Hard-disk Buying Guide: Which HDD is best for your needs

by | May 29, 2021 | Tech Tips | 2 comments

In the era of solid-state drives, the conventional mechanical hard disk might seem obsolete but it is not the case. If you want massive storage with a great price to performance ratio, hard disk is still #1 in terms of that. Even if SSDs go any cheaper, it can’t ever compare itself to the price HDD’s come in. Still while thinking to buy any HDDs, you find yourself with a bunch of options to choose from. It might be somewhat confusing, as the names in which it comes in often seem irrelevant to what it serves. Sometimes you need a hard disk buying guide before you plan to buy one.

Although there are many companies to choose from, Seagate is still one of the most reliable and popular options available out there. The following are some of the options that Seagate offers in their hard disk lineups:

Different types of Hard Disks

It has a SATA3 interface and has AgileArray with CMR technology NAS Optimisation. IronWolf comes with a 5-year warranty. At the time of writing this post, it comes with a maximum capacity of 18TB.

Ironwolf Pro is better than IronWolf because it comes with a toughened body and it has better software and hardware support. It is also structured in such a way that it has vibration reduction even when stacked with multiple hard disks in a NAS.

Hard-disk buying guide

Although there are many options available in hard-disks, but all have their specific use and purpose. Also the more durability addition to HDDs, the more expensive they get. So there will be no sense in buying a rugged hard-disk built for gaming or server when all you’ll be doing is watch some videos or surf the internet.

So if you have a specific demand for the computer build, like if it is meant for server build for example, then only you should choose hard disks like IronWolf Pro or IronWolf. If you’re using a hard disk for a basic build, then you should be fine with the entry-level hard disks available, using some precautions. A typical HDD of some good manufacturers like Seagate, Western Digital, or Transcend can typically last between 5-10 years, or more, depending on how well you take care of it.
