概要
The 30-Second Version
The SanDisk Extreme PRO 4TB is a rugged, fast, and expensive portable SSD that earns its price only if you actually need the durability. For desk jockeys, it's overkill.
Pros & Cons
長所
- Rugged as hell: 3-meter drop protection and IP65 water/dust resistance 93rd
- Sustained 2000 MB/s speeds without throttling, even on huge transfers 68th
- Hardware encryption keeps your files locked down
- 5-year warranty shows SanDisk actually trusts this thing
短所
- DRAM-less design feels cheap for a drive this expensive
- You need a USB 3.2 Gen 2x2 port to hit rated speeds, and most laptops don't have one
- Price is brutal compared to internal NVMe drives with the same capacity
- Feature set is thin for the money

実証データ
Performance
The 2000 MB/s read and write speeds are legit, but only if your machine has a USB 3.2 Gen 2x2 port. Plug this into a regular USB-C or older USB 3.0 port and you'll see half that, or worse. What surprised us is how well it holds up under sustained load. Multiple owners report transferring 500GB+ without any thermal throttling, which is exactly what that forged aluminum heatsink is for. It's DRAM-less, which usually makes us nervous, but the real-world sustained performance here is better than most DRAM-less drives we've tested.

vs Competition
The Samsung 9100 PRO and Kingston FURY Renegade G5 both offer similar or better raw speed in a smaller, cheaper package, but they don't have the drop protection or IP65 rating. The Crucial T500 is the budget pick if you just want fast storage and don't care about durability. If you're a photographer or videographer working in the field, the Extreme PRO's ruggedness justifies the price. If you're just backing up files at a desk, get the Crucial and save your money.

Value & Pricing
This drive is expensive, no way around it. In Canada, prices swing from CAD 800 to CAD 993 depending on the vendor, and that's a huge spread for the exact same drive. If you're buying in Canada, shop around because the cheapest listing is nearly CAD 200 less than the priciest one. You're paying for the rugged build and the SanDisk name, not raw performance. For most people, a cheaper external SSD or even a good internal NVMe in an enclosure makes more sense.

詳細情報
Overview
The SanDisk Extreme PRO 4TB is the portable SSD you buy when you're done messing around with flimsy drives that die after one drop. It's built like a tank, pushes 2000 MB/s reads and writes, and has a 5-year warranty to back it up. The one thing to know? You're paying a serious premium for that ruggedness, and you need a USB 3.2 Gen 2x2 port to actually hit those speeds.
Common Questions
Q: Why am I only getting 1000 MB/s instead of 2000 MB/s?
Your computer probably doesn't have a USB 3.2 Gen 2x2 port. Most laptops and desktops top out at 10Gbps USB 3.2 Gen 2, which caps around 1000 MB/s. Check your port specs before blaming the drive.
Q: Is this drive good for gaming?
Yeah, actually. People run games like Arma Reforger directly off it without issues. Load times will be a bit slower than an internal NVMe, but it's totally playable for most titles.
Q: Does the hardware encryption slow it down?
Not that we've seen. The AES 256-bit encryption is handled in hardware, so there's no meaningful performance hit when it's enabled.
Who Should Skip This
If you're just looking for fast external storage to keep on your desk, this isn't it. Go grab a Crucial T500 or a solid NVMe drive in a cheap enclosure instead. You'll get the same or better speeds for way less money, and you won't be paying for drop protection you'll never need.
Verdict
Buy this if you need a portable drive that can survive a fall off a table, a splash of rain, and a 500GB file transfer without breaking a sweat. It's the best rugged external SSD we've tested, and the sustained performance is genuinely impressive. But if you're not shooting in the field or traveling with your data, you're overpaying for protection you'll never use.
