PCMark Vantage and 7
For trace based testing, we are replacing the outdated PCMark 05 results with a pair of newer versions of the same. PCMark Vantage and PCMark 7 results will be included moving forward. We are also running PCMark 8 on samples as we receive them, however we do not yet have sufficient comparative data to make a useful chart. Vantage results tend to be higher as they show more of a raw / peak type of result measured during the trace, while 7 shows more of an averaged value over the time duration of the trace. Translation: Vantage shows max throughput while 7 shows how that throughput impacts overall system performance. You can easily tell the difference by looking at the results of the HDD (VelociRaptor), which scores higher under 7 since the overall system is usually doing other things in addition to accessing storage.
Given the throughputs and seek times seen in the previous pages, we can guestimate that higher RPMs and faster seeks are going to result in higher performance. That said, the 6TB Red falls flat in any tests which employ more of a multithreaded access pattern (i.e. QD>1). In those tests we can see an obvious dip (~50%) in performance of those tests. We anticipate the updated firmware will shift those results to look more in-line with that of the 4TB Red results (grey colored bar – 3rd from the bottom).

Good to know these are
Good to know these are affordable. I’ve still got about a year before I run out of space using 4TB REDs, then I’ll start upgrading with 6TB drives. I tried Seagate’s NAS drives but the one’s I bought (at least) were way too loud for use at home.
3TB is still the best $/GB at
3TB is still the best $/GB at $0.043/GB. Better density for the NAS drives, though not sure the price is worth it.
No. 5TB Seagate externals
No. 5TB Seagate externals are $190. $0.038/GB. I can’t buy them fast enough!
I think your failure premise
I think your failure premise is a bit contrived. No one should be running a RAID system of any type without full SMART checks on a regular basis at the very least.
I’ve personally had RAIDs
I've personally had RAIDs fail in that scenario even with SMART checks in place, as well as weekly full array data scrubs. Fact is that unless you have some form of TLER, a second drive failure that occurs mid rebuild will cause most RAID controllers to offline the array.
Ryan had also had such a failure (using Seagate drives), and I had to recover his array by imaging the non-failed drives and manually de-striping in software.
Curious Allyn, which imaging
Curious Allyn, which imaging software did you use to rescue that array ???
It wasn’t the imaging
It wasn't the imaging software that did the rescue – all it did was create images of the drives (and read past the unreadable areas after hours of timeouts / retries). One I had the images, I coded something myself to re-stitch, using alternating parity (i.e. two drives had unreadable sectors in (mostly) alternating areas relative to each other).
That was for my array recovery. Ryan's was easier, as he had just one drive with a small cluster of bad sectors causing his array to timeout. I was able to image that drive and re-stitch that array back together with a tool from Runtime Software – but with some custom settings I had to come up with myself, as Ryan's array was not easy for that software to 'lock' onto in auto mode.
So the pro is “better” &
So the pro is “better” & expected to last longer, yet is 6dBA LOUDER than the standard WD RED….
Also, did anyone else notice they changed the “Non-recoverable read errors per bits” to look better despite being the same?
It’s a 7200 RPM enterprise
It's a 7200 RPM enterprise spec drive. *Of course* it is faster / louder.
You should look into how
You should look into how Seagate is intentionally crippling consumer HDDs with low APM states and special firmware to scare enterprise customers into buying more expensive drives.
Can we mix and match Green

Hi I’ve got 3 existing 1year
Hi I’ve got 3 existing 1year old WD RED 4TB drives and am moving to a new Synology 1515plus. I’d like to expand my storage and am considering a RED PRO instead of buying another standard 4TB RED drive
My question is this, is it bad to mix a new 4TB RED PRO with the older 4TB standard RED drives in a RAID?
Thanks in advance
I have almost the same
I have almost the same question, except i have 5 x one year old wd red 3tb’s and am expanding to 8 drives…Would it be better to use 3 new pro drives, or stick with 3 new standard red drives?
Thanks in advance.
oh, and by the way…..Merry Christmas to all on here!
Pro drives would be your best
Pro drives would be your best bet, since they have accelerometers in like the Se drives to actively reduce vibration. Though even the newer plain reds have nasware 3.0 and so have software based vibration reduction, allowing upto 8 drives.
WD have also said they will honour warranties of those using older (1-5 bay drives) in 8 bay configs.
Perhaps on cost, plain reds would be better, don’t forget the red pro isn’t a home NAS drive, it’s louder, faster, and uses more power (around 5w/drive more), designed for heavier use.
