4TB Gaming SSD: Gen4 & Gen5, Live Prices

Updated 2026-09-16

What 4TB actually holds

Weighed against the publisher-stated install sizes on our capacity guide (Cyberpunk 2077 at ~70GB, Grand Theft Auto V at ~125GB, Starfield at ~125GB, Baldur's Gate 3 at ~150GB, and Call of Duty at ~161GB "at launch," per each publisher's own Steam store page): a 4TB drive holds all five of those example titles installed simultaneously, with roughly 3.4TB left over for the rest of your library. These are publisher figures, not measured by us, and real install sizes grow with patches and content updates - so treat this as a snapshot of today's numbers rather than a permanent ceiling.

Who 4TB suits

4TB fits all five of the example titles cited above with meaningful room left over, per the arithmetic above - enough headroom that a buyer with a genuinely large, actively-maintained library (a dozen or more mid-size titles, or several of the largest current games at once) stops needing to manage installs around free space at all.

A realistic scenario at 4TB

At 4TB, system overhead becomes a rounding error against the drive's total capacity - the publisher figures cited above show all five example titles fitting with several terabytes to spare. A realistic use case here is less about fitting a specific library and more about never thinking about free space at all, which is the actual value proposition at this tier rather than any specific title count.

How 4TB compares to the capacity next door

4TB is priced for buyers who have already decided 2TB isn't enough headroom - the per-gigabyte rate at this tier is usually close to 2TB's, per our live data, rather than a fresh premium, which is why the decision between the two tiers usually comes down to library size rather than price efficiency. See the live $/TB ladder on our capacity guide for today's exact crossover.

The same-money note

The cheapest Gen5 drive at 4TB costs $223.01 more than the cheapest Gen4 drive at the same 4TB capacity right now - a live price fact, not a performance argument. See our Gen4-vs-Gen5 page for what published testing says that premium buys in practice.

This figure is computed fresh on every page load from live in-stock pricing, not a snapshot taken when this page was written - the actual dollar gap between generations at 4TB moves with the market, sometimes by a meaningful amount week to week, which is exactly why we compute it rather than state a remembered number. Treat it as today's answer to "what does Gen5 cost me at this size," not a durable industry fact.

Buying for 4TB specifically, versus a different size

If you arrived at this exact page from a search for 4TB specifically, it's worth double-checking that capacity is actually the right target before committing to it - our capacity guide lays out the same publisher-sourced install-size figures used above alongside the full live $/TB ladder across every size we track, so you can compare this capacity against its neighbors on one page rather than reloading this one repeatedly at different sizes. Nothing about the Gen4-vs-Gen5 question, the thermal considerations, or the DRAM-cache distinction changes by capacity - only how much of each you're buying does.

Reading the live tables above

Both tables are sorted cheapest-first by $/GB and refresh with the same pricing cycle as the rest of this site - a row that disappears has gone out of stock, not been removed from our catalogue. The Cache column shows DRAM or DRAM-less where our own data confirms it; a dash means the cache architecture is not confirmed for that specific listing rather than assumed either way. There is deliberately no speed column - see the doctrine note on the gaming SSD hub for why: every performance figure in this cluster is cited to a named publication, never asserted by us, and a bare manufacturer speed spec sitting in a sortable price table would invite exactly the apples-to-oranges comparison this cluster exists to avoid.

What this page does not do

It does not rank the drives above by speed, does not run a benchmark, and does not tell you which specific model to buy - it ranks by live price only, splits by generation so that comparison stays honest, and links to the cited testing this cluster relies on for the performance context a raw price table can't provide on its own. If you came here wanting a single "best 4TB gaming SSD" pick, the honest answer this page gives instead is: whichever row at the top of whichever generation's table fits your budget, since the cited testing elsewhere in this cluster found little reason to pay a premium for one drive over an equivalently-priced peer at the same capacity and generation.

Why this page can go thin, and what that means

This page only renders a full qualifying table when enough real, in-stock inventory exists at 4TB across both generations combined - the same exists-gate discipline this site applies to every capacity-specific page it publishes. If stock at this capacity thins out enough, this page is built to say so honestly rather than pad the table with an out-of-stock listing or a mismatched capacity dressed up as a fit. What you see above reflects real, currently-buyable inventory at the moment you loaded this page, not a static snapshot from whenever this page was first built.
