Samsung 860 PRO SSD 4TB

Bottom line: The Samsung 860 PRO SSD 4TB ($1934.45 on Amazon as of 2026-10-07): MLC V-NAND instead of TLC - built for sustained writes, not just burst speed; main trade-off: SATA III caps it at 560MB/s - NVMe drives are several times faster.

Pros & Cons

Pros

  • ✓ MLC V-NAND instead of TLC - built for sustained writes, not just burst speed
  • ✓ 4TB in one 2.5-inch bay, no M.2 slot or heatsink clearance needed
  • ✓ 560MB/s read and 530MB/s write saturates the SATA III interface
  • ✓ Runs on Windows 7/8, Server 2003, Vista SP1+, XP SP2+, macOS and Linux, 32- and 64-bit

Cons

  • ✗ SATA III caps it at 560MB/s - NVMe drives are several times faster
  • ✗ Highest cost-per-TB tier; 860 EVO gives the same interface speed for less
  • ✗ Windows 10 and 11 are not named in the stated compatibility list
  • ✗ 0-70 C operating range is narrower than industrial-rated drives

Manufacturer description

The Samsung 860 PRO 4TB is the top-capacity model in Samsung's MLC-based SATA line, built around V-NAND and an algorithm-driven controller aimed at sustained rather than burst workloads. Sequential reads reach up to 560MB/s and writes up to 530MB/s, which is effectively the ceiling of the SATA III interface -- so the value here is not peak speed but how consistently the drive holds it. Samsung positions the 860 PRO for high-end PCs, workstations, and NAS enclosures where heavy multitasking and long write sessions are routine, which is why it uses MLC V-NAND instead of the cheaper TLC found…

SpecPicks Verdict

SpecPicks scored Samsung 860 PRO SSD 4TB 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 860 PRO 4TB?

Samsung rates it at sequential read speeds up to 560MB/s and sequential write speeds up to 530MB/s. That is essentially the maximum the SATA III interface allows, so expect similar figures from any quality SATA SSD.

Is the 860 PRO faster than an NVMe SSD?

No. The 860 PRO is a SATA III drive rated up to 560MB/s read, while NVMe drives use the PCIe bus and run several times faster. Choose the 860 PRO when you need a 2.5-inch SATA bay filled, not maximum throughput.

What is the difference between the 860 PRO and the 860 EVO?

The 860 PRO uses MLC V-NAND, which Samsung positions for the heavy sustained workloads of high-end PCs, workstations, and NAS units. The EVO line uses TLC. Both share the same SATA III interface, so peak sequential speeds are similar.

Will the 860 PRO work with my operating system?

Samsung lists Windows 8, Windows 7, Windows Server 2003, Vista (SP1 and above), and XP (SP2 and above) in both 32-bit and 64-bit, plus macOS and Linux. Newer Windows releases are not named in that list -- check the product listing for current OS support.

Can I use the 860 PRO in a NAS?

Samsung specifically names NAS units alongside high-end PCs and workstations as target systems, citing consistent speeds under heavy workloads and multitasking. Operating temperature range is 0 to 70 degrees C, so confirm your enclosure stays inside that window.
