Both spin at 7200 RPM, but the WD Black lists a 32MB cache and CMR recording, so it should hold steadier write speeds. The Caviar GP lists neither figure.

The Caviar GP holds 500 GB, twice the WD Black's 250 GB.

Will the WD Black fit my laptop?

Likely yes if the laptop takes a 7 mm 2.5-inch SATA drive. Check your bay height and connector before buying.

Is the WD Black worth $90.03?

Only if you need a small, fast 2.5-inch drive. For pure capacity, a 500 GB 3.5-inch drive or a cheap SSD gives more for the money.

Can I use the Caviar GP in a laptop?

No. It is a 3.5-inch drive and needs a desktop bay or an external enclosure.

Neither listing gives load cycles or a warranty, so there is no basis to pick one on endurance. Both are older spinning drives; back up either one.
