  • CF universal Boot Hardrives !!!

    This IC board makes a computer think a CF card is a master boot harddrive!!

    has anyone tried it, I would tink that windows would boot like lightning, and moving around in windows would be instatanius ((sorryspelling)). its on sell for 19.95, and I checked ebay you can get a 1gig cf card roughly 99$. If you install windows (even xp) on this but use a normal harddrive for storage I think this would be great not to mention the power saver here...


    Let me know what you think,

    I have one.. my laptop harddrive boots faster.
    Plus CF cards have a read/write life.

      does everything run smoothly? how does it handle moving files around between folders etc?

        like Custommx3 said, CF cards have limited write cycles, will go bad and corupt after about 5K to 10K writes. That is less than 2 month using XP, if OTOH you are using DOS or other OS, may be!

          glad to know

          Well if thats the case then I guess the best idea for a fast/power saver harddrive is the one everyone else has been saying -> 2.5"laptop hard drive.

          Im waiting for my touch screen to come in, and I've decided to search ebay for a high speed laptop with a broke LCD screen ,since im going to use external screen this is perfect - super savor low cost, complete computer package, 12 volt power safe, and a biult in battery for just in case everything goes wrong(battery dies, fuse problem,ect) when the laptop battery reaches 10-15% then it will self hibernate. Plus all devices can be purchased for usb (using a hub), also a lot of hot swappable laptops have an external cable that will hook up to a floppy/cd/dvdrom drive, which if extended could be connected to the dvd/rom drive and a laptop drive in a case could easily be mounted in a thin small cut out of the dash board, and its powered off the cable it self. this sounds like the most greatest idea i could possibly come up with.

          any downfalls to this idea- then please let me know....

            There's another solution. The Creative Muvo2 hack.

            Check it out here : http://www.pcconsultant.com/microdrive.htm

            You'll end with a 4GB Hitachi microdrive for only a fraction of it's value and without worrying about write cycles.

              It's been beat to death in the forums but you could always make the CF drive read only and have the swap file onto another drive with your mp3's. I have a 1gig CF drive and tried to do this but could not get XP stripped down enough to fit on the CF card.

                One thing that has not been beat to death on the forums, though, that I feel is worth mentioning is that there are various types of flash that offer different performances relative to this discussion:

                There is NOR and NAND memories, and of both types you can build them as SLC or MLC. There are certain advantages to using either memory type or either technology depending on what you are doing (trying to get a lot of data into a small space vs read/write performance, vs longevity and reliability).

                The difference between SLC and MLC memories is a data density thing: SLC stores one bit (2 states) per cell and MLC stores 2 bits (4 states) per cell. MLC memories are the types referenced to have lifetimes of ~10,000 write cycles, but SLC memories almost always outlast 100,000 write cycles.

                NOR vs NAND memories are a little more complicated.. NOR memory provides higher read speeds than NAND, but NAND provides much higher write speeds.

                Finding out what types of memory are present in some no-name CompactFlash card you buy is likely going to be challenging, and what's more, some really nice CF cards have all kinds of crazy things they are doing these days (mixing NOR and NAND, adding RAM buffers, etc.) But in general, if you are developing an embedded device for read-only booting, you probably want SLC or MLC NOR memory due to the faster read speed and low rewrite need, but if you want high reliability over the long haul (ie for mp3 storage or similar; lots of updating), you want SLC NAND memory; no question. SLC NAND holds up well.

                  Its easier... how do I know - cos thats what I did but they can be a bit slower than full size drives.

                    Or you could just spend the money and buy an actual solid state hard drive like these, but they are quite expensive.

                      Since you started this discussion in the M/E forum, I've got to state my position on this one. For my money I'll buy a 3.5 ide drive and suffer the power hit. I can buy a faster, longer living drive than an equivalent capacity 2.5 drive for 1/2 the price, sometimes less. And if you mount it properly, it will live just as long as it would sitting on your desktop. That's one place where people often mess up with their car PCs. They try to add absorbtion materials around the drive, or worse they don't mount the pc case firmly in the vehicle. There are four main failure points for hard drives - head to platter contact (can be caused by design issues, dirt on the platters, and excessive G force), failed spindle bearings, failed head rotor bearings, and controller electronics failure. Shock is going to have little or no effect on the the last 3. Most drives have G-force ratings around 15-20 iirc. Unless you're taking your vehicle airborne frequently, frequently involved in collisions or drive through 6" deep chug holes, you're rarely going to see > 1 G in a passenger vehicle, even one with stiff suspension and tires.

                      Having said that, WTF is this discussion doing in the MediaEngine forum?

                        Thank you for reiterating what I always say. People often underestimate 3.5" HDD's. I can understand if you're mounting the PC in a hidden location with supersmall mini-ITX case. People are so quick to tell someone they must use a 2.5" HDD.

                          I know - it gets old doesn't it? I guess another reason for the 2.5" fetish is that some people just have a hard-on for small things (pun intended). The scene with the barbie-doll scale cell phone in the flick Zoolander comes to mind...

                            Me - its was because I ran out of space in the case when the Opus went in - in fact its mounted up side down on the lid because that was the only space just above the mobo avaible.... If I had the room I think I would have kept the bigger size.

                              I'm running from a CF card. I want to have me system be #1 small, #2 low power, #3 be able to do OBDII monitoring and other things. I want it to boot every time I start the engine and then if I decide to play mp3's I can load up the mp3player and start playing.
