- Sequential read speeds that reach 14.900 MB/s thanks to the PCIe 5.0 x4 interface.
- 218-layer TLC flash memory with BiCS FLASH technology and LPDDR4X DRAM cache.
- Robust durability of 1.200 TBW and an extended 5-year warranty.
- Silicon Motion SM2508 controller manufactured using TSMC's 6nm process.
If you're looking to give your computer a speed boost, the 2TB Kioxia Exceria Pro G2 sets the bar very high. This is a high-performance drive, positioning itself as the top-of-the-line NVMe drive in the brand's lineup, ideal for those who don't want to wait a single second for their programs to load.
This device isn't just about raw capacity, but pure efficiency. By leveraging the technological leap to the PCIe 5.0 interface, it makes data transfer incredibly smooth, achieving a much more optimized energy-to-read-rate ratio than previous generations—a particularly welcome feature in laptops.
Performance and Technical Specifications
Getting down to brass tacks with the numbers, this SSD is a beast. Sequential read speeds reach 14.900 MB/s , a figure that leaves the competition in the dust and remains consistent in both the 2 TB and 4 TB models. As for write speeds, the manufacturer quotes around 13.400 MB/s , ensuring smooth workflow even with large files.
Looking at operations per second (IOPS), the 2TB model sits in a well-balanced middle ground, reaching 2.250.000 IOPS for reading and 1.950.000 IOPS for writing. To achieve such a feat, Kioxia has implemented a Silicon Motion SM2508 controller , manufactured with TSMC's 6nm technology, which manages all data traffic with surgical precision.
We mustn't forget that this drive comes equipped with 2 GB of LPDDR4X-4266 DRAM cache , which prevents bottlenecks. Furthermore, it uses 218-layer TLC flash memory based on BiCS FLASH technology and employs a pseudo-SLC cache system for significantly faster write bursts.
Construction, Durability and Warranty
In terms of physical components, we find the classic M.2 2280 format. A key detail to note is that the top label is designed with high thermal conductivity , helping to prevent heat buildup and ensuring the drive doesn't suffer performance drops due to high temperatures during intense gaming or video editing sessions.
Speaking of peace of mind, Kioxia hasn't skimped on protection. The drive comes with a 5-year extended warranty and a rated durability of 1.200 TBW (Terabytes Written) for the 2 TB version. While the MTTF value is a statistical figure of 1,5 million hours and not an exact lifespan guarantee, it indicates that we're dealing with an extremely reliable component.
Clarifications on Capacity and Operation
It's important to note that, as with almost all storage, there's a difference between what the box says and what you see in Windows. Kioxia uses decimal notation (where 1 TB is 1 trillion bytes), but operating systems use powers of 2 , so the actual available space will always appear somewhat less. Furthermore, the final amount of space will depend on the format and pre-installed software.
For more technical users, it's worth noting that this SSD is not compatible with PCIe Vendor Defined Messages (VDM). It's also crucial to remember that speeds can vary depending on the motherboard or host device. As a precaution, frequent backups are always recommended , since no manufacturer can guarantee the complete integrity of stored data against unforeseen events.
This drive represents the perfect balance between extreme speed and durability, offering a PCIe 5.0 x4 interface capable of moving massive volumes of data with amazing energy efficiency and a warranty backing that gives the end user a lot of peace of mind.
