There have been some fun and interesting stories lately, about how absurd the mark-up sometimes is for internal 3.5" drives. Yeah, you'll get full warranty and normal stickers. But going with a similar drive that's inside an external is sometimes cheaper. Way cheaper.

Amazon - WD 8TB My Book Desktop External Hard Drive - USB 3.0 - WDBFJK0080HBK-NESN

Amazon - $249.99 as of 04/06/2016

- $249.99 as of 04/06/2016 Newegg - $249.99 as of 04/06/2016

- $249.99 as of 04/06/2016 Best Buy - $249.99 as of 04/06/2016

Imagine the nice surprise folks experienced who happened to live near a Best Buy, bringing back their $249.99 8TB MyBook to pry it open, peeled back the sticker, and reveal that the HDD within is really...get this...an HGST (Hitachi) Enterprise He8 7200rpm 8TB drive that currently goes for $425.50 on Amazon! Just such a story is told so very nicely here:

HGST Enterprise He8 HDD Found in Early Retail 8TB WD My Book

I didn't quite have that good of luck myself, with no 8TB My Books in stock at any Best Buy anywhere near me. Check for yourself at Best Buy online:

There's certainly no guarantee that you'll also get the HGST variant, even if you do find the drive locally. Not sure if folks are getting the Hitachi helium enterprise drive when going with Best Buy online orders either.

Here's the thing. As I threw down my $250 at Amazon this past Monday, March 28th, I realized I was essentially rolling the dice, not really knowing what would be inside. But even if I got the 5400 drive WD variant, if it tested reasonably fast and was also very quiet, that's fine by me for my home lab!

On Tuesday March 29th, my My Book arrived. Opened it up, and the sticker shows it's a WD WD80EZZX. Better-than-expected benchmark scores seen below, and very quiet operation. I'm happy!

The equivalent spec'd WD Red 8TB NAS Hard Disk Drive - 5400 RPM Class SATA 6 Gb/s 128MB Cache 3.5 Inch - WD80EFZX goes for $343.92 on Amazon.

Arrives inside the same My Book that's sold at Amazon, Newegg, or Best Buy, for the same exact price. I realize it's not labeled as a WD Red drive for NAS. But I'm not particularly worried about a likely lack of TLER set for NAS use, given mine won't be used in a NAS. Instead, it's in my SuperServer, used for daily backups, just in time for World Backup Day.

I thought that I was totally breaking any chances at warranty. Then again, WD Support's Check your Warranty Status page where I simply key in my serial number off the drive itself (pictured above) looks promising. Date of manufacture of the drive is January 2016, model strangely shows as WDBFJK0080HBK, and the warranty expiration date is April 23 2016, about 2 years:

Doing some quick and easy benchmarks with this brand new drive revealed my performance looks a bit better than expected actually, with this Intel Xeon D SoC's six integrated SATA3/6Gbps controllers in my SuperServer continuing to serve my home virtualization lab quite nicely.

ATTO Benchmark run at defaults, subsequent tests gave very nearly identical results. Windows 10 on Supermicro X10SDV-TLN4F motherboard.

HD Tune Pro 5.60 run at defaults, subsequent tests gave very nearly identical results. Windows 10 on Supermicro X10SDV-TLN4F motherboard.

So I have saved $93.93 versus a Red, and got to have a little "fun" breaking in, as some unimportant bits of internal plastic retainers snapped off inside the enclosure, in exactly the same manner that others have experienced, detailed at:

This enclosure can totally still be used for other drives if needed, but no, I wouldn't say my My Drive is in a returnable condition, especially since I peeled the sticker partially back, to find nothing but bare metal below it.

What if you really want to get two WD Reds for a less
