What is an SSD (Solid State Drive), what's the difference with a hard drive (HDD)?
Now comes the data storage device replacement hard drive. Faster, high performance and lower power consumption. Functions the same as the hard drive that we know but seen from the construction is very different. His name is SSD, Solid State Drive. Currently if we buy the latest laptop or ultrabook, maybe we will be offered willing to use ordinary hard drive (HDD) or use SSD. Perhaps the following article might help you make a decision when given a choice between SSD and HDD.
What is SSD?
SSD stands for Solid State Drive or Solid State Disk, is a data storage device that uses a series of ICs as the memory used to store data or information.
SSD Components
Generally SSDs use so-called NAND-based flash memory. This is a Non-Volatile memory type. Simply put, Non-Volatile means the memory can still store data even though its supply voltage is turned off. This is a basic principle of a permanent memory like an USB flash drive.
At first, many doubted the resilience of data stored in this type of memory. They assume the data can only be stored for a few years only. Data will disappear if saved much longer. But the reality is not so especially with the latest technology. Even data can be stored safely for up to 200 years.
Comparison of SSD and HDD.
Here's a comparison table between SSD and HDD.
Components SSD (Solid State Drive) HDD (Hard Disk Drive)
Power 2 - 3 watts 6 - 7 watts
Price Expensive Cheaper
Boot time 10 - 13 seconds 30 - 40 seconds
FDE (Full Disk Encryption) FDE (Full Disk Encryption) encryption)
Vibration No vibration There is vibration
No heat produces heat Generates heat
Failure Rate 2.0 million hours 1.5 million hours
Read / write speed Generally 200 MB / s, even 550 MB / s for the most advanced SSD. Between 50 - 120 MB / s
Notebook Capacity: less than 1TB
Desktop: Max 1TB
Notebook: 500GB - 2 TB
Desktop: 6 TB
Noise has no moving parts so it does not produce noise No moving parts to produce noise
File opening speed 30% faster than HDD Slower
Impact Style Magnet SSD is safe against magnetic force impact Magnetic force can erase data.
Conclusion
From the table above shows the advantages possessed by SSD to HDD. Nevertheless all passed away to you. For simplicity, we give the following conclusions.
Choose who uses HDD if:
• Requires more capacity, up to 6 TB
• Do not want to cost more
• Not really concerned about boot speed problems and open files.
Choose who uses SSD if:
• You are willing to pay for faster performance
• Do not pay much attention to capacity.
Semoga tips ini dapat membantu anda.
