Solid state drives have always been the best pick compared to regular hard drives. SSDs, which use flash memory to store data, tend to be faster, have no moving parts to replace or wear out and use less energy than regular hard drives. The one difference that hurts SSDs has always been the cost. Purchasing a 128 GB SSD could get most people several 2 TB regular hard drives.
Nathan Su, flash memory sales director at Kingston, says the average price of 1GB of NAND flash memory will probably fall to around $1, according to DigiTimes. Su readily admits that the high cost of flash has hampered SSD adoption, but he believes the transition to 19nm and more advanced manufacturing processes will prove a game changer in 2012.
One unexpected factor for hard drive prices has been the recent floods in Thailand which have caused regular mechanical hard drive factories to shut down or curtail production. This has caused a shortage in hard drive as well as a price jump for the remaining drives that are still for sale. The prices for some hard drives may not go back down to pre-flood levels until the end of 2012.
