The G Series HE’s energy-efficient design ensures seamless integration into modern PC environments. It delivers stable performance even during high-demand tasks such as gaming and video editing. With superior stability and reliability, it is perfect for long-term use. Whether you are seeking the next-gen high-speed storage experience or choosing your first Gen5x4 SSD, the G Series HE is the ideal choice.
Reliable Durability
Dynamic SLC Caching
This contributes to a longer life by reducing the workload on the NAND while speeding up the transfer of frequently accessed data.
Advanced wear-leveling
Advanced wear-leveling algorithms efficiently and evenly distribute data write/erase cycles to each area of the NAND flash memory: contribute not only to improving performance but to extending the life of TLC NAND.
LDPC
The controller is equipped with LDPC (Low-Density Parity Check) ECC algorithm, which detects and corrects reading errors with high accuracy, and protects from data corruption caused by the aging of flash memory cells.

- The maximum performances in the text represent the performance of NN5HE-2TB. Performance and power consumption may differ depending on the measurement conditions. Since the measured value also depends on factors other than the items described above, the indicated performance are not guaranteed. The measured value is based on the following conditions:
<Sequential transfer speed>
CPU: AMD Ryzen 7 7700X 8Core Processer
Motherboard: ASUS ROG STRIX X670E-E GAMING WiFi
OS: Windows 11 (10.0) Professional 64bit
Measurement software: CrystalDiskMark8, 1GB range, SEQ1MQ8T1

Motherboard : ASUS ROG STRIX X670E-E GAMING WiFi
OS : Windows 11 (10.0) Professional 64bit
Measurement software: IOMeter, 1GB range, 4K data size, QD=32T16 - TBW is calculated based on JEDEC 218/219 workload(client workload).
- MTBF is calculated based on simulation software (Relex7.3). High capacity drives are expected to have low MTBF and the minimum MTBF applies to all capacities.
