it is great replacement for the original SSD that comes with it.

The guy at Best Buy said it would cost $450 to do all of that with the preferred hardware replacement from HP, but getting this larger mSATA SSD was cheaper than the replacement 128GB SSD

Great replacement drive

but you needn't worry as it's right around its stated maximum speeds out of the box

Slid right into an Acer Aspire S7 and worked as it is supposed to.
