We’ll forgive you if you haven’t heard of Exascend. Unlike the big mainstream brands, Exascend has largely focused on the enterprise market — making it a lesser-known brand for everyday consumers. That focus on enterprise needs is exactly why the Exascend PE4 stands out as an impressive SSD, even if it's a niche SSD. The PE4 comes in various form factors, including M.2 2230, 2242, 2280, E1.S, and U.2. However, 16TB is available in the M.2 2280 form factor, and the U.2 form factor maxes out at 30TB. The Exascend PE4 16TB is a high-capacity PCIe 4.0 SSD that delivers sequential read and write speeds of up to 3,270 MB/s and 2,980 MB/s, respectively. The random performance stands at 404,000 IOPS for reads and 52,000 IOPS for writes. These figures are essentially at the PCIe 3.0 level of performance. Remember that the PE4 isn't about being fast but density and endurance. In fact, it flaunts a mind-blowing endurance rating of 16,640TBW. Also, the operational temperature for the PE4 16TB is up to 70 degrees Celsius, so the drive requires a robust heatsink to function properly. The technology to manufacture 16TB SSDs for the consumer market has been available for some time. The main obstacles have always been high production costs and, more recently, ongoing storage component shortages. Until manufacturing returns to normal and the supply chain improves, it’s unlikely we’ll see 16TB M.2 SSDs in the consumer segment in the near future. For now, these massive drives, such as the Exascend PE 16TB, remain exclusive to the enterprise crowd.
The PE4 serves as a clear example that even enterprise-grade products are not immune to the AI tax. The PE4 16TB used to sell for $4,299.99 back in November 2025, but the price tag has nearly quadrupled in just four months. Even at these inflated SSD prices caused by the storage shortage, you can pick up two Samsung 9100 Pro 8TB for $3,190 , effectively matching the PE4 16TB's capacity at a fraction of the cost. The Samsung 9100 Pro is a PCIe 5.0 too, so the performance is night and day compared to the PE4. One of the most compelling features of the PE4 is that it delivers 16TB in a single drive, eliminating the need to combine multiple smaller drives to reach the same storage total. For storage enthusiasts and professionals alike, the prospect of installing a PE4 16TB in every available M.2 slot is exciting. On high-end consumer motherboards, which often feature up to five M.2 ports, the possibility of packing in 80TB of solid-state storage is beyond anyone's imagination. The PE4 16TB isn't something that will sell like pancakes. Although, at $15,935 a pop, Amazon claims it only has nine left in stock — so either the supply was thin to begin with, or there are a lot of professionals with deep pockets picking these up.
