External SSDs have rapidly overtaken HDDs as the preferred choice when it comes to mobile storage solutions for Macs and Windows PCs. Not only are they more durable compared to portable HDDs, but also competitively priced for their speeds and capacity. In this round-up, we have included five USB 3.2 SSDs from Crucial, Kingston, ORICO, Samsung, and Sandisk. These 1TB USB 3.2 SSDs offer universal compatibility with every Type-A and Type-C port. At the same time, they deliver a combination of stellar performance and affordability unrivaled even by high-end thumb drives.

Our Pick: Samsung T9
Among the portable SSDs compared, the Samsung T9 is our top pick for its exceptional sustained performance and build quality. In our stress tests, it outperformed the rest of the pack, maintaining a impressive sustained write speed throughout a massive 400GB folder transfer long after the SLC cache was exhausted.
The onboard USB 3.2 Gen 2×2 interface can further unlock its full potential with speeds close to 2000MB/s, provided you have a port to match. Plus, its 3-meter drop protection and full-disk 256-bit AES encryption offer peace of mind for both physical and data security. It also come with a generous five-year warranty.
The Alternatives
If portability is your primary concern, the Kingston XS1000 and XS2000 remain the most compact options available, though their write speeds can be inconsistent during heavy lifting.
Performance-wise, the SanDisk Extreme V2 is close to the Samsung T9 on a standard 10Gbps port; it is half the weight of the T9 and offers better water resistance for travel. However, SanDisk’s recent reliability history means buyers must take a bit of a leap of faith.
The Samsung T7 is a solid all-rounder although its post-cache write speed lags behind the T9. Given that both drives retail within $15 of each other ($235 vs $250), the T9 is a better long-term investment for performance-oriented users.
Finally, Orico C10 offers a unique, lanyard-friendly design. Unlike Samsung and Sandisk, Orico sources its NAND from various suppliers, meaning internal components – and the resulting sustained performance – can be a hit-or-miss depending on the production batch.
The Current Trend
The portable SSD market in 2026 is defined by a paradox: technology has reached new heights while accessibility has plummeted. While USB 3.2 Gen 2×2 (20Gbps) is now the established performance floor and USB4 (40Gbps) is moving slowly into the mainstream, flash storage deals of the past are long gone. Industry-wide, we are currently navigating a historic price surge – often cited as the 2026 NAND Shortage – which has seen retail prices for popular models more than double since late last year.
Under the hood, USB 3.2 SSDs are now either NVMe-based SSDs paired with a PCIe to USB 3.2 Gen 2×1 bridge chip or native USB SSDs equipped with a direct NAND to USB 3.2 controller. Dual flash drives universally belong in the latter category, mainly because their reduced form factor requires an all-in-one solution that integrates SSD controller and USB bridge.
In real-world, our benchmark shows the latest batch of portable SSDs can easily handle heavy lifting with speeds of 700 to 800MB/s yet the external interface remains a bottleneck for PCIe Gen 3 NVMe drives. USB4 SSDs are obviously in a different league, pushing boundaries toward 38000MB/s by utilizing PCIe Gen4 x2 lanes, but until the NAND shortage eases, these high-bandwidth drives remain premium niche tools rather than standard consumer upgrades.

Native USB vs Bridged NVMe SSDs
Two types of drives based on bridge- and single chip-based SSDs were tested in this round-up. Bridge-based drives – Samsung T9, T7, Sandisk Extreme V2, and Orico C10 – contain a full NVMe SSD as well as a dedicated bridge and a separate NAND controller. Both the T7 and Extreme V2 utilize the ASMedia ASM2362 USB-to-PCIe x2 bridge with support for USB 3.2 Gen 2 (10Gbps), while the T9 steps up to the ASMedia ASM2364 to unlock the higher-bandwidth USB 3.2 Gen 2×2 (20Gbps) protocol. The C10 incorporates the Realtek RTL9210 – a popular USB-to-M.2 SSD bridge found in DIY enclosures.
On the flip side, single chip-based drives integrate a USB bridge and NAND controller into a single piece of silicon. Both Kingston XS2000 and XS1000 take this route by incorporating the Silicon Motion SM2320. The XS2000 – the pro-version of the two – differentiates with onboard USB 3.2 Gen 2×2 support . This all-in-one design approach allows for a significantly smaller physical footprint as well as reducing overall cost.
One quick reality check, though. Gen 2×2 (20Gbps) ports are still pretty rare. You won’t get that the full performance boost of an SSD that supports the dual-lane USB 3.2 mode unless your PC includes such a port. While 20Gbps ports are becoming common on enthusiast motherboards and high-end mini PCs, laptops have skipped them almost entirely in favor of USB4, which unfortunately defaults back to 10Gbps when connected to a Gen 2×2 drive.
Sequential Benchmarks
For the intended purpose of external SSDs, our focus was on sequential read and write performance as most users will primarily use these drives for moving large files.
Benchmark tests were carried out on Nodesoft’s DiskBench to compare read and write speeds between different USB 3.2 SSDs on a 2019 15-inch MacBook Pro. The port being used supports Thunderbolt 3 with USB 3.2 Gen 2×1 (10Gbps) compatibility. Our test files comprised a 40GB of MPEG-4 movie and 10GB of JPEG photos.
In terms of sequential read and write performance, all five external SSDs are fairly close. However, the Crucial X9 Pro, Kingston X2000, and ORICO C10 outperformed the Samsung T7 and SanDisk Extreme V2 by 7 to 17%, as the latter two are beginning to show their age. The difference is more profound in small file read operations, according to our benchmarks.
SLC Cache Stress Test
When it comes to flash storage devices, performance consistency is of paramount importance. These external SSDs only live up to their manufacturers’ claimed write speeds when files are written into the drives’ SLC cache. However, once the cache has been exhausted, incoming data goes directly into the native QLC or TLC area. For denser and slower NAND like QLC, this can wreak havoc on writing performance.
The size of the SLC cache varies from drive to drive. Even within the same model, larger capacity drives have proportionally larger allocations of cache than smaller ones. For that reason, it’s worth putting the SLC cache size and the post-cache write performance of these SSDs into comparison. For the purpose of this test, we copied a 400GB folder with an assortment of movie files ranging from 5 to 10GB to our 1TB SSDs. We continuously monitored for any irreversible trend of performance loss during the course of the transfers. The results are organized in the table below.
| Kingston XS1000 SSD | Kingston XS2000 SSD | Orico C10 SSD | Samsung T7 SSD | Samsung T9 SSD | Sandisk Extreme V2 SSD |
|
|---|---|---|---|---|---|---|
| SLC Cache Size: | 100GB | 96GB | 30GB | 40GB | 23GB | 13GB |
| Post-cache Native Flash Write Speed: USB 3.2 2x1 (10Gbps) | 100MB/s | 300MB/s (during partial recovery) 60MB/s (lowest) | 300 to 360MB/s | 380 to 420MB/s | 560MB/s (native TLC write matching USB interface speed) | 560MB/s |
| SLC Cache Write Speed: USB 3.2 2x1 (10Gbps) | 555MB/s | 550MB/s | 610MB/s | 525MB/s | 560MB/s | 580MB/s |
| Approximate Performance Loss (%) Beyond SLC Cache Limit: | 82% | 54 to 89% | 40 to 51% | 20 to 28% | N/A | 3.5% |
Crucial X9 Pro 1TB has a very impressive direct-to-TLC write speed. We dumped a 400GB folder filled with an assortment of video files and we didn’t see any dips in performance. Incidentally, Crucial has a non-Pro version of X9 that features QLC NAND and a fair amount of SLC cache. Even so, you can expect a sizable drop in performance during prolonged write sessions.
Kingston XS2000 began at 550MB/s until post-cache write fell to 60MB/s after the 96GB mark. Its SLC cache did make partial recovery because write speeds started picking again and eventually hit 300MB/s. However, the drive fell into another cache cliff after what appeared to be another cache saturation. The cycle repeated itself until the completion of the transfer.
Samsung T7 1TB was able to maintain around 525MB/s up to the 40GB mark. After that, there’s a noticeable drop in write performance to between 380 and 420MB/s. Sandisk Extreme V2 held its own against the Crucial X9 Pro as the post-cache write speed was well within acceptable ranges. It has a relatively small SLC cache followed by a steady direct-to-TLC write throughout the transfer process.
Build & Durability
Every drive featured here is compact enough to fit easily into a pocket. ORICO C10 makes a very distinctive impression; on one end of the drive features a large hanging hole that hooks the C10 securely to lanyards, backpacks, or keychains. Its unique design does make the drive a lot longer though.
Crucial X9 Pro is now much sleeker and lighter, marking a substantial 40% size reduction over the previous X8 model. This is all thanks to new internal design that leverages the Silicon Motion SM2320 single-chip solution. The X9 Pro now shares a similar footprint with an Apple AirPod Pro case. In fact, it is the second most compact USB 3.2 SSD tested here, with the Kingston XS2000 being even smaller. The XS2000 measures just 70 × 33 × 13.5mm.
As far as durability goes, Kingston XS2000 comes with a very reassuring rubber sleeve that wraps around the drive for drop protection while Sandisk Extreme V2 has a silicone coating that provides impact and scratch resistance. Not only will they survive a 2m drop, but also likely hold up without a dent or scratch. Our only gripe with Extreme V2 is the use of flimsy plastic on the front panel, which is certainly a weak spot structurally.
In comparison, Samsung T7 with its aluminum unibody case feels very durable on hand. The SSD is tested for drops of up to 2m; however, dropping it onto a hard surface will surely leave a dent in the body. The drive could use a silicone case or bumper that helps to hold up to everyday wear and tear. Crucial X9 is enclosed in an anodized matte aluminum body with its back coated with a thin layer of rubber. Solid construction combined with shock absorbers ensures data survivability in case the drive is dropped (up to 2m) or stepped on.
SSDs in general are pretty resilient to drops but they are still vulnerable to splash and dust. Crucial X9, Kingston XS2000, Sandisk Extreme V2, and Samsung T7 are rated for IP55 so they have been tested for dust- and splash-proof – to a certain extent.
