| Seagate Barracuda V: Serial ATA | 103 | 13,320 | 83 | 14,834 | 130 | 246 | 108 |
| Seagate Barracuda V: Parallel ATA | 124 | 11,088 | 97 | 12,774 | 125 | 251 | 112 |
Both Seagate drives are 120GB, 7200-rpm preproduction models, but the SATA drive has 8MB of cache while the parallel ATA has 2MB of cache. How We Test: We copy 1.3GB of data (first as one large file and then as a number of folders and files) from one location on the drive to another, time the opening of a 105MB file in Adobe Photoshop 6.0.1 and a number of other operations, and time a find-file operation in Windows. All tests performed on a Dell Dimension 8200 using a 2-GHz Pentium 4 and running Windows XP.
