Storage Solutions can include any medium
suitable for short term & long term usage from Flash
/ Magnetic to Optical for Digital Data Archiving
& Access. We typically advocate Desktop Hard Drive Storage to feature
EIDE - ATA / ATAPI Hard Drives over SCSI. We have
high hopes for Serial ATA to perform
according to Spec - Time will tell!
We advocate 7 Hard
Drive attributes to consider for Desktop ATA Storage Solutions:
Parallel ATA or SCSI. The IDE (Integrated Drive Electronics)
interface is officially known as the ATA (AT
Attachment) specification. We advocate ATA for the money on
Desktop Configurations. SCSI HD's will tend to be faster & cost
more. SCSI is moving to Serial
Attached SCSI for corporate server solutions. Our Standards
Organizations & Trade Associations page has more info worth
reviewing regarding ATA & SCSI Trades Organizations. Serial
60 GB - Minimum.
Rate: ATA/100 (WDC) or ATA/133
(Maxtor). Next generation Serial ATA is
coming! Each Transfer Rate specification is Burst Mode. Sustained
throughput is more important than burst mode, especially when
streaming multiple digital audio & video tracks.
Speed: 7200 RPM vs. 5400 RPM. Faster
is better! SCSI HD's are currently achieving 15,000 RPM's.
- Access Time:
8.4 ms (milliseconds) - Disk access time is an average of time
between initiating a request and obtaining the first data character.
Disk access time includes command processing, seek time and latency.
Fast hard disks have access times of 9 milliseconds (ms) or less. This
is a common speed measurement. Hard Drive performance is influenced by
channel speed (transfer rate), interleaving and caching.
2 MB Cache is typical. Some HD's such as WDC and now Maxtor have
special 8 MB Cache buffers. We expect to see even larger HD Cache in
the near future - 2003.
Note: OK, cutting to the chase: HD
Performance Specs - Compare Mathematical Specifications on any given HD to
find out which one will yield better performance. Access Time equals Seek
Time plus Rotational Latency. HD ATA Specs (Burst
Mode) vs Actual Throughput are NOT the
Since Maxtor introduced ATA/133, their
HD's purchased today will be ATA/133 with 2 MB Cache buffers and 7200 RPM.
Maxtor has now followed WDC with 8 MB Cache Buffers. Special
WDC HD's will be ATA/100 with 8 MB Cache, 7200 RPM. These WDC
capacities range from 80, 100 and 120 GB. WDC has announced 200 GB HD's
due in July or August 2002. Expect to see half a Terabyte (500 GB) HD's in
later half of 2003. And still we wait for Serial
ATA! GB (12/19/2002).

'By 2005, MMC believes, the industry will have switched over to a new
storage technique called "perpendicular recording",
maintaining the steady increases in storage capacity the hard drive
industry has come to expect.' (10/15/2003).
- Hard disk market returns to revenue growth in '03: "New
technologies like the Serial ATA interface are taking off
slowly, according to the market watcher. The report said even though
mainstream chipsets support SATA, only 10 percent of all drives
shipped in 2003 will use the new interface. That's because PC makers
don't see significant performance benefits for SATA and are still
equipping systems with the cheaper drives using the Parallel ATA
interface. SATA will replace the majority of Parallel ATA drives by
2005, the report said."
