Want fast SATA HDD, recommendations?

Their "Advanced disk format" drives use a 4KB physical sector size, but still use a 512 byte logical sector size. Many of their drives lie to the os about the physical sector size, claiming it's 512 bytes. If you use one of the garbage drives, you must align all partitions, files, meta data, etc, on 4k boundaries (which can be very difficult), or you will have pathetic write performance. My opinion, do not buy anything from WD, unless you know it doesn't use their "advanced disk format". Regards, Dave Hodgins The bad news is, there was an announcement, that the "industry" as a whole was switching to 4KB sector drives. So soon, you won't be able to escape them. And with the consolidation, and the loss of Hitachi, Samsung, and the like, there really won't be a lot to choose from. It'll be a "diet of garbage". AF gives higher aureal density so greater drive capacity. Yes, it's the way of the future for mechanical drives (I believe all SSDs are 'AF'?) but it's still a PITA for XP users, especially when I had to find out about it the hard way. I'd read about AF, that it was 'coming' a long time ago but when I bought my 2TB 'EARS' WD HDDs there was no mention that they were AF on the site I ordered them from. I had to dig deep into WD's PDFs to find it. (Other than the tiny writing on the drive that I missed at first which said to use a jumper if using with XP and single partition. I'd never use a single 2TB partition anyway so ignored it when I saw it.) However, for now it'd be nice to find a smallish fast non-AF HDD for my tower boot drive. Cheers Paul, great to see you still prolifically posting here. I often come here just to read your posts. :-) -- Shaun. "He who fights with monsters might take care lest he thereby become a monster.

It has four SATA trayless removable HDD 'docks' (for want of a better word) that I use to facilitate transferring data and doing backups. It works well. (System is an Asus P5KE-WiFi/AP board with a QX9650 CPU and just 4GB of RAM [running 32-bit XP]) I have a few 2TB HDDs that get moved between USB docks attached to laptops and this machine. The USB docks are fine for writing moderate amounts of data but are rather slow for large amounts. That's where the tower comes in. Anyway, I want a new (mechanical) boot drives for it. The old Seagate 500.10 isn't the greatest these days and frankly I don't need 500GB for a boot drive. However looking at new ones that seems to be the starting size. Frankly all I need is ~100GB. I toyed with the idea of a 2.5" drive but they're generally slower and would cost me more than a 3.5" 500GB drive anyway. I'm not rich but would like a fast, reliable drive. Single-platter would of course be best, faster to spin up etc. I'm contemplating a Western Digital Caviar Black WD5002AALX. WD don't seem to want to tell you how many platters / heads each of their drives has, unlike Seagate. You need to infer it from the weight / ready time in the specs pdf that you can download. I've Googled trying to find a review of smallish 7,200rpm desktop HDDs but, from what I could see, all of the hardware sites are only interested in benching SSDs these days. So what say you? Is the Western Digital Caviar Black WD5002AALX a good choice? I can get a Seagate 500GB 7.2K HDD for about 3/4 of the cost of the WD but the WD has a 5 year warranty and recently I've moved to WD drives as the Seagate agents for New Zealand don't seem to be very aggressive or competant or something, most stores seem to have lots of WD stock and little Seagate stock. Input appreciated. I want a small, fast and preferably cheap boot drive for my tower / server / archive machine. TIA, Seems pretty simple to me. If you want a fast boot drive then buy a small SSD and use it for just the OS and minimal application. What would having a spinning platter gain you over an SSD besides slower speed, more power consumption, heat, and noise? I get along in my main i7 machine with an 80gB Intel drive and IIRC the actual OS installation along with all of my high-priority applications, swap file, hibernation file, etc took up ~24gB. The system has a 2tB data drive with three partitions but it doesn't need to be all that fast so I get along fine with a 'green' drive there. In your situation, I'd leave the 500gB drive right where it is and use it for data and store images of the SSD on it for backup. Thanks John, I agree that, in a perfect world that's the way to go. Alas, I'm an invalid on welfare since an accident in '95 left me with spinal injuries. SSDs are still out of my price-range. Ironic LOL In fact this drive I was planning on getting is off the menu for now. Times got a lot tighter of late, I'm selling my collection of old ThinkPads, my only hobby, machines that I bought cheaply and refurbished. Can't afford to drink, smoke, socialise, go visiting (ergo have lost the frinds I had), eat decent food. I gave up on TV a long time ago and now it seems my one hobby that gives me pleasure has to go. (I used to bould desktops, for myself and friends, and was a rabid overclocker. However when electricity got so expensive I switched to working with ThinkPads for my hardware fix.) Sucks to be me right now. Middle of winter, unheated house, many layers of (old) clothes, typing in fingerless gloves at 2pm, trying to decide which ThinkPads will net me the best money and be the least loss.

XbitLabs.com did comparative reviews of hard disks last February and December, and they seem to test hardware better than anybody else does. I've had no problems with 4KB "advanced format" drives and simply used a partition alignment tool (Gparted, downloadable with a self-booting CD ROM image). Thanks Stooges. See previous posts for my experience with AF. I checked Xbit before I posted here but didn't find anything relevant. Must look again. I agree, they're a good site, my first stop for tests, opinion etcetera. -- Shaun. "He who fights with monsters might take care lest he thereby become a monster.
