HDD/SSD

This section allows you to monitor the status of the HDD/SSD installed on your DiskStation, providing options to manage and analyze HDD/SSD performance and health. Go to Storage Manager > HDD/SSD to manage these options.

To check HDD/SSD info:

Go to the HDD/SSD tab.
Select a drive from the list and expand it. Here you will see the S.M.A.R.T. status, volume info, model name, serial number, firmware version, and temperature.

To check health info:

Go to the HDD/SSD tab.
Select a drive.
Click Health Info.
Go to the Overview tab. Here you will find out how many hours the drive has been powered on, the current temperature, reconnection/re-identification count, bad sector count, and the overall S.M.A.R.T. status.
Go to the S.M.A.R.T. Info tab. The numbers listed can help you further diagnose the status of your drive.

Note:

SAS drives do not support S.M.A.R.T. info.

To start a S.M.A.R.T. test:

S.M.A.R.T. Test will examine and report the status of your drives, alerting you to possible drives failures. We recommended promptly changing your drives if any errors are detected.

Go to the HDD/SSD tab.
Select a drive.
Click S.M.A.R.T. Test.
Choose a test type and click Start to begin the test.
The latest test results are displayed in the Test Result section.

Note:

Test time varies depending on your system environment.

To schedule S.M.A.R.T. tests:

S.M.A.R.T. tests can be scheduled to run automatically by creating tasks.

Go to the Test Scheduler tab.
Click Create to set up a new task.
Modify the following settings on the General tab:

Task: Enter a name for the task.
S.M.A.R.T. Test Type: Choose to perform a quick test or extended test.
S.M.A.R.T. Test Range: Choose which HDD/SSD to test each time the S.M.A.R.T. test is performed.

On the Schedule tab, modify the following settings:

Date: Specify when to perform the S.M.A.R.T. test. S.M.A.R.T. tests can be scheduled to run on certain days of the week (e.g. daily, weekends, or every Sunday, etc.) or on specific dates (e.g. 2015/10/21).
Time: Specify how many times the S.M.A.R.T. test is performed, as well as the first and last time each day.

Click OK to finish.

To perform Secure Erase:

Go to the HDD/SSD tab.
Select a drive and click Secure Erase.

Note:

Secure Erase cannot be performed on drives in expansion units.
Secure Erase will permanently remove all the data stored on your drive. Please make sure the chosen drive is not in use or the data has been backed up before doing so.
When the system is performing Secure Erase, the chosen drive will be temporarily locked and then automatically unlocked when the operation is completed.
If Secure Erase is stopped improperly during the operation, you can re-execute Secure Erase directly on the user interface. If the drives are removed or used elsewhere when they are still being locked, please enter the password "synology" to unlock the drives.

Enabling Write Cache Support for HDD

Enabling write cache support enhances the performance of your DiskStation. Only certain HDD models support this feature. To ensure data protection while using write cache support, usage of a UPS device is strongly recommended. We also suggest the system be shut down properly every time after use. Disabling write cache will reduce the chances of data loss caused by abnormal power outages, but system performance will decline.

To enable write cache support:

Go to the Cache Management tab.
Tick Enable write cache. By default, this function is enabled.
Click Apply.
