So why are we all so hooked up about performance on hard drives?
Technically we have all been conditioned to ask about disk performance by comparing the disk specifications between competing manufacturer drives towards ascertaining all our options.
Drive specification and performance are merely guidelines and are normally used as calculators for performance ratios when attached to drive controllers within servers. This is seen clearly when drives from differing manufacturers are tested in say NAS "A" and NAS "B". NAS A" may return a faster throughput for Drive A whist Drive B in NAS "B" may result in different output. This seems like a disparity but it's not as the combination of controller and drive can produce unexpected results.
So, in short, a competent system integrator will test a host of drives from different manufacturers and have results that provide performance, compatibility and, with historical use, reliability as well.
At SimplyNAS we have done exactly that and optimized the server and drive performance ratio to ensure customers get the best bang for their buck, without any compromise. Our list is based on Enterprise, SMB and Home/Workgroup Network Attached Storage appliances. The following manufacturers are featured – (Seagate, WD/HGST, Toshiba) Note: HGST no longer produces drives independently and all Enterprise drives are now co-branded as WD/HGST. The older HGST reputation of reliability should not be used as a measure for future purchases.
Enterprise Class NAS Servers
WD Ultrastar – Toshiba Enterprise – Seagate EXOS drives – Can be both SAS and SATA HDD
All other category drives are not recommended because of the reliability, performance and longevity of the drives and data protection needed.
SMB Class NAS Servers 8 Bay and above
The Enterprise drives can be deployed if price is right – however, if not then the Seagate IronWolf PRO and similar drives are fine, i.e. WD RED Pro, etc.
SMB Class NAS Servers 2 – 6 bays
NAS drives, and any other PRO drives. WD RED PRO or IronWolf / IronWolf PRO - Again, if Enterprise drives are offered without additional cost snap these up.
Home/Workgroup Class NAS Servers
NAS drives are well suited, NO desktop or Green drives – WD RED and WD RED PRO, or IronWolf / IronWolf PRO.
As for current storage we have just completed our long-term testing of Toshiba Enterprise drives, and if we were to draw comparisons they appear to closely resemble drives from the same HGST Enterprise mold with great pedigree we used a few years ago. Solid as a rock and dependable, with excellent performance ratios as well.
So, these will now form part of our current enterprise category recommendations. Together with Seagate EXOS the Toshiba Enterprise drives will follow suite. Exception to the rule will be the IronWolf PRO, as these will also be recommended for capacities of 14TB and over, to complete the category of highly recommended enterprise class drives with criteria that matches reliability, longevity and value for money. As far SAS interface the only two models that qualify within our recommendation chart are the Seagate Exos and Toshiba Enterprise drives.

But what does this translate to in actual practice?
One example we can share is from our years of experience of burn-in and testing of 100% of the Configured NAS servers that we integrate from QNAP, Synology and other manufacturers. This occurs immediately after production, before they are shipped to their new owners. We install a full set of drives, sync a RAID array, and transfer hundreds of Terabytes to test functionality of the unit. The drive sets used for this activity are very heavily used. We switched, about 5 years ago, to enterprise grade drives and those drives are still working flawlessly. Hence, our confidence in what we recommend.
