Final Words

The 0009 firmware update for Crucial's m4 drive mostly improves its sequential read performance. Unless you're doing a lot of large file copies to another high speed SSD or drive array you likely won't see any huge gains in real world use. Where does the m4 stand in the grand scheme of things? It is among the SF-2281 and Intel SSD 510s of the world when it comes to performance. The latter two generally benchmark better but all three drives do well in real world usage.

SSD Pricing
  Crucial m4 Intel SSD 510 Kingston HyperX OCZ Vertex 3
256GB/250GB/240GB $390.99

$569.49

$504.99 $489.99
128GB/120GB $227.99 $276.99 $244.99 $219.99

At $390.99 the m4 is one of the most affordable 256GB drives on the market today. You don't get the best absolute performance in all of our tests but you'd be hard pressed to tell the difference. The m4 does quite well in our light workload which is very representative of a typical desktop usage experience. My only concern with the m4 is really how bad the controller will let performance get with sustained random writes. I'd gladly trade lower 4KB random write performance for better sustained numbers.

If you don't want a SandForce drive and want something more affordable than Intel's SSD 510, the m4 just started looking a lot better.

    You self have recommended and the Intel SSD 320 have gain a lot of credit for it's reliability. Since this is debated i think you leave out Intels complete SSD disk is bad... and give the performance a to important role. No disk is useful if you loose the data on it...

    You to help me with
    I bought Crucial SSD SSD 512 GB M4, yesterday is still attached to the SERVER received, read, save data normally but today it does not grease the machine up to store data, not to delete data. The way you see the fix on my answer helps, thank you.

    You can now get a 256gb Crucial M4 for 289.00 on Amazon, and the prices will drip fuether when OCZ releases their new Vertex 4.
