Momentus XT, Momentus, Momentus Thin, MobileMax, and other notebook drives

I'd really appreciate it if Seagate would answer this....

I might have to press an old Momentus XT V1 drive into NAS operation to demonstrate a product for someoe....

I need high speed transfer, so the drive will be formatted as XFS to gain the high speed transfer speeds... This will be mounted via an Esata interface instead of USB for higher speed transfers, too...

My question in..... How will the Momentus XT SSD Cache fare with the XFS format, comparted to NTFS???

Obviously, if the XT V1 drive is fine, same question on the XT V2 drive.... as it should be faster with it's faster buss and larger SSD Cache.

If all is well, fine... If it's not good, I'd like to know about it prior to my building the prototype test unit....

Thanks for a speedy reply....

Aparantly this  NAS only supports SATA 1 speeds (1.5Gb/sec)....

Still interested in how  good SSD Cache will work with XFS formatting, though!

Anyone?

This is EMBARRASSING!!!!

So I went to Seagate site and asked the same question as above.....

I had to escalate the support email.....

This is the answer I received!!!! 

Thank you for contacting Seagate Support. I will be happy to assist you. The momentus XT will benefit with the larger cache and a higher transfer rate. You will also get faster loading times for boot up and application use. I hope this helps.

Can NO ONE AT SEAGATE READ??????

I would have thought that by now SOMEONE at Seagate would have posted  about this....

I really would like to hear about this.... It's really amazing that a company who makes hard drives would not have tried every format known to man to see how it would work........

<<wince>>

Yes, someone at Seagate can read. 

Please accept my apologies. I will make sure that this is investigated.

Thanks for bringing this to my attention.

Thank you, Alan.... I'm interested because a good friend just upgraded from XT1 drive to SSD in a Mac laptop.... and he's giving the XT1 drive to me.......  and my intent is to try it in the mentioned NAS under XFS format to gain the higher drive bandwidth....

The NAS claims XFS will do nearly 3x the speed of NTFS.

Thank you for looking into this...

Disappointing results so far.

Per the manual I should be getting 60MB/sec Writes, 80MB/sec Reads with the drive in an ESATA enclosure, MBR setting, and XFS format.... (Compared to NTFS/USB's 5MB/sec Write 16MB/sec Read)..

Darn! I'm only getting 17MB/sec Reads from the Momentus XTV1 Drive (SD28) set as MBR and XFS format in an ESATA Enclosure...

[JanJanowski]

I did open up a ticket with the NAS Manufacturer.....

I'll post what they say.....

[JanJanowski]

There is a possibility that the XFS format didn't 'take'. I'll know more tonight.... I'd much rather have it be a operational error on my part than a bug...

More later tonight....

[JanJanowski]

The drive is XFS....

I tried a wired connection and wireless...

From a wired Server with 1Gb Ethernet, through GB Switch, to NAS I get 27Mb Reads.... Should be 85Mb max Reads...

Ok Seagate... What did you come up with?
