First, the Seagate 7200.8's and the 7200.9's have a 8ms access time. Second, I was under the 7200.9 wasn't suppose to be released until Fall 2005 at the earliest so it's not out yet. It's going to have 16MB cache and top out at 500GB. Third, even the older 7200.7's have an 8.5ms access time so I don't see the new drives getting slower by a 2x margin.
Yes, I made a mistake on the model number. It is in fact a 7200.8. You are correct on that one, too bad you spent the rest of the post proving model numbers are the only thing you understand about hard drives.
Seagate's have a claimed average
seek time of 8.0ms. This is NOT the same as access time. You have to add average latency to average seek to calculate average access time. Average latency for a 7200RPM drives is 4.17ms added to 8.0ms gives a claimed average access time of 12.17ms. The reason why I say claimed is because hard drives practically never perform as well as the spec, and Seagate in particular is notorious for not even coming close. Mine tests out around 15.7ms which makes it one of, if not the slowest desktop 7200RPM drive ever by average access time. Storage Review tested a SATA version of the drive and did slightly better, though not much:
Seagate Barracuda 7200.8: 15.0ms access time
"The Barracuda 7200.8 turns in a measured random access time of 15.0 milliseconds. Subtracting the standard 4.2 milliseconds to account for the rotational latency of a 7200 RPM spindle yields a net measured seek time of 10.8 milliseconds. While Seagate's claim of an 8 millisecond seek time is rather ambitious for an ATA drive,
a measured score of nearly 11 ms is undeniably lethargic by any measure."
To give you an idea how slow that is, 15.0ms is the 4th slowest drive SR has tested in their almost 4 year old testbed, and is slower than some 5400RPM ATA drives they have tested. From SR's conclusion:
"Unfortunately, while the capacity is there, the performance is not. The 7200.8 lags significantly behind the latest offerings from Maxtor and Hitachi in both single-user and multi-user instances."
I hadn't read this review before I bought the drive, so I was unaware of the poor performance. But since I bought it for only storage and the price was good, the turtle speed doesn't matter to me.
The 7200.8 series is a slow drive by modern standards. Just because you seem to be happy with the performance, doesn't mean the drive performs well.
