It’s humorous how issues come full circle. In some ways, The SSD Assessment is the place it’s in the present day on account of a detailed good friend named Kent Smith approach again in 2009. Kent labored for a corporation named Sandforce. SandForce was an early pioneer of strong state drive controllers and, as coincidental as it could appear, SandForce’s SSD controllers contained the businesses proprietary ‘Durawrite’ know-how. Durawrite used lossless information compression to cut back the quantity of knowledge bodily written to the NAND flash reminiscence. Information compression. As is the norm within the tech world, SandForce was finally offered to LSI Company, who had been offered to Avago after which later to Seagate. Firms trade palms… and so does the experience that introduced us to the place we’re in the present day.
There was a time when The SSD Assessment was the ‘go-to-‘ useful resource for all the things SSDs, together with enterprise SSD critiques. By means of blame that I can solely attribute to myself, we progressively strengthened our shopper and shopper SSD evaluate portfolio and enterprise reviews light. Truly they dissappeared fully with the final posting approach again in 2018, some seven years in the past. Effectively, that has modified primarily due to a detailed good friend in Jon Coulter. Jon kicked me within the ass and taught me all the things there was to find out about compiling detailed and considerably complicated enterprise and information heart SSD critiques. I’ve been on an enterprise testing roll recently. Imagine it or not, reporting on SSDs (and particularly enterprise SSDs) first hand could be a very satisfying, pleasant and even calming expertise.
So anyway, the inevidable contact was made with Keith McKay of ScaleFlux, an organization that makes a speciality of enterprise SSDs and SoC controllers. Our curiosity was exploring ScaleFlux’s CSD (Computational Storage Drive) 5320 Enterprise SSD which makes use of information compression, a extremely parallel and really low latency implementation of DEFLATE written in RTL with out software program or firmware. This might truthfully be a modern-day model of Durawrite. On the time, nonetheless, I had no clue that Keith’s ‘pedigree’ as an Software Engineer included (however not restricted to) make use of with SandForce, which grew to become LSI after which Seagate.
Digging somewhat deeper into ScaleFlux, we had been stunned to be taught that Hao Zhong, the CEO and Co-Founder, was additionally a key element of early SandForce success. The truth is, taking a fast verify of the ScaleFlux Management Staff as an entire, there isn’t a nook of the business missed with respect to experience. Micron… Marvell…WD… SanDisk…EMC… HP… and naturally, SandForce, LSI and Seagate.
So…. let’s be totally different. We dug into our vault of examined SSDs and pulled out a Future Storage 240GB SATA 3 SSD that we reviewed approach again on August 20, 2011. This SSD incorporates a SandForce SF2281 SATA 3 controller … sure with Durawrite SSD information compression. Would possibly you suppose this nonetheless works? Verify the above picture from our TSSDR Enterprise Check Bench in motion. We migrated our Ubuntu/FIO Check surroundings onto this ‘historic’ SSD and our testing of the Scaleflux CSD5320, in its entirety, was accomplished utilizing this SandForce managed Future Storage SATA 3 SSD. The issues we do proper? If you consider it although… it is a fairly good illustration of a compressible information SSD in motion…14 years after it was saved. Great spot to begin!
The ScaleFlux CSD5320 Gen5 Enterprise SSD. Let’s begin our dialogue with a number of key factors to make sure we’re all heading in the right direction. First off, this SSD is as plug and play because it will get. It doesn’t require particular drivers, software program or software configuration. It may be utilized in 1:1 uncompressed mode, or with 2:1 information compression the place this enterprise SSD actually spreads its wings. The top end result? The ScaleFlux CDS5320 can present unmatched PCIe 5.0 efficiency whereas carrying out as much as 20x storage density, 4x energy effectivity and as much as 6x the endurance of its competitor.
The Scaleflux CSD5320 is a PCIe 5.0 4 channel single port (or 2×2 twin) enterprise SSD that’s (or will likely be) obtainable in U.2, U.3, E3.S, E1.S and E1.L type elements. It has 3.84TB, 7.68TB, 30.72GB, 61.44TB, and 122.88TB dimension variations, and its safety characteristic set consists of AES-256 encryption, TCG Opal 2.02, Key per IO and SED. It is a NVMe 2.0b SSD that’s OCP DC SSD compliant, has latency monitoring, NVMe Skinny provisioned Namespaces Virtualization (48PF/32VF) and OCP Telemetry information.
The CSD5320 homes a two-sided PCB which incorporates their proprietary SFX5000 16-channel Gen5 SSD controller and 16 items of KIOXIA BiCS8 218-layer 3D eTLC NAND flash reminiscence. It additionally incorporates two items of SKHynix LPDDR5x DRAM, one piece being 16GB and the opposite 8GB for 24GB in whole.
Efficiency of the CSD5320 is variable relying on whether or not 2:1 compression has been activated, however even at 1:1 compression, it is a pure Gen5 SSD able to 14GB/s learn and 11GB/s write sequential throughput and as much as 3200K IOPS. When operating at 2:1 compression, there isn’t a competing SSD within the business that may match the efficiency of the CSD 5320 because it reaches 13GB/s write sequential throughput and 1.2 million random write IOPS.
The CSD5320 speaks to underneath 5 watts idle and underneath 18 watts energetic energy effectivity, has person configurable energy states, comes with a 5-year limted guarantee and has 2 million hour MTBF. Checking on-line e-tailers, we will discover the ScaleFlux CSD5320 7.68TB E3.S Gen5 enterprise SSD we’re testing in the present day in and across the $2600 mark. Verify Amazon. Our testing in the present day consists of each uncompressed and compressed modes and are detailed throughout the similar charts.
