Samsung SSD 9100 Pro: 8 TByte with PCIe 5.0 on 80 millimeters length

Samsung is launching its fastest SSD 9100 Pro in a version with 8 TByte storage capacity. The manufacturer thus combines the highest capacity level in an M.2 SSD for end customers with performance close to the top. With PCI Express 5.0 and a read speed close to 15 GByte/s and 13.8 GByte/s when writing, the SSD 9100 Pro is one of the fastest models.

The new 8 TByte version should also achieve 14.8 and 13.4 GByte/s for sequential access. Samsung promises 2.2 or 2.6 million IOPS for accesses to random addresses. The power consumption increases to a maximum of 10.5 watts, which is probably also due to the doubled DRAM cache – this is now 8 GB.

Components from our own production

As with the lower capacity versions, Samsung uses its own controller, codenamed Presto, and TLC flash components from its production, and the other characteristics are also in line with expectations: The SSD may be written to 4800 TByte within the five-year warranty period, and Samsung states the probability of failure as 0.58 percent per year. Like the smaller versions, the 8-TByte version is available with and without a heat sink – but it is better to avoid operation without a heat sink. However, the heat sinks of modern motherboards should be sufficient for the vast majority of applications.

According to Samsung, the SSDs will be available from September 2nd, priced at a hefty 965 and 984 euros for the versions with and without heat sinks respectively. As usual, prices are likely to fall: The 1, 2 and 4 TByte versions are currently just under 20 percent below the prices announced at the time; this means that a later street price of around 800 euros is possible for the 8 TByte versions. Other SSDs with 8 TByte are available from around 600 euros, but only with PCIe 4.0. You can find a test of such high-capacity M.2 SSDs at heise+ and in c't 13/2025.
