If the comparison leaves someone sticking with Gen4, this is a solid example of what that tier still delivers: 7400 MB/s read speed over a PCIe 4x4 interface, with TRIM support for sustained performance. It fits desktop, laptop, and PS5 setups where Gen4 remains plenty fast without chasing Gen5 numbers.
Pros
- 7400 MB/s read speed near the top of PCIe 4.0 drives
- Works with PS5, where Gen5 isn't usable anyway
- SLC and HMB caching keep speeds steady under heavy load
- Biwin software simplifies cloning and drive diagnostics
Cons
- 1TB capacity may feel tight for large modern game libraries
- Older systems may need a BIOS update to unlock full speed
If you're weighing Gen4 against Gen5, the Predator GM7 is the strongest argument for staying on Gen4 a while longer. At 7400 MB/s read and 6500 MB/s write, it sits near the ceiling of what the PCIe 4.0 interface can deliver, which means you get Gen5-adjacent snappiness without needing a brand new motherboard. That matters for this comparison because the real question most upgraders face isn't raw bandwidth, it's whether their current platform can even use Gen5 speeds. For PS5 owners, Gen5 isn't an option at all, so this drive's 1TB capacity and sustained performance via HMB and SLC caching make it the practical answer. The thermal design keeps speeds consistent during long gaming sessions or big library transfers, and the Biwin software adds cloning and diagnostics for an easy swap. For anyone deciding between a Gen4 upgrade now versus waiting on Gen5 hardware, this drive makes the case that Gen4 still has plenty of headroom left for mainstream gaming and content work.
Buy this if you're on a PCIe 4.0 system or a PS5 and want a meaningful upgrade without rebuilding your platform around Gen5. It suits gamers and creators who need strong sustained speeds and 1TB of space. Skip it if you already have a Gen5-capable motherboard, since you'd be leaving performance on the table, or if you need more than 1TB for a sprawling game and media library.
For console and PC gamers specifically weighing this upgrade, this 1TB drive with heatsink hits 7,100MB/s on PCIe Gen4, enough to fully saturate a PS5's storage interface. It's a useful reference point for readers deciding if Gen5 speeds would actually matter for their gaming setup.
Pros
- Up to 7,100/6,000 MB/s on PCIe Gen4
- Integrated heatsink keeps temps controlled

How to Choose Between Gen4 and Gen5 SSDs
Confirm Your Motherboard’s M.2 Slot First
A PCIe Gen5 SSD works in a Gen4 M.2 slot, but it runs at Gen4 speeds there. Before buying, check your motherboard manual for an M.2 slot labeled PCIe 5.0 x4, then confirm that your CPU platform supplies Gen5 lanes to that slot.
The Crucial P510 PCIe Gen5 NVMe 1TB SSD supports Gen4 systems, making it a flexible choice if you plan to upgrade later. For a new performance-focused build, it is also smart to coordinate the drive with one of the graphics card options for modern PC builds, since lane allocation and motherboard layout can matter.
Look Beyond Sequential Speed Claims
Gen4 drives already offer very high throughput. The Samsung SSD 990 PRO 4TB, PCIe 4.0 M.2 2280 reaches up to 7,450 MB/s reads, while the Acer Predator GM7 1TB SSD reaches up to 7,400 MB/s. Those speeds are ample for responsive operating systems, game libraries, and most editing projects.
Gen5 opens more bandwidth for sustained large-file work. The Crucial T705 PCIe Gen5 NVMe 4TB SSD reaches up to 14,100 MB/s reads, and the WD_Black SN8100 4TB NVMe SSD – PCIe 5.0×4 reaches up to 14,900 MB/s reads. That gap is meaningful for huge media transfers, AI assets, and intensive project folders, although day-to-day app launches may feel closer than the figures imply.
Random performance, cache behavior, and the source drive all affect a transfer. If you often move files between drives, an M.2 to USB adapter for fast portable access can also be useful, but its enclosure and USB connection set the speed ceiling.
Plan for Heat Management and Physical Clearance
Gen5’s extra performance creates more thermal demand during long writes, rendering, or extended gaming sessions. A motherboard M.2 heatsink or a compatible aftermarket solution helps a Gen5 drive maintain steadier behavior instead of reducing speed to control temperature.
The Crucial T705 PCIe Gen5 NVMe 4TB SSD is designed for use with a compatible heatsink, while the Crucial P310 2280 1TB PCIe Gen4 NVMe Gaming PS5 includes a heatsink suited to consoles and many desktop builds. Check laptop space carefully, and review PC cables and adapters if your upgrade also involves an external enclosure or migration setup.
Choose Capacity for Your Actual Library and Workflow
Capacity often has a larger daily impact than moving from Gen4 to Gen5. A 1TB drive such as the Acer Predator GM7 1TB SSD or the Crucial P510 PCIe Gen5 NVMe 1TB SSD suits a focused OS, applications, and several large games. Heavy creators and users with extensive libraries will appreciate the headroom of 4TB options.
The Samsung SSD 990 PRO 4TB, PCIe 4.0 M.2 2280, WD_Black SN8100 4TB NVMe SSD – PCIe 5.0×4, and Crucial T705 PCIe Gen5 NVMe 4TB SSD are better aligned with large project collections. For lighter upgrades, the Western Digital 500GB WD Green SN3000 NVMe and Western Digital 512GB Gaming Gen4 M.2 2280 PCIe can refresh an older machine without requiring a high-capacity setup.
Also consider how you will protect important files before replacing a drive. Migration software can simplify the move, but a separate backup remains essential; our broader electronics upgrade resources can help you plan the surrounding hardware as well.
Final Thoughts
For most existing PCs and PS5 owners, a capable Gen4 drive remains the sensible route to fast loading and responsive everyday use. The Crucial P310 2280 1TB PCIe Gen4 NVMe Gaming PS5 suits that balanced role, while the Crucial T705 PCIe Gen5 NVMe 4TB SSD is the stronger fit for a well-cooled Gen5 workstation that handles demanding files regularly.
