(Please note your Mac system details (model, CPU speed, etc.) when sending reports. If you can also include real-world tests like time to boot, time to duplicate a large file or folder with many files, etc. - see my drive reviews for examples of tests, etc. I use.)
Love the site!
I am sending you this report from Quick bench. I just bought and installed 2
of the special edition Western Digital 100 GB with the 8MB cache. (He later wrote his system is a Dual G4/800 Quicksilver with 1.5GB of RAM-Mike)
I am using a Promax 66 ATA controller card but I have ordered the Sonnet
Tempo 100 and I will report again when I get it (everyone seems to be sold
out of it).
[I would have mounted the drive as a slave on the onboard IDE bus vs the ATA/66 PCI IDE card personally. This guide covers doing that for those that are not familiar with the process.-Mike]
Here are numbers from my old Maxtor 7200rpm 60 GB and the new WD drive.
(I asked if he could send screenshots of the graphs which are easier to compare/digest than text numbers alone-Mike)
(Thanks to Matt Chojnacki for graphing the original text results)
(He later sent graphs from Quickbench for the WD 100GB/8MB Cache drive tests, but had removed the Maxtor drive and didn't take screenshots of the first tests.)
With an 8MB cache in this drive, the ATTO Tools benchmark's limit of 8MB I/O sizes would not be a good benchmark. (I use it for many drives with 2MB or less caches, as well as other benchmarks and real world tests.) The read curve looks like it has a cache spike (up to about 512KB), but look at the flat curve for writes all the way to 8MB.
I asked the reader if he could also send real-world tests like time to duplicate a large file and a folder with many files, boot times, apps launch times, etc..
Western Digital Links Since these drives ship with no documentation or jumper settings info here's some links you may find useful:
After a phone call to WD, they say this drive marking does represent the 8MB model (despite a mfr date of July 18th, 2001 - several months ago)
Model No: WD1000BB-75CHE0
I do not have any model numbers from the 2MB cache model to verify if the above is unique to the 8GB model.
I welcome other owner reports on this drive. There was a previous page where with some WD 100GB (2MB cache model) IDE RAID performance reports. PC site StorageReview recently reviewed this drive (tested in PCs of course). (I wish there were Mac versions of the wide array of disk test utilities on the PC.)
