Disadvantages of SSDs.

Answer 1

High cost Limited number of read write cycles Smaller storage capacity compared to HDDs

Answer 2

Runs slower, less storage space

Comment:

This is not true, solid state drives run significantly faster than hard disk drives (HDD), which are physically limited by the rotational speed of the motor and the data distribution on the tracks. On HDDs outer tracks can carry more information and in one turn much information can be retrieved, if its written in sequence. If written in random order (as with most files) more spins have to be made in order to retrieve data and when the HDD gets filled up and writes are done on internal tracks, the data retrival speeds further decline.

With SSDs its a whole different scenario. There is no spinning platter, only the controller who allocates data. Since there is no rotational components, limiting the data retrival speed, SSDs do a much better job in write and reading data than HDDs.

To give you a few examples:

A 15K RPM SSD generally provides:

200.0 MB/s read & write for sequential data blocks

1.2 MB/s for random 4k block read & write

A OWC Mercury Pro SSD generally provides:

285 MB/s read & write for sequential data blocks (limited by the 300 MB/s max. datatroughput of the SATA II interface)

50 MB/s for random 4k block read & write

A good source explaining the details about it can be found on Wikipedia or SSDeurope

Answer 3

There are lot of advantages for solid state drives over conventional drives (ie SATA/PATA/IDE). Main advantage is there is no moving part in the solids as compare to others. moving parts causes the most failure in drives. solids are much more more faster drive then a 7200 RPM (moving part) drive..

Answer 4

Solid State Drives (SSD) are faster at data retrieval, have no moving parts and are also usually small and lightweight. Disadvantages are mainly the fact that SSDs are very expensive compared to normal hard drives (HDDs). In the past, there was also more concern over whether or not flash or solid state memory would hold information for long periods of time (years and years) successfully, but the technology has been improved to the point where this is becoming less of a concern. Eventually, it is highly likely that SSD technology will come down in price and the old hard drives will be incredibly cheap.

Answer 5

Data can be read and written at an extreamly fast rate.
