We got the complete spectrum of the rainbow, great WD
Now regarding to those HDD, they are labeled for "datacenter" work, may I ask, there is any suitable difference using this and not the RED "optimized" NAS drives or its just for the omps?
Well. Here's what's going on. There's a major shift going on in the storage industry. SAS, "enterprise grade" drives, multipath, extremely expensive hardware, all of that is slowly being discovered for what some of us always knew it to be.... extremely expensive bullchips. Two cheap somethings and some software or configuration to make it redundant often works out better than one super-expensive high-availability redundant-this-and-that. Software based storage has been eating the large SAN arrays, and the software based storage can usually deal with cheap disk even better than the hardware controllers could cope with high quality disk. Look at ZFS as an example. You *CAN* build your ZFS filer out of high quality SAS with redundant pathings, but the value added over just getting inexpensive SATA drives is not that great.
HDD storage in the data center is rapidly heading for archival use. They've got to figure out how to create the data center equivalent of what a home user's WD Green drive. The WD Red is already optimized to the general task, except that it is missing some of the vibration resistance that would be a nice-to-have in a data center drive. Problem is, it looks like they haven't really figured out that what they really need is to mark down the prices on the drives. More likely, they actually know that some of us don't care about warranties and are very happy to get ahold of a desktop drive for ~$275-$300, or
shuck a WD enterprise 8TB for ~$250, or just use the $200 8TB SMR drives for archival quality storage and use SSD for everything else.
Part of the problem was that their rainbow color lineup didn't really have anything optimized to be suitable for software defined storage on a large scale, so what a lot of us have been saying is to just go for the inexpensive WD Red and then just don't worry about the vibrations, which is not a horrible issue anyways. Unless the WD Golds are made out of gold, as a designer I'm not seeing a ton of value. I think at the suggested price points that WD Gold is more of an attempt by WD to make more gold for itself, but I don't know how well that'll work out for them.
