Quick answer: Buy the Samsung T9 for most jobs. It is the faster drive, and on Amazon AU right now it is also the cheaper one at both 1TB and 2TB, which turns the usual "T7 Shield is the value pick" assumption on its head. The T9 2TB is the standout for price per gigabyte. Choose the T7 Shield only when you need its ruggedness: IP65 dust and water resistance, a rubberised body and a 3-metre drop rating for worksites, travel and rough handling. One catch on the T9: its 2,000MB/s speed needs a USB 3.2 Gen 2x2 port, and most laptops and all Macs do not have one.

Four Samsung portable SSDs, ranked by a repair shop that does its own data recovery.

What to look for in a portable SSD

Solid state, not spinning. This guide contains zero hard drives, and that is deliberate. A portable spinning hard drive has read heads floating microns above spinning platters. Drop it or knock it while it is running and the heads can strike the surface, scoring the platters and taking the data with them. In the data recovery work we do, dropped and knocked portable hard drives are one of the jobs we get most. For anything that leaves a desk, solid state is the only kind of drive we will put our name on. No moving parts means nothing to crash when it hits the floor.

Interface and real-world speed. The headline MB/s number on the box only happens if your computer has the matching port. This is the fact that most changes the decision here, and a lot of reviews mention it only in passing, so there is a whole section on it below. Read it before you pay for speed you cannot use.

Ruggedness. If the drive is going to a worksite, on the road, on a shoot, or into a kid's bag, an IP rating and a drop rating are worth real money. If it lives between a desk and a laptop sleeve, they are not.

Capacity and price per gigabyte. The bigger drive is almost always better value per gigabyte, and running an SSD near full slows it down and wears it faster. Buy more than you think you need today.

The four picks, ranked

Prices below are the figures on amazon.com.au at the time of writing, checked 10 July 2026. Treat them as a snapshot: the Amazon buybox moves week to week, so tap through to check the live price before you buy. The recommendation logic holds even if the numbers shift, and here is why. The T9 is never the slower drive, and on a machine without a Gen 2x2 port the two run at the same speed, so the T9 only has to be price-competitive to be the better buy. Right now it is actually cheaper. If a sale flips that, check the live prices on the buttons and pick the T7 Shield only when you need its ruggedness.

Side-by-side comparison

The one spec that decides it: does your computer even support Gen 2x2?

Here is the fact that should drive your choice, and the one most reviews skate past. The T9's headline 2,000MB/s only happens over USB 3.2 Gen 2x2, a 20Gbps interface. Gen 2x2 is genuinely rare. Most Windows laptops ship with USB 3.2 Gen 2 at 10Gbps, not Gen 2x2, and no Mac supports Gen 2x2.

The part that catches people out: Thunderbolt and USB4 ports do not support Gen 2x2 either. They are faster interfaces in their own right, but Gen 2x2 is a separate USB mode they do not implement. So plugging a T9 into a Thunderbolt Mac or a USB4 laptop still runs it at Gen 2 speed, around 1,050MB/s. To actually see 2,000MB/s you need a machine or an add-in card with an explicit Gen 2x2 port, which in practice means a minority of Windows desktops and laptops. A two-minute check settles it: on Windows, open Device Manager, expand Universal Serial Bus controllers, and look for one listed as USB 3.2 Gen 2x2 or 20Gbps; if you only see 10Gbps or Gen 2, you are on Gen 2. On a Mac, hold Option, open the Apple menu and choose System Information, then look under USB and Thunderbolt; you will find Thunderbolt or USB4, never Gen 2x2.

Why this matters for the buying decision: if your machine has no Gen 2x2 port, the T9 and the T7 Shield run at almost exactly the same speed. At that point the speed sheet is a tie, and you choose on the two things that actually differ: price and ruggedness. That is the whole game. Buy the T9 for the sharper price and the T7 Shield for protection, and stop paying attention to the 2,000MB/s number unless you have checked that your port can use it.

How to use a portable SSD properly

• Do not run it near full. An SSD kept close to capacity slows down and wears faster. Leave headroom, which is another reason to size up.
• Eject before you unplug. Pulling a drive mid-write is a classic way to corrupt files, and we get the fallout in the shop. Use the safe-eject step every time.
• Use the supplied cable, or a rated one. A cheap or damaged cable can drop you to a slower USB mode, or drop the connection entirely mid-transfer.
• Do not treat it as your only copy. It is a fast working drive or the copy you carry, not a backup on its own. More on that next.

What I see at the bench: why this guide has no hard drives

iFix runs a data recovery bench, and it shapes how I think about portable storage. The single most common portable-drive job we get is a dropped or knocked spinning hard drive. The physics are unforgiving: a hard drive reads with heads hovering a fraction of a hair's width above platters spinning thousands of times a minute. A knock while it is running lets the heads touch down, and once they score the platter surface, the data underneath is often gone for good. That is why, for anything that leaves a desk, I only recommend solid state. No platters, no heads, nothing to crash on impact.

Solid state is far tougher, but it is not immortal. Here is the part the box will not tell you. SSDs fail too, and when they do it is often sudden and total: the controller gives up and the whole drive drops offline at once, with none of the clicking or gradual bad-sector warning a dying hard drive gives. SSD recovery is genuinely harder and less predictable than hard drive recovery for that reason. So the ruggedness of a T7 Shield protects you from the drop that kills a spinning drive, but nothing protects you from a controller that simply dies one morning. One more thing we tell anyone who brings in a locked drive: both of these Samsung drives use AES 256-bit hardware encryption, so if you set a password and lose it, the data is gone. That is not a recovery job, it is a locked door with no key. Store the password as carefully as the drive.

Which is why one drive is never a backup. The fix is not a tougher single drive, it is a second copy. Follow 3-2-1: three copies, on two types of media, one kept off-site. A portable SSD is a superb fast working copy or the drive you carry between places, but keep another copy somewhere else. If you want the fixed side of that plan, a small home NAS is the natural partner, and we cover those in our home NAS and backup guide.

If a drive does fail, stop. The worst thing you can do with a drive that has died or is misbehaving is keep plugging it in and hoping. Repeated power cycling can turn a recoverable situation into a lost one. Power it down, stop writing to it, and bring it in. Our data recovery service exists for exactly these cases, and the sooner a failed drive reaches us, the better the odds.

So which Samsung SSD should you buy?

• You want the best value and the most storage. Samsung T9 2TB. Fastest ceiling, best value per gigabyte, and at current AU pricing it undercuts the rugged 2TB drive.
• You want a fast everyday drive and do not need 2TB. Samsung T9 1TB. Same speed, lower price, and cheaper than the rugged 1TB right now.
• Your drive lives a hard life and you need 2TB. Samsung T7 Shield 2TB. IP65, 3-metre drop rating, room for large files. Buy it for the armour.
• You want ruggedness but only need 1TB. Samsung T7 Shield 1TB. The compact knockabout drive for field kits.
• No Gen 2x2 port? The T9 and T7 Shield perform almost identically, so decide purely on price and whether you need the ruggedness.
