Savvio, Cheetah, and Constellation Enterprise Server & Storage (SCSI/FC/SAS/SATA) drives

[esuade]

Hello
I look for help in this official Seagate forum for issue with my two ST3600057SS in RAID 0 with LSI 1068E on Supermicro X8DA3.
The write performaces of this array (D) are tragic.
I also have in the same system two ST3450857SS in RAID 0 (E) with no write performace issue.

Firmware is the same for all drives: 0006, settings are the same, controller setup is the same.

I don't know where the problem can be.

Thank's a lot and sorry for my english

Marco

Have you tried a Queue Depth of 1?

FWIW, here is a HP firmware update:

I'd be very wary about applying a HP update to a retail drive, though. You would need to satisfy yourself whether it is OK to do so.

Hello fzabkar thanks for reply
I'm not sure a firmware update is not suitable to drive, but
I do not think the firmware issue, because even the two ST3450857SS have the same firmware and work fine.
As soon as, after backup, I delete raid and test single drive for write speed.

Thanks’

esuade, Have you found a solution to this?


I think I have the same issue with my Seagate Cheetah 15K.7 ST3600057SS, good read performance but poor write performance after a few seconds of writing. I have tried my ST3600057SS with a RocketRAID 2640x4, LSI SAS 9211-4I and an Adaptec RAID 2405, all with the latest firmwares, and all have the same issue. I have sent my Seagate drive back to the store and they will test it, maybe it is a broken unit like yours.


Specs:

Windows 7 64bit
Windows 8 64bit RTM (msdn lisence)
Asus P9X79 Deluxe chipset drivers 9.3.0.1019
i7 3930K
16gb ram
Seagate Cheetah 15K.7 SAS ST3600057SS firmware 0008
WD Velociraptor 600GB SATA
WD Raptor 150GB SATA
RocketRaid 2640x4 drivers 1.6-12.524 firmware 1.4
LSI SAS 9211-4I
Adaptec RAID 2405
Single drive setup as JBOD

I got a new drive, and it has the same problem. I tested it in a different computer this time, and it was now detected by Seatools. I ran three tests, and they all passed.

Short Drive Self Test (Short DST) - pass

Generic short - Pass

Generic Long - Pass

I''ve tested different write and read cache settings in both Windows and Adaptec Raid manager but no change. I'll test some MBR and GPT but probably exchange the drive again, this time for a Hitachi Ultrastar 15K600.

Specs this time:

Windows 7 64bit

Gigabyte GA-965P-DS4

Adaptec Raid 2405

Seagate Cheetah ST3600057SS

hmm this forum has issues with Opera browser.

Success! 

I switched for a Hitachi 15K600 Ultrastar 0B23663 HUS156060VLS600 and write performance is fine, both in Windows 7 and Windows 8.

I have been in contact with Seagate tech support and here is what they said:

- I apologize for any inconvenience this may have caused you. Unfortunately we do not have any tools that test the sequential write performance. Normally if there are issues with the drive , Seatools would fail the tests or give you an error code.

This means that Seagate does not have any way of testing performance, and you are stuck with a problematic drive. Due to this, I won't be buying Seagate products for a while. I was lucky that my retailer where I bought the drive accepted my returns and let me change to a Hitachi drive.

Hey DarkUltra, your pics seem to be broken.
