8TB Gaming SSD: Gen4 & Gen5, Live Prices

Updated 2026-09-16

What 8TB 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 8TB drive holds all five of those example titles installed simultaneously, with roughly 7.4TB 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 8TB suits

8TB is the tier where capacity stops being the constraint for nearly any single-drive gaming library, per the arithmetic above - the remaining headroom after installing every example title cited on our capacity guide is itself larger than most buyers' entire libraries. This tier suits buyers consolidating multiple smaller drives into one, or maintaining an unusually large rotating library without ever uninstalling.

A realistic scenario at 8TB

An 8TB drive used purely for games, per the publisher figures cited above, could hold dozens of large current titles simultaneously - the practical constraint at this tier shifts from "will it fit" to "is this the right amount of money to spend on capacity headroom you may not use." That's a genuinely different question from the one smaller tiers answer, and it's why this page frames 8TB as suited to a specific stated need rather than a default recommendation.

How 8TB compares to the capacity next door

8TB carries the smallest population of qualifying listings we track in this cluster, and per-gigabyte pricing at this tier reflects that - it is priced for buyers who have a specific, large-library reason to want it, not as the default recommendation this page would give a typical buyer. See the live $/TB ladder on our capacity guide for exactly how much premium today's market is charging for the extra headroom over 4TB.

The same-money note

The cheapest Gen5 drive at 8TB costs $590.35 more than the cheapest Gen4 drive at the same 8TB 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 8TB 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 8TB specifically, versus a different size

If you arrived at this exact page from a search for 8TB 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 8TB 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 8TB 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.
