I'm looking for ways to hook up fast 6 Gb/s SATA SSD's (non-RAID!) to (server or i-X58) mainboards which do not have native 6 Gb/s SATA. From the reviews I've read so far, two things became obvious: * The SSD's I'm looking at really want a working SATA TRIM command. * All the onboard Marvell 88SE9128 (or ASmedia) solutions seriuosly lack performance, as do PCIe cards based on those chips. So basically, there seem to be two choices: 1.) LSI 2008 2.) Marvell 9485 1.) seems to be fast, reliable and well-supported, but as far as I can tell, it doesn't support TRIM at all: It neither maps SCSI unmap to SATA TRIM, nor accepts TRIM as a SATA passthrough command. Is that true? I didn't find much about 2.) * The only cards based on this chip are the HighPoint 27xx, or did I miss something? * Running a 27xx with the mvsas driver was reported to have stability problems or random errors. Are these problems solved? * Is the 27xx fast (with SATA SSD's & mvsas driver), i.e. significantly faster than onboard SATA 3 Gb/s ports? * Does the 27xx+mvsas support TRIM when connected to SATA drives? Are there any other solutions? -- Prof. Dr. Klaus Kusche Private address: Rainstraße 9/1, 88316 Isny, Germany +49 7562 6211377 Klaus.Kusche@xxxxxxxxxxxxxxx http://www.computerix.info Office address: NTA Isny gGmbH, Seidenstraße 12-35, 88316 Isny, Germany +49 7562 9707 36 kusche@xxxxxxxxxxx http://www.nta-isny.de -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
