Flash memory is starting to be used in equipment that's not necessarily mobile or small, specifically challenging the hard disk drive in PCs and even enterprise servers in the datacenter.
As mobile technology has gained steam, it raised the profile of solid state memory. The use of NAND flash chips in mobile phones and other mobile devices makes sense because of the lower power consumption, lower space requirements, and increased ruggedness of semiconductor memory, even though the chips are least 50 percent per gigabyte more expensive than traditional hard disk drives.
Now that pricing limitation seems to be evaporating. According to market research company IHS, solid state disks (SSDs) will account for more than a third of worldwide PC storage shipments by 2017, about seven times what they are today. SSD shipments in PCs will rise to 227 million units in 2017, compared with 31 million in 2012, while shipments of PC hard disk drives will fall 14 percent, from 475 million in 2012 to 410 million in 2017.
I have read of other programs running much faster and boot up times being significantly better with an SSD. I would be very curious to know what others experience was with SSDs relative to the normal types of software performance, please add your comments on the speed up/down and what software was running.
While flash SSDs are taking over some HDD apps here and there, te need for HDD storage for all those facebook and Google photos is exploding. The net result: HDDs are doing pretty darned good these days.
I would love to run with a SSD but given the real world cost comparison with HDDs unless I need the speed I can't afford the cost.. I can however get my employer to spring for the improvement in speed and performance. Some day when the cost comes down I will be first in line for one, but for now..
Bytes per Buck:
A 250 or 500 G drive is enough for me to run windows on very nicely.
SSD's are preceived as better than HDD.
Once SSD's hit the point that they were 'affordable' , then they take off.
as they have.
less than 1 $ per GByte, seems to be the tipping point,
"That pricing limitation seems to be evaporating"? NAND ASPs are up significantly lately, so that seems highly unlikely. SSD's are being adopted due to size, speed, and power consumption, not price, and it will probably be a long time, if ever, that the price threshold is crossed. The 50% higher number seems a bit odd as well. Go to Newegg...a 500GB drive is about $400 for SSD vs about $70 for HDD. Percentage...hmm...that's about 450% higher. Obviously features besides price drive market share, and it would be good if the article delved into those market dynamics rather than making false statements about cost.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
