Some of the top large-size SATA models been extensively reviewed over at bigbruin
. The review focuses around the Maxtor DiamondMax 10 300GB SATA model (there is also an ATA133 model) with a whopping 16mb of cache. The majority of desktop HDD today have 8mb cache, 2mb in cheaper models. The first few pages describe the physical characteristics but towards the end there are some very good benchmarks. The drive fares quite well, and is compared to three other models: A Hitachi 7K500 500GB, a Seagate 7200.7 200GB, and a Seagate 7200.8 200GB. It tends to be fairly neck-and-neck with the 500GB offering from Hitachi, and some cases outscores all three drives, especially in buffering - That 16mb of cache does come in handy. Those of you wondering whether or not a SATA drive is worth switching from PATA can put those worries to rest. The drive named as well as the other models show that SATA150 drives are coming of age and can truly put PATA to shame.
