Five brands sell portable SSDs with the same USB-C connector and different interface wording. Samsung and Kingston label their drives USB 3.2 Gen 2 with speeds up to 1,050MB/s. Lexar labels the Armor 700 USB 3.2 Gen 2×2 with up to 2,000MB/s. SanDisk and Crucial print 2,000MB/s and 2,100MB/s read figures, and none of the six lists USB4 or Thunderbolt.
The six drives below are compared by the interface each maker or Amazon listing states, the speed it rates, and the protection it lists. Five are 1TB listings and the Lexar is a 2TB listing, so read this page for the interface wording, not for how much each drive holds.
Compare the interface wording first, then the read and write ratings, then the water, dust and drop figures.Portable SSDs Compared by Interface

1. Samsung T7 Portable SSD — Best Simple USB 3.2 Gen 2 Pick
Samsung rates the T7 at up to 1,050MB/s read and 1,000MB/s write over USB 3.2 Gen 2, on its US product page and in the Amazon bullets. The Amazon bullets credit PCIe NVMe technology and call the speed almost twice that of the Samsung T5. The Amazon listing is the 1TB Titan Gray model, MU-PC1T0T, and the bullets say the line goes up to 4TB.
Samsung’s bullets describe a solid aluminum unibody with shock resistance and fall protection up to 6 feet. They also say the drive can record 4K 60fps video directly with a camera or mobile device, and that it supports iPhone 15 Pro ProRes 4K at 60fps. The bullets give no IP rating.
Pick the T7 for fall protection up to 6 feet when no water or dust rating is needed.Our Take Samsung’s T7 is the simplest drive here, with one stated interface, one speed pair and a fall figure. Choose it over the T7 Shield when the drive stays in a bag or on a desk and a water rating adds nothing.
- Samsung states USB 3.2 Gen 2 with up to 1,050MB/s read and 1,000MB/s write, a single interface and speed pair to compare with a laptop port.
- Samsung describes a solid aluminum unibody for the T7 and gives fall protection up to 6 feet.
- Samsung says the T7 can record 4K 60fps video directly with a camera or mobile device.
- Samsung’s T7 bullets give no IP water or dust rating, and the T7 Shield adds an IP rating for buyers who need one.
- Samsung rates the T7 at up to 1,050MB/s read, below the 2,000MB/s to 2,100MB/s read figures for the SanDisk, Lexar and Crucial drives.
2. Samsung T7 Shield Portable SSD — Best Rugged USB 3.2 Gen 2 Pick
Samsung’s US page for the 1TB T7 Shield lists USB 3.2 Gen 2, up to 1,050MB/s read and 1,000MB/s write, an IP65 rating and a drop figure of up to 9.8 feet. The Amazon title and bullets match, so the Shield keeps the T7’s speed pair and adds the water, dust and drop figures.
The Amazon bullets add that Samsung Magician software monitors drive health and sets LED color combinations. They list PC, Mac, Android and gaming consoles, and iPhone 15 Pro ProRes 4K at 60fps video with the included cable recommended. The listing is the black 1TB model, MU-PE1T0S/AM, and the bullets give a range of 1TB to 4TB.
Pick the Shield for IP65 and 9.8 feet. The interface and speed match the T7.Our Take Samsung’s T7 Shield suits a drive that travels through rain, dust or rough handling. Choose the standard T7 instead when those ratings solve no problem.
- Samsung states an IP65 rating for water and dust resistance.
- Samsung states fall protection up to 9.8 feet, against 6 feet for the standard T7.
- Samsung’s bullets name Samsung Magician software, which monitors drive health and sets LED color combinations.

3. SanDisk Extreme Portable SSD — Best for Password Encryption
SanDisk’s product page rates the 1TB Extreme at up to 2,000MB/s read and up to 1,700MB/s write, with IP65 water and dust resistance, up to 3-meter drop protection and 256-bit AES encryption with password protection. SanDisk’s page does not name an interface. The Amazon title says USB-C 3.2 Gen 2.
Samsung and Kingston rate their USB 3.2 Gen 2 drives at up to 1,050MB/s read, so the title’s Gen 2 wording sits beside a 2,000MB/s figure that those two makers’ Gen 2 ratings do not reach. SanDisk’s page adds that performance may be lower depending on the host device, interface and usage conditions. The Amazon listing is the black 1TB model, SDSSDE70-1T00-G25.
Our Take SanDisk’s Extreme is the drive to pick here when password encryption and a 3-meter drop figure count alongside a 2,000MB/s read rating. Do not pick it for USB4 or Thunderbolt, because neither SanDisk’s page nor the Amazon listing names either.
- SanDisk rates the Extreme at up to 2,000MB/s read and up to 1,700MB/s write.
- SanDisk lists IP65 water and dust resistance with up to 3-meter drop protection.

Crucial rates the X10 at sequential reads up to 2,100MB/s, the highest read figure in this comparison, and the Amazon title adds USB 3.2 USB-C. Crucial’s page says the speed is its measured maximum sequential performance on a high-performance desktop computer with CrystalDiskMark, and that your performance may vary.
Crucial’s page lists IP65 dust and water resistance and drop resistance up to 9.8 feet (3 meters), and says the drive works with Windows, Mac, Android, iPad, PC and Linux through the included USB-C cable. The Amazon bullets add USB-A connections, Chromebooks, PS4, PS5 and Xbox, and three months of Mylio Photos Plus and Acronis True Image after registration. The Amazon listing is the blue 1TB model, CT1000X10SSD9-02, and Crucial’s page says the line goes up to 8TB.
Pick the X10 for the highest read rating here, with IP65 and a 9.8-foot drop figure.Our Take Crucial’s X10 is the drive to pick when the read rating and a USB-A connection both count. Crucial and the Amazon listing give no write speed for it, and neither names Gen 2×2, USB4 or Thunderbolt.
- Crucial rates the X10 at sequential reads up to 2,100MB/s.
- Crucial states IP65 resistance and drop resistance up to 9.8 feet (3 meters).

Kingston’s page lists a USB Type-C to Type-A cable and a Type-A to Type-C adapter in the box, and compatibility with Windows, macOS, Linux, Chrome OS, Android and iOS or iPadOS. Its comparison table marks the XS1000 “No” for an IP rating. The Amazon listing is the red 1TB model, SXS1000R/1000G, and Kingston’s page offers 1TB and 2TB.
Pick the XS1000R for a 28.7g drive with a cable and an adapter in the box.Our Take Kingston’s XS1000R is the small, light option with the same 1,050MB/s read rating as the Samsung T7. Choose it when weight and size count for more than water or drop ratings, which Kingston does not list.

The Amazon bullets add a thermal control design and Apple ProRes recording to the drive in up to 4K 60FPS with iPhone 15 Pro and iPhone 15 Pro Max, with a magnetic ring sold separately. Lexar’s page gives the line’s weight as 80g.
Pick the Armor 700 for a stated Gen 2×2 interface and IP66, with 2,000MB/s write as well as read.Our Take Lexar’s Armor 700 is the drive here with a Gen 2×2 label, an IP66 rating and a matching 2,000MB/s write figure. Neither Lexar’s page nor the Amazon listing names USB4 or Thunderbolt for it.
- Lexar states USB 3.2 Gen2x2 with up to 2,000MB/s read and 2,000MB/s write.

Buying Guide
1. Read the interface wording before the connector
Every drive here uses a USB-C connector, and the makers print different interface wording. Samsung’s T7 and T7 Shield pages and Kingston’s XS1000 page state USB 3.2 Gen 2 with up to 1,050MB/s read. Lexar’s page states USB 3.2 Gen2x2 with up to 2,000MB/s read and write. The Amazon titles for the SanDisk Extreme and Crucial X10 say USB-C 3.2 Gen 2 and USB 3.2 USB-C.
Among these six, only the Lexar states Gen 2×2, and none states USB4 or Thunderbolt. Compare the laptop’s port specification with the wording above before you buy. The portable SSD guide covers the wider category, and USB4 external SSDs for photographers and USB4 external SSDs for PC gaming cover drives whose listings state that interface.
2. Read each speed as a rated ceiling, for read or for write
Each figure is a maker’s or listing’s maximum. Samsung and Kingston rate 1,050MB/s read and 1,000MB/s write, SanDisk rates 2,000MB/s read and 1,700MB/s write, Crucial rates 2,100MB/s read, and Lexar rates 2,000MB/s read and write. Crucial says it measured its figure on a high-performance desktop computer, and SanDisk says performance may be lower depending on the host device, interface and usage conditions.
Compare read with read and write with write. Crucial gives no write speed, so its 2,100MB/s read figure has no matching write figure to compare. Lexar is the drive here with equal read and write ratings.
3. Compare the protection figures as stated
Three drives state IP65, one states IP66, and two state no rating. Samsung’s T7 Shield, SanDisk’s Extreme and Crucial’s X10 state IP65, and Lexar’s Armor 700 states IP66. The Samsung T7 bullets and Kingston’s comparison table list no IP rating for the T7 and XS1000.
Drop figures differ too. Samsung states 6 feet for the T7 and 9.8 feet for the T7 Shield, Crucial states 9.8 feet (3 meters), and SanDisk and Lexar state 3 meters. Kingston and the Amazon bullets give the XS1000 no drop figure. Match the number to the bag, desk or field the drive will see.
4. Check what each listing says the drive records and connects to
Recording to the drive is stated for three models. Samsung’s bullets say the T7 records 4K 60fps video directly with a camera or mobile device, and both Samsung drives list iPhone 15 Pro ProRes 4K at 60fps. Lexar’s Amazon bullets list ProRes recording with iPhone 15 Pro and iPhone 15 Pro Max. The SanDisk, Crucial and Kingston sources state no recording feature.
Device lists differ. Crucial’s Amazon bullets name Chromebooks, iPad Pro, PS4, PS5 and Xbox, and Kingston’s page names Windows, macOS, Linux, Chrome OS, Android and iOS or iPadOS. Crucial’s page adds that compatibility may vary with device formatting and host capabilities. Check the phone, camera or console maker’s storage requirements before relying on a list.
5. Note the capacity each listing covers
Five listings are 1TB and the Lexar is 2TB. The Samsung T7 and T7 Shield, SanDisk Extreme, Crucial X10 and Kingston XS1000R listings used here are 1TB models, and the Lexar Armor 700 listing is 2TB. Samsung’s bullets give 4TB as the top T7 size, Crucial’s page goes to 8TB, Kingston’s page stops at 2TB, and Lexar’s page goes to 8TB.
Pick the interface first, then the size. Once the interface wording fits the laptop, choose the capacity from the maker’s own range for that drive.
FAQ
Does a USB-C SSD reach its advertised speed on every laptop?
Not necessarily. SanDisk’s page says performance may be lower depending on the host device, interface and usage conditions, and Crucial’s page says your performance may vary from its desktop measurement. Each speed on this page is the maker’s or listing’s maximum.
Compare the interface wording in the table with the laptop’s own port specification before you buy.
Which drive here has the strongest water and dust rating?
Lexar’s Armor 700 states IP66, the highest rating on this page. Samsung’s T7 Shield, SanDisk’s Extreme and Crucial’s X10 state IP65. The Samsung T7 and Kingston XS1000R list no IP rating.
Lexar also states 3-meter anti-drop protection, as do SanDisk and Crucial. Samsung states 9.8 feet for the T7 Shield and 6 feet for the T7.
Does any drive here state USB4 or Thunderbolt?
No. Samsung and Kingston state USB 3.2 Gen 2, Lexar states USB 3.2 Gen2x2, and the SanDisk and Crucial Amazon titles state USB-C 3.2 Gen 2 and USB 3.2 USB-C. None of the maker pages or Amazon listings names USB4 or Thunderbolt.
If USB4 or Thunderbolt is the requirement, use USB4 external SSDs for photographers or USB4 external SSDs for PC gaming, whose listings state it.
Why does the SanDisk Extreme list Gen 2 beside 2,000MB/s?
SanDisk’s page and the Amazon title disagree on what is stated. SanDisk’s page rates up to 2,000MB/s read and 1,700MB/s write and names no interface. The Amazon title adds USB-C 3.2 Gen 2, while Samsung and Kingston rate their USB 3.2 Gen 2 drives at 1,050MB/s read.
Treat the interface as unconfirmed for this listing and check the drive’s own documentation. Neither source states a reason for the gap.
Can a portable SSD record video from a phone or camera?
Only where the listing says so. Samsung’s bullets say the T7 records 4K 60fps video directly with a camera or mobile device, and both Samsung drives list iPhone 15 Pro ProRes 4K at 60fps. Lexar’s Amazon bullets list ProRes recording with iPhone 15 Pro and iPhone 15 Pro Max, with a magnetic ring sold separately.
The SanDisk, Crucial and Kingston sources state no recording feature. Check the phone or camera maker’s storage requirements for any drive.
