Hey all :D
Curious, does anyone know places online that offer good prices on solid state disk drives?
I've stumbled upon these "disk drives" just recently. They sound like what i'm looking for. But I only find them at expensive prices.
Thanks :D |

All I seen on prices on solid state hard drives is around $2000 to $100000 in US dollars. The capacity ranges from 1 gigabytes to 75 gigabytes but these are designed for "Very long-term" replacements for magnetic hard drives.
Look up E-Disk |

Cool! Thanks a bunch :)
These things are really expensive! I'm only looking for something around 2 gigs. Enough for a windows installation and a little more :) |

It won't be to long until they drop down to $500 US dollars or even $100 US dollars.
Solid state hard disk increases the computer speed by about four times or more. Also they last about 10 years under server conditions. Under desktop or workstations they can last even more.
People think that overclocking their computers increases speed. As the processor's speed increases the magnetic hard drives still be at the same speed no matter how much you tweak your computer. The most bottleneck device in the computer is the hard drive. |

totally... that's why i buy the best drives.. though still in IDE format :D
i'm hoping these drives will drop in price soon.... i'd love to pick one up! :) |

Hmm I'll have to think about it. What brand/model is the drive?
hope you don't mind, but I removed your email address above. webcrawlers can pickup your address and start sending you email you probably won't want :D
You can reply here if you want, or use the email button below.
It's a safer way to send out email :) |

oh yeah well i use mail washer hehe and did a little tweek to it it basicaly bounces the email back and tells the sender not valid address i got rid all that porn junk mail **** in like 4 days and now i just get emails from diy and people i know.. : O ) but yuo are right about the spam and ****..

I would agree... i know solid state drives would be a million times faster. |

| Even modern IDE drives usually give faster boot times than SCSI drives because you avoid having to wait for the extra BIOS to initialize. SS drives are just out of this world for speed 100x faster than magnetic drives is the standard figure often quoted so anything HDD intensive really gets a boost. But then you need to look at the capabilities of the bus you are running them off. It's all relative and it's all governed by physics... I dont see that SS drives will be getting much cheaper anytime soon. |

Actually I forgot about that init part. Usually once started, the scsi is faster. It's been a while since I last checked the speed differences though, so I'm not sure how big the actual speed diff is.
need a good old 486 boot time... those things would run through the bios in a second! |

I don't know what you people look at for SCSI, but current SCSI HDDs can run rings around their IDE counterparts.
Having said that the performance of IDE HDDs has made signifcant gains on SCSI HDDs over the past couple of years. |

Try comparing a single Serial ATA drive with any single SCSI drive (excluding the 15,000 RPM Fibre Channel File Server behemoths) and you'd be surprised at the results. In practical terms SCSI has outlived it's welcome as far as modern off the shelf mid-level workstations go. |

Now you are debating on IDE vs SCSI. IDE makes hooking up hard drives very easy. SCSI is very hard to setup. You have to worry about terminating. Many controllers for SCSI are not compatible with today's motherboards and OS. To squeeze all the performance from a SCSI hard drive. You have to be very, very picky on a SCSI controller card. For IDE, just about any IDE controller that you can find can handle 100 megabytes or more.
USB version 2 or Firewire beats SCSI-I at a fraction of the price.

Look into ASUS motherboards for much faster boot times. Don't forget to enable quick boot.

Thats what they say about CD-Rs in the 1990s. They were over $2000 US dollars back then. I e-mailed E-Disks about two years ago when they had only 9 gigabyte hard drives for $2000. |

multiplexor, you can make your own solid state hard drive using standard SDRAM. When the computer is off, you have to design an alternate power source. A NiCd or NiMh batteries doesn't last very long and you have to have your computer on for a few hours so that they can charge. A super capacitor is a better energy storage than a battery. Their life time is very long than batteries.
Solid state drives will come down in price when the need or the want is high. |

Actually, this is not necessarily true, and I speak from personal experience. I recently "upgraded" from a DMA66 IDE drive to a SCSI-1W (20MBs) and took a noticable hit in hard drive speed. Everything takes longer as far as read/write/access is concerned, to the point where I'm considering spending a weekend moving the boot partition back to the IDE drive. :(
And that's to be expected. In fact, an ATA100 drive (all new drives and computer support this, to my knowledge) will likely outperform all but SCSI80 and SCSI160. With an ATA133 drive, only onboard SCSI160 (or a new 64bit/66MHz PCI) will really compete. Then you look and the price difference.... :bigeyes:
I've also had big problems with Windows 2000Pro SP2 with SCSI contoller cards. Tried two upgrades to a SSCI40 card, and got BSOD after BSOD on startup. I finally gave up :bawling:
One of my friends is the network admin for a very large payroll firm in Florida (can't remember the name). Their accounting package apparently has enough problems with large databases and indexing, etc to make the jump from a SCSI160 RAID array to a solid state drive very equitable. :eek: I'll have to pass along the address to this thread :)

Err SCSI-I was the *orginal* 1980s standard. SCSI-I was never available "wide", only 8 bit. In order to achieve 20MB/s you would have either SCSI-2 Wide or SCSI-2 Fast, which both are 20MB/s bus speeds. Ultra/133 isn't a standard, nor will it ever be. ATA/100 is the fastest "official speed" along with the final official ATA spec speed. But being as even the fastest ATA disk can only do about 45MB/s sustained squentail reads(with is synthetic only, not including cache bursts), it doesn't really make much difference. Ultra/133 can only aid slightly in cache bursts, and only one disk manufactor makes disks that use it.
As for speed, SCSI disks are currently available with faster rotational speeds, larger caches, and more capable interfaces. IBM, Seagate, Fujitisu, Quantum all make SCSI disk with rotational speeds of 15,000 RPM along with very large caches. The SCSI interface is also upto U320, not U160 anymore. SCSI disks are also available with sizes available(except for WD 200GB monster). SCSI host adaptors also support more devices per chain - 7 for narrow and 15 for wide(Technically 8/16 but the host adaptor will take on address). SCSI also allows for internal and external devices, along with scanner, networking adaptors, HDs, optical drives, anything you could want.
SCSI is by no means difficult to hook up. Yes, may have to read a paragraph or two if you've never done it before. All SCSI disks these days do SCAM, other then that you have to configure your ID on each device. For termination, you just need a LVD cable with a terminator at the end, no biggy. Almost all cards can do automatic termination for mixing internal/external devices. Most SCSI host adaptors will work any board support the PCI spec they are built on, some RAID controllers can be picky, but that is a different level.
It is true that most people don't need SCSI. The SerialATA is fine for most users. However, SCSI isn't intened for home users, its generally intended enterprise class users, hence the price and features.
As for performance, it really depends on your drives and controllers. And it depends on what your considering performance. There is many factors that come in to place when judging a drives "speed".
It all really depends on your needs, or how much of a geek you are. I personally have a QLogic Dual U160 PCI64/66 card with 1 9.1G R10k U160, 2 9.1G R7.2K U160, and 2 36G U10K U160 on the second channel. Maybe one day I'll get a nice U320 controller with a PCI-X bus(and a matching motherboard). |
