The firmware updater can process multiple M4s at once, and from our experience, doesn't reformat or damage any files on the drive (although you should still backup irreplaceable files before updating regardless). The flashing process takes a few minutes (we found it was much longer when flashing the larger 256GB version), and flashes any retail M4 SSD to the latest 0009 firmware. You’ll also need to move your SSD port 0, 1, 2 or 3 on the motherboard, and set the SATA configuration from AHCI to IDE, before booting from the disc. With the latest 0009 firmware release, Crucial has announced a significant uptick in data throughput, as well as reduced write latencies.Ĭan the Crucial M4's new 0009 firmware reel in the awesomeĬrucial M4 Firmware DeploymentCrucial’s latest firmware is available as an ISO file, which can be burnt to a CD or DVD via Windows 7’s integrated Disc Image Burner. Remember that companies using Marvell SSD controllers need to write the firmware themselves, while SandForce supplies firmware with its controller chips. We found SandForce drives, even when handling incompressible data, were capable of read speeds in excess of 515MB/sec, while Crucial and Intel’s SATA 6Gbps drives languished with sequential read speeds of around 435MB/sec.Īt the time we presumed this was due to the use of the Marvell drive controller, but it looks as though the lower write speeds were simply a result of Crucial still getting to grips with the controller. However, despite most drives using similar 25nm NAND, be it Intel or Micron in origin, the performance of the drives were very different. Crucial M4 vs OCZ Vertex 3: New Firmware Face-OffEarlier this year the second round of SATA 6Gbps SSDs arrived, first in the form of Marvell-controlled drives such as the Crucial M4 256GB and Intel 510 series, and then with SandForce 2281-based drives such as the OCZ Vertex 3 240GB and Patriot Wildfire 120GB.
