Question and Answer:

 

Q:Why the capacity of SSD displayed in the computer will be less? Is it normal?

A:It is normal situation, capacity of storage products are usually in accordance with 1MB=1000KB,1GB=1000MB calculation, but the operating system using binary algorithm: 1MB=1024KB, 1GB=1024MB, which is a normal calculation range.

Storage device conversion formula:  nominal capacity X 0.93 =actual capacity

Actual capacity is not totally equal to nominal capacity. For example, 1GB(1,000,000,000 Bytes) may display as 0.93GB (1,000,000,000Bytes/1024/1024/1024=0.93GB) in the OS(operating system) due to different computing method. Meanwhile, actual available capacity may show less in the OS as some capacity is reserved for firmware in SSD.

 

Q:How to make  format and 4K alignment?

A: It is recommended to use WINDOWS7 or above operating system which are with built--in disk management formatting function, it can achieve 4K alignment(recommended NTFS disk partition format), you can also use DISKGENIUS partition tool to make partition. After you get into PE, you find the partition tool, Open - fast partition - select SSD - you can customize several partition, and finally select 4096 to click OK. Make sure your computer is running under AHCI mode, otherwise SSD's write/read performance and response time will be affected. Use AS SSD Benchmark to check if SSD has complied with 4K Alignment and already been under  AHCI mode.

 

Q: Why can't we find SSD Hard Disk and Read/Write Data?

A: The newly bought SSD generally needs to be  formatted in Disk Management, after that you can write and read data, it is recommended to make format in the WINDOWS operating system and use  NTFS format.

 

Warm Hint:

 

1. Keep away from water, dust, high temperature as it will be damaged if used incorrectly.

2. Between the manufacturer and the Windows system / other common computer system, because of the existence of the algorithm, the actual capacity is slightly smaller than the nominal capacity.

3. Storage device conversion formula: nominal capacity X 93% = actual capacity

4. Before you use it please do the  format and partition firstly, find it like this

 "My computer-Management-Device manager-Disc drive", otherwise, your device can't read it!!!

if your device can read it once you insert it into, that mean it's not new!
