Built on a standard 3.5in format but with a thickness of 26.11mm, the 12TB Gold has a spindle speed of 7,200rpm and 256MB of cache.
The drive uses WD's 4th generation HelioSeal helium technology and PMR (Perpendicular Magnetic Recording) to support eight 1.5TB platters (discs) each with an areal density of 864 Gbit/inch2 and 16 reading heads.
A quick look at the flip side of the PCB reveals a Avago 6097 drive controller and a single Nanya NT5CC128M16IP-D1 DDR3-1600 256MB cache IC.
550MB a year work load.! i hope they mean TB
256GB cache ?

What about noise levels and temperatures? For home NAS usage, those are very relevant parameters when choosing HDDs.
It is never mentioned. Many people want to know, but every time they seem to “forget” that, or answer any questions about it. Definitely much more important than 240 or 260MBs throughput..
“WD claim a 550MB a year work load.” This doesn’t look right
I know – if 550MB per year, it would take you the entire lifetime to fill up the drive 😉
It IS 550TB
Real specs:
Designed with a workload rating up to 550TB per year
Up to 2.5M hours MTBF with a 5 year limited warranty
4th generation HelioSeal technology (12TB)
RAFF technology for vibration protection
RAID-specific time-limited error recovery (TLER)
Was going to buy seagate, but found these beauties at a great price so going in for 4 initially 🙂
Same spam bots on all the tech sites. I doubt “Cheryl” could earn that much in one month unless it was through illicit means.
550TB per year doesn’t sound much. That’s like 45TB per month, 11TB per week, 1,63 TB per day. How is this a high workload?
Compared to ssd drives it is a lot. Compared to seagate enterprise drives they are about the same. Barracudas are at 300TB year. I have done more than the specced workloads without any issues. Typical use even in enterprise is not that high unless you are writing TB data daily such as telecommunications companies do. This only recently appeared as part of hard drive specs. You can clearly exceed the workload but if the drive dies prematurely I bet they try to get out of warranty replacement. But having worked telecom, we constantly replaced hard drives due to heavy workloads back in the early 2000s.
