Reviews Word on the street for the Crucial Adrenaline

The big benefit of the Adrenaline is that you can use it with a standard mechanical hard drive without losing any of the data stored on it.

What People Are Saying Give it to me straight


This 50GB version can be found inline for right around $100 and though they don't officially list the read/write specs, it should be very close to that of the 64GB version of the m4 drive which is 500MB/s reads and 95MB/s writes and up to 45,000 IOPS reads and up to 20,000 IOPS writes.

You'll need the supplied license key to be able to download the software but the whole process is quick and painless.

It uses complex algorithms to determine which data is the most frequently access (i.e. boot files) and mirrors them on the SSD so that accessing that data loads much faster.
