Seagate U Series 9 80 GB IDE Drive

This refurbished 3.5-inch internal hard drive delivers 80 GB of storage over an IDE Ultra ATA100 / ATA-6 interface. It spins at 7200 RPM with a 1 MB cache and offers an 8.5 ms average seek time. The bare drive is suited for legacy desktop systems that require a parallel ATA connection.

Ideal for legacy ATA desktop builds

The drive fits older PCs and ATA-RAID arrays that rely on a 40-pin IDE interface and 100 MB/s maximum transfer rate. It will not suit builders who need a Serial ATA connection or higher capacities for modern operating systems. Buyers who want larger storage or faster interfaces should look at a different drive.

IDE Ultra ATA100 interface decides fit

The single specification that determines compatibility is the IDE Ultra ATA100 / ATA-6 interface. Your motherboard or controller must provide a matching 40-pin IDE port to use this drive. Without that interface the drive cannot be installed.

商品問答

How does the 7200 RPM spindle speed affect real-world performance in this drive?

The 7200 RPM rotation reduces average seek time to 8.5 ms and write time to 9.5 ms, giving faster file access and boot speeds than slower desktop drives.

What practical limit does the IDE Ultra ATA100 / ATA-6 interface impose on throughput?

The interface caps burst transfer rates at 100 MB/s, so sustained reads and writes will stay below that ceiling regardless of the drive's internal speed.

Will this 3.5 inch bare drive fit a standard desktop mounting bay without extra brackets?

Yes, the 3.5 inch form factor matches standard desktop drive bays and uses the usual four side or bottom mounting holes.
