The State of Solid State Storage

carlmenezes writes "Pretty much every time a faster CPU is released, there are always a few that are marveled by the rate at which CPUs get faster but loathe the sluggish rate that storage evolves. Recognizing the allure of solid state storage, especially to performance-conscious enthusiast users, Gigabyte went about creating the first affordable solid state storage device, and they called it i-RAM. Would you pay $100 for a 4GB Solid State Drive that is up to 6x faster than a WD Raptor?"

    Nope. I'd rather wait longer and have more capacity for less money. After all, I use Windows as my primary OS. I'm used to waiting.

    Truthfully, though, if the price came down, I'd be interested in this for a Windows install, and then install all my apps and save all my docs to an external IDE.

    Agreed. It seems to me that there is still a loooooong way to go with SS storage. IMHO, the people who would need this kind of speed are likely to be editing a lot of video (or some other system-intensive stuff), so therefore would also need tons of storage.

    That being said, I do like the idea, and when they have something that's 300GB+ and solid state, I'd be happy to pay a few hundred dollars for it. It would be quite useful for a media system.

When a hard disk goes bad, I find it difficult to install a 40GB hard disk, when all I need is a couple of gigs. Some of these machines won't even support a hard drive > 30GB.

    could be useful for a triple setup, use your ram and hd as you normally would but all the crap that windows usually sticks in the vcache and swap file could be stashed on the Solid State drive. you could then feasibly dump your ram state into it when doing a shutdown and have an instant "reboot" but as the standard HD still has everything on it if the battery backup fails then you can still do a standard boot. if you use it as a speedy ramdisk too you could build a redundancy setup on your standard HD that mirrors it, (albeit not in real time, obviously) keeping your frequently accessed documents and suchlike to hand but also safe from said power failures

    Before I RTFA, I would have said YES! But it looks like it uses PCI only for power; all data transfer is done over SATA-bus, which becomes the speed bottleneck at something around 150 Mbit/sec. Since that's the case, I don't see why they made it a PCI card at all... I assume the FPGA and the DDR memory require low-voltage power not offered by a normal hard-drive-style 12V molex connector. Meh.

    It just seems to me that the card itself is very bulky, and a similarly-priced RAMdisk with greater storage and a better form-factor is just waiting to be implemented. Oh, and it's not 4GB RAMdisk for $100, b/c you have to purchase the DDR as well :/

    The main problem (other than the limited capacity and price) is the volatility. It has a battery pack, though if the power is out for more than 16 hours (or less, as the battery ages), it loses its entire contents. Which is somewhat precarious.

    A better idea would have been to have a bank of Flash EEPROM built onto the card as a backup device, with loss of power triggering the automatic dumping of RAM contents to Flash, and resumption of power repopulating RAM from Flash on demand/during idle time. Given that it is now possible to fit 4Gb in a Compact Flash card, there is little excuse for not having such a backup subsystem.

  17. We were doing something like this 11+ years ago... by g2racer · · Score: 2, Interesting

    It all depends on the application. I remember 11+ years ago I was a developer on the NY state tax processing project. We were using Sun Sparc 20s connected to Kodak 923D scanners to scan tax returns at a very high rate (something like 72 pages per minute duplex), the barcode information obtained from the tax returns was used to move the returns into a workflow process and the images were copied from a local filesystem over to massive (at the time) fileservers. HD's at the time (even the fastest SCSI drives available) were not able to keep up with the scanner writing the barcode info and images, our custom app processing the information, and moving the images to the filesystem. Our only alternative was to use a "RAM" disk. We stuffed our Sparc 20s will all the memory they could hold (512MB) and created a 256MB filesystem in RAM. We used a thirdparty ramdisk software product for the first release which ran on SunOS 4, but Sun actually implemented a pretty slick ramdisk with Solaris 2 which we used the following year. Benchmarks at the time found that these ramdisks were some 20+x the speed of HDs of that era. I'm suprised that the Gigabyte card is only 6x faster than a HD. You'd figure it'd be more, but I guess they are using SATA as the means through which to get to the "drive", so it may be hitting some physical limitation based on the interface... I wonder if it'd be more cost effective and faster to stick an extra 4GB of memory onto the motherboard and setup a ramdisk device similar to what we had on the Sparcs... Sure it wouldn't survive reboot, but it should only be a hair slower than reading and writing from RAM itself!

    SATA2 is not yet provided, and it's true I was wondering about getting 300MB/s from a ram module that is quite capable of that.

    I was more wondering about some tests missing using databases.

    What better test than a database, say for a small website, with few modifications to the base and the biggest problem being that hdds are a latency hell when the db is waiting for the data to be unstored....

    Under linux, I know I can easily script the partioning at each reboot, and have another script syncing the db to a hdd say every 5 minutes (x% of a max 4 gigs db @10MB/s writing speed... , syncing only the last 5 minutes journal... largely possible if your are not running a Enterprise class website...)

    What would be the results of this test, aka a db with almost no latency and 100MB/s bandwith ?

    Wouldn't that have been more intersting than using it as a pagefile ?
