sata hard drives v 7200 8 meg buffer ide
hi all
how much faster are sata hard drives than ide ones, 1. has anyone seen any test results 2. are they reliable? 3. do they heat up as much as ide ?? 4. any other comments |

Some of the SATA drives are the same as the EIDE ones from the same manufacturer except for the interface. The newest, fastest drives are coming out in SATA but just being SATA isn't enough to make a performance difference in itself. There are very fast SATA drives. Just being SATA is no guarantee of high speed. JT |

I read this on SATA Drives, that there are not much faster than ATA 133, but
that they are less CPU intensive than the ATA drives..... "chris" wrote in message ... hi all how much faster are sata hard drives than ide ones, 1. has anyone seen any test results 2. are they reliable? 3. do they heat up as much as ide ?? 4. any other comments |

hi all how much faster are sata hard drives than ide ones, The thruput from any drive is determined by how many magnetic bits pass the head. The packing of bit/inch has about reached a peak. The only to way get more past the head is increased RPM for the drive. A few drives are offering 10,000 RPM, but most are just SATA electronics applied to the old EIDE drive. 1. has anyone seen any test results THe SATA interface is at 150MB, but no drive yet acheives that rate. 2. are they reliable? Should be no different than older EIDE drives. 3. do they heat up as much as ide ?? With the same mechanical systems, the heat is produced mainly by motor drive windings and bearing friction. No reason to expect any thing different from SATA drives. 4. any other comments ATA133 is mostly a marketing hype. Most drives can not exceed the ATA100 spec. Having a single fewer conductor cable is a advantage. In addition there is no need for master/slave drive designations. SATA is the wave of the future, but at present it doesn't offer any great speed advantages. Virg Wall -- Any sufficiently advanced technology is indistinguishable from magic. Arthur C.

The CPU usage is not a function of the drive or SATA, but how good the
controllers are. They are, overall, about the same for controllers from the same manufacturers whether SATA or not.

In message Trent©
did ramble: 10,000 RPM...8 meg cache. If you noticed a difference when going from a 5400 rpm drive to a 7200 rpm, you'll notice a difference when going to the Raptor. Yup yup, most definitely. The confidence warranty alone is worth the change. Agreed, that is the factor which sold me on this drive, and I intend on upgrading a few other systems as their motherboards are replaced to support SATA. |
