Detailed Description

We have introduced a solution that addresses some concerns on the high write amplification on the Intel® SSD 530 Series and the Intel® SSD 535 Series products.

Follow the steps below to update your Intel® SSD with the solution firmware. For more details on write amplification and the concerns addressed, see the messaging below.


Update your Intel® SSD with the solution firmware

Note: If you are concerned about the amount of write amplifications while using Intel® SSD 530 Series and the Intel® SSD 535 Series products, use the tool below to change your device's firmware.


The following steps detail how to utilize the iRMFUU.exe to change the firmware for:

  • Intel® SSD 530 Series drive to firmware version

    • M.2 to DCV1
    • 2.5” to DCV2
    • mSATA to DCV3

  • Intel® SSD 535 Series drive to firmware version

    • 2.5” 56GB to ZG2V
    • 2.5” other to RG2V
    • M.2 to RG1V


  • Before initiating the iRMFUU, read all the instructions below. The firmware update process is done entirely at your own risk.
  • Before attempting the firmware update, back up or make copies of your files. If the Intel® SSD firmware update process is interrupted, your Intel® SSD may not function properly.
  • On RedHat 7.1, command “modprobe –sg” must be executed before running iRMFUU. Otherwise the tool won’t detect/enumerate any drives.
  • If you purchased your Intel® SSD from an OEM, your firmware version may have a different naming. Contact your local OEM representative for latest firmware revisions.
  • The utility is only supported on Windows* operating systems. If you are experiencing issues with updating your firmware on non-Windows OS, contact Intel Customer Support


Process steps

  1. Download the iRMFUU package.
  2. Copy/Unzip files to the root directory (for example, C:\\). This creates an “iRMFUU” directory.
  3. Open Command Prompt as Admin.

    • On Windows 7*

      • Click Start > All Programs, and then click Accessories.
      • Right-click Command prompt, and then click Run as Administrator.
      • If the User Account Control dialog box appears, confirm that the desired action is displayed, and then click Continue.

    • On Windows 8.1* and Windows® 10

      • Right-click the “Window” icon at the bottom left of your screen or press Windows + X on your keyboard.
      • Select Command prompt (Admin).
      • If the User Account Control dialog box appears, confirm that the desired action is displayed, and then click Continue.

  1. Change the directory to :\\iRMFUU (for example, cd c:\\iRMFUU).
  2. Run the tool executable irmfuu_7.0.1.exe.

    • Tool will detect all supported drives related to this process and automatically perform the update.
    • When the process is complete you should see a “Status: Firmware Updated Successfully. Please reboot the system.” message.

  3. To verify the new firmware on your drive, run the tool executable with the following arguments: 0.1.exe show -intelssd


Write Amplification

Write amplification is the difference between host writes and NAND writes. There has been concern over the amount of write amplification while using the Intel® SSD 530 Series and the Intel® SSD 535 Series. Some users have noted that the write amplification on the Intel® SSD 520 Series was much lower.

The Intel® SSD 530 Series and Intel® SSD 535 Series added architectural changes around power savings with low-power states, which changed the drive behavior compared to predecessors in this same product line. Low-power state support requires the drive to perform bookkeeping activity in the background for data loss protection and faster resume from low-power states. This adds a factor to the write amplification. For example, a small quantity of host writes accompanied by low-power state transition, the write amplification will be due to the writes performed by the background bookkeeping plus the host writes. On some systems, this may have write amplification impacts. However, the drive was also built to meet the same reliability and endurance standards as the Intel® SSD 520 Series.

Some write amplification are expected. Because of the NAND architecture, while other drive activity is occurring, the drive performs garbage collection by moving “in use” data to new areas and reclaiming deleted blocks as free space. The amount of write amplification depends on the type of writes and amount of deleted data. Certain workloads can trigger a higher write amplification. For example, small file size write operations over long periods of time can generate more garbage collection than large file size write operations.

The power saving modes in the Intel® SSD 530 Series and Intel® SSD 535 Series products can also add extra background write operations before taking the drive into a lower power state. If the drive transitions into lower power and then wakes up often, the number of background operations can increase. In effect, write amplification increases. Standard user activity is typically a mix of write behavior (not only small IOs) with power-saving transitions spread out over time.

If your typical activity is not approaching the endurance rating as specified in the product specification, there should be no excessive wear out on the Intel® SSD. If you have any concern about wear out, monitor the SMART attribute E9h. We warranty the Intel SSD based on your adherence to usage as stated in the product specification.

High write amplification is typically observed when there are fewer host writes and/or the drive goes through many idle cycles with no host activity. Bookkeeping tasks to preserve the drive’s state during idle time result in a higher write amplification.

We have introduced a solution that addresses the high write amplification concern of some customers. You may see some impact to battery life based on usage behavior.
