| 200184 | 2003-12-13 10:43:00 | Hi Not to sure about the new serial hard drives. I would like to update my present dive to 80Gb, and also move into the new drive era “SATA”. My Question is, until I update to a SATA motherboard, can I run one of these drives and if so what cables do I need and are they backware compatiable with order motherboads.. |

| 200185 | 2003-12-13 11:01:00 | there are SATA to ATA converters advialable. don't forget SATA dosn't make the drives any faster. ata drives are still advialable. unless you are useing a really old board why not just stick with ata drives then upgrade the whole lot when you do the rest of the pc. | tweak'e (174) | ||

It does make a huge difference if you are using motherboard that is set up to use SATA though. You can get the full transfer speed out of it where as you can only get up to the 133 on a motherboard that does not support it. ie IDE drives. |

NO. while the speed of SATA is higher (150) the actuall speed of the drives dosn't come anywhere near 133 let alone 150 so you will get minimal increase. the only increase you will get is when the pc requests data that is in the harddrive cache. |

So that means that a program like Photoshop that uses scratch discs (cache) when it runs out of its allocated ram would see an improvement? Cheers Murray P |

| 200189 | 2003-12-14 01:03:00 | no, wrong type of cache. the harddrive cache i was refering to is the "ram" thats built into the hardrive. when the pc requst a piece of data it loads it off the hardrives disks and into its cache and then tranfered via the ata or sata cable to the pc. if the same piece of data is requested it can be pulled straight from the harddrives cache which is faster than reloading it from the actuall disks. the photoshop cache you are refering to is a portion of space on the hardrive, just like windows cache is. |

| 200190 | 2003-12-14 01:43:00 | Plus the cache on a harddrive is normally 2mb,or in the case of slightly more expensive models 8mb.And whats sitting in the cache at any time is only there by guesswork. So any increase by the faster bandwidth is near redundent. Personally i think its about time the entire harddrive concept was done away with,They are the most critical piece of hardware in a system and prone to an early death,and the technology behind them hasn't advanced in any reasonable direction since they first came on the market.Plus no matter how fast they make the transfer speed from harddrive to motherboard the bottleneck is the speed in which the head reads the platter,even now far slower then the ata standard. And for some reason the older slower smaller drives seemed to be far more robust then todays models. How does an 80gig memeory card replacing the harddrive sound? |

| 200191 | 2003-12-14 01:56:00 | the problem is hardrive speeds havn't really increased at the same rate cpu or memory speeds have, hence why raid setups are quite popular. there are some hardrive systems that are made from useing sdram but who can afford even 20 gig of ram ?:| once they get away from useing mechanical parts the speeds should get a lot better. |

| 200192 | 2003-12-14 02:14:00 | >>How does an 80gig memeory card replacing the harddrive sound? solid state hard drives have been around for a while now.. the real question is do you have 4 to 5 digits to spare? Personally what I'd like would be a 5-10gig solid state hard drive for the OS and vmem only... updates to the OS would be like flashing a bios, then programs and files can be stored on a normal hdd... this would make booting into an OS, and the use of system files and vmem like lightning compared to today's snailpace.. you'd just have to come up with a data connection method that's faster than IDE or SCSI.. SATA promises to ramp IDE up to hypertransport speeds though it's very much technically possible, but it's not cost effective and the present bottlenecks still exist |

Dont say NO. I know the difference because I tried both on my machine and it DID make a huge difference going from the IDE interface to the SATA interface using the proper Intel connection. Maybe it did not show much dofference for you but it sure did here. My hard drives have huge caches just for this. |
