Adata launches its first mainstream PCIe 4.0 SSD

Adata is rolling out a PCIe 4.0 SSD family for “mainstream” users, which is usually focused on slower and cheaper than an enthusiast-branded product. As such, its new Gammix S50 Lite is rated to deliver up to 3,900MB/s of sequential read performance and up to 3,200MB/s of sequential writes. In a vacuum, those are impressively fast speeds. But considering PCIe 4.0 storage, the Gammix S50 Lite is the slowest line. The advent of PCIe 4.0 SSDs has introduced blistering fast read and write speeds that initially checked in at around 5,000MB/s, followed by a spattering of newer models that crank the dial to 7,000MB/s (compared to SATA models that top out at around 580MB/s). SSD and RAM pricing has actually come down in recent weeks, but there is still room to put in a more affordable PCIe 4.0 series, which Adata is trying to do. As for durability, Adata is claiming 1,480 TBW (terabytes written) and backs these drives with a 5-year warranty. There will be two capacities offered, 2TB for $300 (around Rs. 22,000) and 1TB for $150 (around Rs. 11,000).
