Common Issues

The Samsung MZ-77E4T0 870 EVO 4TB Internal SSD is a high-performance storage solution, but like all hardware, it can encounter certain issues. Here are some common problems users might experience:

1. Compatibility Issues:

   • Cause: Not all systems, especially older ones, support the SATA III interface or the large 4TB capacity.
   • Effect: The SSD might not be recognized by the system, or it may operate at reduced speeds if the system only supports SATA II.

2. Firmware Bugs:

   • Cause: Bugs in the SSD’s firmware can cause instability or performance issues.
   • Effect: Users might experience slowdowns, data corruption, or the drive not being recognized. Firmware updates are often needed to resolve these issues.

3. Performance Degradation Over Time:

   • Cause: Continuous write operations and the nature of NAND flash memory can lead to performance degradation.
   • Effect: Users might notice slower write speeds and increased latency after prolonged use.

4. Overheating:

   • Cause: Extended use, especially under heavy workloads, can cause the SSD to heat up.
   • Effect: Thermal throttling might occur, reducing performance to prevent damage, or in extreme cases, the SSD might fail.

5. Power Loss Protection:

   • Cause: Unexpected power outages or improper shutdowns.
   • Effect: Potential data loss or corruption, as consumer-grade SSDs like the 870 EVO do not have robust power loss protection compared to enterprise-grade models.

6. Sudden Failure:

   • Cause: Manufacturing defects or electronic failures.
   • Effect: The SSD might suddenly stop working, leading to potential data loss and the need for replacement.

7. Wear Leveling and Endurance:

   • Cause: Despite having a high endurance rating, intensive write workloads can wear out the NAND cells over time.
   • Effect: Reduced lifespan and eventual failure if the drive’s endurance is exceeded.

8. TRIM Command Issues:

   • Cause: Some operating systems or configurations may not properly support the TRIM command.
   • Effect: Without TRIM, the SSD might experience slower performance and reduced lifespan due to inefficient data management.

9. Data Migration Problems:

   • Cause: Cloning software or migration tools might not always work seamlessly.
   • Effect: Users may encounter issues when transferring data from an old drive to the new SSD, such as incomplete data transfer or boot problems.

10. Firmware Updates:

    • Cause: Updating firmware can sometimes be problematic if not done correctly.
    • Effect: Failed updates can lead to drive instability or even render the SSD unusable

870EVO SSD formatted and reported as unallocated data recovery case log

02Aug24: A customer came in with this Samsung SSD formatted for a linux system. Using our ubuntu server software we are able to recover the files to another Linux formatted SSD.

870EVO 4TB Samsung MZ-77E4T0 not detected data recovery case log

08Jan25: This SSD does not show any activity at all and suddenly stopped working as reported by the customer. The drive was drawing 0.1 watts on a steady state and no fluctuations. There was a burnt out hole in the e-fuse chip AtGFD and the output side was shorted to ground. You can see this chip in the top left corner of the photo.
