Speed difference between SATA and UDMA Boot Drive

What is the difference in performance between a SATA and a UDMA Boot Drive? Is it that big of a deal to have an ultra DMD/ATA main HD as opposed to a SATA if upgrading the comp now?

My friend just upgraded his comp, and is on a budget. He is leaning towards the 200gb Seagate ATA for $75, as opposed to the same drive but in SATA for $110.

Input?


P4c 3.2Ghz @ 800MHz Northwood / ABIT AI7 / 1GB Corsair XMS-Pro CL2 Pc3200 / 160GB Seagate SATA 7200rpm 8mb cache / BFG-Tech Nvidia GeForce 6800GT 256mb / Antec Sonata case w/Antec TruePower 380W PSU

For performance, almost none. The drive itself is the same. SATA is the interface. It will be able to go faster in transfer than the old PATA (the old flat ribbon) when drive will be able to perform better.

Transfer speed for old ATA has stuck to ata133. SATA can go beyond that speed, but the current drive are not able to fully use the bandwidth of ATA133 and even ATA100.... But when future drive will start to increase throughtput then the faster interface will come into play.

So, the main reasons to go sata are smaller cable for easy cable manadgement, ready for future sata only (it will happen..but when???? optical drives are still at ata33...) or having a little edge in speed..as they can be faster in certain circumstance. But not enough to be called faster..
