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
SATA1 (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.
SATA2 (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.
SATA3 (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 .
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.
OtherwiseSSD 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.
