Crucial m4 (256GB)


Though the 256GB Crucial m4 offers good performance in most situations, it's surpassed by competing drives from OCZ and Intel that push SSD technology a bit further.

Good performance. Supports 6Gbps SATA III.

Expensive. Outperformed in most tests by competing SSDs. Slow garbage collection demands TRIM support in OS.

Crucial M4 (256GB) Review and Ratings


On our benchmarks, Crucial's M4 drive was appreciably speedy, without ever breaking new ground. If you're looking for well-rounded performance, it's a solid choice, but a bit pricey.

Consistently fast performance on all of our benchmarks ; Doesn't lag far behind pricier drives ; Also available in 7mm versions for thin laptops

Accessories and software cost extra ; Pricey compared to several other performance-grade drives, which were faster on some benchmark tests

Few things are as simple as we'd like them to be, and measuring drive speed is certainly no exception. Most performance drives excel in one or two tests, and falter in other areas. OCZ's 256GB Vertex 4 drive, for example, is the fastest drive we've...

Crucial m4 256GB


SSD with high capacity and fast speeds at a competitive price.

As we've said before and we'll continue to hammer any chance we can get, the single biggest bottleneck in modern systems is the traditional plattered hard drive, and using an SSD in your system will make such a massive difference that you'll...

Crucial Ballistx 1600 Tracers -


When AMD released the HD5850 and the HD5870 end of September 2009 they had a clear plan on how they would bring DX11 to every possible price point. The HD5700 came out in October followed in November by the HD5970. These cards all fitted into various...

Crucial 128GB SSD


Crucial, a well established brand in the memory market has recently released a low-budget fast Solid-state Drive, the CT128M225. The drive uses a Indilinx Barefoot controller and a 64MB cache by Elpida Memory; a reliable configuration that we have...

We found the Crucial CT128M225 series blazing fast and highly responsive in all the tasks. The price may be somewhat higher than OCZ's solutions, but don't forget that Crucial is offering two extra years of warranty, which is very important....

Crucial 32GB Solid State Drive


Hard drives are constantly getting larger and cheaper as the technology improves, but their speed increases only marginally each year because they are limited by their inherent mechanical nature. No matter how efficient an algorithm or the overall...

The manufacturer’s website has a large selection of help and support options

This RAM upgrade has a higher latency than a few of the other products

We recommend Crucial memory upgrades because the manufacturer is reliable.

Crucial SSD 32GB


There's probably no better upgrade you can give your notebook than a solid-state hard drive. It will help your notebook run much cooler, with no noise...

No moving parts, runs cool and quiet

Expensive, small capacity, slow write speed

It's too early for solid-state drives such as Crucial's SSD 32GB to become mainstream, but once prices come down, evey laptop owner should look to upgrade to one. They are silent, run very cool and have no moving parts, which means that they won't be...
