"Plug-and-play" is here to be taken literally.

Ordered by Morningstar Express ... the next morning at 09 clock, the SSD was there. Getting enthusiasm!
Then after opening disappointed face ... I have yet to appoint a RAM ... A closer look again more closely ..
Oh that's the SSD looks like in the picture. Unbelievable how this small 1.8 inch mSATA is.
The joy rose again ..
Then the All-in-One PC packed and locates the slot. How fortunate that I had previously occupied.
The card is inserted, brought the screws from the bag and what can I say ... they fit right away.
So no additional order or consideration, where can I get suitable screws. At HP they fit!

After closing the lid and boot up the computer with the existing 1TB drive, the 120GB SSD is also recognized under Win 8.1 right away.
Now only the Paragon Software "OS to SSD" used, changed the boot order and after 15 minutes the computer booted already the first time from the SSD ....
Result. Installation 2 Minutes, porting of the operating system for 15 minutes. Result: complete satisfaction! That's how I imagined it with a SSD! From switching on the computer, to the call of various programs my computer now needs only about 18 sec. Class!
For me, the mSATA is worth your money and achieved full marks. Strong buy recommendation!
