Crucial m4 SSD Conclusion

Iometer IOPS Performance

Iometer is an I/O subsystem measurement and characterization tool for single and clustered systems. Iometer does for a computer's I/O subsystem what a dynamometer does for an engine: it measures performance under a controlled load. Iometer was originally developed by the Intel Corporation and formerly known as "Galileo". Intel has discontinued work on Iometer, and has gifted it to the Open Source Development Lab (OSDL). There is currently a new version of Iometer in beta form, which adds several new test dimensions for SSDs.

Iometer is both a workload generator (that is, it performs I/O operations in order to stress the system) and a measurement tool (that is, it examines and records the performance of its I/O operations and their impact on the system). It can be configured to emulate the disk or network I/O load of any program or benchmark, or can be used to generate entirely synthetic I/O loads. It can generate and measure loads on single or multiple (networked) systems.

To measure random I/O response time as well as total I/O's per second, Iometer is set to use 4KB file size chunks over a 100% random sequential distribution at a queue depth of 32 outstanding I/O's per target. The tests are given a 50% read and 50% write distribution. While this pattern may not match traditional 'server' or 'workstation' profiles, it illustrates a single point of reference relative to our product field.

The chart below illustrates combined random read and write IOPS over a 120-second Iometer test phase, where highest I/O total is preferred:

In our Iometer tests, which use 32 outstanding I/O's per target and a random 50/50 read/write distribution, SandForce SSDs clearly outperform the competition when tested which a larger queue depth. The PCI-Express based SandForce-driven RevoDrive SSDs lead the pack, followed by their latest SATA 6Gb/s storage solutions. The OCZ Vertex 3 peaks at 57553, and delivers the fastest IOPS performance we've measured on any SATA-based SSD. Crucial's m4 SSD produced 28826 IOPS in this particular test, leaving us to wonder what happened to the 90K it was suggested to produce. We dive into that topic later into this article, in the section named Proving Manufacturer Tests.

In our next section, we test linear read and write bandwidth performance and compare its speed against several other top storage products using EVEREST Disk Benchmark. Benchmark Reviews feels that linear tests are excellent for rating SSDs, however HDDs are put at a disadvantage with these tests whenever capacity is high.

Good review, Olin; thanks for your efforts.

I saw no mention of any built-in encryption tools. Not on-board?

But did note that the pricing as listed seems relatively consistent with SATA 3Gb SSD offerings, so it looks like the 25nm design is showing it's production benefits if nothing else.

# Price still an IssueEnigma8750 CMSSC Supreme Commander 2011-04-22 10:49
Unimpressive for me is all about the astronomical Price, as you mentioned in your Cons. Its really good that the Pharmacutical industry is not Manufacturing these things or we would be paying 20,000 dollar for ever hundred Gig.

Your Quote still gives me Sticker Shock, even though I can remember when VCRs were 1200.00 and a really good CD Player Was in Audiophile Magazine was $10,000.00 and my North Dakota, Gateway PIII 500 mhz was almost 2000.00, for the entire system.

"Micron will officially launch the Crucial m4 SSD on 26 April 2011, roughly one week from now. They current product pricing is as follows: 64GB Model $130, 128GB Model $250, 256GB Model $500, 512GB Model $1000. As soon as these SSDs reach retail shelves, we'll update this article with links to their online prices"

I personally would love the 256GB Model but "$500 dollars"? That is 70 to 80 percent of todays total build cost, without Mouse, Keyboard, Sound System and Monitor which I usually buy as I go, since I have most of those already.

Since the Speed of a System is also always equal to Weakest Link in the Chain having one of these Ferrari's in your system is a real boost to the system, but then you have to contend with the RAM only being able to deal with so much bandwidth or the processor is bottle necked because of a 1000 processes in the background or even worse the time it takes for the software to do its job can still bog a system down. I have a feeling that MS Windows 7 64 bit SP 1 would still take its time loading since it is loading so many files that the CIA could not handle it all.

Suffice to say, I want one of these Crucial or OCZ Drive, but when they get down in the Mid 2 hundred dollar level for 256 Gb if I have not died from old age by then.

qd 32...seriously, that's the best you could do

Yes, , QD 32 is the 'best we could do', because that's as high as the settings on these benchmarks will allow.

What's with the trolls these days? They can't piece together a proper sentence, but they can complain about the color of money.

Awesome review, Olin. It was very informative because I was looking to compare my C300 64Gb that I recently purchased to the newer gen Crucials. Smooth move with Dave's email address; #s will always be #s. People these days aren't appreciative of the hard work and effort it takes to do something like this. Ingrates.
