# Samsung 990 EVO Plus 2TB efficient mid-range SSD (2026)

The Samsung 990 EVO Plus 2TB offers 7,200 MB/s sequential reads over a hybrid PCIe 5.0 x2 or PCIe 4.0 x4 interface, paired with Samsung's 236-layer V-NAND and 1,200 TBW endurance.

Quick answer: The Samsung 990 EVO Plus 2TB is a solid choice for gamers and general users who want reliable NVMe speed at a reasonable price. Its 7,200 MB/s reads, low power draw, and 1,200 TBW endurance cover most non-professional workloads well. The DRAM-less design means it falls behind drives with dedicated DRAM under sustained random writes, so professional content creators should consider the Samsung 990 Pro 2TB instead. For everyone else, the 990 EVO Plus 2TB offers a practical balance of speed, efficiency, and Samsung's proven brand reliability at a competitive price. The five-year warranty and Samsung Magician software support round out a complete package for mainstream NVMe storage.

## Performance

Samsung rates the 990 EVO Plus 2TB at 7,200 MB/s sequential read and 6,300 MB/s sequential write, matching the 1 TB and 4 TB models across the lineup. Random performance reaches 1,000,000 read IOPS and 1,400,000 write IOPS. These IOPS figures are consistent across all three capacities.

The 2 TB model has more NAND die than the 1 TB, which improves sustained write performance after the TurboWrite SLC cache fills. Native TLC writes on the 2 TB model are faster than on the 1 TB because the additional die allow the controller to distribute writes across more physical flash targets. Burst performance is identical, with the TurboWrite cache absorbing incoming writes at full speed until its allocation is exhausted.

HMB uses 32 to 64 MB of system RAM, which has minimal impact on system performance. Active power draw is around 5.5 W, making the 990 EVO Plus one of the most power-efficient NVMe drives at this performance level. The low power draw also means the drive runs cool enough to operate without a heatsink in most desktop configurations.

## Endurance, TBW & Warranty

Samsung covers the 990 EVO Plus 2TB with a five-year limited warranty and a 1,200 TBW endurance rating. At 1,200 terabytes written, the drive supports approximately 658 GB of daily writes over the five-year period. Writing 50 GB per day would consume only about eight percent of the endurance over five years, meaning the drive will easily outlast the warranty. Samsung Magician software tracks TBW usage, firmware version, and drive health, giving users full visibility into remaining write budget and helping plan for future replacements. This level of endurance is comparable to drives with dedicated DRAM, making the EVO Plus 2TB suitable for users with moderate write demands.

## Pros and Cons

**Pros:**

- 7,200 MB/s sequential read speed
- 1,200 TBW endurance with five-year warranty
- Hybrid PCIe 5.0 x2 / PCIe 4.0 x4 interface
- Low power draw around 5.5W
- 236-layer V8 TLC NAND for efficiency
- Better sustained writes than 1TB model
**Cons:**

- DRAM-less, uses HMB from system RAM
- Write speed trails Samsung 990 Pro
- Only x2 lanes on PCIe 5.0
- Not ideal for sustained random write workloads
- No included heatsink


## Verdict

The Samsung 990 EVO Plus 2TB is a solid choice for gamers and general users who want reliable NVMe speed at a reasonable price. Its 7,200 MB/s reads, low power draw, and 1,200 TBW endurance cover most non-professional workloads well. The DRAM-less design means it falls behind drives with dedicated DRAM under sustained random writes, so professional content creators should consider the Samsung 990 Pro 2TB instead.

## Frequently Asked Questions

### Is the Samsung 990 EVO Plus 2TB good for gaming?

Yes. The 990 EVO Plus 2TB delivers 7,200 MB/s reads and 6,300 MB/s writes, which is well above what most games require. Game load times are comparable to higher-end drives since most games are limited by queue depth and file fragmentation rather than sequential speed. The 2 TB capacity fits a large game library with room for other files.

### Does the Samsung 990 EVO Plus 2TB have DRAM?

No. The 990 EVO Plus is a DRAM-less design that uses Host Memory Buffer (HMB) to borrow 32 to 64 MB of system RAM for the flash translation layer. This works well for gaming and general use but adds a small latency penalty under heavy sustained random writes compared to drives with dedicated DRAM.

### What is the endurance of the Samsung 990 EVO Plus 2TB?

The 2 TB model carries a 1,200 TBW endurance rating. This is double the 1 TB model's 600 TBW. Writing 50 GB daily would take roughly 65 years to reach the rated endurance limit. Most users will never approach this threshold during the five-year warranty period. Samsung Magician software lets you monitor TBW consumption in real time.

### Does the Samsung 990 EVO Plus 2TB work on both PCIe 4.0 and 5.0?

Yes. The 990 EVO Plus has a hybrid interface that runs as PCIe 5.0 x2 on Gen5 motherboards or PCIe 4.0 x4 on Gen4 systems. Both configurations deliver the same 7,200 MB/s rated speed since two Gen5 lanes provide similar bandwidth to four Gen4 lanes. The drive automatically negotiates the best available mode.

### How does the 990 EVO Plus compare to the Lexar NM790?

Yes. The drive exceeds Sony's PS5 M.2 SSD requirements: it runs as a PCIe 4.0 x4 NVMe with reads well above 5,500 MB/s and fits the 110 x 25 x 11.25 mm slot constraint. No heatsink is included, but the drive runs cool enough that a thin aftermarket heatsink or the PS5's integrated cooling cover is sufficient for reliable operation during extended gaming sessions.

### Is the Samsung 990 EVO Plus 2TB compatible with PS5?

Yes. The drive exceeds Sony's PS5 M.2 SSD requirements: it runs as a PCIe 4.0 x4 NVMe with reads well above 5,500 MB/s and fits the 110 x 25 x 11.25 mm slot constraint. No heatsink is included, but the drive runs cool enough that a thin aftermarket heatsink or the PS5's integrated cooling cover is sufficient for reliable operation.
