Guide to Choosing the Right External Hard Drive for Long Term Storage

Handed a list of hard drives, what would influence your decision about which one is the best for long-term storage?

Dollar / GB Cost

Among the most critical factor for deciding the best hard drive for long term storage is its cost.

Generally, when you look into a hard disk, you look at its performance as well as its mean time between failure rate.

However, for long term solution, the performance i.e the transfer speed as well as the MTBF value takes a backseat.

This is because drives used for long term storage are rarely used too often. They are intended for backing up data only. You will mostly find them thrown in a stowage space where they permanently reside with your data for good.

Hence, for a disk, that is seldom accessed but mostly stores data, affordability matters the most.

This is contrast to drives that are always in use. For instance, your primary drive where the OS is installed will definitely benefit from a high performance. Expensive SSD drives would make sense as well.

Rugged for Critical Long Term Data and If You Travel

There’s a very good reason why some of the most compact and sturdy military electronic equipment are rugged in construction.

They need to survive even in the harshest conditions.

Taking from this, an external hard disk that’s meant to hold files for long periods, maybe as a backup needs to survive harsh conditions as well.

While you may not be on a battlefield, the day to day activities of modern life results in a lot of stress exertion on equipment.

Rugged hard drives are mostly classified as drop-proof. This means that accidental drops from let’s say a shelf, will not be as fatal.

Shock Proof

If you want a hard drive that you can carry with you to each of your destinations, then one that’s classified as shock-proof will be a worthy gamble.

Shockproof external hard drives are by design built to withstand knocks and some falls. They are also resistant to significant amounts of vibration so if you’re always on the move and mostly on rough terrain, you will probably need long-term external storage that’s shockproof.

Water Resistance

Water damage is one of the worst things that can happen to any electronic device and it’s usually difficult to recover data if the hard drive has been exposed to a significant amount of water or moisture.

This may be defined by the IP rating (Ingress Protection) which determines the extent to which a device’s enclosure has been sealed, thus protecting the components inside it from intrusion and damage by the elements around.

SSD vs HDD for Long Term Storage

SSDs are fast. The hard disks are nowhere in comparison to the speed which the newer SSDs can provide. The newer PCIe v4.0 can even reach 8000 MB/s transfer speeds where as the nominal speed for hard disk is only 140 MB/s.

With that said, for long term storage, SSDs make little sense since they are very expensive. As mentioned earlier, long term storage entails that the disk is used only to store data and is seldom used.

If that is case here, there will be no point investing in expensive storage. We recommend the slower but inexpensive Hard disk drives.

Final Words

In this article we looked at some of the best external hard drives for long term storage. We looked at budget and premium, hard disk drives and sold state drives.

If you are looking for ultimate safety, it is important take into consideration how durable the external hard drive is. You need to make sure it is ruggedized since external hard disk are more prone to damage from fall and spills.

All in all, the good news is that there plenty of valuable options out there that you can choose. If you are looking to combine durability with speed, we would recommend you choose an SSD over an HDD.

Plus generally SSDs are more reliable against failure since they do not have mechanical moving parts.
