data for a specific endurance test. The test they discuss indicated a 64GB SSD with a cycle rating of 2 million will last 50 years when deployed in an enterprise server application! That's hopeful.
