Hitachi's 500GB SATA-II Reviewed 309

Posted by Zonk from the big-and-fast dept.
Doggie Fizzle writes "The specifications for the Hitachi Desktstar 7K500 are impressive. 500 GB of disk space, 16 MB of cache memory, and 3.0 Gbps of transfer speeds are about as good as you are going to get in today's hard drives. The only category that might be rivaled is transfer speed, but that would require RAID or an Ultra320 SCSI drive to do so. This BigBruin review matches it up with some Seagate drives to show off its performance."

      For those of us that run servers, rotation speed, seek time, transfer rate, these factors are really not that important. What counts in the trenches is how much space do you have, and how reliable is it?

      Not everyone can afford a backup solution, some rely on raid protection, and others rely on a lucky rabbit's foot. Since I am in the 2nd category, (mirrors on anything that matters) I tend to actually look at cost per gb as the primary factor. If a drive fails, I send it in and get another one and resync the mirror. Every drive I buy has at least a 3 yr (if not 5) warranty. In the end, buying cheap drives is more cost effective than buying good drives, and is a lot more cost-effective than buying say a nice DLT drive and a pile of carts. (tho yes, mirror has pretty poor return on cost because of 50% usable space)

      As long as I don't have to like swap out a drive more than once a year, I'm quite happy with reliability of even Maxtors. (though I still am not confident enough in my raids to install WD)

      That being said, I wouldn't mind accquiring a pair of those 500's, though lately it's been getting a little tricky to find a FW bridge board that supports the really large drives. The last 300 pair I installed, (seagate even!) only one of the 14 bridge boards here would detect at 300. (instead of 128) Yes, they're all ATA6 and have up-to-date firmware, that doesn't seem to matter. WD uses their own "unique variation" on ATA6 for their big drives, so those are really fun to work with, I avoid them like plague.

          Unless the drives support an asynchronous write system, which they do. NCQ will reorder the writes anyway. Latency is primarly a read-side issue, random writes are not as common as random reads.

          You can always improve your seek time by adding more redundant mirrors. If we apply the formula the formula seen here [img113.echo.cx] where x is the number of redundant mirrors, we can calculate the value of p which will give us our rotational latency for the mean seek time (hence the 0.5 because we want the 50% point for seek times).

          Using this you can get 7200rpm drives to easily outseek a 15000rpm drive by using 4 or more redundant sources, and it's still cheaper for the same capacity, AND more failure tolerant.

          This is why RAID always wins. Quantity has a quality all its own. SCSI used RAID to defeat the SLED concept in mainfraimes, commodity drives are doing the same to SCSI, by playing with the same rules.
    • Why not just get 2 or 4 GB of RAM (or even more) in your system? That way, anything you ever get from disk will just stay in RAM, so you only have to worry about the latency once.
    • RAID will not increase LATENCY

      You are right, because most forms of RAID decrease latency.

      The more platters you have, the higher the chance that one of the heads is close to the needed data. Thus, for a constant size array, the more disks in your array, the lower your average latency. In other words, four 250GB drives in a RAID will have produce a better average latency than two 500GB drives in a RAID would.

      This is why RAIDs of 2.5" disks are the hot new thing in the storage market. You get a lot more

    These big drives seem destined to be available only with fast IO interfaces. Makes sense when the data object is consumed at high-bandwidth, like HDVD video. Or when many concurrent streams are accessing the data, like a large scale (many users) Video On Demand app. The large storage capacity is reflected in the large transmission capacity: scaling up current data apps to more users or better resolution data.

    But the biggest change we have right now is the ability of individuals to have lots of items of the same old size. People watching their own videos from their own libaries of hundreds of movies. Listening to their own songs from their own libraries of hundreds of thousands of songs. Those apps require huge storage, like hundreds or thousands of GB, for a single person. But they therefore don't require high bandwidth transmission. A 5400RPM EIDE drive is plenty fast enough, but it still needs 500GB capacity (which density might require the higher RPM, but not the faster interface, caches, etc). And for consumers, the overhead for IO bandwidth is a waste of money. As is more than maybe 2 or 3 drives for RAID failover, which also demands cheaper drives.
