Do you know SSD?

Know your akah with SSD (Solid state drive) which is a data storage medium (storage) that uses solid state memory for data storage. In contrast to the hard disk that uses a rotating magnetic platters, SSDs use semiconductors.
Here's a picture SSD

Solid disk drive can replace traditional hard disk drives, so it is often called solid state disk drives or solid state disk, though technically not a disk. The shape and dimensions are also the same as the SSD hard drive, so it can be put on a standard slot on the computer. The drives use SATA or IDE interface similar to hard disk, so the functionality is the same.

Excellence SDD SSD Here are some advantages when compared to Disk, namely:

1. SSD power consumption less than the power consumption used HDD. This causes the SSD is more appropriately used for mobile devices. Battery from the device will be able to last longer between charging time.
2. SSD has a longer data life and more durable than HDD. If users experience a mild impact on the notebook, then data loss can be avoided.
3. SSD has a speed reading and writing are relatively higher than the HDD.
4. SSD has no moving parts resulting in less noise and heat.
5. SSD is very light weight. When compared with the HDD then it weighs 1 / 5 his.
6. MTBF (Mean Time Between Failure) or a period of time much longer life of the SSD over 2 billion hours while the HDD can only use a maximum of 0.7 billion hours.

Disadvantages SSD
In addition to the many advantages possessed SSD, SSD tenru course also has some disadvantages, namely:

1. The use of SSD has security implications. For example, encryption of data is not encrypted on a flash-based SSDs can not be done safely. Because the use of encrypted drives causes new sector is written to a different physical location than the original location at the original location so that data remains unencrypted.
2. SSD prices are still more expensive than the HDD.
3. Capacity SSD market is still limited.
4. Asymmetric performance readings with writing on the SDD cause problems with certain functions. Basically, the writing and reading operation is completed within the same timeframe. However, the SSD has a write performance is slower when compared with reading performance.
