Gaming SSD prices doubled from their 2025 lows. AI datacenter demand exhausted global NAND supply before 2026 began, and prices haven’t recovered — TrendForce reported TLC NAND costs rising over 120% year-over-year, with no meaningful relief expected before late 2026. The WD_BLACK SN850X 2TB, which cost $129 six months ago, now lists at $439. At that price, paying $1 more for the SN8100 Gen 5 is the obvious call. The old “buy Gen 4 for gaming” advice is dead.
Quick Picks
- Best Overall: WD_BLACK SN8100 2TB — 14,900 MB/s, $440; same price as the SN850X Gen 4, double the bandwidth
- Best Value: Crucial T705 2TB — lowest $/GB on Gen 5, $400 for 2TB
- Most Accessible: WD_BLACK SN8100 1TB — full Gen 5 speeds at $284
Buying Guide
Gen 4 vs Gen 5 in May 2026
This had a clear answer six months ago: buy Gen 4. The SN850X delivered the same game load times as a Gen 5 drive at less than half the price. That calculus is dead.
The SN850X 2TB now costs $439. The SN8100 2TB costs $440. There is no reason to choose the slower drive unless you’re on a PCIe 4.0-only platform with no upgrade path.
For any builder on Intel 700-series or AMD Ryzen 9000 / AM5 with a PCIe 5.0 M.2 slot, Gen 5 is now the obvious default.
How the NAND Shortage Changes Your Strategy
NAND flash prices roughly doubled from 2025 sale lows. TrendForce projects tight supply through year-end. What this means practically:
- Don’t wait for a deal. Sale prices $50–$80 below current street rates are possible, but a return to $129 SN850X pricing isn’t happening in 2026.
- Buy capacity now. With 2TB drives at $284–$440 and 4TB drives approaching $700+, securing storage before another wave of price hikes makes sense.
- 1TB + secondary storage beats an overpriced Gen 4 2TB. The SN8100 1TB ($284) paired with a budget 2TB SATA drive (~$80–100) costs less than a single SN850X 2TB and gives you better primary performance.
Capacity
2TB remains the target for a primary gaming drive. Modern AAA titles average 80–120 GB installed; Call of Duty regularly ships at 150 GB+. A 1TB drive gets full after 8–10 games.
That said, 2TB Gen 5 now starts at $400. If that’s a stretch, the SN8100 1TB at $284 is a real option — just plan secondary storage for overflow.
Heatsinks
Gen 5 controllers run significantly hotter than Gen 4. Without active airflow or a motherboard heatsink cover, the SN8100 and T705 will throttle under sustained writes. Most X870E and Z890 boards include M.2 heatsink covers — use them. The T705 heatsink version (ASIN B0CTS93WML) is worth the ~$20 premium if your board doesn’t have one. Gen 4 drives like the SN850X run cooler and don’t require heatsinks in standard mid-tower builds.
Detailed Reviews
WD_BLACK SN8100 1TB — Best Budget Gen 5
WD_BLACK SN8100 1TB
The WD_BLACK SN8100 1TB is the most accessible entry into PCIe 5.0 performance in May 2026. At $284, it delivers the same 14,900 MB/s sequential read speed as the 2TB variant — WD uses identical controller and NAND architecture across the SN8100 lineup, with capacity as the only variable.
For builders on a Gen 5 platform who can’t justify $400+ on a 2TB drive right now, this is the right call. Full DirectStorage 2.0 readiness, WD’s best-in-class thermal design, and the same performance ceiling as any other Gen 5 drive on the market.
The 1TB capacity is the real constraint. Plan to pair it with a secondary drive for game overflow. An SN8100 1TB ($284) plus a budget 2TB SATA drive (~$80) totals ~$364 and outperforms a single SN850X 2TB ($439) on every metric that matters for gaming — at $75 less.
The drive runs under 70°C under sustained load in cases with decent airflow. Use your board’s M.2 heatsink cover if available.
Crucial T705 2TB — Best Value
Crucial T705 2TB
The Crucial T705 2TB became the best-value Gen 5 SSD in 2026 by surviving the NAND price spike better than its competition. At $400, it’s the cheapest PCIe 5.0 2TB drive available right now — $40 less than the SN8100 2TB and $99 less than the Samsung 9100 PRO.
The specs hold up at this price. 14,500 MB/s sequential reads use the Phison E26 controller with Micron 232-layer TLC NAND — no QLC compromises, no SLC cache cliff during large transfers. The T705 maintains consistent write speeds from byte one through the end of a large file copy, something budget QLC drives fail at after their cache fills.
The Phison E26 runs hot. Without a heatsink, expect throttling from 12,700 MB/s to ~9,000 MB/s after around 30GB of sustained writes in a warm case. The heatsink version (ASIN B0CTS93WML, ~$420) solves this and is still $20 less than the SN8100 2TB. If your board has an M.2 heatsink cover, the bare version at $400 is fine.
No bundled software, no RGB. If you want the most storage performance per dollar in May 2026, the T705 2TB is the answer.
WD_BLACK SN8100 2TB — Best Overall
WD_BLACK SN8100 2TB
The WD_BLACK SN8100 2TB leads every Gen 5 consumer benchmark that matters. Sequential reads hit 14,900 MB/s and — unlike first-generation Gen 5 drives that throttled under sustained load — the SN8100 sustains performance through extended transfers. Under a 50GB sequential write, the SN8100 averages over 10,000 MB/s continuously, no throttle dip, outpacing the T705 in sustained workloads.
The thermal design is the real differentiator. WD redesigned the controller heat path versus older Phison E26 drives, achieving lower peak temps without a bundled heatsink. In a mid-tower with standard airflow, it stays under 68°C under sustained load — the best passive thermal behavior of any Gen 5 drive currently available.
At $440 for 2TB, the SN8100 now costs exactly what the SN850X Gen 4 costs. If you have a PCIe 5.0 slot and $440 to spend, there’s no reason to choose the slower drive. The only skip scenario: a PCIe 4.0 platform where Gen 5 speeds are wasted anyway.
For pure gaming on a Gen 5 platform, this is the pick.
Samsung 9100 PRO 2TB — Premium Alternative
Samsung 9100 PRO 2TB
The Samsung 9100 PRO 2TB is technically excellent and overpriced for most gaming use cases. At $499, it costs $60 more than the SN8100 2TB for performance that’s within margin of error in game load time comparisons. Sequential reads reach 14,700 MB/s (vs. 14,900 on the SN8100), and sequential writes come in at 13,400 MB/s — slightly higher on Samsung’s spec sheet, though both max out available NAND bandwidth in real-world conditions.
Where the 9100 PRO earns its premium is long-term endurance. Samsung’s 8th-gen V-NAND achieves lower write amplification than Phison E26 or WD’s in-house controller, meaning individual NAND cells are stressed less per write cycle. For content creators writing 100+ GB daily through 4K exports, video renders, and game streaming capture, that endurance advantage compounds meaningfully over a 3–5 year ownership window.
For a gaming-focused desktop writing 50–100 GB per day at most, neither the 1,200 TBW rating here nor the equivalent ratings on competing drives will be exhausted within the warranty period. The $60 premium over the SN8100 isn’t justified for gaming alone.
Heatsink version (ASIN B0DX2FN49V, ~$20 more) is recommended for sustained workloads.
WD_BLACK SN850X 2TB — Gen 4 Legacy Pick
WD_BLACK SN850X 2TB
The WD_BLACK SN850X was the right gaming SSD recommendation for two years. At $129 for 2TB, it delivered the same in-game experience as any Gen 5 drive at less than half the cost. At $439, that argument is gone.
The SN850X delivers 7,300 MB/s sequential reads — fast enough to saturate DirectStorage 1.2 and within 0–2 seconds of any Gen 5 drive on typical game loads. Starfield loads in 9.2 seconds vs. 8.8 on the SN8100. Alan Wake 2 loads in 4.1 seconds vs. 3.9. For pure gaming, the gap is irrelevant.
The problem is exclusively the price. At $439, you’re paying Gen 5 money for Gen 4 performance. The SN850X still makes sense in three specific scenarios:
- PCIe 4.0-only platform — Intel 12th/13th gen, or AMD B450/B550/X570 where Gen 5 slots don’t exist
- PS5 expansion — specifically validated for PS5 with Game Mode 2.0 support
- Discounted pricing — if you find it under $300, the value math improves
At full retail $439, buy the SN8100 instead.

FAQ
Does PCIe 5.0 make games load faster?
Marginally. Compared to a good Gen 4 drive, Gen 5 saves 0–2 seconds per game load in titles using DirectStorage 1.2. Most of the load time bottleneck in current PC games is CPU-side decompression, not raw storage bandwidth. DirectStorage 2.0, appearing in 2026–2027 game releases, will use Gen 5 bandwidth more effectively for real-time asset streaming.
Should I buy 1TB or 2TB in 2026?
2TB if you can afford it. Current AAA titles average 80–120 GB installed; live-service games like Call of Duty regularly exceed 150 GB. A 1TB drive handles 8–10 games before you’re deleting installs. The SN8100 1TB at $284 is a reasonable compromise if you pair it with secondary bulk storage.
Do Gen 5 SSDs need a heatsink?
Yes, for sustained performance. PCIe 5.0 controllers throttle under sustained writes without airflow. Most X870E and Z890 boards include M.2 heatsink covers — use them. For the T705, the heatsink version (ASIN B0CTS93WML) is strongly recommended if your board lacks a cover. Gen 4 drives like the SN850X run cooler and are fine without heatsinks in typical mid-tower builds.
Are these SSDs compatible with PS5?
The WD_BLACK SN850X is specifically designed and validated for PS5 expansion with Game Mode 2.0 support. Gen 5 drives (SN8100, 9100 PRO, T705) are physically compatible with the PS5’s M.2 slot but operate at Gen 4 speeds — there’s no performance benefit to installing a Gen 5 drive in a PS5.
When will SSD prices drop?
TrendForce and DRAM Exchange don’t project meaningful consumer SSD price relief until late 2026 at the earliest, and a return to 2025 sale pricing is unlikely within the next 12–18 months. AI datacenter demand absorbed the majority of 2026 NAND production before the year began. If you need storage now, waiting is unlikely to pay off within a reasonable window.
The Bottom Line
The NAND shortage collapsed the Gen 4 value argument. When the WD_BLACK SN850X 2TB costs $439 and the WD_BLACK SN8100 2TB costs $440, there’s only one rational choice on a Gen 5 platform: buy Gen 5.
For most builders, the Crucial T705 2TB at $400 is the right call — lowest cost-per-GB on Gen 5, full TLC NAND, same gaming load times as anything faster. Builders who want the best sustained performance and thermal headroom should choose the WD_BLACK SN8100 2TB at $440. If the 2TB budget is a stretch, the SN8100 1TB at $284 paired with secondary SATA storage is the smartest entry into a PCIe 5.0 platform.
The Samsung 9100 PRO is technically excellent but overpriced at $499 for typical gaming use. The SN850X at $439 only makes sense on PCIe 4.0 platforms or for PS5 expansion — not at Gen 5 parity pricing.
