If your workstation build has no budget limits, there's now a way to get 16 TB of NVMe PCIe 4.0 SSD storage on a single M.2 2280 SSD. However, this small storage drive will set you back nearly $16,000, with Amazon listing a brand new Exascend PE4 16 TB M.2 SSD at $15,935. What makes this drive so expensive is the fact that you are getting 16 TB of NVMe SSD storage in a super-dense configuration that fits into a single M.2 slot on a motherboard, requiring no additional drives to achieve this capacity. The Exascend PE4 drive uses a PCIe 4.0 interface and can reach sequential read speeds of up to 3,270 MB/s, while write speeds can reach up to 2,980 MB/s, just shy of 3 GB/s. The drive uses TLC 3D NAND Flash storage modules from an unknown manufacturer.

The drive is designed to withstand a TBW of 16,640 TB written to it and about two million hours of MTBF, meaning its usable life is guaranteed to last through any known task, running 24/7 in systems where reliability is the number one factor. Interestingly, Exascend only offers a five-year warranty but claims its hardware will significantly outlast that. Rigorous testing and massive capacity justify the high price point, so some users might find the need for such a drive. Additionally, idle power consumption remains under 1.3 W, while this SSD can reach up to 7.2 W of active power when under full load, meaning that efficiency for such a drive is rather good.
