Advise on Drive combination for RocketRaid 640

[Aussie Allan]

   Nice to be able to use my favourite resource again!

  Well I'm waiting on my RMA Highpoint RocketRaid 640 PCI-E card and have decided to finish the total upgrade early.....

 The 4x SATA II SamSung Spinpoints (501LJ) are to be retired and some new SATA III drives are going in, ... or maybe only two, as I been told this card flies with one drive on each controller (9128 chip) but can take two per controller, although the same performance gain is not realized going from 2 to 4 drives...... So here's the list I need to get answers too.

 1) What speeds can I expect going from SATA II to SATA III in Raid 0 on this card.... mid spec drives ,...say 7200, 16meg cache, 2TB

 2) 2 drives or 4

 3) Alternative ideas welcome .

Mechanical hard drives will not be any quicker on the sata 3 interface as they cannot even saturate sata 2. I get decent performance from my 2TB drives, whilst they haven't got the same access times they offer the same transfer rate as my old raptors.

I would think you will get a small boost in performance with 4 drives in raid 0, but then you have more data to lose. Do you need 8TB of space? You could always buy 2 drives for now and then buy 2 more in future, they can only get cheaper.

  Yeh! I agree to a point........one of the reason I went with the card in the first place was it will give me what my board won't ... and that's the 6Gb/s for connectivity .

 Funnily enough were the onboard 88SE9128 chip never delivered, the same chip (X2) in this card apparently does!.......this is only to be used as mass photo storage.........I filled 1.8TB with not to much trouble as most of my work is with HDR bracketed images, ... so one of your photo's/images =5,7 or 9 for me........ shooting 14 and 24MP in RAW..see where I'm coming from........to be more specific on one point then, ... one spinpoint would give me about 85Mb/s on a short stroke......6 in raid 0 got me about 420Mb/s..........what can I expect from some late spec drives running SATA III

 I say storage as I have a RevoDrive x 2 for boot and am more then happy, but need a quickish drive set for storage and Programs.

*
With one disk HDTune 80 Mo/s

Two disks 160 Mo/s ...

finally some x disks * 80 Mo/s

I have tested  6 * disks with my Motherboards  ( port Intel , ASUS or GigaByte same results ) in Raid 0 --> some 500 Mo/s but only for test !!

A long time i use 4 disks in RAID 0 + 1

Speed is exactly the same as my Addonics box in RAID 10 --> 160Mo/s

* Raid 0 is absolutly not secure requiert UPS and not savage power down !!

[Aussie Allan]

 Thanks pierre!

 Now where getting somewhere, ... so these figures are for SATA II drives you are quoting ? 80Mo/s (French)  80Mb/s (English) is this correct ?

 So with SATA III we can get max 500Mo/s...?

 And with SATA II max 400-425Mo/s....?

 Do you have Mo/s for SATA III drive, single drive ?

  I have 2000watt UPS

 I have backup running 24/7 every 2 hours + clone update copy write every 2 hours.... all on auto

 And thank you again Pierre......Merci Buku

Test with my disks

1 - single disk connected to the INTEL port

***

For the others i use my extarnal 2 * Addonics HPM AD4SR5HPMU with 4 * disks in RAID 10

HDtune condition : fast , BenchMark 8MB

For my RR622 i have at this time not the HighPoint firmware / drivers but the MaxPower version
