# Samsung 990 EVO Plus 4TB capacity-focused SSD (2026)

The Samsung 990 EVO Plus 4TB is the largest capacity in the EVO Plus lineup, offering 7,200 MB/s sequential reads with 2,400 TBW endurance for users who need bulk NVMe storage at mid-range pricing.

Quick answer: The Samsung 990 EVO Plus 4TB is a strong option for users who need a large, fast NVMe drive without paying the premium for a DRAM-equipped flagship. Its 7,200 MB/s reads, 2,400 TBW endurance, and TLC NAND give it an edge over QLC-based 4 TB alternatives from other brands. The main limitation is the DRAM-less design, which means sustained random writes trail drives like the Samsung 990 Pro 4TB with dedicated DRAM. For gaming, media storage, and general productivity at 4 TB, the EVO Plus delivers reliable performance at a competitive price point. Samsung's five-year warranty and Magician software support provide additional peace of mind for long-term storage investments.

## Performance

Samsung rates the 990 EVO Plus 4TB at 7,200 MB/s sequential read and 6,300 MB/s sequential write, identical to the 1 TB and 2 TB models across the lineup. Random performance reaches 1,000,000 read IOPS and 1,400,000 write IOPS, also matching the smaller capacities.

The 4 TB model's performance advantage emerges in sustained write scenarios. With more NAND die to distribute writes across, native TLC write speeds are higher than the 1 TB model once the TurboWrite SLC cache fills. The larger SLC cache allocation on the 4 TB also means longer burst write windows before throttling occurs, which benefits users moving large files or working with video content.

The DRAM-less HMB design keeps power consumption around 5.5 W, impressively low for a 4 TB drive. The drive is single-sided, fitting standard M.2 2280 slots without clearance issues. In PCIe 4.0 x4 mode the drive delivers its full rated speed, so users without PCIe 5.0 motherboards can still get maximum performance without compromise.

## Endurance, TBW & Warranty

Samsung covers the 990 EVO Plus 4TB with a five-year limited warranty and a 2,400 TBW endurance rating. At 2,400 terabytes written, the drive can handle approximately 1.3 TB of daily writes over the five-year warranty period. Writing 100 GB per day would consume only about eight percent of the endurance over five years, giving the drive a very long service life for most workloads. Samsung Magician software provides real-time TBW monitoring and health status, giving professional users the data they need to plan drive replacement cycles. This endurance rating is generous for a mid-range drive and reflects the durability advantages of TLC NAND over QLC alternatives.

## Pros and Cons

**Pros:**

- 7,200 MB/s sequential read speed
- 4TB capacity with TLC NAND
- 2,400 TBW endurance with five-year warranty
- Low 5.5W active power consumption
- Hybrid PCIe 5.0 x2 / PCIe 4.0 x4 interface
- Single-sided M.2 2280 design
- Samsung Magician software support
**Cons:**

- DRAM-less, uses HMB from system RAM
- Write speed trails DRAM-equipped drives
- Only x2 lanes on PCIe 5.0
- Higher cost than QLC-based 4TB alternatives
- Not ideal for heavy random write workloads


## Verdict

The Samsung 990 EVO Plus 4TB is a strong option for users who need a large, fast NVMe drive without paying the premium for a DRAM-equipped flagship. Its 7,200 MB/s reads, 2,400 TBW endurance, and TLC NAND give it an edge over QLC-based 4 TB alternatives from other brands. The main limitation is the DRAM-less design, which means sustained random writes trail drives like the Samsung 990 Pro 4TB with dedicated DRAM.

Samsung's five-year warranty and Magician software support provide additional peace of mind for long-term storage investments.

## Frequently Asked Questions

### How does the Samsung 990 EVO Plus 4TB compare to QLC drives?

The 990 EVO Plus uses TLC NAND, which is faster and more durable than QLC flash found in budget 4 TB drives like the Crucial P3 Plus. TLC maintains better sustained write speeds and has higher endurance ratings per GB. The trade-off is a higher cost per GB compared to QLC alternatives, but the performance and longevity benefits justify the premium for most users.

### What is the endurance of the Samsung 990 EVO Plus 4TB?

The 4 TB model is rated at 2,400 TBW (terabytes written). This is double the 2 TB model's 1,200 TBW and quadruple the 1 TB's 600 TBW. Writing 100 GB per day would take roughly 65 years to exhaust the rated endurance. Samsung Magician software tracks TBW usage in real time and provides alerts as the drive approaches its endurance threshold.

### Is the Samsung 990 EVO Plus 4TB good for PS5?

Yes. The drive meets Sony's PS5 M.2 expansion requirements as a PCIe 4.0 x4 NVMe drive exceeding 5,500 MB/s reads. The single-sided M.2 2280 design fits within the 110 x 25 x 11.25 mm slot constraint with a compatible heatsink. The 4 TB capacity can hold a very large game library, making it ideal for PS5 users with extensive digital collections.

### Does the Samsung 990 EVO Plus 4TB have DRAM?

No. The 990 EVO Plus is DRAM-less and uses Host Memory Buffer (HMB) to borrow system RAM for the flash translation layer. This design choice keeps cost and power consumption low. For sustained professional write workloads, the Samsung 990 Pro 4TB with dedicated DRAM would be a better choice, but for gaming and general use the HMB approach works well.

### Can the Samsung 990 EVO Plus 4TB be used in a laptop?

Yes, as long as the laptop has an M.2 2280 NVMe slot. The drive is single-sided and draws only about 5.5 W, making it compatible with most modern thin-and-light and gaming laptops. However, verify your laptop supports drives larger than 2 TB, as some older BIOS implementations have capacity limits that prevent the full 4 TB from being recognized.

### What NAND does the Samsung 990 EVO Plus use?

The 990 EVO Plus uses Samsung's eighth-generation 236-layer V8 TLC (three-level cell) V-NAND flash memory. This is a newer and denser generation than the 133-layer NAND used in the original Samsung 990 EVO, enabling better efficiency, improved sustained write speeds, and the 4 TB capacity option that the older flash generation could not support.
