Gigabyte's i-RAM: Affordable Solid State Storage

i-RAM for Applications
Gamers aren't the only ones plagued by long load times. There are a handful of applications that do take a reasonable amount of time to load that could be benefitted by being installed on an i-RAM card.We tried a wide variety of applications, everything from Office to Photoshop and 3ds max. What we found was the following: for the most part, the majority of applications are as fast as they are going to get on any current-generation SATA drive. We noticed no performance difference loading any of the MS Office applications on a Raptor or on the i-RAM card.
| Application Load Time Comparison (Lower is Better) | |||||
Adobe Photoshop CS |
Microsoft Outlook 2003 |
Microsoft Excel 2003 |
|||
| Gigabyte i-RAM (4GB) | 3.537s |
2.51s |
1.654s |
||
| Western Digital Raptor (74GB) | 6.037s |
2.562s |
1.765s |
||
The biggest differences that we saw were obviously with applications that took a long time to load to begin with, one of the most popular culprits being Adobe Photoshop CS (we didn't have CS2 available at the time of testing).
On a WD Raptor, Photoshop CS took about 6 seconds to load; it's not much when you time it, but it can feel like an eternity when you're actually sitting there waiting for it. The i-RAM cut the load time down to 3.537 seconds, a significant reduction, and very noticeable.
The major issue with the i-RAM and using it to install our applications on it, once again, becomes size. But it is entirely possible to keep a handful of your very frequently used applications on the card, giving you faster access to them.

I think another possible use (besides certain kinds of servers, like mail servers), is for video capture. The size is a bit small, but if you were capturing segments of footage, it might work. And the price could be reasonable.BikeDude - Tuesday, July 26, 2005 - link
"but 32-bit Windows can't use more than 4GB of RAM, including the swap file size."First of all... "Swap file" is a misnomer. We talked about "swap file" back in the Windows 3.1 days when the OS would swap a process' entire memory space to the *swap* file.
These days the OS will read/write selected pages of a process' memory from/to the cache manager (who may or may not elect to use the disk to get to the physical pagefile). *Paging*, not "swapping". Executables and libraries are memory mapped and thus start their lives with all pages firmly on disk (so a big executable won't necessarily load slow, but many small DLLs OTOH just might).
I don't have Windows XP in front of me, but my 32-bit Windows 2003 Standard ed. with 4GB memory and 1GB pagefile certainly doesn't seem affected by the limitation you mention. Enterprise edition can address even more physical memory... Each process is still limited to a 2GB virtual address space though. (32-bit processes marked capable of such will gain a 4GB virtual address space under 64-bit Windows)
I realise that XPSP2, despite PAE, is limited to 4GB physical memory (http://blogs.msdn.com/carmencr/archive/2004/08/06/...">http://blogs.msdn.com/carmencr/archive/2004/08/06/..., but pagefile as well? Nah, sounds iffy.

Without PAE (or something similar), 32-bit OSes are indeed limited to 4GB of RAM. This is what is being referred to, as PAE is limited to Intel and I don't believe it's available on non-Server versions of Windows. (Correct me if I'm wrong, but PAE is pretty much only on Xeons, right?)You're right that it's paging instead of swapping now, but there's really not much difference between the two. Basically, you put data onto the HDD in order to free up physical RAM, on the assumption that the least recently used data that was moved to the HDD won't be accessed again for a while.

Anyway, I've modified the comment to reflect the original intent. If you're running PAE and Server, it's a whole different ball game for high memory systems.Penth - Tuesday, July 26, 2005 - link
Wow, my friend and I talked about the possibilities for these things several times. But at 3x the initial price and not the performance increase I would have expected, the techie in me is disappointed. My wallet is happy though.StanleyBuchanan - Tuesday, July 26, 2005 - link
I wonder what the issue is with RAID that Anand comments on.... seems odd that it would behave differently than a HD in this respect and cause problems...I would love to have 12gb or more... which is enough for Windows XP, a productivity suite, and a modern game... anything more could be run from NAS

Probably something to do with the PCI bus power. Perhaps two of these cards take more juice than the bus expects to provide while on standby.phaxmohdem - Monday, July 25, 2005 - link
I saw someone else posting as well, but I would very much like to see some database performance numbers from this device, as well as perhaps a web-serving benchmark.xTYBALTx - Monday, July 25, 2005 - link
How some FPS benchies?GTMan - Monday, July 25, 2005 - link
I laughed when I saw that line :) A very interesting device and I look forward to where this goes in the future. Your "Final Words" could use a bit of brevity.
