Best value for money flash storage before jumping on used enterprise ssds. You will often find them at a reasonable price if you're patient and last but not least have a look at the 3 year rescue service included because things happen when it comes to nas/server storage:)

Early on its hard not to be satisfied with the Seagate IronWolf. The NAS grade hard drives are more expensive than regular ones but, we hope, they are designed to run 24/7 for a long time. It is whisper quiet which was a really nice change from my old set up. But...the only review that will count is the one I could give you in about ten years.

Used these on a Dell Perc 710. 2000MB/sec average read speed on a raid 6. Breathes new life into an older systems that cannot be easily replaced. 3 to 4 times the throughput of 10k SAS disks.

I bought this as a replacement & upgrade to the 1 TB HDD that came in my Alienware 17 R5 laptop. Once I had downloaded, installed, and used Seagates DiscWizard software to clone the old drive onto the new, the swap was done. And it went without a hitch. My boot & shutdown times are now small fractions of what they used to be. Very pleased.
I've been running a few of these in my FreeNAS for about a year, and when it came time to increase storage size I bought a few more without hesitation. Nice that they give detailed drive information for monitoring (temperature, load averages, etc) and are whisper quiet. Shock protection is also great, I dropped one on tile floor while I was getting it out of the box and it had zero problems passing all tests and badblocks, not a single dead sector. I've had a few consumer grade drives fail in my NAS over the years, but not a single one of these has come close to breaking. Well worth the slightly higher cost if you have critical data to back up (or you just want additional peace of mind) :)
NOT 7200 RPM as the headline claims. They are 5900 RPM. If you really dig into the specs it says 5900 RPM in a few places Otherwise seem to work OK, but it’s only been 1 day
The drive has been installed in my working array for two months now. Performance is solid.
This drive was very easy to install plus it's quiet and very fast. Cost was reasonable and Windows 10 Pro was installed in record time. I should have made this change years ago.
SSDs are marvels of technology, packing Terabytes of information into business card physical dimensions. Seagate has been in the business since forever. and positions this model drive as NAS-specific. I put it into a home NAS, replacing a WD 5 inch HDD with 45000 power-on hours on it. Hoping for a similar lifetime, when 250TB drives are going for under $100.
