It supports 3 PCI-E X16, 3 PCI-E X1 and 1 PCI. In design, components and upgradability are all good.
Intel chipset always has better IO transfer rate. Also, 7 series chipset officially supports Raid 0 Trim.

Single CORSAIR Neutron GTX 240GB installed on SATA3.
It's Non-OS system drive without data.
Test performance on Intel Z77 platform.
HD Tune Pro 5.00
Black Size is a special feature. Left side is default 64K and right is 8MB.
64K - Read - Average 448.0 MB/s Access Time 0.028ms
8MB - Read - Average 521.7 MB/s Access Time 0.029ms
64K - Write - Average 173.5 MB/s Access Time 0.024ms
8MB - Write - Average 389.5 MB/s Access Time 0.026ms
In 64K Write, it's not stable. However, some parts have good performance.
Especially, Access Time is less than 0.030ms. It's really helpful for shorten waiting time.
Sequential 4KB randon Read - 93132 IOPS / Write - 84069 IOPS
ATTO DISK Benchmark over 128KB, the max read is 550.3 Mb/s and write is 465.1 MB/s.
In Random 4K test, the max read performance is 90 IOPS and max write is 85 IOPS.
You can see the performance is almost same as official specs.
Seq Read - 533.6 MB/s Write - 457.5 MB/s
Read - 533.7 MB/s Write - 458.7 MB/s
Read - 533.7 MB/s Write - 457.8 MB/s
CrystalDiskMark default test in random and sequential are the same performance.
This part is similar to Marvell Controller. it's one of LM87800 Controller advantages.
By the way, Write Seq and 4K QD32 are higher than Marvell Controller.
AS SSD Benchmark - 1136
Seq Read - 516.87 MB/s Write - 440.97 MB/s
4K - 64Thrd Read - 363.93 MB/s Write - 302.26 MB/s
AS SSD Benchmark total score is 1136. For most SATA3 SSD, this score is really high.
4K-64Thrd breakthrough 300MB/s is another index for new high performance SSD.
Compression Benchmark is consistent straight line.
Read is above 510MB/s and write is about 429MB/s.
PCMark Vantage - HDD Score : 75785
SSD Benchmark TOTAL => 4577.92
5 minutes - 100% Read / 100% Random 4KB
Total I/Os per Second => 94687.41
5 minutes - 100% Write / 100% Random 4KB
Total I/Os per Second => 84414.03
As you can see IOMETER 2008 Random Read / Write 4KB benchmark is very good.
The important thing is running after 30 minutes, it doesn?t decline as SandForce.
Neutron GTX uses LM87800 Controller should be same as Marvell flaunting non-declining technology.
