FMS: Fast server SSDs with plenty of memory
Solidigm launches new server SSDs. The D7-PS1010 is said to be particularly fast, the D7-PS1030 particularly durable. Micron also has new models in its range.

The new server SSDs from Solidigm are said to achieve more than 3 million IOPS; the manufacturer speaks of the "fastest SSD in the world". These are available in two versions: The D7-PS1010 may be written to daily at its capacity (one Drive Write Per Day, 1 DWPD), while the D7-PS1030 allows three times this (3 DWPD) under warranty. The capacities start at 1.92 (D7-PS1010) and 1.6 TByte (D7-PS1030), the maximum capacities are 15.36 and 12.8 TByte respectively. Both variants come as a 7.5 millimeter thick E3.S plug-in unit and in a 15 millimeter high 2.5 inch housing with U.2 connection.
Solidigm states up to 3.1 million IOPS for reading, but does not specify any values for different capacity levels. The 1010 models achieve up to 400,000 IOPS when writing, while the D7-PS1030 achieves a maximum of double that with 800,000 IOPS. When reading large files, the Solidigm SSDs achieve 14.5 GByte/s, while Solidigm states a maximum of 9.3 GByte/s for writing.
The SSDs transfer their data via PCI Express 5.0; Solidigm developed the controller itself. The memory chips come from the parent company SK Hynix: 3D TLC flash with charge trap technology and 176 layers. The power consumption in idle mode is 5 watts; in operation, the SSDs should consume a maximum of 23 watts. When filled with random data, the endurance is up to 28 (D7-PS1010) or 70 (D7-PS1030) petabytes.
Partly even faster: Micron 9550
Last week, Micron also presented a server SSD that is said to be even faster than Solidigm's D7 models in some benchmarks. Like its predecessors, the 9550 is available in two versions, Pro and Max, the former has more storage space, the latter can handle more write cycles. The 9550 Pro may be completely overwritten on average a maximum of once per day under warranty (1 DWPD); this results in an endurance of up to 56 PBW (PByte written) over five years. The capacities are between 3.84 and 30.72 TByte. The models with 7.68 and 15.36 TByte are specified with up to 3.3 million IOPS when reading, the other two somewhat slower. The medium-sized models are also faster at 400,000 IOPS when writing; the 3.84 TByte model is reportedly at 280,000 IOPS, the 30 TByte at 380,000.

The Max version uses a larger part of its memory as a reserve for defective cells, so the storage space reaches a maximum of 25.6 TByte. The 9550 Max allows 3 DWPD with a maximum endurance of 140 PBW and is significantly faster when writing to random addresses: The 6.4 and 12.8 TByte models have 900,000 IOPS in the data sheet, while the other two are again behind with 600,000 and 750,000 IOPS. All Pro and Max versions are available with a U.2 connection in a 15 millimeter high housing and in the 7.5 millimeter thick E3.S format, the three smaller Pro versions are also available with an E1.S slot. When reading large files, all models should achieve 14 GByte/s, while the values for writing are reportedly between 6 and 10 GByte/s.
