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

∙ 13y agoThere 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..

∙ 10y agoSolid 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.

What are the disadvantages of solid state drive?
The disadvantages of solid state drives are few if you discount the price. Smaller writes are generally somewhat time-inefficient, and near-full SSDs cannot be written to quite as quickly. Post-creation encryption is extremely difficult, so make sure your data is encrypted when you write it, and not after.

Perfect disk, they even claim that it supports SSDs.
Where can cheap SSDs be found?
Solid State Drives, or SSDs that are inexpensive can be found at online sites such as Ebuyer or Amazon. It is also a god idea to check weekly advertised specials at electronics stores such as Best Buy or Fry's Electronics.

How do platter based drives compare to SSDs?
Platter-based drives have a different reading system which is faster than a typical SSD.
Is the SSD currently a viable alternative to a HD?
Only for small devices such as Netbooks that aren't intended to store large amounts of data. One of the biggest problem with SSDs is the cost/storage ratio. The cost per Mb for SSDs is much much greater than per Mb for HDDs. Probably the other biggest problems with SSDs is the limited erase/write cycles that are available for each storage block on the SSD. They can only be erased a certain number of times before they wear out... leading to a gradual diminshment of overall storage capacity as blocks become unavailable. This applies to USB storage too! One of the good things about SSDs is that with no moving mechanical parts, the risk of drive failure is dramatically reduced (which is one of the reasons for their use instead of HDDs for space and military applications).
What type of memory is solid state drive?
SSDs use Flash EEPROM to simulate the operation of a hard disk drive, without moving parts.
What are the Major Differences Between SSD And HDD?
The major difference between SSD and HDD are as follows: Technology: SSD (Solid State Drive) uses NAND flash memory with no moving parts. HDD (Hard Disk Drive) relies on magnetic storage and spinning disks to read and write data. Speed: SSDs are significantly faster than HDDs. They have quicker read and write speeds, leading to faster boot times, application launches, and file transfers. Durability: SSDs are more durable due to their lack of moving parts, making them less susceptible to physical damage from shocks or drops. HDDs are relatively more fragile because of the delicate spinning disks and read/write heads. Power Consumption: SSDs consume less power than HDDs since they do not require energy to spin disks or move read/write heads. Noise: There are no moving parts in SSDs, so they operate silently. HDDs produce noticeable noise due to the spinning disks and read/write head movements. Heat Generation: SSDs generate less heat during operation than HDDs, contributing to improved system cooling. Capacity: HDDs generally offer higher storage capacities than SSDs at a lower cost per gigabyte. SSD capacities are improving, but they are still relatively more expensive for larger storage options. Fragmentation: HDDs can experience file fragmentation over time, which may lead to slower performance. SSDs do not suffer from fragmentation issues, resulting in consistent performance. Lifespan: SSDs have limited write cycles per cell, which may affect their lifespan over long-term usage. HDDs can potentially last longer as they do not have such limitations on write cycles. Data Recovery: Data recovery from a failed SSD can be more challenging and expensive due to the complexity of NAND memory chips. Data recovery from a failed HDD can be relatively easier and less costly, as it involves mechanical repairs.
