Nice 450MB/sec average read speed on that RAID for mechanical drives!

Mechanical shmechanical, yeah, but remember there's another 2.7TB tucked in behind ...

I do love the SSD on my tablet, which gets a similar WEI just by it's lil ol' self.

Your 8.6ms seek time is 86 times slower than many SSD seek times. hehehe, seek time does matter. Although much better than many regular "mechanical" drives.

By similar, you mean 140-160MB/sec transfer, not your nice 400MB/sec. It takes a RAID array to get 400-500MB/sec transfer speeds on most SSDs (unless we're talking multi-thousand dollar enterprise-level SLC versions, then may be up to 250MB/sec max for one drive).

Well, yeah, there's no head to move around . No, I meant actual Windows 7 WEI, 6.2, and check this out - if I disable ALL caching, both on the Intel Storage Mgr and in the Windows device settings, check out my disk WEI! What's up with that???!!

I really fail to see the logic behind the drive assessment ...

Yeah, WEI isn't a reliable gauge. Hypothetically, you have an MFM drive from 1980 with 200ms max seek time and combine it with a 500MB/sec transfer rate, and your WEI score would be 7.something.

Joined in response to this thread. Helpful numbers from production systems-and no flaming about the choices anyone else has made.
The Vertex SSD is the system drive. When I did a clean install of 7100 I skipped the tweaks to see how MS handled SSDs in 7. (I should note that I'm using AMD SB750-from info on the OCZ forum that can cost 50-60MB/s.) I run a pagefile and I run it off the SSD. I added the Velociraptor and Samsung 1T drives for comparison within the same system. (I run AHCI-I haven't compared on 7100, but on 7000 ACHI gave me a 7-10% improvement.)

I included screenshots of my diskmark small file benches. I think that those small file rates and access times account for the feeling that the system is more responsive in regular use. (vs. moving large files, encoding video...)

I think mechanical drives will be around for a lot longer than I once thought. You can really get most of what you need from one. SSDs are just so fast they are fun. That;s why I got mine....just for fun....and it worked.

Regular HDs will be around for a long time. Although netbooks and laptops will probably be 96% SSD in a matter of years(like 3)

I love this thread. I love to look at ALL of them.

You may try posting this in a general help forum. This is a HD performance thread. Someone will help you. Just post in a better spot.

They're perfect for notebooks. It breathed new life into my Thinkpad tablet. For large storage they're just not cost-efficient yet. They'll get there soon enough.
