For the last few days we have been banging around the idea of large 14TB disks and we wanted to source the fastest, most reliable, least expensive disks possible. We know the Seagate BaraCuda is targeted to desktops / workstations and the Seagate IronWolf is targeted at disk arrays, wanted to know the physical difference between these two.
When the IronWolf was released under Seagate’s new branding strategy a few years ago, the difference was both performance and sensors. Specifically, the IronWolf was a little be slower than the BaraCuda but it had motion / impact sensors. We found the IronW
olf 14TB to be about 10% less expensive than the BaraCuda 14TB which did not make much sense to us so we decided to check the detailed spec.
Unfortunately Seagate apparently does not want you to make comparisons between the disks because they use slightly different specification sheets for each one. To get around this we spent an hour or so combining the two sheets into the spec’s you see below.
You can see that the BaraCuda 12TB and 14TB disks now have the same performance (transfer speed and latency) while on the older 10TB and 8TB models there is a tiny difference.
To summarize, the difference between the BaraCuda Pro and IronWolf Pro 14TB is:
The IronWolf has some additional sensors- The IronWolf is rated with a 20% increase in expected life (MTBF)
- The IronWolf and Baracuda use slightly different amounts of electricity
- The IronWolf CAN be used in a disk array, where as the BaraCuda is spec’d to be standalone (although we are fairly sure it would work fine in most arrays)
- The IronWolf is cheaper (at least in April 2019 – see screen shot of Amazon prices to the right).
This can all be summed up with, there appears to be no advantage to buying the Seagate BaraCuda Pro. Just buy an IronWolf and be happy 🙂
