SATA III speeds running at SATA II Not full speed help...

[Scooter_2478]

Hello,

    I had purchased 2x HP M/N:MB2000EBZQC (Seagate Constellation ES M/N:ST2000NM0011) and they are supposed to be SATA 3 6GB/s transfer rate drives by Seagate but the drives are only running at SATA 2 3GB/s. Does anyone know what speed the drives are supposed to be? According to a Seagate tech, the HP drives are OEM and have custom firmware. Did HP install firmware to "dumb down" the transfer rate of the drives from SATA 3 to SATA 2? I so, WHY would the do this?

@Scooter_2478,

SATA speeds are based on factors, 1) Complete chipset and 2) hard drive specs.  Drives will default to the SATA speed of the host computer. Download this program.

Indeed: where do you connect them to?

@krzemien,

Do you havre a point?

I was chanllenging the OP to mention the computer model .

[krzemien]

I'm curious what OP connects these disks to, i.e. PC model and its chipsets etc.

Is this point good enough for you so I can keep responding / commenting / contributing?

@krzemien,

Your point is well taken, as explained now. Keep on tasking these OP's.

The OP is playing a part number game !!   We got spoofed.

The MB2000EBZQC is Sata 300 as shown here    and here

The Seagate ST2000NM001 is SATA 600 as shown here

I had posted on this forum for the hardware which is "HP" SATA hard drives made by Seagate.

My system is custom built. Heres the specifications:

PSU: 1000W

Motherboard: MSI Z170A Gaming M5

CPU: Intel core i5 7600k

GPU: MSI Radeon RX 580 8GB Armor MK2

RAM: 2x 8GB G.Skill DDR4 @ 3000mhz

M.2: 256GB Western Digital Black WDC WDS256G1X0C @ 4000+ R/W

HDD: 2x HP M/N:MB2000EBZQC Seagate Constellation ES M/N:ST2000NM0011 (same drive)

DVD: SATA HL-DT-ST DVDRAM GH15F

OK, so assuming that disks are SATA III and they should work as such. Where do you see them exactly connected / recognised as SATA II?

Also, there's no jumper there that limits the speed, is there?

My quick research seems indicating that it might be a duff firmware installed on the drives.

When I first installed the drives I had done a DiskMark benchmark on the drives in RAID0 and the score was above 400+mbps. When I had first noticed the speed change I checked Intel Rapid Storage Technology app and it showed Transfer Rate 3Gb/s (SATA II). After that I ran another benchmark and the score was arround 200+mbps. I recently looked at CrystalDiskInfo which shows Transfer Rate SATA/300|SATA/300 and HWINFO shows Serial ATA 3Gb/s @ 3Gb/s. the model numbers show as the HP MB2000EBZQC (Firmware HPG2) but the Serial Numbers are Seagate Z1P30D81 & Z1P33DNA using CrystalDiskInfo & HWINFO. The drive has pins but no jumpers and its pins look like the audio connector on optical drives.

heres one of the Hard Drives.

Get one of these chappies:

http://www.hdtune.com/

And check what they report under Tools / DriveID or Info tab.

I assume you have the latest RST driver installed?
