Took my laptop from a 160 second boot down to about 7 seconds. Had it for a few months, still works beautifully.

... Boot drive for early 11' mbp so far so good things are much smoother and quicker than the sshd
Using as boot drive for early 11' mbp so far so good things are much smoother and quicker than the sshd.Update: have since moved this to the optical drive spot via caddy setup now mac boasts ca. 1tb ssd storage and it is not bad for almost 10yrs old. Boot is quick with samsung pro and the adata now handles all downloads, drafts and anything else not wanted on the drive with the os.

I love this drive
I love this drive. The speed and performance increase in my pc was insane. If you don't have a ssd yet you are really missing out, and this is a excellent drive to go to.

Liked the capacity and price... But getting a high-pitched squeal from my corsair cx750m when it runs... My other ssd doesn't cause the noise...

Used in a build for my mother in law, and the ssd works perfectly, delivering high performance and silent operation (which she enjoy vs her old spindle hdds). Buy it if you want a very noticeable update from slower older hard drives with platters.
