Samsung 870 EVO 1 TB SATA III – 2.5″ SSD – Full Description
Premium SATA SSD with Exceptional Reliability
The Samsung 870 EVO 1 TB (model MZ‑77E1T0B/AM or MZ‑77E1T0E) offers premium SATA III performance with proven longevity. Powered by Samsung’s MKX controller and 128-layer V‑NAND TLC- backed by a 5-year warranty- it stands among the most reliable SSDs in its class.
Industry-Leading Speeds with TurboWrite
Sequential read and write speeds reach up to 560 MB/s read and 530 MB/s write—maximizing the SATA III interface. The drive includes a variable TurboWrite buffer (≈42 GB) to sustain high performance during burst writes.
Responsive Random Performance
Delivers strong random performance: ~98-000 IOPS for reads and ~88-000 IOPS for writes- ensuring fast OS boot- app launch- and multitasking responsiveness. Testing has consistently confirmed this headroom.
Endurance for Peace of Mind
Rated for 600 TBW (Total Bytes Written)- which translates to 0.3 drive writes per day (DWPD) over five years under normal workloads.
Low Power & Broad Compatibility
Consumes around 0.03 W idle- roughly 2.2 W average- and peaks at 3.5 W- making it energy efficient. The standard 2.5″ × 7 mm form factor fits virtually all laptops and desktops using SATA. Samsung Magician software adds firmware updates- cloning- health monitoring- and optimization tools.
Frequently Asked Questions
Q: How does the 1 TB version differ from smaller 870 EVO models?
A: It includes 1 GB LPDDR4 cache- higher TurboWrite tolerance- and endurance of 600 TBW- compared to 150 TBW (250 GB) and 300 TBW (500 GB).
Q: Will write speeds drop after the TurboWrite buffer fills?
A: Yes- sustained write speeds may slow to around 300 MB/s once the 42 GB buffer is exhausted—but still faster than HDDs or older SSDs.
Q: Can it be used with macOS or Linux?
A: Yes. The SATA interface ensures plug-and-play compatibility across Windows- macOS- and Linux. Magician software is Windows-only.
Q: How does it compare to NVMe SSDs?
A: While limited by the SATA interface- the 870 EVO stands as the fastest SATA SSD available. NVMe drives exceed its speeds- but 870 EVO remains widely compatible with older systems.
Q: Why choose it over competitors like Crucial MX500?
A: It offers nearly double endurance—600 TBW vs 360 TBW for the MX500 1TB—and tight system integration with Samsung’s software ecosystem.
