The largest factor with QLC-based SSD, particularly on this planet of hyperscalers, is staying power, the power of a garage tool to resist humongously huge quantities of writes. Measured in DWPD (drives written in step with day), it’s the baseline wherein all undertaking SSD are measured.
Solidigm introduced a brand new force, the D5-P5430, which is to be had in capacities starting from 3.84TB to 30.72TB and objectives to give a boost to the staying power of QLC force, presenting it as an immediate TLC SSD alternative.
As such, it enhances, moderately than replaces, the D5-P5316 which is a 144-layer NAND founded SSD which is the most affordable 30.72TB SSD lately available on the market with costs soaring round $2500, or more or less $80 in step with TB (when compared, consumer-grade QLC SSD drives value round $50 in step with TB).
The D5-P5430 makes use of more moderen 192-layer NAND and delivers a DWPD on random workloads of 0.58 the use of a 4KB indirection unit (Solidigm quotes 32 Petabytes written), which is upper than the D5-P5316 which reached 0.41 the use of a 16KB indirection unit. By contrast, the simply introduced 6500 ION (which pitted itself in opposition to the 5316) has a DWPD of 0.3 with a 4KB IU.
Solidigm is making plans a 61.44TB SKU for its P5316 circle of relatives, perhaps for later this . This will coincide with the release of the 30.72TB SKU for the P5430 as simplest smaller variations (as much as 15.36TB) are to be had at the moment (Micron’s 6500 ION simplest is available in one capability: 30.72TB).
A evaluate of the beast by way of Storagereview (opens in new tab) displays that it will have to be aggressive performance-wise with its Micron rival. Any other noteworthy function is its availability as a 7.5mm E3.S (for as much as 25W energy dissipation) which permits extra drives to be squeezed nearer in combination. The 6500 ION makes use of the thicker U3 shape issue and provides a stocky passive heatsink to it.
That implies that a 1U gadget may just pack simply over 600TB and a staggering 1.2PB in a 2U configuration (the use of 40 drives). Provantage sells the D5-P5430 for a trifling $1,217 which is shockingly inexpensive for a force of this measurement (not up to $80 in step with TB) because of this that the 30.72TB model will have to be a minimum of as inexpensive because the P5316.
Extra 30TB SSDs at the means?
Till just lately, Samsung’s PM1643 used to be the one huge capability (30.72TB) force to be had. Since then, Nimbus information launched two 32TB SSDs (in addition to a 64TB, 50TB and 100TB fashion), Samsung added the PM1653 and the PM1733, Kioxia presented the PM6 and the CM6 whilst Micron introduced the 9400 Professional and the 6500 ION and Solidigm dropped the D5-P5316. There are naturally different area of interest gamers (Natural Garage, Liqid Component) with both proprietary answers or merchandise that focus on a small phase of the garage marketplace.
