re: Solid state memory gains on HDDs

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.

Unless you absolutely need the speed, why would you want one? I kind of want one for the peace of mind in terms of hardware failure, but I just can't really come up with an excuse beyond that. 

When I had a job as an IT guy we built several custom engineering computers (inventor 3d) with SSDs. We saw only a slight difference in the amount of time it takes to open a file.

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,

If the SDD was only 50% more and if they had the same density, I would be first in line. It may be a long time before that is a reality.

"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.

As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
