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.

So, have we seen a repeat performance of the RealSSD C300's grand entrance? Not really. Although we found the m4 to be considerably faster in our file transfer tests as Crucial fine-tuned top end sequential performance, that had little impact on our...

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....

It is really hard to find any problems with Marvell 88SS9174 controller, which is used in the solid state drives reviewed today. Its characteristics and internal architecture allow designing SSDs with up-to-date performance, and such SSD makers as...

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...

After Valentine's Day, SSDs prices fell yet again, and we updated our list to reflect those changes. This month, the best deals are found in the mid-range offering, and there's one bargain in our list for a 240GB SSD that you simply will not...

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...

The great thing about revisiting the Crucial m4 is that we now have a great deal of experience with these drives. When I first looked at the m4 back in May of 2011 some 9 months ago a lot was unknown about the product, most importantly reliability. It...

The year 2011 was quite complex in SSD matters. The industry finally made a move towards SATA3 (6 Gbps) and with that arrived a lot of new controllers and thus SSDs. Earlier in the year the most promising SSDs where based on SandForce 2281...

The performance of the m4 is rather interesting. The drive's random write speed is able to compete against SandForce drives but its random read speed falls behind the competitor. Its sequential read is faster and competitive yet the sequential write...

Looking through the benchmarks, at times our setups do become a bit wobbly, especially the older C300 one. For the most part, though, we can see performance is extremely strong on the new m4 setup with some of the best gains being shown under HD...

The Crucial m4 is an interesting SSD. It is the highest performing drive we have tested that doesn't rely on real-time file compression to achieve high levels of performance. Or to put it another way, there's only two other SSDs that can deliver...

Welcome to the sixth iteration of our highest-ranked SSDs at any given price point. We updated our recommendations to reflect the recent price drops on second-gen SandForce hardware. There are several good deals to be found for right about £150....

As we have seen from the documentation on the Internet and from the test results, the previously reviewed SSD had a SandForce processor in it, which relies on compression techniques and the performance of the drive varies, depending if the data...

So after reading all the results i am sure many of you are wondering about which SSD is currently the best one in the market. Well if you can afford the extra premium then the RevoDrive3 240GB is without doubt faster than every other SSD in...

Crucial has a real winner on its hands with the m4; this latest firmware 0009 bumps the performance up a notch and, combined with the company’s aggressive pricing, makes it one of the better choices for a modern SATA III SSD. We observed read...
