solid state drives
Disk platters are the circular data storage components inside hard disk drives (HDDs) and some solid-state drives (SSDs) that store digital information. Each platter is coated with a magnetic material that allows data to be written and read by a read/write head. Multiple platters can be stacked within a single drive to increase storage capacity. The speed and performance of a hard drive are influenced by the number of platters and their rotational speed.
Solid state drives are drives that run off of flash memory rather than a hard disk.
Traditional magnetic hard drives use platters that spin and a magnetic head that applies negative and positive charges to the platters to record data in 1s and 0s. SSD drives are essentially flash drives similar to what is used in iPods. "Switches" in each memory "bank" are turned on and off with an electrical signal to record the data in 1s and 0s. SSD is faster because it does not have to "seek" for the location of the data on the hard drive.
If you mean between hard drives and ssd's (solid state drives), then you need to read the wikipedia page on Solid State Drives, it has a comparison of the two technologies.
Solid-State Drives (SSD's)?
Rigid metallic platters are components of traditional hard disk drives (HDDs), which use magnetic storage to hold programs and large data files. These platters spin at high speeds, allowing read/write heads to access and manipulate data stored magnetically on their surfaces. Despite being largely replaced by solid-state drives (SSDs) in many applications due to their speed and durability, HDDs still offer significant storage capacities at lower costs.
Sun's Solaris OS using ZFS is designed with solid-state drives in mind and can optimize the file structure for them.
Discs and SSDs Solid State Drives
Solid state drives, or SSD, are storage devices that uses integrated circuit assemblies as memory. Flash drives, compact flash, and MultiMedia cards are examples of solid state storage devices.
False
Solid State Drives, they are hard drives with no moving parts, they could also be compared to there cousins, RAM.
