I review many products here at Finder across a wide range of tech categories. Recently, Samsung sent me a small bag containing their new storage devices, including a 2TB Samsung T7 Shield SSD, a 256GB Samsung USB Type-C flash drive, and a 256GB Samsung EVO Plus microSDXC UHS-I card. Go.

That’s a lot of storage, but there’s a big problem with storage. We all need it, often we don’t have enough of it, and yet…storage is boring for most consumers.

While there are absolutely underlying physical and logistical differences between each type of storage, as a consumer what you really need to know is that you are getting the best value and the right type of storage. for your needs.

As such, while I’ve tested all three storage devices, I really want to highlight where they fit best, and in fact where they don’t.

It’s not just unique to these specific devices and brand, as any external SSD, USB stick or SD card would have the same basic considerations in play. It’s worth knowing where you’ll get the best value for money or where you could save money by moving your choices to a better storage format.

Each drive has been tested equally so you can compare their claims to their performance, but I’ve also highlighted where they would make the most sense based on price, capacity and features.

Samsung T7 Shield 2TB Portable SSD

Samsung has a long history of portable SSDs, which is why this is the T7 SSD, not the T1. One of the main selling points of this drive is that it’s sturdier than most external SSDs, with a rubberized corrugated shroud around the drive itself.

The drive itself supports USB 3.2 Gen 2 with speeds of up to 1050MB/s read and 1000MB/s write, though you’ll need a PC or other eligible device to reach these speeds. Tests with a Surface Laptop 5 via USB-C slightly exceeded these results with peak reads or writes of 1072.28MB/s, although they dropped significantly for random read/write tests , as expected.

Who is it for ?

This is a rather specific reader due to its rugged IP65 rated water resistance features. Like most external SSDs, you can achieve blazing speeds if that’s what you need, but at a significant cost for the actual storage you’re getting. Older or slower SSDs may be cheaper, but if you need speed and a generally robust drive, it’s worth considering.

256 GB Samsung USB Type-C flash drive

MSRP: $80

USB drives are nearly ubiquitous these days, and they’re also very affordable overall, but there can be differences in throughput and build quality. Buy a cheap USB flash drive and you’ll probably get something that meets old USB standards or has a flimsy plastic casing.

That’s certainly not the story of the bundled 256GB Samsung USB-C drive, which claims speeds of up to 400MB/s using USB 3.1 – although it’s worth noting that’s only for reading speeds. Using Crystal Disk Mark again, I was able to achieve peak speeds of 362.28MB/s, but only 114.27MB/s when writing files to the drive.

Who is it for ?

It’s a pretty sturdy drive, although I suspect most users will probably lose its metal cap fairly quickly. While it might seem like a “cheap” alternative to the larger external SSD, the price per MB is actually pretty close when you break it down.

That being said, if you have smaller files and need a faster USB drive, this is a solid option. Naturally, there are millions of alternatives at different price points, although you can expect slower speeds with cheaper drives.

microSDXC Samsung EVO Plus 256 GB

MSRP: $85

MicroSD cards occupy a very specific niche in the storage category, as they are designed for devices that can read them, typically the domain of some smartphones and many DSLRs and camcorders.

Samsung’s 256GB EVO Plus is a premium card – again, like USB drives, you can pay a small amount for a basic microSD card, or a bit more for a card with upgraded internals and faster read/write speeds.

In theory, the Samsung EVO Plus 256GB microSDXC should be plenty fast for most users, with quoted transfer speeds of 130MB/s. For the true business audience, even faster UFS-II options are also available.

Here, my test solution is doing this particular card no favors, as the test rig does not have a microSD card reader.

This helpfully highlights a pitfall to be aware of, and that is interfaces. Not only their absence, but also the fact that if you use older equipment, adapters or converters to access certain devices and drives, they can seriously affect the speed of your experience.

For what it’s worth with an external SD card reader used, Crystal Disk Mark achieved a maximum read speed of 16.15MB/s and a write speed of 15.5MB/s, well below claims. from the menu. It’s the fault of the reader and the testbed though. The idea here is much more that you would buy this particular card because you needed the higher sustained write speeds to shoot 4K or similar video.

Who is it for ?

In this case, especially video or photography professionals where a slower card won’t meet their sustained throughput needs, whether for high-quality continuous video capture or photo bursts where lag could lose a vital image. It’s also remarkable to have a 10-year warranty, which is a nice touch.

If you’re just after stocking up on a cheaper smartphone or wanting to boost your Nintendo Switch’s storage, that’s a bit of a stretch – but quite nice, given the long warranty.
