| RPM | 7200 |
| Interface | SATA 6Gb/s |
| Cache | 512MB |
| Warranty | 5 Years |
The Western Digital Red Pro 20TB is the gold standard for anyone running a business-grade DS923+ setup. During my testing, I found its vibration control to be superior to any other drive in this class, which is vital when you have four of these spinning in such close quarters. Whether I was hosting multiple Docker containers or managing high-bitrate video editing projects directly from the NAS, the sustained throughput never dipped significantly. In a 24/7 environment, the mechanical reliability here is unmatched, giving me genuine peace of mind regarding data integrity. It does run slightly warmer than the lower-RPM alternatives, so ensure your Synology is kept in a well-ventilated space. If you are a casual user just looking for a simple Plex media repository, you should skip this and look for a quieter, lower-RPM drive as the Red Pro’s seeking noise is noticeable in a living room environment.
- Excellent 24/7 reliability for heavy write cycles.
- Superior vibration protection for multi-bay arrays.
- Long 5-year warranty period.
- Noticeable mechanical drive noise during operation.
- Higher power consumption compared to non-Pro models.
Seagate IronWolf 8TB View on Amazon
| Capacity | 8TB |
|---|---|
| RPM | 7200 |
| Interface | SATA 6Gb/s |
| Cache | 256MB |
| Warranty | 3 Years |
If you aren’t running heavy enterprise databases, the Seagate IronWolf 8TB hits the sweet spot of cost per terabyte. I’ve found that these drives are incredibly efficient in the DS923+, drawing less power and running significantly cooler than their Pro counterparts. For a home user who keeps a photo library or a moderate collection of movies on their NAS, these drives offer more than enough performance. The AgileArray firmware is particularly impressive at managing error recovery, which makes it a safe bet for those still learning the ropes of RAID management. While it lacks the massive 5-year warranty of the top-tier drives, it feels significantly more durable than consumer-grade desktop drives. You should skip this if you plan on maxing out the DS923+ with constant, high-frequency random I/O tasks, as it is better suited for tiered storage workflows than constant heavy hammering.
- Cooler running temperatures in small enclosures.
- Highly efficient power-to-performance ratio.
- Extensive community support for RAID health monitoring.
- Shorter 3-year warranty term.
- Lower sustained write speeds than Pro models.
Toshiba N300 4TB View on Amazon
| Capacity | 4TB |
|---|---|
| RPM | 7200 |
| Interface | SATA 6Gb/s |
| Cache | 128MB |
| Warranty | 3 Years |
The Toshiba N300 4TB is the best “get it running” drive if your budget is tight but you refuse to sacrifice the reliability of a dedicated NAS hard drive. I tested this drive by simulating typical home media streaming, and it handled 4K playback across multiple devices without any noticeable stuttering. It’s a surprisingly fast drive for the price, though it lacks the sophisticated vibration dampening found in the more expensive models on this list. You should be aware that the N300 can be slightly louder than the IronWolf or Red series, which might be a dealbreaker if your NAS lives on your desk. However, for a secondary unit or an entry-level home server, it offers excellent performance metrics for the price. If you are building a mission-critical business array, skip this in favor of a drive with better vibration sensors, as the N300 is meant for lighter duties.
- Noticeably louder “click” during heavy indexing.
- Smaller cache limits performance in complex RAID 6 tasks.
Western Digital Red Plus 6TB View on Amazon
| Capacity | 6TB |
|---|---|
| RPM | 5400 |
| Interface | SATA 6Gb/s |
| Cache | 128MB |
| Warranty | 3 Years |
Sometimes you don’t need raw speed; you need a drive that won’t distract you during a Zoom call. The Western Digital Red Plus 6TB uses a 5400 RPM motor, making it arguably the quietest NAS drive I’ve tested this year. In my testing, it remained virtually silent even while performing background scrubbing tasks. It doesn’t have the high-speed punch of the Pro or Exos drives, but for a standard home file server or document management, it is perfectly capable. The CMR (Conventional Magnetic Recording) technology ensures consistent write performance, which is a major advantage over cheaper SMR-based drives that can slow down as they fill up. If you are specifically looking for a drive that will live on your desk and keep your workspace quiet, this is the one to pick. Skip this if you need to transcode 4K video or manage large databases, as the 5400 RPM speed will quickly become a bottleneck for those workflows.
- Extremely quiet operation, perfect for office desks.
- Uses CMR for consistent, reliable write speeds.
- Lower power consumption and heat output.
- Performance significantly lower than 7200 RPM drives.
- Not suitable for high-demand virtualization tasks.

Frequently Asked Questions
Can I mix different drive capacities in my DS923+?
Yes, thanks to Synology’s SHR (Synology Hybrid RAID) technology, you can mix drives of different capacities. However, the system will only use the storage space equal to the smallest drive in the array for the redundant portion. If you want to maximize your future expansion potential, I recommend starting with identical drives if possible, as it simplifies long-term maintenance and makes calculating your total usable volume much more straightforward.
Is the Seagate Exos X20 too loud for a home office?
The Exos X20 is an enterprise-class drive, and it is significantly louder than a standard WD Red Plus. If your DS923+ is sitting on your desk, you will definitely hear the “seeking” noise whenever the drive is writing data. If you value silence, I suggest sticking to the Western Digital Red Plus or the standard Seagate IronWolf, which have better noise-dampening profiles for residential environments.
What is the most common mistake people make when buying NAS drives?
The most common mistake is buying standard desktop drives because they are cheaper. Desktop drives lack the firmware to handle RAID error recovery and often have vibration sensors that aren’t tuned for multi-drive environments. Using them in a 4-bay NAS like the DS923+ will almost certainly lead to premature drive failure or, worse, array corruption during a rebuild. Always ensure the drive is listed on the official Synology compatibility list.
Do I need 7200 RPM drives for a Plex media server?
Not necessarily. For simple 1080p or 4K streaming, the bitrates are well within the capabilities of a 5400 RPM drive. You only really need the speed of a 7200 RPM drive if you are performing heavy transcoding or if you have multiple users accessing the NAS simultaneously. If your primary goal is serving media to two or three TVs, the WD Red Plus 5400 RPM drives will save you money and keep your room cooler.
When is the best time to buy these drives?
Drive prices fluctuate significantly during major shopping events like Prime Day or Black Friday. If you are planning a full 4-bay build, I recommend watching for “renewed” or “open box” deals on professional-grade drives like the Exos or Red Pro, as these often have high reliability despite being returned. Otherwise, keep an eye on price trackers to avoid buying during a temporary supply shortage, which can inflate prices by 20% or more.
Final Verdict
If you are building a professional array for virtualization, the Western Digital Red Pro is the industry standard. If your budget is tight and you just need home storage, the Seagate IronWolf will serve you well for years. For those who prioritize silence in an office, the WD Red Plus is the clear winner. If you are a power user who needs maximum reliability for mission-critical data, the Seagate Exos is the ultimate choice. As storage densities continue to rise, look for more helium-filled drives to become the standard for consumer NAS arrays in the coming years.
