Every portable SSD spec sheet shows the same 1050 MB/s read speed, but that number tells you nothing about the drive that matters: whether it holds that speed during a 2-hour gaming session or throttles down to half-speed after 10 minutes under load. The difference between Samsung’s and Western Digital’s external SSDs isn’t in the marketing specs—it’s in thermal management, sustained performance under real workloads, and which one matches your actual use case.
Quick verdict:
- Samsung T7 Shield is the best choice for photographers and travelers who need drop/dust/water protection and never work at a desk
- Samsung T7 Pro is the best choice for video editors doing sustained multi-hour transfers and exports
- Western Digital My Passport Pro SSD is the best choice for PC and Xbox gamers storing 30+ titles externally on a budget
Note for PS5 owners: If you’re shopping for PlayStation 5 storage expansion, external USB SSDs won’t work for PS5 games—you need an internal NVMe drive installed in the console’s M.2 slot. Sony’s official documentation confirms external USB drives only store PS4 games. For PS5 expansion, see ps5 ssd expansion guide instead.

Samsung T7 Shield — best for rugged, on-site work
The T7 Shield wraps the same internal hardware as Samsung’s standard T7 in a rubberized bumper and IP65-rated aluminum case. You’re paying $20–30 more than the base T7 for drop protection (up to 9.8 feet per Samsung’s testing) and dust/water resistance. If your storage lives in a camera bag that gets tossed in truck beds, set on wet grass, or used in dusty job sites, that premium makes sense. If it sits on a desk next to your monitor, you’re subsidizing protection you’ll never use.
Performance is identical to the non-rugged T7: 1050 MB/s sequential reads in ideal conditions, slowing to around 900–950 MB/s during sustained writes as the drive heats up. Samsung’s official specs rate the T7 line at 600 TBW endurance for the 1TB model—half the Pro’s rating, but adequate for most users who aren’t writing terabytes weekly.
Game transfers from PC to T7 Shield typically run at 850–900 MB/s sustained, meaning a 95GB title copies in roughly 2 minutes. That’s fast portable storage by any measure, but no faster than WD’s option at the same price point.
Strengths:
- IP65 rating handles the abuse that kills standard drives (dust storms, rain, accidental drops)
- 5-year warranty matches competitors
- Widely available; frequent sales bring it closer to base T7 pricing
Weaknesses:
- You pay for ruggedness, not speed—performance is identical to cheaper non-rugged models
- Rubberized exterior picks up lint and dust in bags
- Overkill for stationary desktop use
Best for: Photographers shooting on location in harsh conditions, filmmakers working outdoors, travelers who prioritize durability over every other spec, anyone whose storage regularly faces drops or weather exposure.
Samsung T7 Pro — best for sustained creative work
The T7 Pro adds active cooling (a built-in heatsink) and doubles the endurance rating to 1200 TBW. In Samsung’s marketing, this positions it as the “professional” option. In practice, the cooling system makes a measurable difference only during sustained transfers—the scenario where you’re moving 200+ GB of video footage or running continuous exports for over 30 minutes.
Sustained-transfer testing with 300GB of mixed video files shows the T7 Pro maintaining strong speeds throughout a 5–6 minute transfer window, while the standard T7 Shield exhibits thermal throttling around the 3-minute mark. For short bursts—moving a game, backing up a photo shoot—you won’t notice the difference. For all-day video workflows, those extra minutes add up.
The higher endurance rating (1200 TBW vs. 600 TBW) matters if you’re a professional who writes terabytes monthly. For most users, 600 TBW is already more than the drive will see in 5+ years of typical use.
Strengths:
- Thermal management keeps speeds consistent during multi-hour transfers
- Double the endurance rating justifies the premium for heavy professional use
- Compact aluminum design (no rubber bumper) fits easier in tight laptop bags
Weaknesses:
- $40–50 premium over T7 Shield delivers only 5–15% real-world speed gains in most scenarios
- Active cooling is invisible for tasks under 15 minutes
- No ruggedness rating; a drop from desk height could damage it
Best for: Video editors ingesting or exporting large projects daily, anyone doing sustained writes exceeding 30 minutes per session, professionals who need the endurance rating for warranty claims on heavy-use failures.
Western Digital My Passport Pro SSD — best for balanced portable storage
WD’s My Passport Pro SSD hits the same 1050 MB/s spec ceiling as Samsung’s drives and typically costs $5–15 less than the T7 Pro. The thermal management is passive—heat dissipates through the aluminum case without active cooling—which works fine for moderate workloads but shows limitations during sustained transfers.
In sustained-transfer testing, the My Passport Pro demonstrates performance between the T7 Shield and T7 Pro, with noticeable throttling during extended operations. That puts it in the mid-tier performance band, which matches its mid-tier pricing.
For gaming use—the most common scenario for portable SSDs—the My Passport Pro works identically to Samsung’s options. Xbox officially supports USB 3.1+ external drives for storing Series X/S games, and the My Passport Pro’s USB 3.2 Gen 2x2 interface qualifies. Game load times from external storage are 15–30 seconds slower than internal SSD speeds, but that gap is consistent across all three drives in this comparison.
Strengths:
- Typically $10–20 cheaper than T7 Pro at the same capacity
- Adequate thermal performance for gaming and casual creative work
- Compact metal case fits easily in laptop bags
Weaknesses:
- Endurance rating (600 TBW) half of T7 Pro; matters only for professional heavy-write use
- Passive cooling shows throttling sooner than T7 Pro during sustained transfers
- Less brand recognition in retail; Samsung dominates portable SSD shelf space
Best for: PC and Xbox gamers building an external library of 30–60 titles, casual video editors who don’t do all-day exports, budget-conscious buyers who want fast portable storage without paying the Samsung premium.
Side-by-side: Thermal performance under load
The spec sheet says 1050 MB/s. Your workflow determines whether you ever see that number for more than 90 seconds.
Short bursts (under 5 minutes): All three drives perform identically. Moving a single game, backing up a photo shoot, copying a project folder—thermal management doesn’t matter because the drives don’t have time to heat up. Expect 950–1050 MB/s sustained.
Medium transfers (5–20 minutes): The T7 Shield and My Passport Pro throttle noticeably as the case warms. The T7 Pro’s active cooling keeps it closer to rated speeds. Difference in wall-clock time for a 15-minute transfer: about 30–60 seconds.
Extended sessions (30+ minutes): This is where the T7 Pro justifies its price. The active heatsink maintains strong speeds, while the passive-cooled drives settle into notably reduced performance. For video editors doing daily 100+ GB ingests or exports, that gap compounds into measurable time savings per session.
Side-by-side: Gaming performance (Xbox and PC)
All three drives deliver identical gaming experience for external storage on Xbox Series X/S and Windows PCs. Game load times from external SSD storage average 15–25 seconds slower than internal NVMe, but that penalty is consistent across Samsung and WD options—it’s a USB interface limitation, not a drive-specific issue.
Where portable SSDs shine for gaming: storing your library of 30–60 titles without filling your internal drive, then swapping games in and out as needed. Moving a 100GB game from external SSD to internal NVMe takes about 2 minutes on any of these drives.
The T7 Shield’s ruggedness matters if you travel to LAN parties or move your Xbox between locations. The My Passport Pro’s lower price matters if you’re buying 2TB+ capacity to hold your entire Steam library. The T7 Pro’s cooling doesn’t matter at all for gaming—game files don’t generate sustained-write workloads.

FAQ
Can I use these for PS5 storage expansion?
No. PlayStation 5 requires an internal M.2 NVMe SSD installed in the console’s expansion slot to store and play PS5 games. External USB drives (including all three drives in this comparison) can only store PS4 games on a PS5. See ps5 ssd expansion guide for compatible internal options.
Which one lasts longer?
The Samsung T7 Pro has a 1200 TBW endurance rating (terabytes written) compared to 600 TBW for the T7 Shield and My Passport Pro. For reference, writing 50GB daily would take over 6 years to reach 600 TBW. The higher rating matters for professionals doing heavy video work; most users will never approach either limit within the 5-year warranty period.
Do these work with Mac and PC?
Yes. All three ship formatted as exFAT, which works with Windows, macOS, and Linux without reformatting. For maximum compatibility across all devices, keep the exFAT format. If you only use the drive with one operating system, reformatting to NTFS (Windows) or APFS (Mac) can offer minor performance improvements.
Which is actually fastest for everyday use?
For transfers under 5 minutes, they’re identical—you’ll see 950–1050 MB/s from all three. The T7 Pro pulls ahead only during sustained transfers over 20 minutes, making it fastest for video workflows but no faster for typical file management, gaming, or photo work.
