Power Consumption

Thanks to the newer SF-2281 silicon, idle power consumption is down by ~36%. That's a welcome improvement since it puts the SSD 530 nearly on-par with Samsung's offerings. Power consumption under load has not changed, though. Unfortunately I can't test idle power consumption with HIPM+DIPM enabled to get the real idle power consumption in a laptop since it requires a laptop for testing (the registry change does not work with desktop chipsets). 

Drive Power Consumption - Idle

Drive Power Consumption - Sequential Write

    I count seven asus motherboards with mPCIE, not one, at newegg. Regarding 6bps sata saturated, just run with RAID 0, is that hard to figure out how to do?

    I don't think TRIM commands can be passed through to SSDs running in RAID 0. At one point the Intel storage drivers supported this, but I heard that this had been pulled. I can't find any documentation on this.

    Additionally, even though SSDs are fairly reliable, adding another drive simply adds another point for failure.

    You CAN pass TRIM commands through to SSDs running in Raid 0 on Intel hardware. It has NOT been pulled. You need to have the latest Intel Toolbox in combination with the latest RST drivers installed. I just TRIMMED both my arrays a couple days ago.

    Out of curiosity, is that an automated process, or does it require manual TRIM through the Intel SSD Toolbox? What RAID levels are supported?

    I also wonder about the compressibility of striped data and if there is any effect there.

    I pass TRIM to my RAID 0 Samsung 840 RAID through the Windows 8 defrag on my H87 chipset. Performance tests prove it works. Unfortunately if I have the IRST software installed the drives are downgraded to SATA 3Gbps. I tried different cables and everything. Uninstalling the IRST software after making the RAID 0 restores them to 6Gbps...

    It was my understanding that TRIM worked in RAID 0 with the newer RST drivers, but only on Intel 7 series chipsets and newer. I do like Intel products but this is one thing they shafted us on.

    I just TRIMMED both my arrays a few days ago and one array was on an Intel 6 series chipset. I know that series 6 was not previously supported but I was able to initiate TRIM on the array with the newest Intel Toolbox and the newest RST drivers for the first time the other day. I cannot confirm this is officially supported behavior but I was able to do it with the newest drivers. I would give it a try if you have a series 6 board.

    I don't really care about TRIM. Garbage Collection works better anyway, especially on SandForce drives.

    mPCIE is not the same as M.2

    I believe they are calling it "mPCIe Combo Card" which actually has two connects to one on the motherboard.
