8TB is the maximum PS5 SSD capacity and enthusiast-tier territory. Very few PS5-suitable 8TB M.2 NVMe drives exist — the main licensed options are Samsung 990 PRO 8TB and WD Black SN850P 8TB. Both carry meaningful $/GB premiums versus 4TB. Justified only for buyers with the largest AAA libraries who want the entire collection installed simultaneously across multiple years without touching storage management. Not necessary for most players; 2TB or 4TB delivers better value.
The maximum PS5 supports. Fits 60-80 modern AAA titles simultaneously. Appropriate for digital collectors with extensive PSN libraries, streamers with content archives, and enthusiasts who want to configure storage once and never revisit the decision. The $/GB premium versus 4TB is meaningful; validate the use case justifies the cost.

After the PS5's ~6% file system overhead, a 8TB drive delivers approximately 7,520GB of usable capacity. What that translates to in real games depends on library composition — modern AAA installs vary from 50GB (smaller titles, well-optimized indies) to 200GB+ (Call of Duty, GTA 6) with an 80-100GB average for most current-gen releases.
Use the PS5 storage calculator to model your specific library composition.
For GTA 6 specifically, 8TB is overkill unless you also have a large library of other AAA titles installed. GTA 6 at ~250GB uses only 3% of an 8TB drive. Justify 8TB by the total library size rather than by GTA 6 itself. For the specific goal of installing GTA 6 comfortably, 2TB or 4TB is the right answer.
GTA 6 launches November 19, 2026. Buy your upgrade in the weeks ahead of launch to avoid the demand spike that historically hits PS5 SSD pricing at major AAA releases. See the full GTA 6 storage upgrade guide.
Every 8TB PS5 SSD needs a heatsink — Sony's requirement, not optional. Buy a 8TB drive with a factory-integrated heatsink (Samsung 990 PRO Heatsink, WD Black SN850P, Corsair MP600 Pro LPX) or pair a bare drive with a separate PS5-compatible heatsink from Sabrent or a similar accessory brand. Total drive-plus-heatsink height must be ≤11.25mm to fit the expansion compartment cover. See the heatsinks guide for current picks.
The cheapest 8TB PS5-compatible SSD on DatacenterDisk right now is the Acer 8TB Predator GM7 4TB : 2280 x4 2.0 at $702.99 ($0.088/GB). Prices update every 2 hours; check the live table above for the current winner.
Massively yes. 8TB is enthusiast-tier — GTA 6 uses only 3% of an 8TB drive. Justified by total library size rather than GTA 6 alone.
All 8TB PS5-compatible SSDs use PCIe Gen4 x4. Gen3 does not meet the 5,500 MB/s minimum read speed PS5 requires. Gen5 drives work in PS5 but run at Gen4 speeds — no performance benefit for the price premium.
Yes. Sony requires cooling for all M.2 expansion slot drives regardless of capacity. Either buy a 8TB SSD with a factory-integrated heatsink (Samsung 990 PRO Heatsink, WD Black SN850P, Corsair MP600 Pro LPX) or add a separate PS5-compatible heatsink from Sabrent or similar accessory brands. Total drive-plus-heatsink height must be ≤11.25mm.
On approximately 7,520GB of usable capacity after formatting overhead: about 150 indie/casual games at 50GB average, or about 94 standard AAA titles at 80GB average, or about 75 demanding AAA titles at 100GB average (Call of Duty, GTA 6). Real-world results depend on your specific library composition.
For GTA 6, the best 8TB PS5 SSD combines Gen4 NVMe, ≥5,500 MB/s sequential read, integrated heatsink (or add-on), and DRAM cache. Top picks include Samsung 990 PRO with Heatsink 8TB, WD Black SN850P 8TB (PS5 licensed), and Corsair MP600 Pro LPX 8TB. Live $/GB ranking above shows the current winner.
