Samsung 850 PRO - 1TB - 2.5-Inch SATA III Internal SSD (MZ-7KE1T0BW)

Bottom line: The Samsung 850 PRO ($170.00 on Amazon as of 2026-10-06): 550 MB/s read and 520 MB/s write, near the SATA III ceiling; main trade-off: SATA III caps it far below NVMe drives in the same price range.

Manufacturer description

The Samsung 850 PRO 1TB is a 2.5-inch SATA III internal SSD (MZ-7KE1T0BW) built for people who push storage hard. Samsung rates it at sequential reads up to 550 MB/s and writes up to 520 MB/s, with random performance reaching 100,000 read IOPS and 90,000 write IOPS, so boot times drop to as little as 15 seconds and large project files open without the stall you get from a spinning drive. Driving it is Samsung's 5th-generation 3-core MEX controller paired with 3D V-NAND, a combination Samsung positions for sustained throughput rather than short bursts. Endurance is the headline: a 150TBW…

SpecPicks Verdict

SpecPicks scored Samsung 850 PRO using a rating × review-volume × price-fit model applied to published specs and reviews across the ssds & storage category. Samsung's ssds & storage lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for ssds & storage of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.

Frequently Asked Questions

How fast is the Samsung 850 PRO 1TB?

Samsung rates it at up to 550 MB/s sequential read and 520 MB/s sequential write, with random performance up to 100,000 read IOPS and 90,000 write IOPS. Samsung says it can boot a system in as little as 15 seconds.

What warranty does the 850 PRO come with?

Samsung backs it with a 10-year limited warranty and a 150TBW endurance rating. Check the product listing for current warranty terms and registration requirements in your region.

Will this SSD work in my laptop?

It is a standard 2.5-inch SATA III drive, so it fits any laptop or desktop with a 2.5-inch SATA bay. Desktop 3.5-inch bays need an adapter bracket, which is not always included.

Does the 850 PRO support hardware encryption?

Yes. It supports AES 256-bit encryption and is compatible with Microsoft BitLocker and the TCG/Opal 2.0 standard, so you can enable full-drive encryption without a software performance penalty.

Is the 850 PRO worth it compared to an NVMe SSD?

Only if your system is SATA-only. SATA III limits it to roughly 550 MB/s no matter what, so on a motherboard with a free M.2 NVMe slot you will see substantially higher sequential speeds elsewhere.
