Huge improvement over my laptop's HDD
By Bill E on Reviewed in the United States on August 7, 2017
I bought a new Asus Q524UQ laptop and was really struggling with how slow the included 2 TB 5400 RPM hard drive was. The computer took forever to start up and seemed particularly awful when it was attempting to install updates. I was glad to see there was an open M.2 slot in the computer and, as I'm sure many people viewing this item have, found that this was one of the cheapest options available. I decided to take a shot with it and am very pleased with the results. The installation of the drive could not be easier. The most difficult part really was remembering where I left the screwdriver I needed to open up my laptop, though that was more the fault of Asus for using a weird screw and me for not being very organized. Once I had it popped open installation of the drive took about 10 seconds. It pops right in the slot and then you have to screw it down. The one thing to keep in mind is that you will need to have your own screw. The drive doesn't come with one and in my case the laptop didn't have one preinstalled either. Fortunately I had one, but if you don't you will need to acquire it. I believe it's an M2x3mm screw. From there the slightly tricky part was moving the OS from the original HDD to the newly installed drive. There are actually two methods I used and both worked without much issue. The first option I tried was simply cloning the drive using Macrium Reflect software. The process was fairly easy and since it was a brand new laptop I just copied everything on the hard drive over, went into the BIOS, and changed the boot order. The difference was night and day. Booting from this drive took mere seconds compared to the rather lengthy process with the original drive. Although the clone option was easy, I ended up using a flash drive to do a complete reinstall of Windows 10. The main reason I switched to this was because the laptop came running an older version of the OS and it was easier to start fresh with the newest version one time than to keep going through the update process. This also wiped out all of the Asus preinstalled software that I didn't really want. If you have a computer you've been using and don't want to lose anything I'd recommend the clone option. For a newer laptop or just one that's full of bloat that you don't care about losing it's probably easier to start fresh with the flash drive installation.

Not the best for RAID; Watch for Reallocated Sector Errors (SMART Errors) and firmware versions
By Amazon Shopper on Reviewed in the United States on December 24, 2019
The ADATA SU800-256 is not be your best choice for RAID arrays and reliability may be an issue. Details below. I purchased five ADATA SU800-256 SSDs for a RAID-10 configuration (4 for the RAID array and a 5th SU800-256 as a backup). The first thing I noticed was that the SSDs had different firmware versions (I later learned from ADATA that this was due to different controllers and/or different RAM chip densities used in each SSD). ADATA Tech Support advised me to make sure the SU800s in my RAID array had the same controller. After getting 4 SSDs with same firmware (R0427ANR) and installing, I immediately noticed that one of the drives was reporting SMART events (Reallocated Sectors Count and Reallocation Event Count SMART events were both increasing regularly) while the other 3 SSDs had no Reallocated Sector events. My Intel RAID controller was also reporting a few "blocks with media errors" which I was able to temporarily able resolve by running Intel's Rapid Storage "Verify" a few times. I'm not sure if this is common manufacturer practice, but ADATA produces the SU800-256GB with potentially different controllers, potentially different RAM chips and potentially different firmware (varying between units with the same part number). If you are installing these SU800-256 SSDs in a RAID array, this makes maintenance difficult, because the ADATA firmware versions for the SAME SU800-256 part number are not compatible with each other and you won't be able to upgrade your SU800-256 SSDs with the same firmware (if your SSDs have different controllers and RAM chips). Amazon sells these SU800-256 SSDs (probably unknowingly) as identical units even though they are NOT identical. I RMA'd the failing SU800-256 and received a replacement from Amazon that had yet ANOTHER firmware version (because of different RAM chip densities). The 3 firmware versions that I have observed in my small sample of SU800-256 SSDs are R0427ANR, R0427AC and Q0922FS. These firmware versions are not compatible with each other and can't be upgraded from/to each other. This makes maintenance of multiple SU800-256 SSDs a real pain. Had I known this, I would not have purchased ADATA SU800-256 SSDs for my RAID array.
