Hitachi Intros Two High Capacity Hard Drives
BRISBANE, CALIFORNIA, U.S.A., 1998 OCT 22 (Newsbytes) -- By Sami Menefee, Newsbytes. Hitachi America Ltd. [NYSE:HIT] has introduced two more high-capacity hard drives in its line of 3.5-inch hard disk drives. The firm has begun shipping original equipment manufacturer (OEM) samples and expects production shipments to start in January.

Hitachi packs a lot of data into the small form factor drive: The device is smaller than a VHS video tape and achieves an areal density of 2.93 gigabits (GB) per square inch of disk surface. This density lets the firm's model DK31AH-36 deliver 36.8 GB of storage in a half-height, 3.5-inch form factor case. Model DK32AH-18 puts an 18.4 GB capacity into a 1.0-in. height, 3.5-in. drive case.

Hitachi says its new 7,200 rpm (revolutions per minute) hard disk drives are in the same family as its 12,000 rpm (revolutions per minute) small computer systems interface (SCSI) drive and its 2.5-inch high capacity notebook drives.

Besides the 7,200 rpm disk spin rate, the drives have internal data transfer rates of 150-240 Mb per second (Mb/s). Average read seek times are specified at 7.0 milliseconds (ms) for the 36.8 GB drive and 6.8 ms for the 18.4 GB model. The units have an average latency of just 4.16 milliseconds (ms) and an on-board data buffer of 2 MB in the Ultra-2 SCSI models or 4 MB data buffer in the higher throughput Fiber Channel-Arbitrated Loop (FC-AL) models.

"Seventy-two hundred is a normal spin rate for this class of drive, compared to a desktop drive speeds of 4,000 to 5,000 RPM -- about 40 percent faster than desktops. And it isn't even the fastest drive on the market," a spokesperson told Newsbytes, referring to high speed server drives that spin at about 10,000 RPM.

"Think about your ATM (automatic teller machines) when every millisecond counts as the ATM is checking yours and 10,000 other people's accounts at once," he told Newsbytes. "A drive like this can handle it."

Hitachi has not released prices for the units, which will be marketed to original equipment manufacturers (OEMs).

Yes Clarence, this is my config. I've had no problems OC'ing the boxed 266--it's always been running at 400 mhz. The CPU that Humphrey's selling today is the later stepping, too, so it should be even more reliable.

As usual, it isn't the cheapest possible price, but it isn't too bad either. Especially he does more assembly and/or dickers with you a little, it'll be an excellent way to go. It doesn't perform as well as the OC'd 300a, but you'll always be able to upgrade to that later.

Here are some good comparative benchmarks:

Clarence, my current pricing today showed about a $52 diferential between the 266 and the 300a (cpu only). PCnut may have a better special on the 266 to get rid of them. Because of the small differential it seems likt the CPU of choice has been the 300a. I've built systems based on both recently and the 300a is perceptably e more "snappy". Of cousre it has 128k cache and is running at 464 mhz as opposed to 400mhz for the 266. (never could get the 266 past 400mhz) Haven't run the benchmarks though. IMHO the small incremental cost is worth doing the 300a.
