Liqid, a maker of SSDs for mission critical and performance-hungry applications, plans to demonstrate one of the world’s first PCIe 4.0 x16 solid-state drives at Flash Memory Summit next week. The Element LQD4500 SSD is designed to offer superior sequential and random performance along with an enterprise-grade feature set and reliability. Making this all the more noteworthy is that the drive is based on consumer-grade components.
The Liqid Element LQD4500 SSD is based on multiple Phison PS5016-E16 controllers (with a PCIe 4.0 x4 interface) featuring a custom firmware and carries up to 32 TB of raw 3D TLC NAND flash. Liqid is presumably doing on-card NVMe RAID here, similar to what we've seen in some PCIe 3.0 x16 cards in the last couple of years. Being aimed at datacenters or enterprises, the Element LQD4500 supports power loss data protection and features numerous proprietary technologies from Liqid, including active telemetry monitoring, advanced error recovery, and active thermal throttling.
The fastest Liqid Element LQD4500 SSDs will offer up to 24 GB/s sequential read and write speeds as well as up to 4 million read and write IOPS (sustained random writes are rated at 600K IOPS). Such drives will also offer an ~80 μs read access latency as well as a ~20 μs write latency.
The drive comes in a full-height full-length (FHFL) add-in-card (AIC) form-factor with a one-wide passive cooling system, and is therefore compatible with large systems that need extreme performance and can provide a minimum of 400 LFM of air flow, as the card consumes and dissipates up to 65 W of power. Depending on customer requirements, the drive can be configured for different capacities, performance, and endurance levels.

The Liqid Element LQD4500 SSD will be demonstrated at FMS by Phison, which happens to be an investor of Liqid. There is no word regarding availability or pricing of these drives, but given their performance and capabilities, we're not expecting this card to come cheap.

peevee - Friday, August 2, 2019 - linkSustained random write IOPS correspond to the performance of 1 controller only. Weird.
extide - Friday, August 2, 2019 - linkIt's sustained is the peak of one controller -- not so weird.
peevee - Friday, August 2, 2019 - linkIt is sustained for 1 controller. See that 4M peak write IOPS? 1M peak per controller even assuming perfect scaling at peak.
eek2121 - Friday, August 2, 2019 - linkEven with multiple controllers, chances are you won't get perfect scaling. Random I/O is hard, even for spinning discs.
FunBunny2 - Sunday, August 4, 2019 - link"Random I/O is hard, even for spinning discs."
wow. given that spinning rust is, be definition, sequential and SSD is, by definition, non-sequential (one might say random, but that's not quite right). either way, random and sequential access are essentially the same on SSD. the more channels, the better, of course.
Scott_T - Friday, August 2, 2019 - linkwith a power consumption of up to 65 watts you'd think there'd be a fan on there.

"a minimum of 400 LFM of air flow"
ergo, that has to come from the chassis. let Mikey do it.
eek2121 - Friday, August 2, 2019 - linkMy old 100 watt light bulbs didn't have a fan on those!
hoyabembe - Friday, August 2, 2019 - linkTo be fair, the filament is operating at thousands of degrees C though :D
PeachNCream - Friday, August 2, 2019 - linkIt would be more awesome if my NAND flash chips were operating at thousands of degrees. LED case lighting would be unnecessary as the glow changes from red to white hot. Someone get on this right away!
