With the growing demand for memory driven by the rise of artificial intelligence, storage prices have continued to increase. However, there are still affordable options available, such as the 1 To SanDisk Optimus GX 7100 SSD. This model, previously known as the WD Black SN7100, is currently on sale during Amazon's Prime Flash Days for around 200 euros. The SSD offers a 1 To capacity, read speeds up to 7,250 Mo/s, and an endurance of 600 TBW. Originally priced at 237.99 euros, it is now available for 202.29 euros for Prime members. The 500 Go version is also discounted, priced at 105.39 euros instead of 123.99 euros. The SanDisk Optimus GX 7100 uses a PCIe 4.0 x4 interface and the NVMe 2.0 protocol, which allows it to be installed in most laptops and desktop PCs due to its M.2 2280 format. The manufacturer claims read and write speeds of up to 7,250 Mo/s and 6,900 Mo/s respectively, placing it among the top-performing PCIe 4.0 SSDs. These speeds help reduce loading times for both applications and resource-intensive games. In random read and write operations, the model can reach 1 million and 1.4 million IOPS, thanks to its integrated nCache technology. However, the SSD does not have a dedicated DRAM cache and instead uses the PC's RAM via the Host Memory Buffer (HMB). While this is generally not an issue for everyday use, an SSD with a dedicated DRAM cache may perform better during very large, prolonged writes. The SSD is also compatible with the PlayStation 5, as it meets Sony's main requirements, including a PCIe 4.0 x4 interface and read speeds above 5,500 Mo/s. However, it will need a thermal dissipator, and performance may be lower than expected due to the lack of HMB support in the PS5. In terms of endurance, the SSD can handle up to 600 To of data being written, and it comes with a 5-year warranty. SanDisk also provides its Dashboard software, available only on Windows, which allows users to monitor the drive's health, update the firmware, and activate a dedicated Game Mode to enhance performance during gaming sessions.
