Crucial m4 (512GB)


Sharing the same design and interface as most of the other solid-state drives we've reviewed, the Crucial m4 stands out where it matters most: the price. It's still much more expensive than a traditional hard drive, but the m4 is the most affordable...

The Crucial m4 solid-state drive is competitively priced and offers fast performance. The drive supports SATA 6Gbps and works in all SATA-based storage applications.

The Crucial m4's performance could be better comparatively, and it doesn't come with a drive-bay converter to work with desktop computers.

So far, the Crucial m4 offers the best value among SSDs. Though it's not the fastest, it's by far the most affordable among its peers.

Crucial m4 (256GB)


Otherwise, the m4 came in third more frequently than it came in second—though it routinely surpassed the Intel drive (often by a large margin) in heavier-duty tests, such as the AS SSD Benchmark 4KB test at a queue depth of 32 (158.59MBps for read and...

Good performance. Supports 6Gbps SATA III

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

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.

Crucial M4 (256GB)


If you've ever looked into upgrading the RAM in your PC, there's a good chance you're familiar with the name Crucial. The brand, owned by Boise, Idaho-based Micron Technology, has a long history in the memory business. Plus, parent company Micron, in a...

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

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.

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 M4 256GB review


Is this Marvell based SSD too much money?

Latest 25nm NAND memory ; 6Gbps SATA support

SandForce drives are usually quicker ; Too expensive compared to others
