Re: Extreme Performance with 10 Years Warranty - SanDisk Extreme PRO Review

64K - Write - Average 443.9 MB/s Access Time 0.026ms
8MB - Write - Average 490.1 MB/s Access Time 0.036ms


64K - Write - Average 429.7 MB/s Access Time 0.027ms
8MB - Write - Average 486.9 MB/s Access Time 0.038ms


SanDisk Extreme PRO is excellent in HD Tune Pro Write.
The seeking time is around 0.026~0.038ms. The key is writing curve starting above 400 MB/s.
I used to test some high end SSD. The 64K Writetransmission speed is significant upand down, or average speed below 200 MB/s.
SanDisk Extreme PRO is close to 430 MB/s during test.

File Benchmark
Sequential 4KB randon Read - 97383 IOPS / Write - 86810 IOPS
ATTO DISK Benchmark over 128KB starts to reach max Read 560.5 Mb/s and Write 526.3 MB/s


Sequential 4KB randon Read - 97403 IOPS / Write - 85818 IOPS
ATTO DISK Benchmark over 64KB starts to reach max Read523.7 Mb/sand Write 526.3 MB/s


ATTO DISK Benchmark over 64K starts to reach max Read /Write 500 MB/s.
The 0.5~2K data transfer rate is even better. It leads Intel 730 Series 480GB a lot.

CrystalDiskMark
Seq Read - 547.8 MB/s Write - 514.3 MB/s
<All 0xFF, 0Fill> Read - 550.9 MB/s Write - 516.8 MB/s
<All 0x00, 1Fill> Read - 548.0 MB/s Write - 514.3 MB/s


Seq Read - 548.3 MB/s Write - 515.4 MB/s
<All 0xFF, 0Fill> Read - 548.0 MB/s Write - 514.9MB/s
<All 0x00, 1Fill> Read - 548.8 MB/s Write - 515.2 MB/s


CrystalDiskMark random test and 2 sequential mode speed are the same.
This is one of the main advantage of Marvell Controller. Seq performance is close to official specs.
4K QD32 Write and Read are top level of current SATA3 SSD.

AS SSD Benchmark - 1118
Seq Read - 526.51 MB/s Write - 494.30 MB/s
4K - 64Thrd Read - 357.62 MB/s Write - 247.29 MB/s


AS SSD Benchmark - 1175
Seq Read - 525.94 MB/s Write - 492.08 MB/s
4K - 64Thrd Read - 367.33 MB/s Write - 292.44 MB/s



Current top level SATA3 SSD can reach more than 1100 in AS SSD Benchmark.
4K-64Thrd Read can reach 357~367MB/s. This is new key factor for SSD performance.
Compression Benchmark is also consisntent.
Seq Read is 525MB/s and Seq Write is 494MB/s.

PCMark Vantage - HDD Score : 78950
SSD Benchmark TOTAL => 5127.39


PCMark Vantage - HDD Score : 78162
SSD Benchmark TOTAL => 5093.71


Its a pity that PCMark Vantage HDD doesnt reach 81000, which official claim.
The performance gap is around 2.6~3.5%. Its still acceptable. I also upgrade G1.Sniper Z97 BIOS to F6.
F6 is marked improving SSD performance. In the past, GIGABYTE MBSSD performance is lower.
It might be MB tuning issue. I hope GIGABYTE can enhance BIOS to complete the SSD performance.

Iometer
5 minutes - 100% Write / 100% Random 4KB
Total I/Os per Second => 86380.81


5minutes - 100% Write / 100% Random 4KB
Total I/Os per Second => 86356.60


5minutes - 100% Read / 100% Random 4KB
Total I/Os per Second => 96403.27


5minutes - 100% Read / 100% Random 4KB
Total I/Os per Second => 97599.02


You can see the Random Read / Write 4KB in IOMETER 2008 are really high.
The key is after 20 mins repeating test, there is no decline as SanForce controller.
Marvell 88SS9187 controller performance wont decline. Its standard technology for current high end SSD.

Comparing to former Extreme II, Extreme PRO performance doesnt improve much.
However, using same Marvell Controller and own latest NAND Flash, official specs show power consumption is 30% lower.
In such low power consumption, the Extreme PRO performance is really outstanding.

Second part is NoteBook test. I use DELL New!Alienware 17.
As high end Gaming Notebook in the market, the performance and hardward specs are all top level.


AlienFX lighting is DELL New!Alienware body surrounding many LEDs.
The shell is coating aluminumand soft touch rubberized finish. Its magnesium-alloy frame for better quality, texture and durability.
Its 17.3 antiglare FHD monitor. The speaker is the best I have ever used in Notebook.
It supports one mSATA and two 2.5 SATA3. I change to Sandisk Extreme PRO SSD.


Sandisk Extreme PRO 480GB SSD install at SATA3 port as system drive.
OS installs Windows7 Ultimate 64bit, all drivers and Intel Smart Response Technology.
AS SSD Benchmark - 1095
Seq Read - 512.79 MB/s Write - 485.38 MB/s
4K - 64Thrd Read - 362.11 MB/s Write - 283.22 MB/s


ATTO DISK Benchmark over 128KB can reach max Read 560.5 Mb/s and Write 526.3 MB/s
CrystalDiskMark
Seq Read - 547.8 MB/s Write - 512.5 MB/s


Comparing to Desktop PC numbers, most benchmark in Notebook is similar.
It means even Sandisk Extreme PRO SSD set as system drive, the performance is still good.
Of course, DELL New!Alienware SATA3 optimization is high, also enhance Extreme PRO scores.

BootRacer
Boot Result => 14.142 seconds


In BootRacer, it needs only 14.142 seconds. The speed is really fast.
Of course, if you only install drivers without any software, the booting time will be less than 12 seconds.
However, I think this kind of test is no reference value. Complete installation is more close to reality using environment.
If I change to Windows 8.1, the booting time will be faster. But its not popular yet.
After consideration, I still use Windows 7 as OS.

Recently many Z97 MB supports M.2(N.G.F.F.) spec up to 1000MB/s bandwidth.
Some high end M.2 SSD can reach more than 700 MB/s bandwidth. Most is 500MB/s.
Also, MB only support one M.2 SSD, the price and RAID application still far away to be mainstream.
SATA is main specs for years. If you want to upgrade your system performance, SATA3 SSD is first choice.
Now, SSD is also divided into parity and high performance.



SanDisk Extreme PRO strength in SSD market is Random4K Read/Write can reach 100K/90K IOPS.
SequentialRead/Write can be up to 550/515~520 MB/s. Its almost the best SSD specs in the market now.
SanDisk performance tuning is outstanding to make 240/480/960GB have same performance.
Extreme PRO provides 10 years conditional warranty. Its also the longest in the market.
After service cost is high, of course it impacts the product price segment.
As cost/performance, SAMSUNG 840PRO should be the opposing force, next is Intel 730 Series.
If you want to pick high end SATA3 SSD, for max performance and warranty, Extreme PRO is a good option.
Its windwithme review test about SanDisk latest Extreme PRO SSD. :)

It will also post in my blog WIND3C, Any comments are welcome.
