The 4TB Tier Is Now the Best Value — By a Lot
There’s a value inversion happening across all three capacity tiers this week, and it’s more dramatic than usual. The cheapest per-GB price at 1TB is currently around $0.146/GB. At 2TB you can beat that, and at 4TB the gap widens further. The 4TB NVMe tracker median sits at $594.98 with the floor at $459.99.
The standout here is the WD Blue SN5000 4TB, which holds the best per-GB price across the entire 287-drive dataset. It’s currently $489.00, carries a 4.7 rating from nearly 2,800 reviews, and 200 people bought it last month. For a mainstream Gen 4 drive with solid credentials, that’s the benchmark everyone else is chasing.

If you’re debating whether to buy 1TB now and upgrade later versus going straight to 4TB: the math increasingly favors 4TB. The 1TB market median is $189.99 and there’s less room to negotiate. The 2TB tier median is $329.00 — still a reasonable option, but the per-GB advantage shrinks compared to 4TB.
Gen 5’s Premium Is Collapsing — Down to 12.35%
Six months ago, Gen 5 carried a meaningful premium over Gen 4. This week that gap is 12.35% on average per GB. For most gaming workloads, that premium buys you bandwidth you can’t fully use — game load times between Gen 4 and Gen 5 remain nearly identical in real-world tests.
The interesting play this week is the Samsung 9100 PRO 2TB, which at $398.95 is moving 3,000 units a month — making it the third most-purchased drive in the entire dataset. That kind of volume from a Gen 5 drive suggests buyers are warming up to the generation in a way we haven’t seen before.
For 4TB Gen 5, the Crucial T705 4TB took the biggest drop of the week among Gen 5 drives — down $10.60 in seven days — and now sits at $639.99. It’s a well-reviewed TLC drive (1,400 reviews, 4.7 rating) and currently competes on price with some Gen 4 alternatives at the same capacity. If you want Gen 5 with a proven track record, this is the one to watch. See our Best Gen 5 NVMe picks for context.
This Week’s Price Movers
Biggest drop: The BIWIN Black Opal NV7400 4TB fell $24.50 in seven days, now at $489.99. It’s a 7,450 MB/s read drive with 888 reviews and a 4.7 rating — genuinely competitive in the 4TB space. Worth a look if you’re price-sensitive but don’t want to go completely unknown.
Biggest spike: The Sandisk Optimus GX 7100 2TB jumped $50 in a week and is now at check current price. That’s a 12.5% increase with no obvious justification — the drive has only 80 reviews and had 100 people buy it last month. Avoid until it settles. There are better 2TB options at that price point.
Crucial P310 1TB: Up $16.70 in one day, now at $187.99. Still one of the most-bought 1TB drives with 11,000 reviews and 1,000 monthly buyers, but that single-day jump is unusual and may correct. Also worth noting: the 2230 version of the Crucial P310 2TB rose $16.40 over the past week as well — at $369.00 it’s pricier than the 2280 version but essential for Steam Deck and ROG Ally users.
What’s Actually Selling
Samsung continues to dominate purchase volume. The Samsung 990 PRO 2TB is the top seller site-wide with 6,000 units bought last month. At $389.99 it’s not the cheapest 2TB, but the brand trust is real.
The Kingston NV3 1TB remains the Amazon’s Choice pick and is moving 4,000 units a month at $159.77 — it also dipped $2.80 today, making it one of the better budget 1TB options right now. For budget-conscious buyers, also check our Best Budget NVMe guide.
WD_BLACK is surprisingly strong in the purchase data — the WD_BLACK SN7100 1TB at $199.00 has 2,000 monthly buyers and a 4.8 rating from 6,400 reviews. That’s a legitimately excellent 1TB Gen 4 drive that doesn’t get as much attention as Samsung equivalents.

Listings to Be Cautious About
A few patterns worth flagging:
SUNEAST 1TB shows as the cheapest 1TB per-GB at $149.99, but it has only 5 reviews and zero purchase data. The price is eye-catching, but there’s essentially no track record here. Pass unless you’re feeling adventurous.
KOOTION 2TB jumped 17% in seven days to check current price with 9 reviews total. A drive going up in price while having almost no review history is a red flag, not a deal.
Corsair MP700 Elite 4TB Gen 5 has a “Save 17%” badge and dropped $10.70 this week to $699.99, but it only has 3 reviews. The 9,400 MB/s read speed is real, but at that price with essentially no user data, established alternatives are safer. Check our Best Gen 4 NVMe guide for proven alternatives at lower price points.
Multi-pack alert: The Samsung 990 PRO 4TB 2-Pack listing is showing up in the 4TB category data and is distorting the top end. It’s not a single drive — don’t compare its price to standard single-unit listings.
The PS5 Upgrade Market Remains Overcrowded
The Best NVMe for PS5 category is flooded. This week the Sandisk Optimus GX PRO 850P lineup landed with officially licensed PS5 branding and a heatsink included — but at check current price for 2TB, it’s the most expensive 2TB drive tracked. Only 5 reviews. Premium for the badge, not the performance.
For PS5 buyers who want a heatsink included without the brand tax, there are multiple options in the $260–300 range from Fanxiang, Vansuny, and Crucial P310 that do the same job. The WD_Black SN7100 2TB at $329.99 has 1,000 monthly buyers and a 4.8 rating from 6,400 reviews — arguably the most trustworthy 2TB option right now if you don’t need a heatsink included.
