I've had a very difficult time finding performance data on the 1.8 inch 5400 RPM hard drives offered by lenovo for T4x0s. I think they are produced by Toshiba, because that's the only company online that describes 1.8 inch hard drive products. It seems everyone is happy with the speedy performance 1.8 inch SSDs offer, but I haven't heard anything about the 1.8 inch 5400 RPM drives. Toshiba gives these specifications on MKxx29GSG SATA 1.8-inch Series of Hard Disk Drives.
Track-to-track Seek 15ms
Average Seek Time 3ms
Rotational Speed 5,400 RPM
Average Latency 5.55ms
Buffer Size 8MB
But I'm hoping to hear from actual T4x0s owners, how does the performance of the 1.8 hard drive compare to 2.5 inch 5400 RPM drives? Do the 1.8 inch drives suffer from higher latency compared to 2.5 inch drives, or does the small size actually reduce seek time? Thanks.

The 1.8" hdd's are extremely slow.

The SSD drive in the T410 is made by Samsung, not Toshiba.

I can tell you that from my experience, a 1.8-inch hard drive makes everything VERY slow to the point that it is simply impractical... You're just wasting time waiting and waiting and waiting.
However, if you swap it with a 1.8-inch SSD hard drive...
1.8 inch hard drive performance? (T400s)
