Crucial M4 256GB Solid State Drive Review

The Crucial M4 solid state drive was one of the most popular and most successful solid state drives of 2011.  Much of that success can be attributed to Crucial’s reputation for reliable, quality-made products and because they are one of the largest memory producers out there.  When the M4 first came out it only had a rated read speed of 415MB/s, which is pretty far off from what we’ve seen from other solid state drives in 2011.  Towards the end of 2011 Crucial released a firmware upgrade that boosted the rated speeds to 500MB/s read and 260MB/s write.  A nice improvement!  So today we have the M4 in our labs and we will be taking it through the paces.

Special thanks to Crucial for providing us with the M4 256GB Solid State Drive to review.

The M4 drive comes in a pretty plain box.  It does let us know that it is the M4 solid state drive and it is the 256GB version.  On the back it gives you a little bit more information on the drive.
