    Re: 150 Gig Raptor Review!

    The pic is a bit too small for me to make out the numbers on the graph. What are the beginning and ending speeds, burst speed, and access time? Or, can you post a larger snapshot of the screen?

    Re: 150 Gig Raptor Review!

    That looks damn good my friend. Just about what I was hoping to see. Access time is a tad better than I expected, after reading SR's review. Burst is way up there, which is good given a 16 meg cache. HDTach is a bit ragged but chances are a different stripe/culster combination will smooth that right out. Impressive indeed.

    Do note however that performance with small file sizes isn't much better than a single drive, and this behavior in RAID-0 is very typical.

    Re: 150 Gig Raptor Review!

    so BMW, based on your expertise would you say the benches the gentlemen has shown us has the newer 150GB raptors better than the 74's in the same configuration? Wanting to see if it is worth upgrading my 00FLCO (latest revision) 2 x 74GB raid array to a new 2 x 150GB raid array.

    You mentioned access times better than you expected. Are they still not as good as the 74GB raptors? Same? better?

    Thanks.

    EDIT, ok after seeing the graph myself I see 8.3 for access time. The 74GB can do 7.8. That is a big difference at 0.5. Would this be noticeable if going from 74gb to the new 150? Why do you think the 150 are slower? Can this be remedied?

    Yes. Based on the review done at SR, the STR should begin at ~ 160 MB/sec and taper off to ~ 70 or 80 MB/sec at the inner hub. Access time was slower than a 74, but turned out better than SR's review indicated it should have been. So far, I'm very impressed but the meat is in SR's application level desktop performance, and there it creamed everything, bar none, with room to spare. It set a whole new mark.

    For reference, here is the normal HDTach results for a WD740GD-00FLA2. This firmware, at 7.6 ms, is slightly faster in access time than the previous variants.

    The 16 meg cache in the 150 gig model allows for further firmware optimizations which appear to be largly responsible for the overall improvements in performance despite the slightly slower access time. It is also very likely that disabling NCQ improves desktop performance, which is one thing I've been saying for a long time, expected SR's data to prove, and it did, as you'll see in their performance database charts.

    Thanks for all the responses BMW. I thought the individual who did these tests DID infact disable NCQ? Running on my drives I too got 7.8ms and was dissapointed to see the 8.3 on this graph. Though still faster than normal 7,200 rpm drives it is slower than what I have now.

    You mentioned firmware updates could help this due to the 16M cache. That is what I was afraid of. I mentioned in another post this week about future firmware revisions coming on shipped drives that would be better than drives adopted early on by hasty buyers. You mentioned probably not likely due to the experience they had writing firmware for the 36 and 74 gb drives that the 150GB are already well tuned. I hope the new X drives coming out in a couple months will have slightly better times. They have two months to write a final firmware for that drive to make any changes that may help it out. Being more opted for single user environments could only be a benefit. If I could at least see the same access time as my 74GB raptors or even close at <8ms I would be happy.

    I think the drives will probably be further fine tuned before the X models hit the shelves. WD, by making the X derivative, is, IMO, showing their sensitivity to what the enthusiast market wants, and they intend to deliver. Just an old fart's opinion

    Re: 150 Gig Raptor Review!

    An opinion I value personally. I am going to be patient this time and wait for the X variant. Another two months may very well be worth the wait for these new drives. A raid array of those suckers with a new ATI X1900XTX will surely bring some nice gains to my gaming and benching.

    Incredible. Access time took a hit but wow!
