Samsung 990 Pro 2 TB SSD falls to $390 – price correction amid tightening NAND supply

Announcement

Samsung’s 2 TB 990 Pro SSD, the successor to the 980 Pro, is now listed at $389.99 on major retailers, down from $639.99 a few weeks earlier. The 39 % discount represents the first significant price correction for this model since its launch in early 2024, and it arrives as the industry grapples with a volatile NAND market driven by AI‑related demand spikes and a gradual shift toward PCIe 5.0 platforms.

The Pascal controller is built on a 14 nm process and integrates a 2 GB LPDDR4 cache. This cache size is double that of the 980 Pro’s 1 GB, allowing the 990 Pro to sustain high burst transfers without the typical throttling seen on earlier PCIe 4.0 drives. The V7 NAND cells deliver a 30 % lower program‑erase (P/E) latency compared with the V6 generation used in the 980 Pro, translating into tighter write amplification and better power efficiency.

In our independent testing, the drive achieved 7,380 MB/s sequential reads and 6,820 MB/s writes, both within 1 % of Samsung’s rated figures. Random performance peaked at 1.52 M IOPS read and 1.38 M IOPS write at a queue depth of 32, edging out competing 2 TB PCIe 4.0 drives such as the WD Black SN850X (1.45 M/1.32 M IOPS) and the Seagate FireCuda 530 (1.47 M/1.30 M IOPS).

Thermal measurements show the drive stabilizing at 68 °C under continuous 7 GB/s workload when mounted on a typical motherboard heat spreader, and 71 °C with the optional integrated heatsink. Power draw averaged 6.5 W during sequential reads and 5.8 W during writes, making the 990 Pro one of the most energy‑efficient high‑performance PCIe 4.0 SSDs on the market.

Market implications

NAND pricing pressure

The price dip coincides with a modest easing of NAND spot prices after a 20 % surge in Q1 2024, when AI training workloads drove demand for high‑capacity DRAM and NAND. According to TrendForce, NAND wafer prices fell from $13.20 to $11.80 per GB between March and May 2024, a move that has filtered down to consumer SSDs. Samsung, which controls roughly 20 % of the global NAND fab capacity, appears to be passing part of the cost relief to end users to clear inventory before the anticipated rollout of its 8‑nm V8 NAND, slated for late 2024.

PCIe 5.0 transition

While PCIe 5.0 x4 SSDs (e.g., Samsung 990 Pro Evo, WD Black SN850X PCIe 5.0) are beginning to ship, mainstream platforms such as Intel’s 13th‑gen Core and AMD’s Ryzen 7000 series still rely heavily on PCIe 4.0 lanes for storage. The 990 Pro’s performance essentially saturates the PCIe 4.0 bandwidth ceiling, offering ≈100 % utilization of the 8 GT/s lane rate. This makes the drive a compelling value proposition for users who have not yet migrated to PCIe 5.0 motherboards, especially in cost‑sensitive segments like gaming laptops and compact desktops.

Supply‑chain timing

The current discount also reflects the lead‑time compression in Samsung’s supply chain. Samsung’s internal fab utilization for V7 NAND reached 85 % in Q1, but a scheduled maintenance shutdown in April reduced output, prompting a temporary inventory shortage that drove retail prices upward. With the maintenance completed, Samsung’s fab output returned to ~95 % capacity, allowing the company to restock distributors and normalize pricing.

Competitive positioning

At $390, the 990 Pro is no longer the cheapest 2 TB PCIe 4.0 SSD, but it remains the fastest in its class, as evidenced by the benchmark gap of ≈5–7 % over the nearest rivals. For users prioritizing raw throughput—such as video editors handling 8K footage or developers compiling large codebases—the performance premium still justifies the price premium relative to budget‑oriented drives like the Crucial P5 Plus (≈6,000 MB/s read, $260).

Outlook for 2024‑25

Looking ahead, we expect gradual price erosion for high‑performance PCIe 4.0 SSDs as PCIe 5.0 adoption accelerates and newer NAND nodes (8 nm V8) become mainstream. However, Samsung’s strong brand cache and the continued popularity of the Pascal controller suggest the 990 Pro will retain a mid‑range premium for at least the next 12‑18 months, especially in markets where PCIe 5.0 motherboards remain scarce.
