Will solid state drives replace conventional harddrives ?
A few notes on the previous answers. The “guy” who predicted “power will double every 10 years” was Gordon Moore, cofounder of Intel. This is referred to as Moore’s Law and it states that processor speed will double every 10 years. This was true up until about 10 years ago. We have reached the point where the CPU frequency has been pretty much maxed out, so the trend is now to add more processor cores per die. Hybrid SSD’s came out several months ago and have failed to meet the performance expectations so more research is needed in this area. Basically, it is inefficient and financially unjustifiable to use SSD’s for storage. Their main advatage is lower seek times which makes them very suitable for using in large databases, as well as using them for boot drives. They do not perform well in a RAID configuration, since placing them in any array will disable TRIM which will cause a dramatic decrease in performance over time.
It isn’t certain that SSDs will replace conventional, rotating drives. For mass storage, where speed isn’t as much of an issue, a standard HDD will still be much cheaper per GB than an SSD will be. Furthermore, HDDs can be fast enough as compared to the rest of the system. I recently read that hybrid drives – drives with some SSD storage and the rest HDD storage – should come to the market at the end of this year. They were supposed to look like one logical drive, but the controller would shift files over to the SSD part if they were in constant demand. That’s one very interesting hybrid approach that I’d like to see. Heck, I might even buy that for my own laptop. @jack of all trades: Not quite true. Moore’s law is about the density of transistors, and that it doubles every 18 – 24 months. It just so happens that this tends to correspond to a similar increase in computing power, but that’s not necessarily a given.
Yes the old spin platter drives will be replace within 4-7 years and by that time the ssd drives will be lower in price and higher in gb’s, for example vcrs started out at 1000 dollars usd as time went pass prices drop and and now almost completely disappear off the market ,replace by dvd players and blue ray players,econ 101 the old basic supply and demand
