i-RAM Pure I/O Performance

We begin our usual hard disk drive test session with Intel's IPEAK benchmarking utility. We first run a trace capture on Winstone 2004's Business and Multimedia Content Creation benchmark runs to catch all of the IO operations that take place during each test. We then play each capture back using RankDisk, which reports back to us a mean service time, or average time that the drive takes to complete an IO operation.

Pure I/O Performance Comparison (Results in IO ops/second Higher is Better)
IPEAK Business Winstone 2004
IPEAK Multimedia Content Creation Winstone 2004
Gigabyte i-RAM (4GB)
4347.8
1754.4
Western Digital Raptor (74GB)
735.3
467.3


Not too surprising is the i-RAM's dominance here, performing almost 6x the speed of the Raptor in the IPEAK trace of Business Winstone 2004 and 3.75x in the IPEAK MMCC trace.

Absolutely incredible I/O performance is to be expected from the i-RAM. The question is, how does it translate into real world performance?

    I must have 50 sticks of unused PC100 and PC133 SDRAM.
    Something like this for old RAM would be a value, (for me).
    Does anyone know of an adapter that would take, lets say, 10 sticks of SDRAM and give me an IDE or USB connector?

    I spent a little time looking for this and not even the manufacturer lists it on their site

    It was on Gigabytes site as I looked today and the past month while making the descion to get it.

    There's been a lag while retailers get rid of the v.1.2 and Gigabyte sends out the v1.3 cards.

    I just got one of the new ones and will use it to run my FTP server application. I have 14 or 16 drives connected (6TB) to the server and previous reviews by others have pointed to the performance increse from the FTP app. searching and retaining the disk locations.

    since I just got it I am not %100 on the reality, and the real benifit will be realized by the client seeking a file from the server. Using it for MS SQL Server is also a great idea. Other than that I haven't heard any real world uses, I mean users might be able to load Doom faster, but this device seems to be a bit expensive for most.

    Also this card is bigger in area than most video cards, so if your box is crammed w/ wires or liquid pumps and resivours. The logistics of getting say 2 video cards and the RamDisk in a midsized case are pretty obsurd. Plus you need a fan or 2 in there to swirl around the heat generated by 3 heat monger cards) ...There goes more money in a bigger case.

    For the general user, I would go with the new Raptor (the clear one) if you want to compromise speed, size and cost on a rational level.

    Peace all

    The simplelist and best use of the i-ram is to store the "Temp DB" for SQL Server. MS SQL Server constanly writes to this database in most larger installations. It is temporary and by definitions does need to exist after reboot. (Alas SQL Server does not/CAN NOT keep this database in RAM) So on reboot a script will need to verify that it is still formatted and the appropriate file system/ files exist -- copied from the hard disk. SQL Serve is fussy about hardware so it masquerading as a disk is perfect.

    In an hour on google I can't find someone to sell it to my boss to try it out. sigh.

    My prediction is a 5-10% boost to overall throughput on a SQL server installation with lots of "temp DB" activilty -- well worth the cost of the ram chips.

    I've been keeping an eye on ram disks for a little while now, but other than software they are just too expensive. The earlier post that had links to them (both flash and DRAM based disks) was the same stuff that I found. More recently I had been relieved by the availability of 64bit Systems and OSes with more slots/address space for ram and thus bigger ram disks. But it still really burned me that someoune couldn't make something really cheap that didn't rely on a big fat motherboard (which still has only so many slots, but admittedly faster).
    This qualifies. The second I heard about this while reading computex stuff I said to myself: Self, this thing only takes power from the PCI bus, therefore it would be a trivial thing to buy some PCI slots (like 8) and wire them for power, then raid or jbod these together and get one heck of database drive at a fraction of the cost of other solutions, and scaleable at that (I can start out with 2 or 3).
    I also think it would be a nice (and easy) thing for them to put it in a 3.5" form factor with both molex and/or 3.3v standby loopthrough (through a pci dummy card or something). And yes 8 slots would be much more saleable, understanding that the mem controller may not support that (though some sort of bank switch would work since you have time to wait for the SATA or SATA2 bus, 3.5 form factor would get difficult with 8 slots though).
    The situation that got me looking at this stuff is I have a mysql database (tested others as well) that has to do a table scan each time I do a query since it is a '%something%' query (loading web logs and running user demanded reports on them) The database is at around 4 gigs already (about 6 months worth, including 0.5GB packed indexes) and the report takes about two minutes (2 15k drives in RAID 1, not bad) But I still have to run it at night and make a summary table. (maybe a database with multithreaded partitions or grid would do it, but how much does that cost???!?) Anyway, my 2 cents (sorry for the long post). I'd really, really like to know what benchmarks say the latency for this thing is.

    For a mass product gigabyte needs to add.

    8 dimm slots
    SATA2

    Let's hope they do it fast...
  • ybbor - Friday, July 29, 2005 - link

    What would happen if you stored a SQL database on the drive... wonder what it would do for database proformance benchmarks.

    you would probably back up to HD every night, or cluster with db on HD for data integrety
  • Chadder007 - Friday, July 29, 2005 - link

    They should have went with a SATA II capable interface instead of regular SATA since it has much more capable bandwidth sitting there waiting to be used. Also the 4 gig of mem only hurts it a tad too.

    Now just as a thought to scary uses for the i-RAM. Law enforcement will hate these things. Peadophiles will have instant access to wiping there files without a trace, terrorist won't have to worry about the good guys being able to track their files.

    Nope, pedos have a compulsive urge to collect stuff, 4GB wouldn't even come close. Besides, if the pedo was thinking that far in advance, there are plenty of already-existent technologies far more secure. When the cops come busting down someone's door, do you think they'll saw something like "freeze, don't move, unless you prefer to go over to your computer and wipe data!" ? Then again, general ignorance about the need to keep the evidence battery charged could be an issue.
