An external SSD is a pocket-sized drive that plugs in by USB-C and moves large files much faster than a hard drive. We put three 1TB drives from Samsung, SanDisk and PNY side by side on read and write speed, size, weight, durability and warranty, all in the roughly 2,000 MB/s class.
How We Chose
We compared one 1TB drive each from Samsung, SanDisk and PNY, all with a listed read speed of about 2,000 MB/s. They are not identical: the Samsung and the PNY list USB 3.2 Gen 2×2, while SanDisk’s page does not state the interface, and the PNY page’s specification table shows the 2TB model. Speeds are the maximum figures the manufacturers publish and real transfers depend on your computer’s port and the files. We take specs from each manufacturer’s page where it gave one, and each cell names its source. Warranty terms come from the manufacturer’s own website where it names the model or product line, then from the Amazon listing, and we say so where neither gave a length. Prices are Amazon prices checked in October 2026 and can change.

Samsung T9 Portable SSD 1TB (MU-PG1T0B)
$241.97 as of Oct 19, 2026, 9:49 pm CT on Amazon · fastest write speed
Best for: buyers who want the fastest write speed here (1,950 MB/s) and a 5 year warranty.
We like the T9 for its write speed. Samsung’s datasheet for the 1TB MU-PG1T0B lists a USB 3.2 Gen 2×2 (20Gbps) interface, up to 2,000 MB/s sequential read and up to 1,950 MB/s sequential write, AES 256-bit hardware encryption, drop resistance up to 3 m, and a five-year limited warranty. Samsung notes that the weight may vary by capacity, and that physical damage is not covered by the warranty.
Warranty: 5 years limited

$243.53 as of Oct 19, 2026, 9:49 pm CT on Amazon · smallest and lightest, IP65
Best for: buyers who want the smallest and lightest drive here (46.9 g) with an IP65 rating.
We like the SanDisk Extreme for its size and weather resistance. SanDisk’s page for SDSSDE70-1T00-G25 lists up to 2000 MB/s read and 1700 MB/s write, 256-bit AES password protection, an IP65 rating with up to 3 m of drop protection, a USB-C to USB-C cable in the box, and a 5-year limited warranty. The page does not state the interface standard.
Warranty: 5 years limited
Check Price on Amazon →PNY RP60 1TB Portable SSD
$192.43 as of Oct 19, 2026, 9:49 pm CT on Amazon · lowest price
Best for: buyers who want a USB 3.2 Gen 2×2 drive with an IP65 rating at the lowest price here.
We like the PNY RP60 as the lowest price option in this speed class. PNY’s page lists a USB 3.2 Gen 2×2 interface, 2,000 MB/s read and 1,800 MB/s write, an IP65 rating and drop resistance up to 3 m. The page’s specification table shows the 2TB model, and it gives no weight, so the weight comes from the Amazon listing. PNY’s page also mentions both a lifetime warranty and a 3-year warranty, but PNY’s SSD warranty document lists the RP60 1TB at 3 years or 750 TBW, whichever comes first, so we use that.
Warranty: 3 years or 750 TBW
Check Price on Amazon →Our Take
We would start with the Samsung T9 at $241.97 if you want the fastest write speed here and a 5 year warranty. We would pick the SanDisk Extreme at $243.53 if size and weather resistance matter most: it lists 46.9 g and an IP65 rating. The PNY RP60 at $192.43 is the lowest price here and a fair fit if you do not need the longer warranty, since PNY lists 3 years or 750 TBW. Drive speeds also depend on a matching USB-C port on your computer, so check yours first.

Frequently Asked Questions
What is the best external SSD overall?
We would start with the Samsung T9 for most people: it lists the fastest write speed here (1,950 MB/s) and a 5 year warranty on Samsung’s datasheet. We like the SanDisk Extreme as the smallest and lightest drive, and the PNY RP60 as the lowest price option.
Do I need USB 3.2 Gen 2×2 to get full speed?
The 2,000 MB/s class speeds these drives list need a fast USB-C port. Samsung and PNY list USB 3.2 Gen 2×2 (20Gbps), and a slower port will limit transfers. We suggest you check which USB standard your computer supports before you buy.
How long is the warranty on these external SSDs?
We take these from the manufacturers: Samsung and SanDisk both list a five-year limited warranty, and PNY’s SSD warranty document lists 3 years or 750 TBW for the RP60 1TB, whichever comes first. Terms can differ by seller and region, so we suggest you confirm before you buy.
Are these drives water and dust resistant?
SanDisk and PNY both list an IP65 rating, and all three list drop resistance up to 3 m. Samsung’s datasheet lists the drop resistance but no water or dust rating for the T9, so treat it as drop resistant only.
