【 Recommended USB Flash Drives 】


USB flash drives are convenient and everywhere, but we will give you some recommendations and tips when purchasing to avoid future troubles.

This page is non-affiliate. Our recommendations are based on our experience with USB Flash Drives

Choose Expensive and Small Storage Size


Within the same storage size, choose the one with a higher price.
Usually the price only differs by about 1,000 Yen

The larger the storage, it becomes cheaper when converted to the price per gigabyte.
Therefore, larger storage can be cost-efficient


The cost difference within the same storage size comes from the quality of the chip.


The larger the storage, the data density is much higher and increases the chance of a malfunction, as well as the difficulty to recover the data.

The size of the memory chip is the same. The density is 16times higher.



Use Domestic Products

Generally, the cost and quality of flash drives are directly related.
We recommend TOSHIBA, BUFFALO, SONY for domestic products. Using a domestic product does not gurantee the quality, but it does increase the safety.

Backing up on Two Devices

It is safe to consider flash drives as a tool to carry around your data. Do not use it as a primary backup media. Many people do not expect them to stop working, but it is a common occurence.
If you do plan to use it as a backup device, use a software that can backup on your PC as well.

In the end, flash drives from any maker will stop working. We recommend backing up on two devices as it is the best solution.

Do not Use No-Brand or Novelty Flash Drives

No-brand and novelty flash drives tend to be cheaper
The reason is that the used chip comes from those that did not pass the inspection after manufacturing.

Cheap chips have a higher risk of losing data and shorter lifespan. It is also common for them to be impossible to recover their data.


Do not Use Small Flash Drives

Smaller sized flash drives tend to lose all of its data when it malfunctions. It may seem apealing to buy a small flash drive, but its merits do not outweigh the risks.
The main purpose of flash drives is to save your data.If you consider the risks of losing your important data, there is almost no reason to buy a small flash drive if you plan to use it for its regular purpose。

Do not Use for Long-term Storage

Many people do not know, but flash drives have a lifespan. Even if you do not use it at all, the data can still be lost.

Do not use flash drives as a safe for your data. In 10 years time, the data could easily be lost.

Many people do not know about the lifespan. It does not necessarily mean that it will break in 10 years, but avoid using it in a way all of your data can be lost at once. We recommend using multiple devices to spread the chance of data-loss.

Use a Cloud/Do not Use a Flash Drive in the First Place

Save your important data to a online storage.
Unless it is for a corporate use, it is safer in terms of security and data loss prevention to use a cloud storage.

Suspicious Reviews/Information

Be cautious if the information and pictures are too detailed and suspicious. If the titile contains "Newest" or "High-Quality", they may have a convincing brand name, but they are usually a no-brand over-seas product.

When you check the reviews, check for the five star reviews and its details rather than the number of reviews.
