Hard Disk Sentinel monitors HDD and SSD health, temperature, and performance through drive status and S.M.A.R.T. data. It runs in the background and can alert you when it detects an error or unexpected behavior.
What drive information does Hard Disk Sentinel show?
The program presents health and performance readings for HDDs, SSDs, and hybrid drives. S.M.A.R.T. monitoring supplies the status and attribute data it uses to flag problems, while temperature readings show current conditions and retain maximum and average values. Those temperature records can show how a drive behaves under heavier use.
Hard Disk Sentinel also measures transfer speed in real time. Changes in speed alongside health or S.M.A.R.T. readings can help identify performance degradation. Its reports and textual descriptions provide details about detected drive conditions and tips related to them.
Which drives can it monitor?
Hard Disk Sentinel can inspect internal disks and drives attached through external enclosures, including USB and e-SATA storage. Its supported drive types include HDDs, SSDs, SSHDs, NVMe SSDs, and disks in RAID arrays. It can also monitor NAS drives.
- View health, temperature, and S.M.A.R.T. information for monitored disks.
- Use live transfer-speed measurements to observe disk performance.
- Receive warnings when the program finds an error or unexpected drive behavior.
How do alerts and background monitoring work?
After starting, Hard Disk Sentinel monitors drive status in the background. If it detects an error or unusual behavior, it warns about the current condition. This lets you investigate a change while the drive is still accessible and decide whether to protect important files or look into the hardware.
The program can provide alerts and reports for disk monitoring. Its Professional edition adds scheduled and automatic backup options that can start when a problem occurs; those backup features are separate from the health and temperature monitoring described above.
Pros
- Tracks S.M.A.R.T. values alongside drive health and performance
- Records current, maximum, and average temperatures
- Measures disk transfer speed in real time
- Monitors drives in RAID arrays and external enclosures
Cons
- Scheduled and automatic disk backups require the Professional edition

Does Hard Disk Sentinel monitor SSDs as well as hard drives?
Yes. It monitors HDDs, SSDs, hybrid drives, and NVMe SSDs, including health, temperature, and S.M.A.R.T. data.
Can it monitor a drive connected through USB?
Yes. It can monitor drives in external enclosures, including USB and e-SATA connections.
What does a transfer-speed reading tell me?
Hard Disk Sentinel measures disk transfer speed in real time. The readings can show performance changes alongside health and S.M.A.R.T. information.
