Got a question about why your external SSD is slow to eject from your Mac? Learn why Mac takes so long to eject SSD and what we can do!
We were using an SSD to back up our data and tried to eject our external SSD on the Mac, but we found ourselves waiting a bit too long. This made us wonder if the delay was just us or if others experienced the same. We searched online and discovered that many Mac users face delays when trying to safely eject their SSD. Leading to the frustrating question: Why does Mac eject SSD slow?. After further research, we found the answer lies in a few technical details about how your Mac handles data transfers and writes to the SSD.
In this post, we’ll share our findings and explain why this happens, based on our research into how our Mac handles data transfers and writes to the SSD.
The Role of Write Caching in Slow Ejection
One of the key reasons why Mac eject SSD slow is the way macOS handles write caching. When you transfer files to an external SSD, macOS doesn’t immediately write them to the drive. Instead, it writes the files to a cache first, which is essentially a temporary storage area. Afterward, macOS continues writing those files to the drive in the background.
This process is designed to speed things up because it makes the system appear faster, as the file transfer seems complete when it’s actually still going on in the background. If you’ve ever noticed that little LED light flashing on an external SSD even after you think a transfer is finished. That’s the drive catching up to the cache.
Now, the problem arises when you try to eject the SSD while macOS is still working through the cache. If you pull the SSD too early, it can lead to data corruption or an incomplete file transfer. This is one of the main reasons why Mac eject SSD slow—it’s making sure everything is safely written to the disk.
How Mac Differs from Windows in Handling Write Cache
Interestingly, Windows and Mac differ in their approach to write caching. Around the time of Windows XP, Windows disabled the write cache on external drives for security purposes. This means, windows writes the data to the external drive almost immediately after a file transfer, minimizing the need for background processes that could delay ejection.
On the other hand, macOS keeps the write cache enabled on external SSDs. Which allows for faster file transfers and makes everything feel snappier. However, this also means that there’s a risk: the data might not have finished writing to the drive when you try to eject it. If you pull out your SSD without safely ejecting it. The system could have left some data in the cache, which could cause corruption or a broken file system.
Safe Ejection: Why It Takes Time
Now you may be asking, “Why can’t I just unplug the SSD and be done with it?”. Well, macOS is doing its best to make sure you don’t lose data. The safe ejection process tells your Mac to flush the cache to the SSD, making sure everything is properly written and stored before you disconnect it. This process ensures that no data is lost and the file system remains intact.
However, this can take time, especially if you’ve recently transferred a lot of files. The more data in the cache, the longer it takes to finish the process. This is why you might see the Mac eject SSD slow warning when trying to disconnect.
Why You Should Never Skip Safe Ejection
The whole point of safe ejection is to avoid potential data loss or file system corruption. If you just pull out the SSD without waiting for the process to complete. Then yo may you risk interrupting a write operation, which could lead to damaged files or even an unusable drive. So, when your Mac is taking a bit longer to eject the SSD, it’s actually ensuring that all your files are safely transferred, and your SSD remains in good health.
Also, if your Mac shuts down unexpectedly—whether due to a power outage or a force restart—it may initiate a file system check when it boots up. This process is another way to make sure that no files were lost due to improper ejection. If you’ve ever seen the file system repair progress bar after a sudden shutdown. That’s your Mac double-checking the integrity of the drive.
What You Can Do to Speed Up the Ejection Process
While safe ejection is important, there are a few things you can do to make sure Mac eject SSD slow becomes a rare occurrence:
- Close All Apps and Background Processes: Before ejecting your SSD, make sure no apps or processes are accessing the drive. This includes things like Time Machine backups, file transfers, or Finder windows that may still be using the drive.
- Give It a Little Time: Don’t be in too much of a rush. Even if you think the file transfer is complete, macOS might still be writing data in the background. Wait for the full process completion before you eject the drive.
- Check SSD Health: If your SSD is older or has some issues, it may take longer for macOS to finish writing to the drive. Using tools like Disk Utility can help you check the health of your drive. Also fix any problems that might be contributing to slow ejection.
- Avoid Unnecessary External Connections: If possible, connect your external SSD directly to your Mac, rather than through a USB hub or adapter. Sometimes using additional equipment can slow down the data transfer and the ejection process.
Conclusion: Patience and Safe Ejection Are Key
So, the next time you find yourself wondering, “Why does Mac eject SSD slow?”. Remember that it’s a safety feature design for data protection. macOS is ensuring that everything is properly written to the drive before allowing you to unplug it. While this may cause a bit of a delay, it’s well worth the wait to prevent file corruption or data loss.
So, the next time your Mac takes a little extra time to eject an SSD, take a breath, give it a minute, and let it do its thing. After all, a few moments of patience can save you from much bigger headaches down the road!
