Yesterday we noticed Memblaze introducing a brand new collection of low-power server-class NVMe SSDs that concentrate on offering wonderful efficiency while sustaining decrease energy consumption ranges, aiming at enterprises bettering their storage vitality effectivity. The new PBlaze5 C520, D520, C526 and D526 SSDs are available both 2.5” U.2 or HHHL form-factors in two capability courses for every mannequin.
Unlike its larger brethren C900 collection fashions which we had reviewed final yr, the brand new 52X collection models restrict their efficiency traits by sticking to a PCIe 3.zero x4 interface, with all units lined at present peaking at a sequential learn velocity of three.3GB/s.
The 520 fashions include in both 1.92TB or 3.84TB variants, whereas the 526 fashions characteristic in 1.6TB or 3.2TB configurations. Random learn IOPS are available at a flat 520Ok for all of the fashions, while random write IOPS for the 520 collection vary from 68Ok on the 1.92TB unit to 70Ok on the three.84TB unit. The D526 and C526 each measure in at 135Ok random write IOPS.
As against the 900 collection SKUs which both use 32- or 64-layer enterprise 3D TLC NAND, the brand new extra vitality environment friendly fashions use newer 96L chips.
The cause why’d you wish to select these decrease energy fashions is after all for deployments which require larger vitality conservation or decrease warmth producing {hardware}. Compared to the 900 collection, idle energy consumption is decreased from 7W to right down to 4W, while working energy reduces from 25W to 9W, with an marketed 12W peak consumption.
