Seize the 4TB WD Black SN7100 SSD at an all-time low Amazon price - the most energy-efficient storage solution perfect for your laptop, PlayStation 5, or PC
The WD Black SN7100 SSD stands out as a top-tier choice for gaming and general use, delivering impressive real-world PCIe Gen4 performance. With sequential read and write speeds of up to 7250MB/s and 6900MB/s respectively, this drive offers efficient and consistent speed without sharp drops under load.
Powered by SanDisk's proprietary Polaris 3 controller and 218-layer TLC (BiCS8) technology, the SN7100 operates without DRAM cache but utilises Host Memory Buffer (HMB) to maintain performance levels suitable for gaming and typical workloads. Although it may lag slightly behind premium DRAM-equipped drives in heavy sustained write scenarios like video editing, it more than compensates for this in its excellent gaming performance and power efficiency.
Comparatively, the WD Black SN850X, another high-end PCIe Gen4 SSD, performs competitively against the SN7100. In real-world gaming and PS5 use, the SN7100 often matches or even beats the SN850X, thanks to its efficient controller and firmware optimizations.
For those seeking even faster speeds, the WD Black SN8100, a PCIe Gen5 drive, offers sequential read speeds of up to 14,700MB/s. However, these drives come at a higher cost and higher power consumption. The SN7100, on the other hand, remains a strong, cost-effective choice that is more than sufficient for most gaming and creative tasks without the premium price of Gen5 SSDs.
In terms of endurance, the WD_Black SN7100 is rated at 2,400TBW, ensuring durability for long-term use. The drive is a single-sided SSD with a 2280 form factor and a capacity of 4TB, making it a versatile option for various devices.
Currently, the WD Black SN7100 is available at Amazon for US$229, a discount from its original price of US$269, offering even more savings for those looking to upgrade their storage.
