Micron 7400: PCIe 4.0 SSDs in 7 formats for the data center

The enterprise SSDs of the Micron 7300 series were already available in various form factors. Now Micron has introduced the successor with the 7400 series. These are faster thanks to PCIe 4.0 technology and are also available in the new E1.S form factor and with a universal U.3 connection.

Like the 7300 models, the Micron 7400s are offered with storage capacities from 400 GB to 7.68 TB. By switching from PCIe 3.0 to faster technology with PCIe 4.0, the performance (throughput as well as IOPS per watt) should more than double at the top. The essential components (controller, NAND and DRAM cache) come from our own company.

Seven formats for the data center

The possible uses in servers and data centers should be as broad as possible “from the edge to the cloud“Fail, which is why Micron offers the 7400 SSD in seven form factors. This includes both the usual 2.5 inch and M.2 formats as well as E1.S as one of the new Enterprise and Data Center SSD Form Factors (EDSFF). The 2.5-inch variant with a thickness of 15 mm or 7 mm is also available with a U.3 interface, which, as the successor to U.2, connects NVMe as well as SATA and SAS drives in the server via a universal backplane can.

In the case of the Micron 7400, the electrical interface is PCIe 4.0 x4 in connection with the NVMe protocol according to version 1.4. In addition, the fastest version (U.3) should achieve sequential transfer rates of up to 6,600 MB / s when reading and 5,400 MB / s when writing. As usual, Micron divides into “Pro” versions with 1 Drive Write Per Day and “Max” versions with a higher write guarantee of 3 DWPD. The Max version has less usable storage space, but a larger spare area, which increases durability and write performance. The largest 7400 Max (U.3) with 6.4 TB achieves a maximum of 363,000 IOPS with random writing, while the largest 7400 Pro (U.3) only achieves 190,000 IOPS with a larger storage space of 7.68 TB. With random reading, both top models are specified with one million IOPS.

    The performance of the E1.S versions as a plug-in module with heat sink corresponds to that of the U.3 models with up to 3.2 TB (Max) or 3.84 TB (Pro). The “naked” M.2 versions without a cooler are again significantly reduced in terms of performance. There is a maximum of 4,400 MB / s reading and 2,200 MB / s writing as well as lower IOPS.

    The SSD controller has four cores and is combined with Micron’s TLC-3D-NAND of the 96-layer generation. The internal NAND interface works at 1,200 MT / s. In contrast to Micron’s new OEM SSDs, the new 176-layer NAND with 1,600 MT / s is not yet in use.

    In addition to backward compatibility with PCIe Gen 3 systems, the 7400 series supports up to 128 namespaces as well as security standards such as TCG Opal 2.01 and IEEE1667. The M.2 version with a length of 80 mm is the only one with PCIe 4.0 that offers protection against power failure, according to the manufacturer. A figure shows the necessary backup capacitors.

    According to Micron, the 7400 SSD series will be available to business customers with immediate effect. Prices are not communicated publicly in this segment.
