Access Time & Transfer Rates
Although the focus of this review is entirely on real-world performance numbers, we felt the need to start out with Access Time and Transfer Rate tests to illustrate some basic differences between the drives being compared here today.
The two purple bars are the two 10,000RPM SCSI drives in this comparison, blue is for all of the ATA/SATA drives and red is for the new comer WD Raptor.
We measured the access time of the drives by conducting 25,000 randomly distributed read requests, the average service time for those requests is reported below:
|
7.4
8.0
8.3
8.4As you can see, the access time improved slightly for the production version of the Raptor, probably due to improvements in the firmware.
|
The production drive allowed for some fairly impressive increases in sequential transfer rates, as is evident by the graphs above and below.
|
44.9The Raptor is now at the top of the transfer rate chart, however it didn't do too poorly in these tests initially either - what about in our real world application test suite?

I have a AOpen AX4SPE-Max Motherboard which has SATA and Raid support. I was thinking about getting 2 of these drives and setting them at Raid 0 for my system drive. I plan on doing a lot of video editing and using a 200GB drive for my A/V content on a regular IDE master channel. Do you see any problems, or have any suggestions with my setup? Thanks in advance...FASE77 - Sunday, November 2, 2003 - link
HiI have a WD800JB and WD1200JB, i'm really glad to see the WD1200JB performing too well in the test, the only thing I don’t like about the drive is that it has no heat sensor! unlike my older Seagate Barracuda drive (ST360021A).
I really hope Western Digital will start embedding heat sensors into their drives soon.

Re: Post on Aug 3, 2003: I have never had a Western Digital drive lose a single bit of my data. Other manufacturers, yes, but not this one.I have a WDC1600JB that walks all over this SATA drive (I bought one and tried it out). Anybody had a different experience? It could be a BIOS setting...

Please compare Raptor single drive performance with two Raptors in a Raid 0 configuration. Please compare also with two PATA drives in Raid 0 configuration.Is there a problem with excessive heat being generated by these units.
Thanks.

But how is the reliablilty going to be, maybe its just me but western digital drives are notorious for being unreliableAnonymous User - Saturday, August 2, 2003 - link
I have a question about write caches: I have read that many SCSI drives do not by default enable their write caches (enterprise may want safety over performance). Are the two 10K SCSI drives in this article run with their write caches enabled to make the comparison more fair? Given the dramatic increase in the SATA drive's performance with write caching, it could be a significant factor.Another comment: WD's drives looks more like the next generation high performance desktop drive, not a low-cost enterprise alternative to SCSI. Perhaps the follow up benchmarks (4 months in the making?) will shed light on this.
