SAMSUNG

Samsung 870 QVO 4TB 2.5" SATA internal SSD

SKU CH-E0K7-48PEX

A 4 TB 2.5" SATA SSD with up to 560 MB/s read and 530 MB/s write speeds for desktop or laptop storage upgrades

  • Massive 4 TB capacity stores huge media libraries
  • Sequential reads up to 560 MB/s over SATA
  • Sequential writes up to 530 MB/s over SATA
  • 13 % faster random reads than 860 QVO
  • 21 % higher sustained write speed than 860 QVO

4TB SATA QLC SSD

The Samsung 870 QVO is a 2.5-inch internal solid-state drive that uses a SATA III interface and second-generation QLC flash. It is intended for everyday PC users, creators and IT professionals who want a large-capacity upgrade for a desktop or laptop without moving to a faster but pricier interface. The four-terabyte model sits in a lineup that also includes 1TB, 2TB and 8TB versions.

Sustained write behaviour

Intelligent TurboWrite employs a larger variable buffer to keep write speeds high during long transfers, and the manufacturer states sustained write performance is improved by up to 21 percent over the previous model. Sequential read and write reach up to 560 and 530 MB/s respectively, while random read at queue depth one is up to 13 percent faster. Endurance is rated at 360 TBW for this capacity, backed by a refined error-correcting code algorithm.

Build and connectivity

The drive uses the standard 2.5-inch form factor with a SATA data and power connector, so it fits typical drive bays and caddies in both desktops and laptops. No additional mounting hardware or cables are mentioned in the supplied data. Reliability is doubled to 2,880 TBW for the range-topping model, and the product carries a three-year limited warranty from the manufacturer.

Questions sur cet article

How much power does the Samsung 870 QVO 4TB draw during all-day operation?

The 870 QVO uses the SATA interface with sequential speeds up to 560 MB/s read and 530 MB/s write; SATA SSDs typically consume only a few watts under load and milliwatts at idle, so heat and noise remain negligible in a desktop or laptop.

What existing hardware is required for the Samsung 870 QVO 4TB to function?

You need a 2.5-inch drive bay or caddy and a free SATA data plus power connector; the drive works with any system that supports SATA III, including the test platform with a Core i7-7700K at 4.20 GHz and DDR4 1200 MHz memory.

Will the Samsung 870 QVO 4TB work reliably alongside an older SATA SSD such as an 860 QVO?

Yes, both drives use the same SATA interface; the 870 QVO delivers up to 13 percent faster random read and 21 percent better sustained write than the 860 QVO, so mixed workloads run smoothly without bottlenecks.
