30,002,765 operations a second

Held by FlashNexus FN8200. Set 2025-02-25, and has stood for 581 days. Written down here 2026-09-22.

Every other number on this page sits on top of this one. A machine can only compute with what it has been handed, and handing it the data is the job of the storage underneath - which is why the council measures the thing that is hardest to make fast rather than the thing that looks best. The SPC-1 workload is, in its own words, predominantly random: small reads and small writes to unpredictable places, the shape of an order system or a mail server, and the opposite of the long tidy streams a disk is good at. The climb is the part worth looking at. In November 2016 the best anyone had submitted was a million and a half operations a second; the figure passed ten million in 2019, twenty-one million in 2020, and stands at thirty million today. Twenty-fold in nine years, and unlike the database transaction record elsewhere on this page, this one was not won by renting a thousand machines: it is one storage system, audited by an independent party, published with its price attached.

That description was written when this frontier was opened, on 2026-09-22, and is never rewritten. Where it and the number above it disagree, the number is the reading and the description is history.

What counts

The largest figure in the Performance (SPC-1 IOPS) column of the Storage Performance Council's SPC-1 and SPC-1/E results list - input and output operations a second, on the council's own SPC-1 workload, by any storage system it has published. SPC-1/E is SPC-1 with the energy use measured as well, so the two are the same performance measurement and belong in one column. The list is ordered by submission date and not by performance, so the reading is taken by sorting the column in a script and never by reading the top row; it is also paginated twenty-five rows at a time and a reading must fetch every page. Two rules belong on the number rather than under it. Every row carries a status, and a row reading "Submitted for Review" counts: the council's review window has long passed for the two rows that carry it and the council ranks them anyway, putting the record holder at rank one of its own Top 10 by Performance page, so this follows the publisher rather than substituting a stricter standard of its own. And every row on the list today is SPC-1 Version 3, whose scores are not comparable with the versions before it; if a version 4 ever appears in the Version column this frontier needs a decision before it needs a reading.

What moves it

A vendor submits a result with a higher figure and the council publishes it. Submissions arrive a few a year rather than to a conference calendar, so this can move in any week - and the record has moved in 2016, 2017, 2018, 2019, 2020, 2021, 2023 and 2025.
