![]() None of these firmware versions is upgradeable to or from the other because of different controllers and/or RAM. I do install it once every 6 months or so to check for firmware updates. I have the same drive in a machine, and it runs great without it. ![]() I had no idea they had so many firmware versions for what is being sold under the same part number (I observed 3 firmware versions in a sample of 6 SU800-256 SSDs: R0247ANR, Q0922FS and R0247AC). 2 My suggestion: Install their software just for the purpose of checking to see if there is a firmware update for your SSD, then uninstall it. If I had to build this RAID array again, I wouldn't have chosen ADATA. ![]() ADATA says that running these two firmware versions in RAID is fine. I'm currently running four SU800-256 (Firmware R0427ANR) in RAID10 and keeping an additional SU800-256 (Firmware R0427AC) as a "hot" spare. CrystalDiskInfo is able to report SMART data for the individual drives even when they're in the RAID array, so diagnosing a failed drive is easy. ![]() These SU800s are TLC, so we're sacrificing reliability for cost. Replacement of the SSD was as simple as replacing the failed drive with the new drive and the RAID Array automatically rebuilt the replacement SSD. Fortunately, the RAID Array never skipped a beat and the system continued to operate without issues (despite the failing and eventually failed SSD).įor anyone who needs a reasonably high degree of reliability with the ADATA SU800-256 in a desktop or server, I would strongly recommend RAID. The new SU800 is error-free (so far) and RAID controller errors are back to 0. My Intel RAID controller did eventually mark this failing SSD as "Failed" (after less than 30 days of ownership) before I replaced it. I replaced the SU800 that was reporting an increasing number of "Reallocated Sectors Count" and "Reallocation Event Count" SMART errors. Knowing what I know now, I would not purchase ADATA SU800-256 SSDs for a RAID array (too many firmware versions for the same part number). Summary: My RAID10 array is running fine after replacing the failed SU800-256. Also, while modern operating systems and RAID drivers allow trim commands to run on SSDs in RAID, legacy operating systems and drivers may not properly support them, meaning functions such as Garbage Collection become more important for maintaining the highest performance from connected SSDs.Update after replacing the failing SU800-256 in my RAID10 Array For example, Crucial Storage Executive is not fully compatible with some RAID controllers and configurations, and specific functions such as SMART reporting or firmware updates may not work at all in these unsupported environments, requiring the RAID to be temporarily disassembled for updates or troubleshooting of individual drives. In terms of day-to-day use, RAID works similarly to a single disk, but diagnostic tools read data from a RAID configuration differently than they do a single SSD or hard drive. Refer to support for your motherboard, operating system, or dedicated RAID adapter for detailed instructions on setup and management. Steps to configure RAID vary depending on the exact type being set up, but generally an array is configured in a RAID adapter's firmware utility or your system's UEFI or BIOS, then an operating system looks at the array as a destination to partition and begin writing data to, either installing an operating system to the RAID or using it as a secondary volume. Software RAID is generally cheaper to configure and use, but investing in dedicated hardware to set up RAID reduces CPU and other system resource usage to manage the array. Hardware RAID uses a dedicated RAID controller to manage the installed drives and software RAID uses software within your installed operating system to do the same. The differences between these arrays are in how many disks are required and how they are used to boost performance while allowing for one or more drives to be lost before data loss occurs. Additional types exist when a combination of striping and mirroring are used, such as RAID 10, RAID 5, and RAID 6. RAID descriptions include a number as shorthand for what kind of operation the collection of disks is configured for, with a striped array being commonly referred to as RAID 0 and a mirrored array as RAID 1. Performance and capacity differences across connected drives reduce performance and usable capacity in every disk in the array to that of the lowest performing part. These arrays work best when all connected drives are identical, but in many RAID environments different disks can be used. They can also provide parallel operation so that read and write operations can be split across devices to increase performance as multiple disks can be used at once for a given operation (called "striping"). They can provide duplication of data so no files are lost in the event of a drive failure (called "mirroring"). RAID (Redundant Array of Independent Disks) configurations use multiple SSDs or hard drives.
