The order was there inerhalb of 4 days. Built in an Acer Laptop R4 with existing mSSD port without problems because screws were present with me. Windows 8.1 in the Disk Management tool has recognized the SSD immediately. Moving from Windows to the SSD has good geklapt with free partition programs on the Internet (Backup all important). With the SSD, the boot process is actually faster. Although this is not a Samsung Evo, the access times for an SSD even for the price ok. For those who dare more: at the manufacturer's website, there is a current firmware. The site is indeed in English, a guide is also available in German.
