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

Institutional SSDs for the Micron 7300 series are already available in a variety of formats. Now the successor to the Micron 7400 series has been unveiled. These are available soon thanks to PCIe 4.0 technology and with the new E1.S form factor and global U.3 connection.

Like the 7300 models, the Micron 7400 has a storage capacity of 400 GB to 7.68 dB. By switching from PCIe 3.0 to faster technology with PCIe 4.0, performance (performance and IOPS per watt) should be more than twice as high. The essential components (controller, NAND and DRAM cache) come from our own company.

Seven formats for a data center

Potential applications on servers and data centers should be as broad as possible. “From edge to cloud“Failure, that’s why Micron offers the 7400 SSD in seven formatting factors. Available with U.3 interface, it can inherit U.2, connect NVMe and SATA and SAS drives via global playback.

In the case of the Micron 7400, the power interface is PCIe 4.0 x4 with the NVMe protocol as per version 1.4. Additionally, the fastest version (U.3) should achieve continuous transfer rates of up to 6,600 MB / s when reading and up to 5,400 MB / s when writing. As usual, Micron divides it into “Pro” versions with 1 drive write per day and “Max” versions with a higher write guarantee of 3 DWPT. The Max version has less usable storage space, but a larger spare area, which increases durability and writing efficiency. The largest 7400 Max (U.3) reaches a maximum of 363,000 IOPS with 6.4 TB of random text, while the largest 7400 Pro (U.3) alone reaches 190,000 IOPS with 7.68 TB of large storage space. With random reading, the two best models are marked with one million IOPS.

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

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

In addition to lagging compatibility with PCIe Gen 3 systems, the 7400 Series supports 128 namespaces and security standards such as TCG Opal 2.01 and IEEE1667. The 80mm long M.2 version is only available with PCIe 4.0, which, according to the manufacturer, provides protection against power failure. An image shows the required backup capacitors.

According to Micron, the 7400 SSD series will come into effect immediately for business customers. Prices in this category are not publicly reported.
