Upgrading Compaq F572US HDD
Hi,
Can someone tell me the maximum disk capacity for a Compaq F572US laptop? It now has is a 80GB, 1.5GB/s SATA. 160GB would be nice. Would a 3.0GB/s SATA show any performance improvement at all or is a 1.5GB/s interface still 1.5GB/s? Thanks, Gary |

If I was doing it, I'd look for a drive with power requirements the same or less than the current drive (to avoid potential overheating). You'd also want to eyeball the physical aspects of the drive, just to make sure there is nothing out of the ordinary to prevent it from fitting. http://h10025.www1.hp.com/ewfrf/wc/d...reg_R1002_USEN SATA 150MB/sec versus 300MB/sec cable rate, only helps fill the cache on the hard drive controller a little faster. The sustained (head rate limited) transfer rate, is lower than both of those numbers. The best sustained rate drive right now for SATA is the 10KRPM Velociraptor, at 120MB/sec. The disks in my computer right now, are only capable of 60MB/sec sustained (and that is downhill, with a wind at my back). What you'd want, to answer that question, is some benchmarks comparing various cache sizes on hard drives, to see how much effect the cache has in regular or synthetic (PCMark) situations. In this thread, a Go 6150 chipset laptop is combined with a 250GB 5400RPM drive. So the chipset takes at least a 250. http://www.webtechgeek.com/Tech-Toys...otebook-PC.htm Is your intention to use the recovery CD or DVD, to format and prepare the new drive ? Or are you copying the two or three partitions over from the old drive ? Be careful, as there may be a hidden partition present. If you need to copy stuff from one drive to another, a 2.5" USB SATA enclosure can serve as a temporary way of connecting a new drive. There are also adapter cables intended for temporary hookups as well. You still want the drive to sit flat while working on it, and preferably on a surface where it won't take a mechanical shock. http://www.apricorn.com/product_deta...e=family&id=39 http://www.newegg.com/Product/Produc...82E16812161002 If you're "cloning" the drive, make sure the old drive is disconnected during the first bootup of the new drive. After the first bootup is complete, then you can connect the old drive again if you want. The OS gets confused otherwise (I learned this lesson the hard way, and had to clone all over again, because I didn't know how to fix it). Have fun, Paul |

Thanks, Gary It should be able to use the largest 2.5" drive you can find, such a drive would be SATA300 instead of 150, and newer drives are faster than older ones due to higher platter density so yes SATA300 are faster on average but not specifically because of the difference in transfer speed ability. Rarely you might find a system has a bios bug that interferes with use of high capacity drives, in which case you would flash a newer bios. |

If I was doing it, I'd look for That is what I thought. The Sweet Young Thing at HP said 120GB was the largest but I think she was confused. 120GB is the largest HP sells the 572 with. Capacity limitations were one of the things I though SATA had gotten rid of. SATA 150MB/sec versus 300MB/sec cable rate, only helps fill the cache on the hard drive controller a little faster. The sustained (head rate limited) transfer rate, is lower than both of those numbers. The best sustained rate drive right now for SATA is the 10KRPM Velociraptor, at 120MB/sec.

What you'd want, to answer that question, is some benchmarks comparing various cache sizes on hard drives, to see how much effect the cache has in regular or synthetic (PCMark) situations. Interesting. I would have thought the 3GB/s would mean more than it does. Is your intention to use the recovery CD or DVD, to format and prepare the new drive ? Or are you copying the two or three partitions over from the old drive ? Be careful, as there may be a hidden partition present. My intent is to rebuild the OS. I might "upgrade" from Vista to XP in the process. Judging from the experience with the OS rebuild for our desktop I don't want the laptop down for an extended period if (when!) something goes wrong. Building the new OS on another disk rather than reformatting or partitioning the existing one is a good alternative given the cost of disks nowadays. I always have the existing disk for backup. Gone are the days when a rebuild was feeding Windows, Reader Rabbit, Ami Pro, and TurboC++ into the floppy drive. I'm rebuilding the desktop OS on an old disk. It took a week to get XP installed due to SATA driver problems. We couldn't afford to have the system down that long. I don't really need a larger disk (80GB). I have 3TB between the file server, desktop, and externals. Its just that, at first glance, 160GB drives were cheapest. Have fun, Oh yeah. Paul |
