Note:

1,Our test result is base on SATA 3 interface, SATA 3 sata cable, desktop
and SSD empty status, different desktop and software (include software
version), the result may be different.

2, Difference between SATA 1, SATA 2 and SATA 3

SATA 1 (revision 1.x) interface, formally known as SATA 1.5Gb/s, it is the
first generation SATA interface running at 1.5 Gb/s. Max speed 150MB/s.

SATA 2 (revision 2.x) interface, formally known as SATA 3Gb/s, it is the
second generation SATA interface running at 3.0 Gb/s. Max speed 300MB/s.

SATA 3 (revision 3.x) interface, formally known as SATA 6Gb/s, it is the
third generation SATA interface running at 6.0Gb/s. Max speed 600MB/s.
This interface is backwards compatible with SATA 3 Gb/s interface.

If SATA 3 SSD tests the speed on SATA 2 interface and sata cable, the
result will be inaccurate. According to the international stander
1000KB=1MB ,the real capacity =Capacity x 0.93, please notice that .

Before you use it please right click "My computer-Management-Device manager-disc drive" and can find our SSD. Please do the format and partition.

FAQ

A： Why the capacity displayed from PC is smaller than original capacity?

Q：Actual usable space may be less than the total storage capacity listeddue to Decimal measurement used to represent usable capacity of theSSD. Actual capacity calculation: Total storage x0.93 Factory default setting 1GB=1000MB=1000000KB=1000000000B Computer system setting:1GB=1024MB=1048576KB=1073741824BExample: 360GB SSDFactory capacity:360×1000×1000×1000=360000000000B Transfer to PC displayed actual capacity 360000000000B/1024/1024/1024=335G Fast calculation: 360GX0.93=335G.

A：How to format SSD and achieve 4K alignment?

Q：Win7 or higher version OS is recommended due to 'Disk Management Formatting function is built in the systems. We recommend NTDS disk partitionformat and DISKGENIUS tool to make drive partition.PS: Please make sure your PC system runs under AHCI mode.Otherwise SSD write/read speed performance and response time will be affected. Use as SSD Benchmark to check if SSD has complied with 4K Alignmentand already been under AHCI Model.

A：Why can't we find SSD hard disk and read /write data?

Q：The newly bought SSD generally need to be formatted in Disk Management before using. It is recommended to format in the windows operating system and use NTFS format.

Notice:

About capacity:

64GB=approx. 55GB

120GB=approx. 111GB

128GB=approx. 119GB

240GB=approx. 223G

256GB = approx. 238G

480GB = approx. 446GB

512GB = approx. 476GB

960GB = approx. 892GB

1TB = approx. 930GB

2TB = approx. 1800GB

The hard disk flash memory supplier is using the decimal algorithm: 1MB = 1000KB, calculated 1G = 1000MB,

But the operating system is using a binary algorithm: 1MB = 1024KB, 1GB = 1024MB.

Therefore, there are some differences between the display capacity and the nominal capacity of hard disk/flash memory products.

However, this is allowed. Please don't doubt his authenticity.
