Quantum's Fireball Plus AS 40
Mainstream ATA100 performance @ 7200 RPM

3/5/01 - By  Dave Altavilla

The first two Quantum drives we reviewed here at Hot Hardware, were very high end products with SCSI interfaces and targeted at the Server/Professional market.  Today we are going to look at one from Quantum's "Desktop" offering.  This drive is still targeted at the high end of the segment but with an ATA100 interface, it will most likely find its way to a system the likes of which are configured by many of you loyal Hot Hardware readers.

As we all know, both spindle speeds and ATA interfaces have be driving bandwidth almost as rigorously as the semiconductor technology that is utilized to build them.  These days 7200 RPM drives are commonplace and the ATA100 interface, with its theoretical 100Mb of throughput, is the standard being implemented in every new major motherboard chipset.  IBM was the forerunner in the ATA100 race and their line of Deskstar 75GXP, 7200 RPM drives, have done very well in the marketplace.  The Quantum Fireball Plus AS series of drives that we will evaluate for you here, go head to head with this product family from "Big Blue".  With nearly identical specifications, let's see how they match up and what the Fireball Plus brethren brings to the table.

The specifications in the above tables are fairly impressive with snappy average seek times of 8.5ms and a nice large data buffer of 2Mb on board.  As we noted earlier, this drive's criticals are nearly the same as the IBM 75GXP line.  The only major difference is that IBM has slightly higher areal density at 30 Gig and higher.  The 75GXP utilizes 15G platters and the Fireball Plus AS uses 10G platters all the way up through its 60G drive. 

One final note and simple observation, is the fact that the Fireball Plus AS is a sturdily built drive with one small draw back.  Bring your specs with you when installing this drive or be prepared to break out the manual.  The jumper legend that is on this drive, is not very descriptive and hard to read.  A minor drawback but worth mentioning, for those of you that typically don't like to follow directions. 

We'll draw upon a few test scores later, to show you how the Fireball Plus AS fairs against its very competitive counterpart from IBM.  For now, let's set things up and talk about some of the aspects that you can't read in a benchmark.
