1.Q: What is the difference between SSD and HDD?

   A: Both are storage devices. but SSD with better effectiveness , especially its random access speed significantly ahead of HD. But with higher price, so more suitable for operating system  installation on the practical application. The HDD with lower price and slower speed. usually been used as storage for data backup.  

2.Q: When i restart my computer. I realized that the SSD storage become largger or smaller sometimes. is it any problem with the SSD?

   A: When the operating system boots, there will be job data be written in the flash disk, so there will be different  larger or smaller storge condition due to the differenent condition of the flash disk.  So you will find the remaining capacity be slightly larger or smaller, this is normal circumstances.

3.Q: How to use the SSD properly to well protect it?

   A: Currently, the SSD average erasure feature and built-in error correction mechanism can increase  the SSD lifespan.  But in general, SSD lifespan depends on the how  it is been used and the work environment, if mass and long time large numbers data been written or been used under high-temperature environment . which would likely to reduce the SSD lifespan.

4.Q: How to divide SSD?

   A: In Windows XP, for example, you can divide SSD through the Control Panel / System management Tools / Computer Management / Disk Management, select the installed SSD, and press the right mouse button, press add new disk to complete.

5.Q: When open the file. the file name or content becomes garbled, Why this happen?

   A: It is the contact problem usually, you can re-plug and make sure SSD interfaces and computer interface contact effectively .

6.Q: What are the determinants of the SSD? seed?

   A: The overall performance of SSD are decided by the hard drive interface (SATA, IDE, PCI-E, etc.), the controlling IC (program), loss of efficiency (firmware),  balancing algorithm, the original Flash bandwidth and the circuit design and manufacturing processes of the PCB board.

7.Q: What does the 2 Channels 4 Channels 8 Channels 10 Channels mean?

   A:It means the qty of chips of read and write data at same time. 2 channels means 2 chips do reading and writing.10-channels means 10 chips in reading and writing at the same time, depending on the management capabilities of the controlling IC. The control IC chip of INTEL 10-channel can manage 10 chips read and write data simultaneously , which can greatly enhance the speed of reading and writing data to increase work efficiency . This is not a strict interpretation, just to assist those who do not understand the SSD works to understand the concept of the channel.

8.Q: Will the SSD performance degradate after a period of time ?

   A: In the earlier time. SSD donnot have TRIM function. its performance will degrade after using for some time, the garbage-collected function in TRIM can sort out the affective data and delete the useless data to get more space. this is good for data reading to ensure SSD in relatively good condition. you can try to use HDD Erase to restore the original performance. but we would suggest you not use too often as it will have some degree defect on the flash chips.

9.Q: For the IDE SSD. When open the file. it is a little slow? why this happens? How to solve it?

   A: It is compatibility issues mostly, you can try to use the new version software to open the file.it can often solve the problem.

10.Q: The SSD indicator is flashing always, constantly read the disk, is it a performance failure?

     A:You can judge by two steps:

1, This phenomena occurs before entering the system: please check if the motherboard and SSD are fully contacted. or to test one more time with another SATA data cable
2, This phenomena occurs after entering the system, check if any software in the operating system is reading and writting the SSD. Like antivirus software, system restore, virus, Trojan horse, and so on. after that turn off background procedures to test again.
