External SSD for occasional backups

Archiving documents, backing up family photos or duplicating important files requires neither excessive capacity nor maximum speed. An external SSD for these occasional uses should above all offer a reasonable price, since it remains unplugged most of the time.

Occasional transfers tolerate a few minutes of waiting: no need to pay for performance you will never exploit. Modest capacity suffices when backing up essentials, without multiplying versions or keeping years of archives.

What matters in this specific case

The same criteria as on the category page, but not the same weight: here is what goes up and what goes down.

See the category’s full grid

  1. Price

    Matters more coefficient 1.8

    Price becomes the decisive criterion for episodic use. Investing in a high-end model makes no sense when the drive stays stored between backups. Affordable models perfectly fulfil this mission without straining the budget. Compare offers to obtain the best ratio between capacity and price, without being tempted by superfluous functions.

  2. Capacity

    Matters less coefficient 0.6

    Capacity loses importance when backing up only essential documents. Between the lower level at two hundred and fifty-six gigabytes and the median at two thousand gigabytes, an intermediate value suits most occasional uses. The eight thousand gigabytes of the best level far exceed requirements: a modest size, sufficient for your important files, proves better.

  3. Read speed

    Matters less coefficient 0.5

    Read speed matters little when transferring files once a month. Whether the SSD reads at four hundred and forty-eight megabytes per second or three thousand eight hundred, the difference represents only a few minutes on a complete backup. Performance around the median at one thousand and fifty megabytes per second suffices amply. Paying more to save time on rare use constitutes waste.

  4. Write speed

    Matters less coefficient 0.5

    Write speed follows the same logic as read speed: its velocity matters little for spaced backups. Between four hundred and forty megabytes per second and three thousand seven hundred, the difference measures in minutes you can devote to something else during transfer. The median at one thousand megabytes per second suits perfectly. Prioritising reliability and price over this criterion remains the sensible choice.

What is not worth paying for

The features pushed in this category that make no difference in this context.

  • Recent high-speed connectivity

    The most recent connectors deliver throughput you will never exploit on occasional transfers. Standard connection suffices amply for spaced backups, without justifying extra cost that changes nothing to your actual use.

  • Reinforced casings and shock certification

    Reinforced protection targets professionals who transport their drive daily. For domestic use where the SSD stays sheltered, standard casing protects sufficiently. No need to pay for robustness you will not require.

  • Extended warranties beyond three years

    Long warranties reassure but cost dearly, especially for a lightly used device. On occasional backups, wear remains minimal. Standard manufacturer warranty suffices for this light use, without justifying additional investment.

Price ranges for this use

Orders of magnitude, not displayed prices: a price only appears on Kalyneo once it has been collected from a merchant, with its collection date.

Under €80

Under eighty euros, models offer sufficient capacity to archive documents and photos without advanced functions.

€80 to €200

Between eighty and two hundred euros, you obtain correct balance between storage space and decent speeds for regular backups.

Over €200

Above two hundred euros, performance becomes unnecessarily high for occasional use: this budget suits other needs better.

The products selected for this use

Ranked by relevance for this specific case, not by their overall score.

Our selection criteria for this use

A product only enters this list if it meets every one of these points. Its relevance is rated for this specific use, independently of its overall score in the category.

  1. The product displays a price below average for its capacity category.
  2. Capacity sits between five hundred and two thousand gigabytes.
  3. Read and write speeds reach at least the market median level.
  4. The casing remains compact and light for easy storage.
The buying guide for this category How to choose an external SSD: capacity and speed An external SSD is chosen primarily by storage capacity, then by read and write speeds. Performance varies considerably between models, with transfer rates ranging from single to fivefold. Price typically follows these two criteria. Read the guide
