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. System Configuration CPU: Intel Core i5-3570K MB: GIGABYTE Z77X-UP5 TH DRAM: CORSAIR Dominator Platinum CMD16GX3M4A2400C9 VGA: Intel HD Graphics 4000 HD: CORSAIR Neutron GTX 240GB / TOSHIBA 5400rpm 500GB POWER: XIGMATEK Tauro 400W Bronze Cooler: XIGMATEK HDT-S1283 OS: Windows7 Ultimate 64bit 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. File Benchmark 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. CrystalDiskMark Seq Read - 533.6 MB/s Write - 457.5 MB/s <All 0xFF, 0Fill> Read - 533.7 MB/s Write - 458.7 MB/s <All 0x00, 1Fill> 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. |
Neutron GTX 240GB Installs Windows7 Ultimate 64bit for booting time test All drivers except LAN and Intel Smart Response Technology installed. BootRacer Time to Logon 3~4 seconds Time to Desktop 9.373~10.436 seconds Install LAN driver and plug in LAN cable Time to Logon 4~5 seconds Time to Desktop 9.202~11.964 seconds Basically, after entering desktop, LAN will search for a while, so you can see the booting time is 1~2 seconds longer. Neutron GTX booting speed is excellent. It takes less than 12 seconds with all drivers installed. Of course, the booting speed will be slower due to users installed TSR. This is just for your reference. 2nd part is using tow 240GB with Raid 0 mode Two CORSAIR Neutron GTX 240GB install 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 1044.0 MB/s Access Time 0.035ms 8MB - Read - Average 1047.6 MB/s Access Time 0.034ms 64K - Write - Average 888.5 MB/s Access Time 0.013ms 8MB - Write - Average 886.9 MB/s Access Time 0.013ms In Raid 0 mode, no matter Black Size set at 64K or 8MB, all can get very high speed. The speed is almost double the single SSD performance. File Benchmark Sequential 4KB randon Read - 110266 IOPS / Write - 129829 IOPS ATTO DISK Benchmark over 8KB test can reach max read 1109 Mb/s and write 930.2 MB/s. Sequential 4KB randon Read increases 18% and 4KB random Write increases 54%. ATTO DISK Benchmark in 8KB is almost reaching the highest performance already. If you are using more small size files, you still can experience Neutron GTX high speed. CrystalDiskMark Seq Read - 1019 MB/s Write - 900.5 MB/s <All 0xFF, 0Fill> Read - 1036 MB/s Write - 901.2 MB/s <All 0x00, 1Fill> Read - 1006 MB/s Write - 900.6MB/s CrystalDiskMark benchmark is almost same as HD Tune Pro. It's close to double performance. AS SSD Benchmark - 1897 Seq Read - 994.13 MB/s Write - 900.63 MB/s 4K - 64Thrd Read - 553.72 MB/s Write - 508.71 MB/s AS SSD Benchmark total score increases around 67%. Seq Write performance is even 2 times more than single SSD. PCMark Vantage - HDD Score : 96420 SSD Benchmark TOTAL => 7779.48 PCMark Vantage - HDD Score increases 67%. SSD Benchmark TOTAL is 70% more. Neutron GTX 240GB Raio 0 installed Windows7 Ultimate 64bit to test booting time. All drivers except LAN and Intel Smart Response Technology installed. BootRacer Time to Logon 3~4 seconds Time to Desktop 9.248~10.216 seconds Raid 0 booting speed is almost the same. However, 9.2~10.2 is the fastest speed I have ever seen. Former several SSD still took 11~14 seconds. |
CORSAIR Neutron GTX Raid 0 mode performance is excellent. Most benchmark is almost double the performance. Most software has 70% improved, also write curve is very stable. Intel Rapid Storage Technology starts to support Raid 0 Trim in 7 series chipset. For the enthusiasts or requiring high speed transfer, this is a good news. Also make SSD be used in more environment. CORSAIR Neutron Series extends warranty to 5 years and uses latest LM87800 Controller. Neutron uses ONFI NAND Flash which is lower price and full 256GB capacity. Neutron GTX uses Toggle NAND Flash which is higher performance with 16GB buffer. This is the difference in two Neutron 256GB models. SATA3 SSD read performance has reached 500 MB/s since long time ago. Recently, SSD design is more on writing performance to reach 400~500 MB/s or 4K performance to 300 MB/s. Another goal is non-declining at 85~95K Random 4K IOPS after using for long time. You can see SATA3 SSD trying hard to utilize 6Gb/s bandwidth. The performance is getting higher and higher. CORSAIR Neutron GTX is most benchmark are one of the best in SSD market. The price is slight higher. With new controller, it brings another options to users in high end SSD market. :) This article is also post in my blog - WIND3C, Any comments are welcome. |
