Western Digital Red WD10EFRX 1TB SATA3 IntelliPower 64MB Hard Drive (3.5 inch) [superbiiz.com] for only $81.37 after shipping. Use coupon code CRUNCH15 at checkout. This is by far the cheapest price I've seen on this hard drive, which is usually $99.99. This drive is well designed for raid configurations and it comes with a 3 year warranty.

One coupon use per household, but if you buy more than one, you can save on shipping. Price for two is about $170 after shipping, depending on location. I just paid $257.59 for 3 drives. After e*ates cash back of 1%, it worked out to $85 per drive.

Neweggbusiness [neweggbusiness.com] also has this drive for $89.99 after shipping with coupon code BEMCNAHE28, the next best price I've seen on this drive from a reputable seller yet.

Good review from Anandtech [anandtech.com], one from TomsHardware [tomshardware.com], and a less detailed one from PCMag [pcmag.com] if you just want a quick synopsis.

Anandtech calculated the rotational speed at 5400 rpm, but don't let that fool you. Read the benchmarks from the links I posted in the OP, these things aren't your average 5400 rpm drive. They have better power efficiency than most 5400 rpm drives and compete with the 7200s in terms of speed. All around solid drive with a better than average warranty. Their big claim to fame though is their handling of 24x7 operation and MTBF of one million (!) hours. These are specifically designed to thrive in NAS devices and servers.

Well, that's a debatable issue. SATA3 is useless for now. The Host-to-Drive speed they list as about 150MB/s TYPICAL(sic!), not Min-Max. From my own experience, 24/7 operation is beneficial for any drive. Right now I'm using a 10 year old Maxtor which has been running 24/7 all these years and still flawless!

Yeah, I have a few Maxtor's that are pushing 10 years too, great drives! 24/7 operation is not beneficial though, for any drive. It puts more wear on the drive as it is in operation constantly. However, these are built for constant operation like most enterprise drives (i.e. the RE4). True, the MTFB that manufacturers list is debatable, but WD is actually backing it up with a three year warranty. You don't normally find one that long on a consumer drive, especially at that price point.

I have seen the next best price at $88.39. No coupon needed and free shipping. Link [hookbag.com]

Yes, Sata3 is useless for HDDs right now. And yes, WD lists suspect read/write speeds, as do all HD manufacturers. But I posted three articles with real world benchmarks. If you want to know how fast are and how they perform against the competition, just read them. They're informative benchmarks from objective sources.

Well, I can add that this is not just my own opinion, same conclusion can be made out of well-known Google technical report on longevity of their drives. Start/Stop seems to put the most strain on the drive, as on your vehicle engine.

My Maxtor had been making very disturbing chirping sounds for many years until about couple of years ago that even made me once to panic and harshly back up the data . And it'd been running pretty hot (55-58 C). Still runs fine though and has only one relocated sector.

If you read the Google report [googleusercontent.com], there is still a positive correlation between high utilization and AFR. In year one, a highly utilized drive is nearly three times more likely to fail than that of a drive experiencing low utilization. And if you extrapolate the data in figure three, high utilization drives are nearly twice as likely to fail in the first 5 years (17% vs 10.5%). All they were claiming is that it isn't nearly as pronounced as drive manufacturers claim.

That's what I'm saying. If a drive survived the first year of non-stop running, it is likely to last forever (in google sense - 3-5 years). Extrapolation method is not the same or so reliable as is the real raw data.

I'm sorry, I didn't mean extrapolate. I merely cumulated the data given and there is a 17% chance of failure in drives with high utilization vs a 10.5% chance of failure for drives with low utilization. Bottom line, the more often you use a drive, the greater the risk of failure. And you can mitigate that risk by buying a drive that is specifically engineered to withstand the stress of higher duty cycles. That's why techs spend the premium on enterprise drives. This drive is the SMB/SOHOs equivalent.

In simple words, more use - more abuse - more chances of failure. It's just a common wisdom, not requiring any extensive studies to prove. Shelf it, never plug your drive in and shall last forever.

But that is an incorrect conclusion from Google data. It shows that the drives, survived the first year of operation are likely to last much longer that new fresh unused untested drives (vs. proven good). The drive failure rate correlates to uninterrupted 24/7 service more than to simple accumulated hours of operation, regardless of how achieved - by on/off or constant load.

I am not trying to pose as a hard drive expert, but this quoted statement may also have come out of HDD Marketing Dept. gurus rather than engineers, which is what I just tried to show.
