This article covers Crucial P310 M.2 2280 2TB PCI-Express 4.0 x4 NVMe 3D NAND 内蔵ソリッドステートドライブ (SSD) CT2000P310SSD8。.

Overview

The Crucial P310 CT2000P310SSD8 is a 2TB internal SSD built on Micron's 232-layer QLC NAND and the Phison E27T controller. It uses a PCIe 4.0 x4 interface with the M.2 2280 form factor, delivering sequential read speeds of up to 6,600 MB/s and writes up to 5,500 MB/s. Despite being DRAM-less, it leverages Host Memory Buffer (HMB) to maintain responsive real-world performance for everyday file transfers and game loading. This SSD is also compatible with the PlayStation 5's internal storage expansion, making it a strong candidate for console gamers who need more space. Launched in July 2024, the 2TB variant offers a TBW rating of 1,200 TB, providing long-term endurance for most users. Priced around ¥52,300 (approx. $350 USD), it targets the entry-to-mid-range market where cost efficiency matters.

Compatibility Guide

Form Factor: M.2 2280 — fits most desktop motherboards and laptops with an M.2 slot. Older platforms (e.g., Intel 100-series, early AMD AM4) may lack PCIe 4.0 support; the drive will fall back to PCIe 3.0 speeds (around 3,500 MB/s). Interface: PCIe 4.0 x4 NVMe — works in PCIe 3.0 slots with reduced bandwidth. Supported Devices: Desktop PCs, laptops with M.2 2280 slots, PlayStation 5 (requires separate heatsink), Xbox Series X|S (unofficial). For PS5, PCIe 4.0 is mandatory, so ensure your console firmware is up-to-date. Thermal Considerations: The DRAM-less design keeps heat generation moderate, but in confined spaces like a PS5 or thin laptop, adding a low-profile heatsink is recommended to maintain sustained performance.

Product Info

The Crucial P310 2TB (CT2000P310SSD8) is an entry-to-mid-tier NVMe SSD using QLC NAND (Micron 232L) with HMB for DRAM emulation. Its sequential performance is near the ceiling of PCIe 4.0, while random performance remains practical for typical usage. Power consumption is low — around 5W under load and under 0.5W at idle — benefiting laptop battery life. The drive comes with a 5-year warranty and is widely available through Crucial's official store and major retailers like . In the market, it competes directly with other QLC-based SSDs such as the WD Blue SN580 and Samsung 990 EVO. The P310 stands out for its high TBW rating (1,200 TB) among QLC drives, offering durability that approaches some entry-level TLC models.

Best Use Cases

Gaming: Ideal for storing AAA titles that benefit from fast level loading. The PCIe 4.0 speed reduces load times significantly compared to SATA SSDs. Not recommended for users who frequently rewrite large files (e.g., 4K video editors) — a TLC drive like the Crucial T500 would be better. PS5 Storage Expansion: Perfect for expanding the console's limited internal storage. The P310 meets PS5's PCIe 4.0 requirement, and 2TB can hold 20-30 modern games. Note: Sony recommends using a heatsink; the drive itself does not include one. Laptop Upgrades: Low power draw and modest heat make it suitable for laptops with M.2 2280 slots. Check clearance for double-sided NAND — the P310 is typically double-sided, so ultra-slim laptops may not fit. Budget-Conscious Large Storage: If you need 2TB of fast storage without spending premium prices, the P310 offers excellent value. However, if you plan to write hundreds of gigabytes daily, step up to a TLC model. ## Alternatives
Western Digital WD Blue SN580 2TB: Similar QLC/DRAM-less design with lower sequential reads (4,150 MB/s) but competitive random performance. Usually cheaper than the P310. Choose SN580 if cost is the top priority; P310 if you want maximum PCIe 4.0 bandwidth. Samsung 990 EVO 2TB: QLC with a hybrid PCIe 4.0/5.0 interface. Performance is comparable, but the price is higher. Samsung's Magician software is a plus. The P310 provides better value for pure PCIe 4.0 use. * Crucial T500 2TB (TLC): For users who prioritize write endurance. The T500 uses TLC NAND and has higher random write performance. Expect to pay 20-30% more. If your workload involves heavy writing, the T500 is the better choice.

Things to Consider

QLC Endurance: The 1,200 TBW rating is generous for typical home use (equivalent to ~3.3 years of 1TB/day writes), but heavy writers should look at TLC alternatives. DRAM-less Performance: HMB works well with modern chipsets, but if you plan to use this drive in an older system or an external enclosure without HMB support, performance may suffer significantly. No Included Heatsink: Especially important for PS5 and laptop installations. Budget for an aftermarket heatsink if needed. Price Fluctuation: At roughly ¥52,300 ($350), it's competitively priced, but sales can drop it to around ¥45,000. Timing your purchase can save money. * 2TB vs 1TB: The 1TB variant (CT1000P310SSD8) costs about two-thirds the price; if you don't need the extra capacity, consider saving. ## FAQ Q: Will this work in a PS5? A: Yes. The P310 is PCIe 4.0 compliant
