Since some of the manufacturers (Seagate, Western Digital) don't even have ATA-133 drives, and based on articles I've read, it seems that the difference in performance between ATA-100 and 133 does not amount up to the expected 133% increase on the ATA-133's behalf - in fact the performance gain seems almost negligible. But what if we compare ATA with SATA(I). I know that everyone has been advised in former threads to go for the SATA if their mobo supports it. Mine doesn't, but I'd buy a controller card if it's worth it. Is it? I mean, besides the obvious fact that it would be better to buy something more modern, and the fact that a SATA controller card (since there's no significant difference in the price) will also have a raid controller, which would allow for later improvement with the addition of another HDD. So how much faster is SATA than ATA ? It would seem that if 133MB/s is not much faster (in reality) than 100MB/s, then 150MB/s couldn't be much faster either. Of course SATA is a different interface. To make the comparison easier, and in an effort of avoiding a debate, as to the differences between ATA133 and 100, let's just make it ATA100 vs SATA; the above mentioned brands, from the which I'd like to choose, don't have ATA-133 HDDs anyway, or at least I couldn't find any in their list of products. The raid function can be neglected as a pro since I'm probably not going to use it. My decision will be based on whether there's a perceptible advantage with an SATA drive in performance. Lower power consumption, ease of use, and other triflings are of no interest to me. I've read a while back amongst the threads but I could only find generalities. Like: SATA is faster, better; but nothing more accurate. Thanks in advance!
SATA was originally operating at 1.5GHz which allowed for a maximum throughput of 150Mb/s, marginally faster than ATA133 133MB/s speed, however the newer SATA 300 interfaces allow for 300MB/s. If you don't have a SATA interface on your motherboard, then it may be better to just stick with a PATA drive rather than buy a SATA PCI card.
ATA (Advanced Technology Attachment)..................... SATA (Serial Advanced Technology Attachment)........... SATA has one extra word in it Serial........... And I think due to this word it works more faster.........
just from my own experience i have gained some quickness in loading windows and the windows install itself when using a SATA drive as compared to PATA.
