runnerhurricane3 Posted January 31, 2012 Share Posted January 31, 2012 Hi all, I just bought this ssd and I'm getting low speeds. Even lower than my old Force 120. Is it my mb's fault or something else? I read on the forum that you should connect the ssd to the grey sata port, but in that case it goes even slower because Windows sees it as SCSI. What can I do? Thanks. Corsair Force GT 180GB: http://i41.tinypic.com/116hvo4.jpg Corsair Force 120GB: http://i43.tinypic.com/t8khmh.jpg Link to comment Share on other sites More sharing options...
FoLmEr Posted January 31, 2012 Share Posted January 31, 2012 The speeds you're getting are perfect SATA II speeds so your drive is fine. If you want higher speeds, you'll have to connect it to your mobo's SATA III connector, and even then, it'll be somewhat handicapped because of the Marvell chip controlling your mobo's SATA III connectors. The Marvell controller does support AHCI via a setting in the BIOS setup, so windows recognizing it only as SCSI should not be a concern. If you want the full speed of SATA III you'll need a mobo with either native Intel or AMD SATA III connectors (p67, z68, x79 and newer chipsets).

runnerhurricane3 Posted January 31, 2012 Author Share Posted January 31, 2012 Hi, thanks for your answer. I didn't get exactly the part about the SATA III port and why my computer sees it as SCSI and how to set it good. By the way, why do I have better performance on the Force than on GT?

FoLmEr Posted January 31, 2012 Share Posted January 31, 2012 Oh okay, well in the BIOS setup on your motherboard you can change the mode of the Marvell controller to AHCI, thereby enabling more advanced storage performance (and making it NOT appear like a SCSI device). Don't ask me about the specifics of where the setting is located, you'll have to consult your mobo manual about that one. And you don't really have "better" performance from the Force, since all the ATTO results show is a fully saturated SATA II connection. The marginal and insignificant differences in the results are due to things like concurrent disk access, antivirus scanner activity, windows update, indexing, level of the used state of the SSDs etc. Bottom line: Nothing to worry about. I do understand if you want the unlock the full performance of your ForceGT but for that you'll need to invest in a newer motherboard with better SATA III support, as already stated. Only then will you see the rated speeds of 500+ MB/s in the ATTO benchmark. Link to comment Share on other sites More sharing options...
Toasted Posted February 1, 2012 Share Posted February 1, 2012 You plugged it in to the Jmircon port, Try plugging it into the Intel SATA Ports (Right-angled ports). From the ASUS product page Intel® P55 Express Chipset built-in 6 xSATA 3.0 Gb/s ports Intel Matrix Storage Technology Support RAID 0,1,5,10 JMicron® JMB363 PATA and SATA controller 1 xUltraDMA 133/100/66 for up to 2 PATA devices 1 xSATA 3Gb/s port (black) JMicron® JMB322 (Drive Xpert Technology) : - 2 x SATA 3.0 Gb/s ports (navy blue and gray) - Supports EZ Backup and SuperSpeed functions *Drive Xpert function is available only when the hard disk drives are set as data drives.

runnerhurricane3 Posted February 1, 2012 Author Share Posted February 1, 2012 I connected it to the black port but as I said, in windows it shows as SCSI Disk Device. In the BIOS is set AHCI. Link to comment Share on other sites More sharing options...
runnerhurricane3 Posted February 1, 2012 Author Share Posted February 1, 2012 Another information: in BIOS, when connected to the blue, grey or black SATA port, it shows it as IDE and also the software Intel Rapid doesn't show the GT. Link to comment Share on other sites More sharing options...
Toasted Posted February 2, 2012 Share Posted February 2, 2012 What do you mean it shows as IDE and Intel Rapid does not detect it? Link to comment Share on other sites More sharing options...
runnerhurricane3 Posted February 2, 2012 Author Share Posted February 2, 2012 In the boot drive settings in the BIOS before the name of the SSD is shown "IDE:" when the SSD is connected to the blue, gray or black SATA port. Also the software Intel Rapid doesn't show in the list the SSD. What I think is that the black,blue and grey ports are JMicron. Link to comment Share on other sites More sharing options...
runnerhurricane3 Posted February 2, 2012 Author Share Posted February 2, 2012 I just did a try with an ASUS U3S6 PCIe with 2 SATA III and 2 USB 3.0. Of course it has a Marvell controller so write speed is capped... I was wondering if there are other PCIe boards with better performance controllers. Anyone know one?

FoLmEr Posted February 3, 2012 Share Posted February 3, 2012 I believe the general consensus is that PCIe SATA3 controller cards are either: Too expensive - they're designed for business and you could buy a new PC for the price (with proper SATA3 support, I might add) Not worth it - they're based on a Marvell controller (likely the one your mobo has) and it's not an upgrade at all.

Turbonerfs101e Posted February 3, 2012 Share Posted February 3, 2012 Hi Ther is the highpiont 2720sgl controller for lest then 200$ It could andle up to 8 drive at a maximum speed ove 2800mb/s i get 1000mb/s with 2 ssd and planig to buy 2 more. hope this help you. sincerly yours.

Toasted Posted February 4, 2012 Share Posted February 4, 2012 Intel RST will not detect the SSD since it isn't plugged into the Intel SATA port. Have you tried the light blue ports? Link to comment Share on other sites More sharing options...
runnerhurricane3 Posted February 5, 2012 Author Share Posted February 5, 2012 Yes but then speed is slower because they're sata 2 Link to comment Share on other sites More sharing options...
Toasted Posted February 6, 2012 Share Posted February 6, 2012 SATA 2 = SATA 3GB/s SATA 3 = SATA 6GB/s Link to comment Share on other sites More sharing options...
FoLmEr Posted February 6, 2012 Share Posted February 6, 2012 Just to nitpick further, it's actually Gb/s since there's a difference between bits (b) and bytes (B) Link to comment Share on other sites More sharing options...
runnerhurricane3 Posted February 9, 2012 Author Share Posted February 9, 2012 Then explain me why on SATA II it doesn't go more than 200 :P Link to comment Share on other sites More sharing options...
Turbonerfs101e Posted February 9, 2012 Share Posted February 9, 2012 Hi all. your board dont ave sata3 controller only sata2 Sata2 maximum speed is around 280mb/s, so you will not get more out ove it. U ave tu use sata3 controller to get full speed. U can get thos speed with a pcie 8x controlleur. Like the highpoint 2720sgl For about 200$ u could hook up to 8 drive in raid to get the maximum ove this card that is around 2800mb\s Hope this help Sincerly yours Link to comment Share on other sites More sharing options...
