As one might expect, the 75 gig GXP's sequential transfer rates are quite similar to those of the 45 gig version... no big deal. The interesting thing here is access time. Though both the 45 and 75 gig drives are rated at a 8.5 ms seek time (and thus @12.7ms access time), results vary. The 45 manages to actually beat its specified access time by a small amount, while the 75 weighs in a bit above. The net result is a difference of nearly 1ms between the two units- quite significant for two drives within the same family!

Likewise, the 20.4 gig 'Cuda ATA turns in transfer rates comparable to those of its larger 28 gig brother (not shown here- for 'Cuda 28 results, please visit the StorageReview.com Database; interestingly, the smaller drives' innermost transfer rate is almost 1 MB/sec faster). Though the drive's access time is impressively low for an ATA drive (only the Fireball Plus LM beats it), it can't meet it's ambitious specified 11.8ms access time.
