Best Hard Drives for ASUSTOR AS6508T NAS in 2020
The mechanical hard drives you can install inside your desktop PC aren't designed for continuous use in Network Attached Storage (NAS). This is where specific NAS drives from the likes of Seagate and Western Digital come into play. We've rounded up the best drives you should use in the ASUSTOR AS6508T.
Seagate IronWolf is a series from the company for NAS installations, rivaling Western Digital's Red. Packing similar technology, named AgileArray, which offers enhanced performance and reliability over traditional desktop-class hard drives. These drives can be installed in a configuration of up to eight. If you need a little more performance still or wish to fill up a NAS with more than eight bays, you'll need the IronWolf Pro.
Western Digital's (WD) Red family of hard drives are manufactured for NAS use, and like Seagate's IronWolf can be deployed in systems that support up to eight bays. Backed by a 3-year limited warranty and a powerful brand in the storage market, WD drives are well known to be of top quality, and they last a long time. The Red series isn't the fastest batch of hard drives on the market, but using them in a RAID formation can make up for this.
HGST is part of Western Digital, so you can expect similar performance, reliability, and customer service experience as you would with the parent company. Vibration protection and a million hours MTBF (mean time before failure) make these NAS-classified drives ideal for deployment at home or in a small office. These drives are relatively expensive, but you get better speed than WD Red and Seagate's IronWolf.
Seagate has the IronWolf Pro available for NAS owners who need more performance with faster 7,200 RPM motors and up to 250MB/s of sustained data transfer. There's an extended warranty that covers up to five years and a 300TB per year workload limit. These are heavy-duty storage devices for a NAS that can go into units with up to 24 bays.
Just like Seagate, Western Digital has a "pro" series of drives, which are even more capable than the standard lineup of NAS storage options. Supporting up to 24 bays, these drives come rocking a 5-year WD warranty and more advantage features, including 3D Active Balance Plus and error recovery controls.
Seagate's IronWolf SSD range takes everything that makes the IronWolf HHDs so good and turns it all up to 11. That's because these are solid-state drives and not mechanical hard drives. That means no motors and moving parts. These drives start from 240GB with a 560MB/s sustained transfer speed for enhanced performance compared to mechanical drives. They're a little more pricey, but you get the same 5-year warranty.
Like the IronWolf SSD series from Seagate, the Red SSD family of drives offer improved transfer rates compared to normal NAS HDDs and comes with a 5-year warranty. The price hike can be justified by the performance bump alone, not to mention lower power draw and no mechanical moving parts.
If your NAS has an M.2 slot for a rapid SSD like the Samsung EVO Plus, you should consider buying one. These aren't technically used for expanding the capacity of your NAS per se but instead are used to store frequently accessed files. M.2 NVMe drives are considerably faster than SATA hard drives and SSDs, making these ideal for a NAS with multiple users.

When looking at hard drives for your ASUSTOR NAS, you'll ideally want to aim for a drive with a 7,200RPM motor and 64MB of cache for mechanical drives or an SSD of any size if you have the available funds. Really, for storage, all you need to bear in mind is the capacity and price. M.2 SSDs can be bought to add rapid cache drives and make accessing files quicker.
We've used the Seagate IronWolf for years without fault and find the drives to be well priced to boot. The same can be said about the Western Digital Red, which are almost identical to Seagate counterparts. If you want to expand on your NAS storage, you'll want to aim big with the more pricey Seagate IronWolf Pro and Western Digital Red Pro.
