接近$20000的玩具, 我立即把安裝了i7Extreme 975 CPU的Cooler Master Cosmos S電腦機箱拆開了，把原本的3Ware AMCC 9650SE-8LPML 8-Ports RAID Controller Card從底板的PCI-Express x16 slot拆掉，然後再從機箱拆去7隻並聯，行RAID0陣列的 Western Digital Raptor 10,000 rpm 傳統硬碟，機箱內的接線頓時變得簡潔起來。
為了測試這張Card的實力，小弟把另外一部安裝了許多不同類型的RAM Drives的i7Extreme 965 電腦和它作出比較。i7Extreme 965電腦安裝了一張Gigabyte i-RAM 4GB DDR1 RAM SATA-1 Card和 3Ware AMCC 9650SE-8LPML 8-Ports RAID Controller Card 並聯4隻ACARD 64GB DDR2 RAM Drives 行 8-Ports SATA-2 RAID5 陣列。
結論: PhotoFast G-Monster-Promise PCI-Express SSD (固態硬碟) 512GB Card，在HD Tune Pro File Benchmark，最高有超過1,000MB/s的讀取(read)和寫入(write)傳輸率
後加圖在 15版144#
大量有關ACARD的詳細測試在第18版, 175# 182#, 今次圖片又大又清

我成日唸, 究竟佢壞左有無得換既哩
如果有既話, 寫個program 用來釘死mbr 果堆cell 然後大量重覆不停頓既
read write 動作

如果係mlc, 可能不出十日舊野會打柴都未定,

唔知幾時至出現呢d flash killer既program 可以用來比user 做測試呢

另外, 如果寫一個block 有1000MB/s 我唔覺得出奇
但如果係用來做sql server 一必一必data 咁寫, 個flash 邊度有咁快頂得順bitwise 既r/w ?

另外, 對比既adata 根本就唔應該用raid5, raid5 去盡肯定唔會比四雙ram drive 走0 快
事關個latency 唔係響io 上面, 而係raid card 計算xnor 上面.
看番ram drive read/write 上既分別咁大就看得出...

My boss authorized me to act on his behalf to answer netfriends' questions:

The G-monstor card is HK$1980 for 512GB
My boss don't have IOPS programme.
My boss don't use PC to play games. He has Xbox 360 and PS/3 to play games.
i7 965 is stepping C0, i7 975 is stepping D0
Max o/c for i7 956 is 4GHz (stable)
Max o/c for i7 975 is 4.36GHz (stable)
G-Monstor card is very thick, it actually will obstruct three slots.
Therefore, it is only possible to install one display card (if it occupied two slots) and one G-Monstor card (since it occupied three slots)
My boss has tried to run ACARD DDR2 RAM Drives in RAID 0 mode, the transfer rates of both read and write are more or less the same as RAID5 mode. Therefore, he think that it may be due to the hardware limitation of the ACARD Drives instead of the transfer ability of RAID5.

In term of actual feeling, using ACARD Drives in RAID5 is more or less the same as using G-monstor card. But when comparing with one traditional Western Digital harddisk 7200rpm, the feeling is superfast, have over 10 times satisfaction!

My boss has BSc, MA, MCIArb, MRICS, MHKIS, MHKIE qualifications. He is a building professional and is working as a senior civil servant.

My boss told me G-monstor SSD card is faster than SSD SATA drive. It is not due to the SSD chips in G-monstor is more advanced than the others. It is actually due to using 4 layers of SSD in RAID0 mode and it is using PCI-Express x8 interface which is much more faster than SATA-2.

My boss don't play games in PC because he has xbox 360 and PS/3 to play games in large projector screen of 92inch with HD surround sound.
My boss expected that his PC will not perform very well in playing games since the G-monster card is too thick and obtructed three slots, therefore no chance to install more than one display card, cannot run SLI or Crossfire mode.

作者: 輕基黃    時間: 2009-6-16 15:17


My boss has already test the speed difference between RAID5 and RAID0 for the ACARD DDR-2 Drives, there is no difference in write and read transfer rates. He think that it may be due to the hardware limitation of ACARD instead of RAID. Bearing in mind that the speed of DDR-2 RAM should be the fastest. The poor performance should be on the ACARD.

My boss told me that one set PC is too dangerous. In order to cater for emergency breakdown of PC, he need one backup PC in case of hardware failure. Secondly, you can allocate different specific tasks to different PC. Say for example: for video & photo editing, the other for daily word processing, surfing the internet, it will reduce the chances of virus infections to the other PC.

請分清楚, 呢d 肯定唔係industrial grade 或者係millitary grade 既野
工/商用電腦從來唔講快, 重點係要極高穩定性同超長既mtbf

電腦有兩樣野要分得好清楚

1. 技術, 包括速度, 即technology
2. 等級, 包括品質, 即grade

好多時pc 家用級係講緊1. 因為呢個比較合消費環境
因為pc 用家要求有幾高, 當年pentium 計錯浮點, 如果呢堆cpu 響屋企用
一定唔會好似商用咁計錯數而分分鐘賠死人.......


但工商甚至軍用, 而家仲可能用緊p2~p3 添, 但係佢地講既grade
係一定要好嚴格, 買呢d 野都會有晒spec , 個mtbf 係幾多, error rate 係幾多, 做埋test 既.
甚至係會保用埋幾多萬個鐘或者係耐高溫耐電磁波等等, 要去到咁高grade, 一定要做好多error correction, 例如好多重型server 都用ecc 同埋registry ram, 呢d其實係拖慢ram 既,
但係加左佢地之後, error rate 可以減到近乎0, 所以好少錯誤,
拎普通ddr3 ram, 係好快呀, 但係如果好似計銀行帳因為ram 而計錯數, 咁就死得人多咯


右手邊果張咪係industrial grade 咯, 出面幾難搵架(仲有一張4g, 都仲要賣成千蚊張)
呢張咭係響一d 工業機器度拆出來既, 果d 機係長時間7x24 80c 環境用,
當年sandisk 128m 普通咭都係 slc (所以唔關slc 同mlc 分別, 真係grade 唔同既),
industrial grade 既card 比普通咭貴多不知幾多, 但唔係快

作者: 凌天羽    時間: 2009-6-17 03:28



ram 快過flash 係必然, 尤其係read , 至於acard, 有人試過架啦, 佢的而且確係可以去到sata 既最高速率, 但係要一隻acard 係要分兩條sata (即1.5g x2) 至去到3Gbps, 我亦試過個速度大約係咁.

所以比較既話, 最重要係raid 既分別, 我跟人砌server 大把情況係因為
raid card慢而令io timeout 既情況試過唔少.
用raid 1 甚至raid 5, 如果張card 慢, 係可以差好遠既.

你而家4 台adata , 1.5gbit x 8 如果raid 係可以做到line rate, 理論值係有12gbit, 減左parity 或者係error correction, 10gbit 係好合理值, 應該跟你張咭差唔到既.

我唔介意張ssd 快, 只係我覺得adata 用ram drive 夾 raid 可以不合理地慢, 有點怪.

我建議你如果可以借一張8port 既 sas raid (尤其係宣稱enterprise 走到全速果d),
試試走raid 試多次比較下

My boss said he also don't understand why ACARD DDR-2 Drive has such slow write transfer rate. If it is due to the poor performance of ACARD or the 3Ware RAID card, then why the read transfer rate is much faster than write? The difference between read and write performance of DDR-2 RAM should not be so big.

You are correct. Industrial or military grade products stress reliability even under hostile environment, therefore it doesn't necessarily mean they are faster than consumer products.

The problem is not ACARD in all situations slower than a traditional harddisk.
ACARD's read transfer rate is over 280 MB/s which is significantly faster than a traditional harddisk. The only thing which surprise my boss is that the write performance is only 78 MB/s which is the same as a traditional harddisk. With the same set up in RAID 5 mode, is there any reason that the write performance is significantly lower than the write performance?

---

作者: 凌天羽    時間: 2009-6-17 16:08



自己計了
write傳輸率只有75MB/s = single Western Digital 7,200 rpm Harddisk

行緊raid 5, 就係當佢走4 條sata, 100m cut 25% 做xnor image,
4 隻即係每隻write speed 係得25m
25mbyte 呢個速度絕對係連ide hdd 都快過佢..... 唔係, 係連cf card 都快過佢

如果係咁既performance, acard 無可能唔會唔知道卦

作者: 輕基黃    時間: 2009-6-17 16:27



But how can we explain the read speed is so fast under the same setup but the write speed is so low? Bearing in mind that, DDR2 ram should have greater write speed than SSD and traditional Harddisk.

There are two possibilities of causing poor performance of the write speed of the 3Ware RAID card + ACARD Drives RAID setup:
Poor write performance of 3Ware RAID card; or
Poor write performance of ACARD Drives in RAID mode.

Regarding the write performance of 3Ware RAID card, it has been utilized as RAID controller card for controlling 7 nos. of Western Digital Raptor 10,000 rpm harddisks in RAID0 mode before, the read and write speeds are more or less the same. Therefore, it eliminates the slow write performance problem is caused by the 3Ware RAID card.

既然部機係用得來試既, 拎走raid 試下咪知道acard 每隻既performance 咯,
isolate 左張raid card, problem isolation 呢一樣野我講左好多次好多次

你而家focus on 張raid card 無事, 仲搵hdd 來試張raid card 幾快幾快
但有無可能係一種情況係個ramdisk 太快, 結果raid card 因為io
頂唔順而出現大量buffer 唔夠而要discard data 然後retry 既情況?

事關raid card 設計果時未必係預左係用來行ram drive raid 咁誇張既快架
