PCIe 4.0 SSD has seen a lot, but it is all PCIe 4.0 x4 channel, the theoretical total bandwidth is 8GB / s, how is this enough?High-performance SSD vendor Liqid has released the world's first SSD Elemnt LQD4500 based on PCIe 4.0 x16 channelBoth capacity and performance are staggering.

This SSD is equipped withFour group PS5016-E16 master with custom firmwareOnly to achieve PCIe 4.0 x16, the internal structure is unknown, it is estimated to be a RAID.

It can carry up to 32TB of 3D TLC flash memory, and the actual available capacity is 30.72TB, 25.6TB, 15.36TB, 12.8TB, 7.68TB, 6.4TB and many other options.

It supports NVMe 1.2.1,Continuous read and write speeds have reached a horrible 24GB/s, random read/write is 4 million IOPS, stable random write speed is 600,000 IOPS, and read and write latency is about 80 microseconds and 20 microseconds respectively.

The overall shape is a full-height full-length PCIe expansion card, single-slot thickness, passive heat dissipation, soAn external wind speed assist of at least 400 LFM (feet per minute) is required, and the power consumption is now 65W.

Three-year warranty, the maximum write amount is 61.53PBW, an average of about 1.9 times a day to writeInto, it is enterprise-level.

The PCIe 4.0 SSD is beginning to emerge, after all, the AMD Ruilong 3000 processor and X570 motherboard platform have been the first to provide support.

PCGN has done a very useful test about whether the PCIe 4.0 SSD will improve the gaming experience. Let's take a look.

The test platform used is AMD Ryzen 7 3700X, MSI X570 ACE high-end motherboard, NVIDIA RTX 2080 Ti graphics card, 16GB Chichi 3600MHz memory, of course, the two main players are the pirate ship Force MP600 M.2 SSD (2TB) And Samsung 970 Evo (2TB), Samsung is chosen because it is one of the top PCIe 3.0 SSDs on the market.

Basic specifications, the pirate ship PCIe 4.0 SSD read and write speed is very strong, Samsung 970 EVO almost, but the price is still more expensive.

The test game has "Destiny 2", "Assassin's Creed: Odyssey" and "Holy Song". The results are as follows:

Boot to the main interface speed

data-ratio=0.22166666666666668

data-ratio=0.22833333333333333

data-ratio=0.22333333333333333

Unexpectedly, in Destiny 2 and The Hymn, Samsung is slightly faster. Only in the Odyssey, PCIe 4.0 saves some face, but the gap is small, rarely more than 1 second.

Game main scene switching speed

data-ratio=0.22166666666666668

data-ratio=0.225

data-ratio=0.235

In the main scene change, the PCIe 4.0 SSD advantage is reflected, but the lead of all three games is within 2 seconds.

In addition, Qunlian Electronics announced that it will showcase the next-generation BGA SSD turnkey solution at the 2019 FMS Flash Summit next week.PS5013-E13T 1113”.

Group connection E13T SSD adoption324-ball BGA integrated package, small size (specific values ​​have not been announced yet),Single-chip integrated master and NAND flash memory, 128GB, 256GB, no external DRAM cache, but rely on HMB buffer technology to speed up, system channel to PCIe 3.0 x2, nominally in pSLC cache acceleration state, continuous read and write speed can reach 1.7GB /s, 1.2GB/s.

Compared with the current 15500MB/s and 950MB/s of the PS5008-E8T solution, the speed of the new generation is only increased by 10-15%, not many, even brighter.The power consumption only needs to be around 1.5W, which is half the current 2.9-3.4W.

In addition, the new solution also supports self-configuring power consumption to meet different needs.

The group said that the E13T 1113 BGA SSD will be available next year and more information will be announced on the FMS.
