Read before purchasing: Our speed test on specific configuration desktops use SATA3 interfaces/SATA3 cable without an operating system. Test results are just for reference. SATA 3.0 SSD tested on SATA 2.0 interfaces and SATA 2.0 cables will have a speed lower than 300MB/S ,Laptops will be unstable and lower than desktops. Different test platforms and test software versions may have different results. According to the international standard 1000 KB = 1 MB. (Real capacity: Capacity x 0.93). example 120G x 0.93 ≈ 111.6(maybe) Specifications: Interface and compatibility: Serial ATA(SATA) SATA revision 3.0 (6 Gbit/s, Serial ATA-600) SATA revision 3.1 SATA revision 3.2 SATA revision 3.3 SATA revision 3.4 ——————————————————- SATA revision 2.0 (3 Gbit/s, Serial ATA-300) SATA revision 2.5 SATA revision 2.6 ——————————————————- SATA revision 1.0 (1.5 Gbit/s, Serial ATA-150) Supported systems: Windows 10/8/7/XP/2003/2008 Linux (Various distributions example Redhat Ubuntu Debian…) Unix Application: Support SATA Interface desktops,notebooks, mini computers, all-in-ones, and other commercial PC High quality: strictly tested one-by-one Best service: Direct service from factory Lowest price: Factory sell directly Quality warranty: Enjoy free replacement for three years Contact us: 1,Our working time 6:00 P.M – 3:00 A.M ( Pacific Time ), Monday to Saturday ,Except legal holidays. 2,Please contact us with AliExpress message only. 3,Due to the time difference between countries, we will reply as soon as we receive the message . 4,If you are stratified with our items, Please leave us your positive feedback. 5,Please don’t leave negative feedback before contacting with us. We will do all we can to solve your problems. Submit negative feedback is not late if the problem is not solved. Notice： 1, Our test result is base on sataIII interface,sataIII sata cable,desktop and SSD empty status , different computer and software (include software version), the result may different . 2, Difference between SATA I, SATA II and SATA III SATA I (revision 1.x) interface, formally known as SATA 1.5Gb/s , is the first generation SATA interface running at 1.5 Gb/s. Max speed 150MB/s. SATA II (revision 2.x) interface, formally known as SATA 3Gb/s, is a second generation SATA interface running at 3.0 Gb/s. Max speed 300MB/s. SATA III (revision 3.x) interface, formally known as SATA 6Gb/s, is a 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 sata3.0 SSD tested speed on sata2.0 interface and sata cable the result will be inaccurate. 3,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 .
