8mb cache really necessary?

[Cynicism]

under what kind of circumstances would this be necessary for me to choose this on a 100gig over a regular 2mb cache?

That is a good question. I am wondering too. I had a disscusion with someone today about it. possible video editing?

Besides the fact that that Western Digital is the fastest IDE drive out there right now. I guess it's for the people who just need to have the latest and greatest. You might want to read up on Storagereview.com, i'm sure they hold the information you're seeking.

I think the 8MB buffer would benefit server applications and large files. Kind of like IDE raid.

Storage Review did some benchmarking on that 8MB cache from WD and some of the benchmarks were performing near SCSI level HDD.... So near SCSI performace without the SCSI price.

It's worth it if you want near 15K RPM SCSI performance, at IDE pricing.... albeit still with IDE's much higher CPU utilization.
The 8MB cache version of the WD1000BB is far and away the fastest IDE drive available, but it's pricey. Still, if you want the highest performing IDE drive out there that'll crush anything else, while offering near 15K SCSI performance levels.

None: That's for desktop applications, for server usage it'll still be handily beaten by any modern SCSI drive as it can't offer the low access times SCSI can.

neccesary? nah

really cool? hell yeah.

and it beats the pants off any other ide drive right now.

dew.

Is any new or expensive technology really "necessary?" Nope, not really. I think we could all live with a GeForce2 instead of a GeForce3 (I know I am). However, it is still the fastest IDE harddrive. Who wouldn't want the fastest IDE harddrive? =)

i was about to nitpick about the access time thing till i read your edit 😛

3-4ms vs. 8-9ms
