FAQ
Q1. Why the capacity displayed from PC is smaller than original capacity?
A1: Actual usable space maybe less than the total storage capacity listed due to decimal measurement used to represent usable capacity of the SSD.
Actual capacity calculation: Total storage x 0.93

Q2: How to format SSD and achieve 4K alignment?
A2: Win 7 or higher version OS is recommanded due to "Disk Management". Formatting function is built in the systems. We recommend NTDS Disk partition format 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 alignment and already been under AHCI model.
Q3: Why can't we find SSD hard disk and read/ write data?
A3: The newly bought SSD generally need to be formatted in Disk Management before using. It is recommand to format in the windows operating system and use NTFS format.
