Lexar Muse SSD Trades USB-C Port for Ultra-Thin Body

Key takeaways

The Lexar Muse SSD measures 3.8mm thick, according to Lexar’s claim.
It uses a custom magnetic connector instead of a standard USB-C port.
The slim body may help with travel, but the cable choice creates a new risk.
Buyers should check compatibility before treating it as a normal portable SSD.

The Lexar Muse SSD is a tiny portable drive that claims a 3.8mm thickness record. In simple terms, the drive stores files while taking up less space than many cards. Lexar pairs that thin body with a custom magnetic connector, not the usual USB-C port.

That design makes the drive stand out, but it also raises a practical question: will a thinner SSD be worth carrying a special cable? The answer depends on whether you value the smallest possible kit or easy connections to many devices.

What is the Lexar Muse SSD?

The Lexar Muse SSD is an external solid-state drive, or SSD. An SSD stores data on memory chips, so it has no spinning disks and can be smaller than an old hard drive.

Lexar says the Muse is only 3.8mm thick. That is close to the thickness of a few stacked bank cards, although the drive’s full size and weight matter too. The company presents it as the world’s thinnest portable SSD.

That is a company claim, not a universal industry award. Portable drives can differ in how makers measure thickness, such as whether they include a case, connector, or raised parts.

Why does the Lexar Muse SSD use a magnetic connector?

The Lexar Muse SSD replaces USB-C with a bespoke magnetic connector. “Bespoke” means Lexar designed the connection for this product rather than using a widely shared standard.

A magnetic link can help the drive sit close to a phone, tablet, or computer. It may also reduce the need for a plug that sticks out from the drive’s slim edge. But the accessory must match the connector exactly.

USB-C is popular because one cable can connect phones, laptops, cameras, and storage drives. The USB Implementers Forum’s USB-C guide explains the standard and its broad device support.

With the Muse, losing the cable could be more serious. A spare USB-C cable will not replace it unless Lexar sells a suitable adapter or extra cable. That makes the connection a key part of the buying decision.

How thin is 3.8mm in real life?

Numbers can sound abstract, so picture a standard pencil. The Lexar Muse SSD is thinner than the pencil’s width and far slimmer than many rugged portable drives.

The table below shows why the number matters. It compares the Muse’s claimed thickness with familiar objects, not competing products.

Item	Approximate thickness	What it shows
Lexar Muse SSD	3.8mm	Very thin drive design
Three bank cards	About 2.4mm	Thin, but still smaller than the drive
Standard pencil	About 7mm	Rough visual comparison
USB-A plug	About 12mm wide	Older plug shape needs more room

Thickness alone does not tell us how fast the drive is. It also does not show its storage capacity, heat control, or drop protection. Those details will matter more to people moving large video files every day.

What are the benefits and drawbacks?

The biggest benefit is portability. A 3.8mm drive could slip into a wallet-sized pouch, camera bag, or laptop sleeve with little extra bulk.

It may suit photographers, students, and travellers who move files between locations. The magnetic design could also make short connections less awkward, because the drive can stay aligned beside a device.

The main drawback is the custom cable. A standard cable usually works across many products, while this one ties the drive more closely to Lexar’s accessory. Buyers should ask three questions before ordering:

Does the package include the magnetic cable?
Can the cable be replaced easily?
Does the connection support the speed and devices you need?

There is another trade-off. A very thin case leaves less room for cooling, shielding, and protection from drops. Until Lexar publishes full technical details, shoppers should not assume that the smallest drive is the best drive for heavy work.

Who should consider the Lexar Muse SSD?

The Lexar Muse SSD makes the most sense for people who want a slim backup drive and control the devices they use. It could be handy for moving photos from a laptop or keeping a small copy of school and work files.

It may be less useful for families with mixed devices. A home with USB-C phones, older computers, and game consoles may prefer a drive with a normal port. That choice avoids adding another cable to the drawer.

People who edit high-resolution video should wait for full speed, capacity, and sustained-write details. Sustained write means how well a drive keeps writing large files after its short burst of speed ends.

What does the Lexar Muse SSD mean for portable storage?

The Lexar Muse SSD shows how storage makers are chasing thinner hardware. The 3.8mm claim is easy to market, but a connector can shape the whole ownership experience.

For buyers, the lesson is simple: measure convenience, not just thickness. A drive that is 3.2mm thinner but needs a rare cable may be harder to use than a slightly thicker USB-C model.

Lexar’s design could still prove useful if the cable is durable, replaceable, and fast. Until those points are clear, the Muse is best viewed as an interesting ultra-thin option rather than an automatic choice for everyone.

FAQs

What is the Lexar Muse SSD?

It is a portable solid-state drive that Lexar says measures 3.8mm thick. It uses a custom magnetic connector.

Why doesn’t the Lexar Muse SSD use USB-C?

Lexar appears to use the magnetic link to fit its thin design and keep the drive close to a device. The company must confirm the full technical reason.

Who should buy the Lexar Muse SSD?

It may suit users who want a very thin backup drive and can keep its special cable safe. Others may prefer standard USB-C storage.

Lexar Muse SSD: the verified specification

Lexar’s September 4 IFA announcement says the Muse measures about 3.8mm at its thickest point and tapers to 1mm at the edge. The company claims sequential read speeds up to 1,050 MB/s and write speeds up to 1,000 MB/s. It also says compatible iPhones can record Apple ProRes 4K video at up to 120 frames per second directly to the drive.

The physical constraint is the story. A standard USB-C receptacle would consume too much of the available thickness, so Lexar created the SnapLink Magnetic Cable. Spring-loaded pins contact the drive; the other end terminates in USB-C, with a Type-A adapter reported by TechSpot. N52-grade magnets also secure the drive in a sleeve designed for compatible MagSafe iPhones.

The Lexar Muse SSD is thin because the removable cable absorbs part of the connector system; it does not eliminate the need for a cable. Buyers gain a flatter drive but must keep the proprietary SnapLink component available whenever they want to transfer data.

Why the connector matters more than the record claim

Thickness records are difficult to compare because manufacturers may measure different parts of a tapered enclosure. The practical question is not whether Muse is the absolute thinnest under every definition, but whether its mounting and cable system improves a creator’s workflow. Lexar correctly describes the superlative as its own claim; independent outlets likewise frame it as claimed rather than independently certified.

A proprietary connector concentrates replacement risk. If the SnapLink cable is lost or damaged, an ordinary USB-C cable cannot plug directly into the SSD. Lexar has not yet published replacement pricing, a long-term availability commitment or a cross-model compatibility table. Those details can matter more than a few millimetres when the drive holds footage needed on deadline.

Performance claims also need context. The stated 1,050/1,000 MB/s ceiling is an “up to” figure. Sustained write speed can change with capacity, NAND configuration, temperature, remaining free space and the host device. Direct ProRes recording is a useful compatibility statement, but it does not guarantee the same throughput on every phone or format.

Who benefits from the Muse design

The strongest use case is a mobile video rig where the SSD stays attached to a compatible phone and bulk is tightly constrained. A creator who moves the drive among several laptops, cameras and tablets may prefer a conventional USB-C port because any certified cable can be substituted.

The architecture echoes Hohem’s detachable 4K camera: modularity shifts convenience to the connection between components. It also resembles Xreal Aura’s external compute design, where moving hardware out of the main body changes weight and dependency at the same time.
