Legacy IDE storage
The HGST Deskstar T7K250 is a 250GB 3.5-inch internal hard drive built for desktop systems that still use a parallel ATA interface. It delivers 7200 RPM spindle speed and an 8MB cache for responsive access to operating systems and data on older hardware. The drive is supplied as a bare unit in new condition.
ATA-7 throughput ceiling
The IDE Ultra ATA133 connection caps burst transfers at 133 MB/s, which is the hard limit of the ATA-7 standard this drive implements. Sustained throughput will be lower and depends on the host controller and cable quality. No faster IDE mode exists, so the interface itself is the bottleneck for large sequential workloads.
Host connector and power check
Verify that your motherboard or add-in card provides a 40-pin IDE header and that a Molex power lead is available for the drive. The 3.5-inch form factor requires a standard drive bay and mounting screws. Systems with only Serial ATA ports cannot use this drive without an adapter.

Otázky k tomuto produktu
Is the 250GB capacity the only option in this Deskstar T7K250 series?
This listing is for the 250GB model HDT722525DLAT80; other capacities in the T7K250 family carry different model numbers and are not included here.
What does the 7200 RPM speed deliver in daily use?
The 7200 RPM spindle gives an 8.5ms average seek time and 4.17ms latency for responsive desktop performance.
How fast can the IDE Ultra ATA133 interface actually move data?
The ATA-7 interface caps at 133 MB/s burst; sustained throughput will be lower and limited by the drive's own 7200 RPM mechanics.
