4TB Synology Plus (HAT3300-4T) Hard Disk Drive Review!

4TB Synology Plus HDD Features + Temps!

4TB Synology Plus HDD Key Features!

The 4TB Synology Plus (HAT3300-4T) hard disk drive is designed for the light-to-intermediate usage requirements of personal and SMB (small and medium business) NAS systems. Here are its key features:

Manufactured By Seagate

Synology does not make this hard disk drive, which was manufactured by Seagate. Think of this as a Seagate IronWolf hard disk drive that was customised to Synology’s requirements, and with custom firmware for Synology.

Under The PCB

In the following video, we took a look under its PCB, and here was what we found:

The 4TB Synology Plus (HAT3300-4T) comes with a large 256 MB SDRAM cache, courtesy of a Samsung K4B2G1646F memory chip. This is a DDR3-1866 SDRAM chip with 16 memory banks, and a peak transfer rate of about 466 MB/s.

It also uses a Seagate Dillon motor drive controller, which features ST Microelectronics’ proprietary Smooth Drive pseudo-sinusoidal digital drive technology. The drive controller itself has a thermal pad to help keep cool, by transferring heat to the drive chassis.

Finally, this NAS drive has two sensors on its PCB, which allow it to better detect shock and vibration events, and dynamically adjust the flying height of the read/write heads to avoid head crashes.

Always-On Operation

The 4TB Synology Plus is backed by a million hour MTBF (Mean Time Before Failure) rating, and is rated for a workload of 180 TB per year.

That works out to 15 terabytes per month, and is about par for the course for consumer-grade NAS drives.

Easy Firmware Updates

Unlike third-party NAS drives from Western Digital or Seagate, you can easily update the firmware of the 4TB Synology Plus hard disk drive using DiskStation Manager (DSM) in Synology NAS systems.

This is a convenient feature for those who use Synology NAS systems – you won’t need to remove the drive, or use a separate computer, to update its firmware.

Low Power Consumption

Power consumption is pretty low, at just under 5 watts. Even if you run this drive 24/7, it will only consume 42.5 kW per year.

Real world usage will be significantly lower, since NAS systems are designed to power down drives during periods of inactivity.


4TB Synology Plus Operating Temperature

We monitored the surface temperature of the three hard disk drives while idle, and during their benchmarks. The following chart shows their operating temperature range, from idle to maximum load.

Please note that instead of giving you the absolute numbers, we are showing the temperature delta, which is the difference between the actual temperature and the ambient room temperature.

The 4TB Synology Plus (HAT3300-4T) appears to run slightly hotter than the 4TB WD Red, but significantly cooler than the 6TB WD Red. This is good news, because it can get really hot inside the NAS enclosure!
