Testing Setup
To get a good idea of SSD performance, both out of the box and down the line following extended use, we've adapted our TRIM testing methods from previous SSD reviews. Drives are tested in both a 'clean' new state having been reset to factory performance by
HDDerase.
To simulate a protracted heavy workload we then connected the drives to a secondary system running
without TRIM support and copied the entire 100GB contents of the c: drive over to the SSD. These files include operating system files, multiple game installs, MP3s and larger video files – the typical contents of a modern hard disk. Once the write to the SSD was completed these files were then deleted and the process repeated ten times, resulting in a total write of over 500GB to our SSDs.
We then move the SSD back to the test system (filled from their last write), and clear the drive with a standard windows delete command, followed by an emptying of the recycle bin to ensure the TRIM command had been triggered. The drive is then left for an hour to ensure the TRIM command and any garbage collection algorithms had been completed before being retested using our new suite of benchmarks.
Common Components
- Intel Core i7-920 (operating at 2.66GHz – 20x133MHz) - TurboBoost and power saving states disabled.
- Gigabyte X58A-UD7 motherboard (Intel X58 with ICH10R Southbridge, USB 3 and Marvell SATA 6Gbps)
- 3x 2GB Corsair XMS3 1,333MHz DDR3 memory
- Nvidia GeForce GT 240 512MB
- PC Power & Cooling Silencer 750W PSU
- Windows 7 Home Premium x86-64
- Nvidia Forceware 196.21 WHQL
- Stock Windows AHCI driver (msahci.sys)
TRIM is confirmed as running by using the command line and entering
fsutil behavior query disabledeletenotify - a response of disabledeletenotify = 0 indicates TRIM is active.

Are these SSDs faster than that old Gigabyte RAMdisk?

IIRC, reviews put it somewhere around 100MB/sec, which is much slower than SSDs. Remember, that was 'ancient' PC-3200 DDR memory. Hey, that might even be in F3 territory.
Now I feel like an old fart for remembering how excited everyone was when we moved from PC-2400 to PC-2700 and then PC-3200. And the big move from 100mhz to 133mhz FSB. Now my RAM is like PC3-12800 or something silly like that.
Edit - Checked another benchmark site. Surprised me. RAMdisk is still significantly faster than anything mechanical, and on par with some older SSDs.

Silly Question #2 - Firmware upgrades, not sure if this is still that case, but the 1st Gen SSDs required that any RAID setup be unmapped for individual drive firmware upgades. How is that handled by this integrated solution? When I got my first SSD (1st Gen Vertex 120GB), firmware upgrades were a weekly release!
