Adtron's 2.5" 96GB SATA SSD
NAND flash memory is here to stay according to iSuppli

The use of NAND flash memory in notebooks is expected to increase sharply in the next few years. We've seen the steady rise in availability of flash solid-state drives in the past few months from Adtron, Samsung and SanDisk. Dell has even gone so far as to add SanDisk's 1.8" 32GB UATA 5000 SSD as a $450 option on its Latitude D420 and a $300 option on its Latitude D620 ATG. The company is also currently offering the drive by itself for a whopping $549 on its website.

Likewise, NAND flash is used onboard in Santa Rosa notebooks as a part of Intel’s Robson initiative. Last, but certainly not least, NAND flash is also used in hybrid hard disk drives (HHDDs) which are currently shipping from Samsung.

The falling prices coupled with the increased performance in comparison to HDDs is what leads iSuppli Corp. to report that nearly 60 percent of the 40.1 million notebooks that will be shipped during Q4 2009 will have some means of flash storage onboard. "In 2003, 1Gbyte of NAND flash memory was nearly 100 times as expensive as an equivalent quantity of HDD storage, according to iSuppli. By 2009, that price gap will dwindle to a factor of slightly less than 14," said Matthew Wilkins, principal analyst for computer platforms at iSuppli.

iSuppli projects that 54 percent of the ultra-portable notebook market will feature HHDDs while 28 percent will use SSDs by Q4 2009. 58 percent of mainstream notebooks will use HHDDs while 25 percent will use SSDs. Ultra-portables and mainstream notebooks account for 10 percent and 57 percent respectively of overall mobile PC shipments.

Recent research from DataQuest shows that SSD pricing will steadily decline in the next three years. Currently, 1.8" SSDs are five times more expensive as traditional 1.8" HDDs. By 2010, SSDs will be roughly three times as expensive.

True, but don't forget that software will continue to consume more and more resources. By way of example, 128MB of ram was lots for Win98, 512 was enough for a minimally decent experience in XP, and it seems that 1GB is the minimum for decenct speed with Vista. Plus, as HD video/games/other sofware advances, it will require more and more resources. Eventually, people will want SSDs for the higher performance they provide. That may take quite a while, but it might happen at some point.

On a different topic: Would there be any theoretical benefit from using two SSDs in RAID, or is that benefit only seen with HDDs that have moving parts as their limiting factors?

RAID with SSD should provide a much better increase in speed than RAID with HDs since they wouldn't be slowed down by the moving parts. 2 SSDs in RAID 0 should provide nearly double the bandwidth of 1 SSD.

it is suggested that raid does not improve performance that much in real world.

it is expected that raid 0 could really boost performance in ssd devices since they lack raw throughput but have really low latency. that is why raid 0 doesn't do much for hdds (supposedly).
