# Samsung 870 EVO 8 TB: SATA SSD with TLC NAND and Double Endurance
Samsung has released an 8-terabyte version of the 870 EVO SSD with SATA interface. The model retains the series specifications: sequential read speeds up to 560 MB/s, write speeds up to 530 MB/s, up to 98,000 IOPS on read and 88,000 IOPS on write. It uses TLC NAND, 8 GB LPDDR4 cache, and offers 4800 TBW endurance with a 5-year warranty. This is the first drive in the lineup to exceed 4 TB.
The new version has appeared on Samsung's sites in Germany and Singapore five years after the series launched in 2021. Initially available capacities were 250 GB, 500 GB, 1 TB, 2 TB, and 4 TB.
Technical Specifications and Evolution
The 870 EVO 8 TB doubles key parameters compared to the 4 TB model:
- Capacity: 8 TB vs. 4 TB.
- LPDDR4 cache: 8 GB vs. 4 GB.
- TBW: 4800 TB vs. 2400 TB.
Performance remains at SATA III levels: the interface limits prevent exceeding the stated speeds. The controller and NAND chips are identical to other EVO models, but the increased cache volume improves sustained performance under prolonged workloads.
| Characteristic | 870 EVO 4 TB | 870 EVO 8 TB |
|---------------|--------------|---------------|
| Read, MB/s | 560 | 560 |
| Write, MB/s | 530 | 530 |
| Read IOPS | 98 000 | 98 000 |
| Write IOPS | 88 000 | 88 000 |
| Cache | 4 GB | 8 GB |
| TBW | 2400 TB | 4800 TB |
Comparison with QVO and Positioning
Previously, 8 TB in 2.5-inch SATA format was offered in the 870 QVO series (2020) using QLC NAND. QLC delivers high density but falls short of TLC in write speeds and endurance. The shift to 8 TB with TLC in the 870 EVO boosts reliability for write-intensive tasks like databases, virtualization, and archiving.
TLC NAND in the EVO series ensures fewer errors and better performance in mixed workloads. For mid- and senior-level developers, this matters in scenarios where SATA is still preferred for compatibility with legacy systems or budget servers.
Pricing and Availability
In Europe, the starting price for the 870 EVO 8 TB is 1259 euros, while the 4 TB version starts at around 600 euros. Price per TB drops only slightly, but the doubled TBW justifies the investment for enterprise workloads. The model targets users who need massive capacity without switching to NVMe.
Advantages for IT Professionals:
- High TBW for long-term operation.
- Compatibility with SATA infrastructure.
- TLC over QLC for reliable performance.
Key Takeaways
- 870 EVO 8 TB is the first model in the series with TLC NAND at 8 TB capacity and 4800 TBW endurance.
- Cache boosted to 8 GB, with performance maxed out for SATA (560/530 MB/s).
- Launched five years after the lineup debuted, with prices starting at 1259 euros.
- Better alternative to QVO thanks to TLC for superior reliability.
- Ideal for legacy systems and high-write workloads.
