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)?
USB flash drives, SSD drives, computer RAM,hybrid drives (small SSD + hard drive) and graphics cards. Sources: 5 years of working in a PC store.
somewhere in the 20th or 21st century
Solid State Drives (SSD) are more robust that traditional magnetic drives. They dont have any moving parts and generate less heat during operation that magnetic drives. They are also not vulnerable to strong magnetic fields which magnetic drives are. They use less energy in operation as they have no moving parts. On the downside SSD's are susceptible to degradation over time and cannot be physically defragged (as magnetic drives can be).

Bügelmeister: Hello The Pug: I was wondering, what is the advantage with SSD drives?
The space inside the computer for DVD/CD/Floppy(who uses these anymore?) Drives and also Solid State Drives (SSD) and Hard Drives.
Platter-based drives have a different reading system which is faster than a typical SSD.
ide hard drives are the old, slower, less capacity drives. sata are the modern, faster, large capacity drives. and ssd are the new, MUCH faster, medium capacity drives. ssd stands for Solid State Drive. it has no moving pieces inside. its basically a flash drive but in hard drive form. ssd's are also very durable u can drop them and they wont be damaged. ide drives have moving parts in them therefor the read/write head can scratch the disk easily if it is dropped and if shaked very hard it cna be damaged also. ssd's are VERY expensive though.
There are a few advantages of buying a SSD drive such as less power usage, faster data access and higher reliability. You can get an SSD drive at any computer store such as Best Buy.
With capacities beginning to exceed 12TB, SSD provides the largest capacity by far. HDD (hard-disk drives) are not all that far behind but the high cost of high-capacity SSD puts them out of reach of most users. Both SSD and HDD can be configured as RAID allowing even greater capacities, but in terms of cost per megabyte, hard-drives still offer the greatest capacity (SSD is typically 10 times more expensive). However, that will change as the cost of SSD continues to fall. Flash drives use similar technology to SSD but on a much smaller scale, comparable to quad-layer BluRay discs which are capable of storing up to 150GB. But, as with SSD, we can fully expect flash drives to offer much greater storage capacity in the future, albeit to a lesser degree than SSD.
