Crucial is a new player on the SSD market but it has quickly gained significant exposure and following among computer enthusiasts. Their Crucial 128 GB m4 drive (model CT128M4SSD2) is a new contender on the 6Gbps 2.5 inch solid-state drives market and it’s getting rave reviews from the users. The m4 is an upgrade to the widely popular realssd c300 series.

Being a 2.5-inch drive, it’s designed to be primarily a laptop drive replacement though it will work equally good in a desktop setup (I use a 2.5-inch Vertex 2 in my desktop PC). According to the reviews, Crucial drives are really balanced in terms of speed and reliability, so if you’d like to dramatically speed up your system and not have to worry about the drive failing – Crucial 128 Gb m4 is the way to go.


Proud Brand Name

Crucial is part of Micron – a huge computer corporation specializing in memory, therefore all Crucial drives are created in-house. So these guys know a thing or two about flash memory and I would trust them to build a fast and reliable flash-based solid-state drive.


This drive was built to standard hard drive dimensions so it will be easy to swap your hard drive for this little monster (which has been confirmed by reviewers)

Most people use it to replace an old HDD in their laptops – Dell’s, Toshiba’s and Apple MacBook Pro’s. One thing everyone notices about this drive is how FAST their laptops became. A couple of reviewers mentioned they’ve installed Crucial 128GB m4 into their old machines and couldn’t help thinking they’ve got a brand new laptop – the boot time and applications launch times were cut in more than half. One review even posted a table comparing his boot times with a not-so-slow hard drive and this new SSD – on average he got a whopping 650% increase in boot-up time!

Another good thing about drive is that it’s an easy replacement for almost every laptop – this was noted by many users. There’s no messing around trying to fit this guy in – you just slid it snugly in, close the cover and you’re ready to rock.

Few people have also noticed an increase in battery life – their laptops now run longer on a single charge. And of course as with all SSDs this Crucial 128GB m4 SSD runs completely silent and very cool.

The best thing is the price – Crucial’s SSD is quite a bit cheaper than it’s Intel’s and OCZ’s counterparts.

Overall, I would recommend this drive as a perfect laptop drive replacement coming from a serious manufacturer that will speed up your notebook and has enough space for your OS and apps.
