Cheap PCIe SATA III card for a 500 MB/s SSD disk

Hi,

 

I'd like to hear from your experience regarding a PCIe SATA III card for G8.

 

My requirements are:

- cheap

- full 500 MB/s for 1-only SSD (500 MB/s) drive

- Vmware ESXi (un-officially) compatible

- bootable

 

I bought this one:

https://www.amazon.es/gp/product/B00BI4Z51Q

 

I only get ~350 MB/s read and 250 MB/s write (due to poor chipset performance, I think; it has a Marvell similar to Asmedia one).

 

Any chance to get a cheap PCIe card which gets the real 500 MB/s speed?

 

Cheers,

How are you testing the speed and what model SSD do you have?

I assume you have the front bays full of disk drives and want to run the SSD from a faster port than the ODD SATA port?

My first choice would be an LSI based card flashed to the IT firmware. The IBM M1015 and its LSI equivalents seem to stay around $50 on ebay.

Depending on where you live, Shonk found LSI SAS 9207-4i4e at a great price:

Plus ESXi likes LSI cards.

@rivest: Which SSD do you have and what speed are you getting with 1062R?

 

@schoondoggy:

- my SSD is: Crucial MX300 SSD 750GB

- speed test is very rudimentary, for instance, for getting write speed, I boot a Linux rescue disk and then:

# dd if=/dev/zero of=kkkk bs=1M count=100

(where kkkk is located on fs inside SSD)

- yes, I was using ODD SATA port, but: 1/  it's slow (SATA II) for my SSD, 2/ I wanna pass-through (VTd) the entire Gen8's SATA controller (Intel Cougar) to a VM running Xpenology, while having PCIe' SATA controller running the SSD for ESXi system+datastore (with VMs).

- I only need one SATA III port (stable&performant; no hw RAID, etc), so I was looking for a cheap card.

- I'm based in Spain.

 

Cheers.

Would you recommend something like this?

http://www.ebay.es/itm/NEW-LSI-SAS-9207-8i-SATA-SAS-6Gb-s-PCI-E-Host-Bus-Adapter-LSI00301-/252308489503?hash=item3abec2051f:g:OSQAAOSwAuNW2SrD

The fact it's shipped from HK (China) scares me a little bit (may be it's a fake? :??? or is it right to buy it?).

Btw, this solution seems kinda overkill because at the moment I only need 1 sata extra port (I'll need to spend additional 10 eur to buy a SFF-8087 to 4xSATA cable) but I guess it will be rock solid (and permits expansion in the future) so I'll probably go for it.

What do you think?

Cheers,

The 9207-8i is a great card. I think a 9207-4i4e would be more useful in a MicroServer. 

As far as fake cards I have no insight. I have bought all of my LSI based cards from US sellers and they are all OEM(Dell-Fujitsu-IBM) or system pulls.

What's the difference between 8i and 4i4e and why do you think it's more useful the later for MicroServer? (and what about price difference? is it huge?).

Acording to the table in this article, they only differs basicly in connectors type and the external connector (that 8i lacks). Other features, including fw, it's the same, am I right?

Thanks again for your responses. They're greatly appreciated!

The "8i" indicates eight internal ports (2x 4 lane connectors). The 4i4e indicates 4 internal and 4 external ports (1x 4 lane connector of each).  

So the reason that the 4i4e cable would be more useful, is that you can connect external drives up here. You can get SFF-8088 (external connector) to eSATA breakout cables (4x eSATA) or you can get a SAS JBOD enclosure that can hold 12+ drives, depending on the enclosure.  Meaning that if you need to expand significantly, this card is the way to do it.  

And as for quality, schoondoggy is right. LSI is rock solid, and a well supported brand. They're main focus is enterprise, and their quality is absolutely fantastic.  

As for fakes, other than a visual inspection of the card compared to a 'real" card, there is no real way to tell.  My suggestion, don't buy from a chinese seller. You reduce the risk of getting a fake that way.  Otherwise, it's a gamble.
