Warm? ... 4tb WD Blue = $99

The 4TB HGST Deskstar NAS drive would be a better deal as its motor and platter bearings are rated for 24/7 operation (the blues are only rated for 8 hour operation) and if using in a large storage configuration have vibration sensors to negate read/write head vibration from other drives. The WD Blue drives are also 5400RPM/64MB while the HGST Deskstar is 7200RPM/128MB and the HGST also has another 1 year of warranty support (WD Blue 2 Years vs HGST Deskstar NAS 3 years.) Their also both the same price if you get the emails from Fry's.

With all the complaints of clicking & bearing noises I am wary of those particular HGST.

Bearings only rated for 8 hour operation? Interesting. Where does it state this? Did not see that on their PDF spec sheet. I have several 250gb Blues from Dell workstations with 40-50k hours on them which likely ran for years at a time. Sure you are not confusing business class HDDs which are rated for 100% duty cycles? ie, continuous I/O seeking.

While not specifically stated within WD's datasheets (Seagate however list this in their datasheets; See the specification of "Power On Hours"), if you ask a WD engineer or do a little googling (or if you've ever been in an enterprise setting using WD Blue drives trying to save a dime or two, god help that IT manager), you'll know that this is a commonly known fact. Also, check out the compatibility lists for Synology and QNAP NAS, you'll notice that all WD Green/Blue & Seagate Barracuda Drives have been omitted due to their high failure rate in a 24/7 environment.

I'm not stating that its a guaranteed failure, only that their failure rate will be much higher and I'd rather have a higher quality drive.

Also, just because a drive is loud does not mean that its a bad drive. I own many systems with Enterprise Grade drives that are super loud but have been chugging along for years. Also HGST's reliability rating is top class (See Backblazes HDD reports which are posted every Quarter.)
