Hard Drive comparison

Hello everyone,

I am building a new system that I will hopefully be purchasing soon and have a simple question. Many prices on the hard drives at new egg do not make sense to me. I see WD Caviar Black 1TB 7200 drives at 6GB/s being $10 cheaper than the same model, but 3GB/s. Likewise, there is a 1.5 TB drive with the same specs (and 3GB/s) for about $75 less than either of the ones posted above, and yet another 1.5 TB drive priced at $50 higher but has a lower transfer rate. Here are links to the ones in question


Clearly there is something here I am missing. If anyone has any suggestions (even if it is to get a completely different drive), please post here. I am simply trying to make the best decisions regarding my new setup, and could use the communities' expertise!
Thank you all in advance

  1. Well being their black series makes them their high end consumer products, You are not missing anything really the price is what it is and every new shipment of drives looks to have brought a price increase so maybe older stock is still selling cheaper. This 1.5TB drive is definetly the best buy out of the bunch http://www.newegg.com/Product/Product.aspx?Item=N82E16822136793&nm_mc=AFC-C8Junction&cm_mmc=AFC-C8Junction-_-RSSDailyDeals-_-na-_-na&AID=10521304&PID=4176827&SID=6jln42nir9mw
    Performance wise they should all be similar since no HDD currently maxes out the SATA 3GB std.
  2. In addition, hard drives are a consumer product and as such are subject to "supply and demand" in Economics. Higher prices imply product shortages (supply unable to meet the demand).
  3. If you read the description you would see there are differences between them whether its the structure, size of storage or the cache.

    If you dont mind me asking what is you application of use? If your looking to spend that kind of money you should look into Solid State drives as they much more faster

    info for you http://en.wikipedia.org/wiki/Solid-state_drive

    @darlingpchelp - My main uses for it will be storage and programs that I do not frequently use. I am building a new system from scratch and will be getting an SSD for my OS and main programs, but want a larger drive to save files to. I understand there are differences in the drives, but my post was in the interest of getting clarification as to why the prices seem so backward. Take the first 2 links for example. Both are the same size and RPM, but one is 3GB/s with a 32MB cache and actually MORE EXPENSIVE than the second link which is faster and has a larger cache. I apologize if my original post made it sound as though I thought they were all the same. They certainly are not, but just as certainly seem to have a lottery wheel or some other RNG device set up as the process of determining the prices! : )
    Thank you all again for the input. Any further suggestions on which is the best deal are very welcome.
  5. I beleive from what I am reading the difference is quiet faex is loader then the fals. Also the number of plates they use internally obviously if they are the same size the more expensive will have less plates. check out this forum there are benchmarks as well :) hope this helps http://www.hardwarecanucks.com/forum/storage/31119-western-digital-black-wd1002faex-vs-wd1001fals.html
  6. According to this review of the Caviar Black FAEX, the reviewer notes that some have complained about the noise levels of the drive, but "while it does emit a low whir, it's still far from noisy, and is only likely to cause a problem in a silent PC".

    Gets a very good write up for the price of the HD.
