How to choose an SSD or a HDD ?.

Here are the main features that we recommend you to take into consideration before buying a backup drive.

Storage space.

The choice of the “size” of your external drive, either an SSD or HDD, depends on your needs.

Most external hard drives have minimum 128 Gb of storage, which allows, for example, to store thousands of CDS in audio format is FLAC (and even more in AAC or MP3).

If you want to clone your entire computer, you will need more space (and maybe invest in a SSD).

Between to backup your music and back up your entire computer, there are not many shades.

For example, you can choose to back up only your files and your most important documents (photographs, e-mails..).


For connectivity, USB 3.0 is now the standard on the external drives.

This means that, when you transfer your music or videos, you can reach a read speed of about 100mb/s (instead of 30 Mb/s before).

Concretely, a USB 2.0 would take about an hour to transfer, a USB 3.0 does it in less than 20 minutes.

The SSD the fastest can go up to 550 Mb/s, but this depends on the devices to which they are connected.


If you intend to frequently carry your external drive, then we recommend that you choose a model that is resistant to shock.

Some devices meet the standards of the us army (MIL-STD-810F 516.5), meaning they can withstand 26 drops from a height of 1.22 m.

Note that the SSD drives are more rugged than HDDS, and some are even water-resistant.

Even if this is not specified, if you drop an SSD into the water, it should work once perfectly sec.

Some SSDS have a clue seals as may have smartphones.


The HDD and SSD have a limited life span, and that is why the guarantees that accompany them are relatively short, usually two or three years.

It is important not to be dependent on a single external drive. Ideally, you should have three copies of all your important documents : one on your computer or your phone, on your external drive and on a Cloud.


For many users, a storage disk is an accessory which is vital, and their choice is based, in large part, on the price.

Often, an older model will cost you less, so you can get a hard effective at a lower cost. Nevertheless, make sure that certain connections modern for example, are missing.


The larger the hard disk capacity is high, the more you will be inclined to store data ; but also the greater the risk of losing them. That is why, it is necessary to secure your disk.

There are two ways to ensure that your data is unreadable to others. You can encrypt the content using the encryption hardware or use an application, it will secure the whole or a part of your drive.

How to choose an SSD for a Mac ? .

The choice of a SSD should be based on the model of Mac you have. It is important to know that the drives to be semi-conductors of the last MacBook are up to 30 times more vivid than a HDD classic.

Then, to give a second youth to your old Mac and get a speed of at least 550 Mb/s, you will need a port powerful as the Thunderbolt 3. Connectors Thunderbolt USB-C 3.1 Gen 1 or Gen 2 also work.

If you have a 2011 MacBook Pro for example, and that the latter only has USB 2.0 ports, of which the maximum speed is 60 MB/s, then we rather recommend you to consider purchasing a hard drive.

The SSD external with the most recent are incredibly powerful, they are available in three or four capacities, 250 Gb, 500 Gb, 1 Tb and 2 Tb.

The cost difference between the models of 500 Gb and 2 Tb is important. So, before you start, check the storage capacity of your Mac in a way to guide you.
