Crucial® P3 1 TB NVMe M.2 SSD (Model CT1000P3SSD8)
Overview
The Crucial P3 1 TB is a modern NVMe PCIe Gen3 x4 M.2 2280 SSD- offering an excellent balance between high capacity- speedy performance- and affordability. Ideal for boot drives- applications- and storing games- it delivers significantly faster performance than SATA SSDs and HDDs.
Key Features
High-Speed NVMe Interface
-
PCIe Gen3 x4 NVMe 1.3 interface delivers up to 3-500 MB/s sequential read and 3-000 MB/s sequential write speeds.
-
Up to 650K IOPS read and 700K IOPS write for 4K random workloads.
Advanced Flash & Controller
-
Uses 176-layer Micron QLC NAND paired with a Phison PS5021‑E21T controller. There is no onboard DRAM; instead- it uses Host Memory Buffer (HMB) and a ~250 GB pseudo‑SLC cache to boost write performance.
Capacity & Endurance
-
Offers a full 1 TB (1000 GB) of usable storage.
-
Endurance rating of 220 TBW- suitable for several years of typical use.
-
MTTF (Mean Time To Failure) of over 1.5 million hours.
-
Covered by a 5-year limited warranty.
Performance & Use Case
-
Read/write speeds outperform most SATA SSDs and HDDs- enhancing boot-up- file transfer- and application load times.
-
Well-suited for gaming- productivity tasks- and as a primary boot drive in systems lacking NVMe Gen4 support.
Pros & Cons
Pros
-
High sequential speeds for a PCIe Gen3 SSD (3-500/3-000 MB/s).
-
Excellent price-to-performance ratio.
-
Spacious 1 TB storage with long warranty and reliable endurance.
Cons
-
QLC NAND and no DRAM can lead to slower sustained writes once cache fills.
-
PCIe Gen3 ceiling limits compared to Gen4 NVMe SSDs offering 5-000 MB/s+ speeds.
-
Best as primary or secondary storage—not for intensive write-heavy workloads.
Frequently Asked Questions
Q: Is it a worthy upgrade over SATA SSDs?
A: Absolutely — NVMe performance is up to six times faster than SATA SSDs- offering dramatically faster boot and load times.
Q: How does it fare under sustained write operations?
A: Initial writes use the fast SLC cache (~250 GB)- but performance slows to around ~100 MB/s afterwards.
Q: Will the endurance last?
A: With 220 TBW endurance and typical consumer usage- it should last multiple years. Covered by a 5‑year warranty.
Q: Does it support TRIM- SMART- and firmware updates?
A: Yes. Crucial’s SSD management tools support TRIM- SMART diagnostics- and firmware updates.
Q: Suitable for gaming or content work?
A: Yes—for gaming- media editing- multitasking- or as system storage—especially in systems without PCIe Gen4 support.
