Hardware roundup: Sugon loses its IO500 Production lead

The storage benchmark has moved SCNet's Sugon-based results to its Research list. Also in this roundup: MSI's 34-inch QD-OLED work monitor and Sharge's SSD hub.

IO500 ranks storage systems built for high-performance computing, not general supercomputer or GPU performance, and it just moved one of its own top scores off the board it was topping. The committee has shifted SCNet's Sugon-based ParaStor submissions from the Production list to the Research list, restoring Intel-powered Aurora to the Production lead. Tom's Hardware reports the committee's statement, which cites insufficient public architectural detail and limited availability of the underlying file system. The scores themselves are unchanged and still published: this is a change in eligibility, not a newly failed performance retest.

Why IO500 changed the ranking

SCNet submitted two systems at ISC 2026 built on Sugon's ParaStor F9000 all-flash storage and the ParaStor file system. The larger entry, AICS-A, posted an IO500 score of roughly 79,110 from 500 client nodes and 64,000 client processes, about 2.46 times the equivalent Aurora Production result. (IO500's own published entry and Tom's Hardware's report differ by a few hundredths in the last decimal; the difference is not material to the story.) The full configuration, including bandwidth and metadata throughput, is on IO500's own entry page for anyone who wants it.

The committee's statement is narrow. It says the submission did not meet the criteria for the highest reproducibility tier, citing a lack of widely available architectural detail and limited general availability of the file system, and confirms Argonne's DAOS-based system is restored to the top of the Production and Production 10-Client lists. The statement does not dispute the measurement itself. The results remain on the Research list, which is where IO500 keeps systems whose performance is real but whose architecture cannot be independently examined.

That distinction is the reason the two lists exist. Nobody is rebuilding Aurora's storage subsystem at full scale, but DAOS is open source and documented, so its architecture can be understood and reproduced at a smaller scale, which is what the Production list is actually measuring. ParaStor is proprietary and, on the committee's reading, not documented enough to clear that bar. Huawei's OceanFS and SuperFS submissions sit on the same Research list, though nothing in the committee's statement says they were placed there for the identical reason.

Fifth-generation QD-OLED turns up in work monitors

MSI's PRO MAX 341QPXW14G is a 34-inch 3440×1440 ultrawide at 144Hz, and the panel rather than the refresh rate is the reason to look. Guru3D's breakdown puts it on a fifth-generation QD-OLED with an RGB-stripe subpixel layout, the arrangement that clears up the coloured text fringing that has followed QD-OLED since its first generation, along with a Penta Tandem stack MSI credits with roughly 30 percent more light-emission efficiency and a DarkArmor coating the company says is 40 percent deeper in ambient light. Both of those are vendor figures with no independent measurement behind them yet.

The rest of the sheet is desk equipment rather than esports kit: 99 percent DCI-P3 and 97.4 percent Adobe RGB, a claimed Delta E at or below two, DisplayHDR True Black 500, a three-device KVM, 98W of power delivery on the primary USB-C port and 15W on the second, and an OLED Care routine that stretches the mandatory panel-refresh cycle to 24 hours. KitGuru has it on sale in the US at $749.90, with a companion app that maps brightness and volume onto MacBook keyboard keys.

ASUS is taking the same panel class somewhere else at IBC. The ProArt PA27USD and PA32USD are 4K QD-OLED screens at 240Hz with 1,000 nits of peak brightness and motorised calibration hardware built into the chassis, the 32-inch model carrying two 12G-SDI inputs for uncompressed video against one on the 27-inch. The PA27UCDV in the same range drops to 120Hz and trades SDI for two Thunderbolt 4 ports, one of them supplying 140W. Not every new ultrawide has gone OLED either: Philips' Evnia 34M2C5601QA is a 34-inch 3440×1440 at 200Hz on a Fast VA panel with a claimed 4,000:1 typical contrast and a 1500R curve, its own KVM included.

Sharge's Disk Pro 2 gets a removable cable

Sharge's Disk Pro 2 is an M.2 enclosure taking 2230, 2242 and 2280 drives up to 8TB, with a fan, a full-size HDMI port, USB-A, SD and microSD slots, and a magnetic back that snaps onto MagSafe or Qi2 phones. Tom's Hardware's hands-on of the Ultra model states the limit plainly: the interface is capped at 10Gbps, so a modern M.2 drive saturates it on its own before a single video or USB device is plugged in. That makes it a travel hub with storage inside rather than a fast external SSD, and the difference matters most to anyone thinking of using it as a working scratch disk.

Inside that ceiling it measures well, landing second behind Corsair's USB4-based EX400U in PCMark 10 Storage with a Lexar 710 fitted, a useful reminder that responsiveness and available bandwidth are not the same measurement. The Ultra adds HDMI 2.1 at 4K 144Hz and a faster card reader over the Lite's HDMI 2.0, and Sharge lists 1.5W minimum operating power against the Lite's 5W, not a measured idle draw. The bigger change is the removable USB-C cable: a damaged cable can now be replaced without replacing the enclosure, where the original Disk Pro's cable was captive. The new three-position fan switch adds headroom for heavier use, though Tom's Hardware notes that basic, bursty storage tasks on an efficient drive are unlikely to need it, and how warm it runs still depends on which SSD is installed.
