  1. Would be good to add this family of drives. Models: WD40EFRX WD30EFRX WD20EFRX WD10EFRX You should be able to get most of the specs from
  2. Manufacturer: Samsung Family: Spinpoint Released: Notes: laptop drive, released at least 2 years ago but still being produced Model Name (product family): M5 Model Number: HM160HC Capacity: 160 gigabytes URL: Interface: ATA-100 Spindle Speed: 5400 rotations per minute Seek: 12 milliseconds Buffer: 8MB
  3. I'd suggest that some people might still look old drives up for buying decisions. (Have you seen how much used IDE drives go for on ebay?) However, these ones aren't 7200 RPM and the historical data points will be too few (probably just mine) to be useful anyhow. I won't try to talk you out of it. Just mentioned them for completeness, when I came across one.
  4. Most people will buy what's cheap, as they always have done. Back when SCSI devices were much faster than IDE and used 10% of the CPU, what did 99% of PC users buy? IDE. Macs, however, have generally had SCSI built in. Apple users in general are prepared to pay a fortune for an Apple. (iPhone 4 is estimated to cost $US187.50 to make, but sells for 4-6 times that.) I'd wait to see whether Apple's predictions for their own market have any relevance to the wider market.
  5. I know it's old, but it's a whole family that seems to be missing. Manufacturer: Maxtor Family: Fireball 3 Released: ?? Notes: Model Name (product family): Fireball 3 Model Number: 2F020J0/2F020L0,2F030J0/2F030L0,2F040J0/2F040L0 Capacity: 20/30/40 gigabytes URL: Interface: ATA/133 Spindle Speed: 5400 rotations per minute Seek: 12 milliseconds Buffer: 2000 kilobytes Density: 20/30/40 gigabytes per platter
  6. Makes a lot of sense. Ever since the mid 386 era, we've had cache RAM as well as system RAM. If CPU-speed RAM had ever got to the same price/MB as SDRAM/DDR/etc RAM, we'd be using that for everything, but it's never happened. If SSD price/GB remains higher than HDD price/GB, a hybrid is just following exactly the same pattern as RAM has for decades.
  7. Quite right. I should have mentioned explicitly: The 80MB/s I get off a converter is when connected to a Promise PCI IDE card, so the PCI bandwidth restriction is identical.
  8. What's the throughput like? The thing that amazes me is that converters (when they work) are much faster than SATA controllers. e.g. For the drive I mentioned above, 80MB/s with a converter, 63MB/s on a Sil3114-based 4-port controller and 60MB/s on a VT6421A-based SATA/IDE controller. (measured by hdparm under Linux)
  9. Partly lucky. I've got one machine that I bought second hand, running a 1GHz coppermine P3. A couple of years ago, I checked the motherboard specs and saw it was designed to take P3-S chips too, so I grabbed a 1.4GHz P3-S for a buck or two from China. Funny enough, they are more expensive on ebay now! Runs really well. (... even though all the caps have burst.)
  10. How long before that P4 chews through more power than the $2 converter costs? ... A week? (... Not to mention that a tualatin P3 is better than a low-end P4 and doesn't need a fan the size of a mountain.)
  11. For those at the leading edge, sure. For those who just want to add more space on an old machine, or have a drive fail, they're more and more appealing the more SATA drives come down in price and improve in performance. (... given that PATA drives are generally around US$80 for 500GB as WD is about the only game in town.) The 2000 listings on ebay for SATA converters (some of which will be for connecting IDE disks to SATA motherboards, though) demonstrates how much market there is.
  12. I use a couple of old machines as file servers. My criteria for them are cheapness and reliability. Speed is pretty irrelevant, as new drives will saturate even gigabit ethernet anyhow. PATA drives are never as cheap as SATA drives, so, I grabbed a couple of 640GB WD Caviar Black at Newegg for $45 each a while ago. (... after the Micro$oft Bing cashback.) Then, the question was what converter to use. USB enclosures waste space and power and are generally a pain, and one of the machines doesn't even have USB. Similarly, one only has 2 PCI slots, so I don't want to waste one on another HDD controller. SATA/PATA converters are very cheap, but I couldn't find a single review of them anywhere! So, so I thought I'd try some. Here are my results so far. Each cost me about $2 on ebay: A. Bi-directional converter. Marked FZX5003. Black. Square. Plugs into motherboard. Appalling. Has one SATA connector for each direction, so wastes a whole IDE channel for one drive. Then the drive goes down to non-UDMA mode. While I said speed was pretty irrelevant, reducing drives to 1/20 their usual speed while increasing CPU use is just useless. B. Marked HXSP-071218. Green. Plugs into HDD. Flaky. Can work on some VIA IDE chipsets. Hangs whole PC at random when connected to Promise IDE chipsets. Is sometimes detected on boot, or not. Makes drive Master even if it's on the slave position on cable. C. Based on Marvell 88SA8040. Red. Plugs into HDD. Nice! Runs perfectly and gets 80MB/s sustained throughput. Master/Slave is jumpered, but it works. Only oddity is that it causes the controller (Promise Ulta100/TX2) to indicate disk activity permanently. There's one here, but I paid much less. As a number of the commonly available converters are crap, I'd be interested in information on any others. ... Even better if this site would be a comprehensive review of them!
  13. Lovely. Aligns left now. Thanks.
  14. Compared to my other browser, Mozilla (you know, before they renamed it Seamonkey), this is modern. It's also easily fixed. If the table statement is changed from '<table width="100%">' to '<table width="100%" align=left>', it works fine.
  15. Those external drives that SMART works on can just be interrogated through software. Those that don't pass SMART commands through the interface are probably better off not being purchased anyhow. Hopefully, the manufacturers would just tell you. I guess maybe not, if they're throwing their oldest and cheapest drives into the external enclosures?
