Features and specifications: Product description： Capacity ： 128GB 256GB 512GB 1TB Material: Plastic Read Speed (MAX): 550 MB/s; Write Speed (MAX): 500 MB/s. Compatible Systems: Windows 11 / 10 / 8 / 7 / Vista / XP, Mac OS X, Linux Applicable equipment : Desktop computers, laptops Operating temperature ： - 13°F to 185°F (- 25°C to 85°C) Storage temperature： - 40°F to 185°F (- 40°C to 85°C) Size: 100*70*7mm 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.
