OK, I admit the prices of either are rather close, and prices can go either way depending upon if you pay “regular price” or “on sale price”. In addition, the “best” drives are never inside an enclosure where you can’t see the actual drive. They include the bottom of line drives.
And even more unbelievable is that “low power drives” (aka “green drives”) turned out to be a marketing ploy. Some companies have quit making them and/or re-branding them. Examples – see these links:
Now, back to drive comparative prices. I selected to use for comparisons, Newegg.com prices for Seagate drives instead of WD, or any other brands, because Newegg has a “Seagate Store” within the site that helped compare apples with apples. All drives are 4TB models.
First up is the External drive in enclosure.
Second and third drives coming up are the same 4TB bare drive at regular price and the on-sale price from last week’s email ad from Newegg. This is a bottom of line drive, and most likely the one inside the enclosure:
So, I am not “wrong”, but I am not completely “right” either. BTW, these are 5400rpm drives, I believe.
