The RealSSD C400 represents a mild performance gain over last year's C300 during light workloads, it's handily dispatched by competing drives from OCZ and Intel when it comes to heavy multitasking, but that's okay if the C400's price reflects its inferior performance and it does -- there's nothing wrong with delivering an entry-level product.
Does not rely on realtime file compression to achieve highest levels of performance.
3 year warranty.
Available in up to 512GB capacities.
Rugged metal case.
Great random access speeds; 400MB/s reads, 250MB/s writes.
Not as fast as SandForce drives.
Performance could be better comparatively.
Doesn't come with a drive-bay converter to work with desktop computers.
Outperformed in most tests by competing SSDs.
Slow garbage collection demands TRIM support in OS.

Nothing gets my cooling fans going like a new hard drive! With that, I have yet to hop on the SSD wagon, until now. I have resisted as long as possible because even though the benchmarks were there, the prices just were not. Crucial thinks they can...

s I really liked the 128GB Crucial m4 when I first looked at it months ago. That was before the performance was significantly boosted by firmware upgrades, and without the benefit of a full stack of flash channels to utilize. Now we are looking at the...

Crucial is a name we always know for reliability and quality-made products and the M4 drive is no exception. It is very well made and besides the controller everything else inside is made by Crucial (Micron). Crucial does offer their standard 3 year...

The arrival of affordable, high-performance client SSDs gave us two (closely related) things: 1) a high-speed primary storage option that could work in both a notebook or a desktop, and 2) independence from traditional hard drive form factors....

There are more SSD disks on the market; for example: OCZ, Corsair, and a few others. Both Kingston and Crucial are big sellers though and perform very well in most tests. The Patriot drive in this test was older but managed to keep up very well with...

Performance of the Crucial m4 SSD when paired up in RAID0 was impressive, especially in areas with heavy read activity. In straight line performance the m4 in RAID0 measured 878MB/s read and 524MB/s write, more than doubling the previous write...
