OCZ Offering Important Firmware Update for ARC 100 and AMD Radeon R7 SSDs

On January 29th, OCZ released an important firmware update for their Arc 100 and OCZ-built AMD Radeon R7 SSDs. Kristian Vatto over at AnandTech was good enough to post a detailed recap of what this firmware update is all about. OCZ is listing this update as “mandatory for system stability.” Many firmware updates address more than one concern, and may also include improvements of existing features. This update is no exception, as it fixes the primary concern, as well as improved error handling and bad block management.

Under the existing firmware, the DRAM would go through a “training period” for DRAM timing calibration when the controller powered on. A DRAM refresh could occur during the duration of this power-on cycle, creating the potential for DRAM corruption that could compromise the SSD’s stability and reliability. The new firmware ensures that the DRAM refresh occurs outside of the controller power-on cycle. Thus far, only the 480GB versions of the ARC 100 and Radeon R7 have displayed this issue, but all ARC 100s and Radeon R7s should be updated as a precaution.

Just like any other data that is stored in NAND, the bad block list is vulnerable if a standard NAND failure occurs. This firmware update adds improvements to address the possibility of a NAND block(s) containing the bad block list failing and requiring the read-retry routine to trigger. As Kristian points out, this is more a theoretical “what if” situation, but it is always nice for users to see improvements to any aspect of their drives.

Neither of these secondary improvements are the result of addressing a problem, but again are a result of OCZ’s commitment to continuous improvement. OCZ will also be updating the Vertex 460A with the error handling improvement in the near future. As shown in the screenshot above, the firmware update is version 1.01, and you can download it from the OCZ website here.

An easy update for the Radeon R7. Thanks for the notification. I wonder why I did not get an update notification from OCZ/Radeon.

How do you update the firmware? I install the ocz R7 toolbox but it doesn’t recognize my 3 ssd’s in raid 0 so I separated them and still doesn’t recognize them. Windows recognizes them just fine thogh. What do I do?

Jeremy Poulin- I do not use RAID, so these are general recommendations. Check the Radeon Toolbox User Guide. It does not address RAID directly but there are a couple of things there that I might try. If that doesn’t help, contact Radeon customer.support directly. In fact, I might wait until Monday and contact them before trying anything else anyway. I have read some things about TRIM and RAID, and those issues may be involved in the firmware update and your difficulties. Radeon customer service should have the latest information on that. Jim
