You are right, and the number of DOA's are definately worth mentioning imo. I will definately do some research on that, thanks!

The Toshiba drives are basically relabeled Hitachi 7K3000. They spin faster 7200 vs 5400 and utilize 1TB platters. The Toshiba's are raid friendly, so they shouldn't drop out of the raid, they use CCFA which is their version of TLER. But they have a shorter warranty, 3 years apposed to 5 years, that's for the USA, I couldn't find warranty information for Toshiba on the UK website but could for WD.

Hi,

The WD's also use 1TB platters. I doubt if the 7200 vs 5400 spin wil make a difference in network storage (but maybe i'm wrong here?). The WD Reds lower rpm results in lower power consumption (thus a bit less heat), and they also have the anti-vibration technology. But the Toshiba (and even more the Hitashi) drives also get some great reviews!
Anyone can shed some more light on these drives for my purpose?

Thanks!

Changed the setup a little bit. Could use some advice on the following choices:

- Motherboard : ASRock H77 Pro4/MVP // Asus P8B75-V
- HDD : 3x Western Digital Red 3TB // Toshiba DT01ACA300 3TB (= relabeled Hitachi 7K3000!) (put in a RAIDZ array)

I prefer the Toshiba myself, as that's what I run.

WD Reds use Intellipower and they don't publish their actual RPM speed. Spindle speed does matter in things such as random read and writes, as does the platter size/number of platters. Less head and platter movement to get to the requested data, the faster it can transfer. The difference is pretty much negligible, though. Think of the WD Reds as WD Green 2.0, built a little better and with TLER (which doesn't matter with software RAID such as ZFS). The CCTL on the Toshiba's is also a moot point, since that won't be used I do not believe, in a ZFS array.

I still recommend the Toshiba as disk vs disk, they are faster than the WD Red (minimal) and cheaper. I don't really care for WDC, so I may be biased.

Only 8 euro difference between these drives, so that is not an issue.

A am, however interested in the speed difference, and even more in relieability / durability differences between the two.

Well, the REDs are the same performance as the slow-as-dirt Green. Keep in mind that network link is most likely going to be the limiting factor for sequential reads and writes.

The thing that would make me consider the RED is the reduced head parking- the head parking process wears a drive rather heavily and many NAS workloads provoke lots of head parking. This is because most NASes will sit idle for long periods and then suddenly need to read a file or two and then go back to idle.

@OP

"Intellipower" is marketing babble. It implies that the drives have variable rotational speed, yet if this were true WD would be trumpeting it from the rooftops (and very loudly, too). However, every Intellipower drive has been clocked at a steady 5400RPM; I think the WD plan was to have drives of different platter densities, and to select a rotational speed such that different drives would have similar performance in terms of transfer speed - the higher the density, the lower the rotational speed (to a point).
