4TB is the future-proof PS5 SSD capacity. It fits GTA 6, a comprehensive current AAA library, GTA Online expansion updates through 2027-2028, and pretty much anything else you want to install without ever needing to delete. The $/GB premium over 2TB is modest at 2026 pricing — typically 10-20% higher $/GB rather than 40-60% higher. Appropriate for buyers who install everything and never delete, digital collectors with large PSN libraries, and anyone who wants to make one storage decision and forget about it.
GTA 6 plus a comprehensive AAA library (30+ current-gen titles) plus indies plus expected GTA Online expansion content through 2028 all fit on 4TB with headroom to spare. Appropriate for buyers who install everything and never delete, digital collectors, and streamers/content creators who want instant access to a large game library for content production.
After the PS5's ~6% file system overhead, a 4TB drive delivers approximately 3,760GB 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 is estimated at 150-200GB, unconfirmed) with an 80-100GB average for most current-gen releases.
Use the PS5 storage calculator to model your specific library composition. If you have narrowed it to Samsung, the 990 Pro family page prices every capacity and both heatsink variants side by side.
For GTA 6 specifically, 4TB is the future-proof choice. GTA 6, GTA Online updates through 2028, a comprehensive AAA library, and indies all fit with meaningful headroom. Appropriate for buyers who want to install GTA 6 alongside 30+ other games without ever deleting anything. The $/GB premium versus 2TB is modest for the peace of mind.
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 4TB PS5 SSD needs a heatsink — Sony's requirement, not optional. Buy a 4TB 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 4TB PS5-compatible SSD on DatacenterDisk right now is the Fikwot FX660 4TB M.2 SSD at $436.99 ($0.109/GB). Prices update every 2 hours; check the live table above for the current winner.
Yes, and comfortably. 4TB fits GTA 6, a comprehensive AAA library, GTA Online expansion updates through 2028, and indies with meaningful headroom. Future-proof choice.
All 4TB 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 4TB 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 3,760GB of usable capacity after formatting overhead: about 75 indie/casual games at 50GB average, or about 47 standard AAA titles at 80GB average, or about 37 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 4TB 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 4TB, WD Black SN850P 4TB (PS5 licensed), and Corsair MP600 Pro LPX 4TB. Live $/GB ranking above shows the current winner.
