A close comparison in Samsung’s lineup, the T9 Portable SSD costs $1,145 for the 4TB model and offers read and write speeds of up to 2,000 MB/s. It uses USB 3.2 Gen 2×2, not USB4, but also incorporates resilient features; such as drop resistance up to 9.8 feet.
Seagate’s LaCie Rugged SSD4 with USB4 costs $1,280 for 4TB with read and write speeds of up to 4,000 Mbps, much closer to Samsung’s P series. The Lacie is also IP54 rated and can withstand 9.8 feet of shock and up to a ton of pressure. LaCie scores highly on review sites like PCMag, and its drives are designed to be more durable, like Samsung’s P7, ideal for those on the go or on adventures. Think photographers who need extra storage, videographers in the field, remote professionals, that sort of thing.
There’s also the SanDisk Extreme PRO USB4 in 4TB for full price $1,250, with read speeds up to 3,800 Mbps and write speeds up to 3,700 Mbps. Corsair’s 4TB USB4 EX400U SSD costs $1,555 for read speeds of 4,000 Mbps and write speeds of 3,600 Mbps, directly comparable to Samsung’s P9. However, Corsair’s EX400U Survivor series, a rugged offshoot, is less expensive, around $590 for a 4TB model with speeds of 4,000 Mbps read, 3,600 Mbps write, and an IP55 rating. However, you will find many out of stock at retailers. If Samsung can provide better availability for the P series, it will go a long way towards its success. Other brands with robust USB4 and fast SSDs include Oyen, Glyph Technologies, WD Black, PNY, Lexar, and Kingston.
