Samsung's fastest SSD is back to Prime Day pricing — only $30 difference between the much faster Gen 5 9100 Pro and Gen 4 990

(Image credit: Future) SSD prices in general remain considerably higher than a year ago. Still, this discount on Samsung's 9100 Pro 2TB SSD is a welcome sight, as Samsung's fastest PCIe Gen 5.0 drive returns to the lower pricing that we witnessed during the most recent Amazon Prime Day sales event at the end of last month. You can currently grab the 2TB Samsung 9100 Pro for $399.99 at Amazon, a discount of 41% compared to its list price. That's only $10 more than Samsung's excellent 2TB 990 Pro SSD at $389.99, and $30 more than Samsung's recently released 2TB 990 at $369.99, which are both previous-generation PCIe 4.0 SSDs with half of the available bandwidth speeds. ● Check out this Samsung 9100 Pro 2TB SSD deal at Amazon● Check out this Samsung 990 Pro 2TB SSD deal at Amazon● Check out this Samsung 990 2TB SSD deal at Amazon Samsung's 9100 Pro SSD boasts sequential read speeds of up to 14,700MB/s and write speeds of 13,400MB/s thanks to the available PCIe 5.0 bandwidth, making it one of the fastest drives on the market, perfect for heavy professional application workloads, and of course top-end gaming PCs.By contrast, the 990 Pro offers about half the read and write speeds of this drive at around 7,450/6,900MB/s, with the recently released Samsung 990 offering up to 7,250/6,450 MB/s, but switching from TLC to QLC NAND. These drives pretty much max out the PCIe Gen 4 bandwidth, with the new Samsung 990 being marketed as a budget-oriented SSD, but in reality and most importantly, in terms of pricing, the difference between the Samsung 990 and the much faster 9100 Pro is just $30. We've reviewed Samsung's 9100 Pro and found this impressive Gen 5 drive to be one of the fastest SSDs available to buy. During benchmark testing, the Samsung drive placed near the very top of the charts. In our PCMark 10 Storage tests. the 9100 scored higher than any other drive we've tested.

Or save a further $20 and opt for Samsung's latest SSD, the 2TB 990. This PCIe Gen 4 drive opts for QLC NAND, but still has fast access speeds. The drive can reach 7,250/6,450MB/s for sequential reads and writes and up to 850K/1,200K random read and write IOPS. RAM and SSDs are some of the toughest PC components to get your hands on at the moment at prices that won't give your bank account an aneurysm, so we take any discounts we can. Especially if it helps us build or upgrade our beloved PCs for slightly less. There's currently no end in sight for memory and NAND prices to return to more normalized values until manufacturers can ramp up production, and AI hyperscalers stop sweeping up all the demand. So definitely give these Samsung SSD deals a look if you're on the hunt for an SSD upgrade. Stewart Bendle is a deals and coupon writer at Tom's Hardware.
