Castle unleash Iyonix UDMA100By Chris Williams. Published: 25th Apr 2003, 09:13:34 | Permalink | Printable
Disc read speeds up to 100MB/sCastle Technology have today sent forth the marvellous news that they've finally implemented and enabled UDMA100 technology for their Iyonix range of XScale powered RISC OS computers. All Iyonixes will now ship with UDMA100 as standard and existing Iyonix users will be sent a free upgrade pack over the next few weeks, we're told.
So, UDMA is the name and hard disc access speed is the game. With UDMA100, the maximum theoretical hard disc access speed is 100MB/s although exact performance relies on a hard disc's model and make. Castle quote typical in-use speeds of 45MB/s and this, to be perfectly honest, tears the legacy RiscPC IDE bus to shreds which can only manage around 1MB/sec (4MB/sec with a third party IDE card, if you're lucky). Apparently "considerable work" has gone into weaving this new technology into the ADFS module in RISC OS 5.
Iyonixes originally shipped with UDMA100 based hard discs even though at the time the hardware couldn't take full advantage of it. Now of course, five months after the Iyonix launch, RISC OS 5 users can do super fast disc based stuff like load an 80MB sprite file into Paint in 2 seconds flat (Castle's example).
"With UDMA support, hard drive performance is boosted significantly with theoretical read speeds of up to 100MB per second", states Castle spokesman Mike Williams in a press release issued this morning which we're surprised made its way past the spam filters given that the email subject was all IN CAPS.
"All functions which involve hard disc activity are now virtually instantaneous", Mike continues. "All aspects of the IYONIX pc will benefit from a noticeable increase in performance, from initial booting of the computer, to using a wide range of desktop applications, to using the 'C' language compiler, and even when shutting down."
We're reminded that Castle will be attending the Wakefield show this year, parading their UDMA100 breakthrough and USB 'pop-up' printing. Castle's technical director was quoted last week as commenting to Iyonix users that the May Wakefield event will be "interesting".
