 Posted: Thu Jan 18, 2007 10:53 pm Post subject: Worth upgrading to SCSI? |
 |
|
I've got a SCSI performance question....
I just set up a multi-seat box for my kids. It runs on an Athlon 2000
XP, with 786 MB RAM.
The mobo is a no-name PCI-32 mobo.
Right now, the machine uses a PATA drive, and performance is OK. I do
see slow times to bring up new software, though, especially if both kids
are trying to hit the HD.
I am also obsoleting an old server with some decent 36 GB Seagate
drives, including a 10K (or possibly 15K) Cheetah.
I have an old Adaptec 2940 UW adapter and some cables I could throw in
there.
So.....
Am I likely to see any performance improvements by migrating to SCSI? I
know the advantages of SCSI in server environments, but I am wondering
if it extends to a two user machine.... Especially with such an old
adapter.
I am also concerned about PCI bus saturation; I already have 2 video
cards in there, and I wonder if the PCI bus can stand the additional
traffic of a SCSI adapter.....

first increase RAM to 2 GB (or the maximum the box will take). A SCSI
upgrade might be noticable, but it may not. |

That's all the RAM I got... 3 slots, 256 MB in each....
I don't know if it's worth the pain of a SCSI upgrade...

If the motheboard won't take more than 256/slot then it is probably
not worth upgrading. You'll just trade one bottle neck for another. |

You have the goods already so why not try, see what you get?

Non sequential transfers can drop to 1/10th that of sequential transfers
depending on the seek performance and latency of a drive.
30MB/s on a 2940UW for nonsequential transfers is very good if not exceptional.
The faster the seeks and lower the latency the better the nonsequential per-
formance. Yet 30MB/s for pure sequential is still not that bad either.
Depends on how much and how long you can setup sequential tranfers without
interruption. Pure sequencial is likely not even achievable anyway, except for maybe
cloning one harddrive to another.
Pick a 15k cheetah for trial.

When I was running an XP2200 CPU I did that upgrade. It is better than |
IDE on that generation of motherboard. As you already have the hardware, go
for it. HDTACH shows a definate difference. The IDE controller also uses the
PCI bus, so there will be no change in that.

Probably not.
The IDE controller in recent CPU chipsets usually connects directly into the
north and south bridge bus.

Only if it's connected to a/the PCI bus.

when i upgraded my p4 2.4mhx to a 10k SCSI drive about 3 years ago
the performance almost doubled
& since this will cost you nothing it's a great idea
