Cost Analysis


The Seagate Archive HDD 8 TB is currently available from €221,50. While it is not the most expensive disk out there it is hard to call this an affordable drive. However you might change your opinion when we take it’s capacity into consideration.

Low cost per GB

The Seagate Archive HDD 8 TB is huge. Therefore it’s major selling point is the low cost per GB. In fact, if you only consider cost per GB, it is currently the cheapest drive on the market.

Low power usage

But it does not stop there. This drive can also create huge power savings. Firstly it uses Seagate’s new PowerChoice technology. Although they are unclear how it works it effectively lowers the idle average power draw from 7.2W to 5W (0.625W/TB). The operational power draw is also lowered; from 9W to 7W.

But you power savings do not stop there. Imagine replacing 8 x 1 TB drives that are each using 8W by a single 8 TB Archive drive. With 24/7 usage you could save up to 490 Kwh per year, equaling a savings of no less than €103,02 in the Netherlands. Over a duration of 5 years that equals purchasing two of these 8 TB drives!

Keep in mind that Western Digital has introduced a 6TB Green disk that uses 3.4W idle (0.56W/TB). So there are even more power efficient solutions out there.

To summarize our findings the Seagate Archive HDD 8 TB certainly is not cheap to purchase but it has very low cost per GB and you will save you some money on your utilities bill in the long run.

    “limited to 55 TB per year”

    Dont just throw random words for the sake of artistic flavor. What you said there is horrendously wrong. Nobody is limiting you to write more per year.

      People aren’t limited, the drives are. They are mechanical devices that have wear and tear. Consumer grade drives are designed for 8 hours x 5 days usage whereas enterprise drives (and this Archive hdd) are designed for continuous operation of 24 hours x 7 days usage.

      You can find the 55 TB/year limit here;

      For Seagate the current limits are:
      Desktop: 55 TB/year
      NAS: 180 TB/year
      Archive: 180 TB/year
      Enterprise NAS: 300 TB/year
      Enterprise Capacity: 550 TB/year

      You can find out what happens here:
      “You may use SeaTools for Windows to measure your drive’s Annualized Workload Rate by running the Drive Information test. In the table above, compare your Workload Rate to the corresponding Workload Rate Limit. If your value is below the WRL then the drive activity is supported by the design. If the value is above the WRL then the reliability of the drive will begin to decline. Warranty policy does not change. However, Seagate reserves the right to limit warranty claims when drive usage exceeds specifications, as defined in the product manual”
