The last Samsung drive we looked at, the 990 EVO Plus, was a kind of halfway house between Gen 4 and Gen 5 as it used a Gen 4 x4 / Gen 5 x2 interface. Now, however, we have Samsung's first full-blown Gen 5 x4 consumer drive to hand, the SSD 9100 Pro. Let's put it through its paces and find out just how fast this drive is.
At launch, the SSD 9100 Pro product line consists of three capacities: 1TB, 2TB and 4TB. A flagship 8TB model is due to come in the 3rd quarter of 2025. Two versions of the drive are available, one plain and one with a heatsink.
The 9100 Pro uses Samsung's in-house PCIe 5.0 Presto controller combined with the company's eighth-generation V-NAND technology. The onboard cache is provided by an LPDDR4X IC (up to 4,266 Mbps) which is sized at 1GB per 1TB of storage capacity.
The Sequential read performance of the range is quoted as up to 14,700 MB/s for the 1TB and 2TB drives and up to 14,800MB/s for the 4TB model. The 1TB drive gets an up to 13,300MB/s Sequential write rating with the 2TB and 4TB models a little faster at up to 13,400MB/s.
Random 4K performance is quoted as up to 1,850,000 IOPS for the 1TB and 2TB drives with the 4TB model at up to 2,200,000 IOPS. All three drives are rated at up to 2,600,000 IOPS for random writes. These random figures are from testing at QD256 using 32 threads.
The 2TB drive has power consumption figures of 8.1W and 7.9W for average active reads and writes respectively.
The TBW endurance for the 2TB 9100 Pro is quoted as 1,200TB and the drive is backed by a 5-year warranty.
