Asking about several drives to find which is the most reliable

Back to asking about hard drives (probably the third time now)

I have difficulty reading Backblaze's spec sheets since their equation seems to be drawn from peyote sessions around a campfire at 3:00 in the morning. Which of the following drives offers the best performance and best reliability of the bunch?

1: Hitachi Deskstar NAS
128MB Cache
7200RPM
8TB capacity
289.00USD (by pcpartpicker, but the real price is around 320USD on the link)

2: Seagate Barracuda Pro
256MB Cache
7200RPM
8TB capacity **
259.99USD

3: Seagate Barracuda Pro
256MB Cache
7200RPM
10TB capacity **
393.98USD (why!?)

4: WD Red
128MB Cache
5400RPM
8TB capacity
241.99USD

5: WD Red Pro
128MB cache
7200RPM
8TB Capacity
361.99USD (why!?)

I am almost considering putting an Ultrastar in this list, but since I am also trying to think about the cost of these drives, I will not be including them.
A note on WD Gold drives: yes they are exquisitely reliable. They are also noisy as a train horn and cost a ton of money. Since I am already going to put one of them in there as it is, putting two of them in there seems a bit strange, no?

  1. Just looking at generic reliability is probably not the way to look at things.

    Need to look at what YOUR environment is and see which drive has the best track record for that environment?
    How much read/write per day/hour, # of drives used/heat concerns, what kind of raid, etc?

    Drive track record: my knowledge is pretty sketchy on all of them, hence asking for advice. amazon has hundreds of negative reviews on wd red and red pros, but those are for the 3-4TB versions and none of them are recent (within last three months).

    Other than that, looking at reviews from other sites that take in hard drive samples sent by companies which proves "best foot forward" logic rather than generic performance and reliability doesn't assure me much.

    # of drives: 2 SSDs, 2 hard drives.

    mounting solutions: basically a suspension and anti-vibration specialized gear. I'll let you know when the case is done being built.

    Read and writes to the storage drives? I don't know, I tend to be a bit of a power user even on my three year old laptop and it keeps up with most of what i do. it occasionally derps and dumps but what machine hasn't?

    Hours per day; less than 8: most of which it will probably be at idle/standby/light duty. I have another drive similar to wd black for all my games and content creation.
    days per week; probably every day.

    The case will have a near ridiculous amount of airflow (one man's opinion), much of it will be focused on the drives.

    So no running spanned or parity RAID, not recording video 24/7 like from a video camera, no one else using the drive (like accessing data base entries or webpages) constantly.

    I personally have a bias agiasnt Seagate as they are so hit or miss to me, to unreliable to me from one generation/batch to the next.

    Your uses are well under the scope of any of these drives so there is no reason why any of them should not work well for your needs. Frankly I would get the most economincal to allow you to purchase another drive to backup that data to.
    At the end of the day you can look at all of the reviews you want but any of these drives could fail in 2 years or 10 and it is better to just have redundancy then hoping for reliability.

    Thank you for your help on that. While I will not get into RAID setups regardless of the reason, I wanted to know which one had more MTTF and better uptime compared to other drives at a decent bargain. (below 400USD each). Ultimately I went with the WD Red. I like the silence and cooler temperatures so I might go with the cheaper wd red over the pro. Though that performance and additional warranty does seem nice...

  5. Fortunatly an 8tb drive will have to have such high platter density that even 5400rpm will get you well over 120MB/s.
