Crucial M4

6/30/2012 6:00:31 PM

Available in sizes of 64GB, 128GB, 256GB and 512GB, the Crucial M4 is competitively priced throughout its line, but this manifests itself most readily at the lower prices. In particular, the 128GB version allows budget buyers to get more space at a lower cost than almost any other drive we've reviewed.

Description: Crucial M4

Although Crucial's larger M4 drives have been criticised for slow performance, the 128GB model is comfortably speedy in terms of real-world performance. It doesn't match up to the best -the Kingston HyperX 3K is faster - but it's close to being as good, and manages to hold up while being a much better purchase in price terms as well. It's been a while since Crucial's drives were the fastest, but they aren't out of the race, even if they don't quite match up to SandForce-based models.

As we've seen elsewhere in this guide, the low price isn't everything it seems, however. If you're aiming to put this in a desktop machine, you'll most likely need to buy a bay converter separately, which adds some expense onto the price. It's also inconvenient if you don't notice until you come to install the drive.

That said, its power consumption levels are rock-bottom, suggesting that it's really aimed at mobile, battery-powered computing so in some ways you can see why Crucial might not be eager to promote the desktop suitability of the product.

The one area you can truly say that the Crucial M4 fails, though, is in offering a substantial upgrade to current customers. If you already own a Crucial C300, you'll find that the M4 costs proportionally more while offering no significant performance improvement. Rather than improving its drives, Crucial shifted its priorities, coming up with something that performed well for a wider variety of typical uses, rather than aiming to have the fastest model on the market in theoretical terms.

Still, it performs quite well, and the low price for 128GB makes it a drive you should definitely look at, especially if you don't want to spend a lot of money.
