throwing up hands in disgust, which of these is best?

Recommended Posts

i give up on the crappy uli controller. it wasn't even letting me boot into windows. which of these is best?

 

http://www.newegg.com/Product/ProductList....tk=&srchInDesc= 2 port sata pci-e 3.0 controller or

 

http://www.newegg.com/Product/Product.asp?...N82E16816115029 cheapest 4 port one.

 

i'm getting 2 new harddrives so i'll need 5 sata ports and i don't want to touch the uli one. anyone?

I have both of those cards, the highpoint is a great card but the SIL3132 based card works just fine. Which one to buy depends on how many drives you want to run in RAID. If you just need 2 in RAID buy the Syba..

Splitting four SATA ports on a 266 MBps interface is a not the best idea.

 

Would you rather each drive have 133 MBps, or would you rather each drive have 66 MBps?

 

I have a syba model that is $20 that I got off of ebay using the Silicon Image 3132 chipset. It is recognized under linux after enabling a few options in the kernel.. if it works there it'll definately work in windows. 2 port, PCI express. I highly recommend it.

 

Buy 2 two port cards instead of one four port, this way each drive gets more bandwidth.

its a 4x card for the 4 port card. that means 2,000MB/s for 4X. 300x4=1200. i don't see that as being saturated ;). even if you just count one way, which is 1000, thats still 250 per port. hardddrives don't max out the 3.0 spec i believe ;)

2x = 250 MBps, so wouldn't 4x = 500?

 

I'm not implying you're wrong, I'm just curious how this works... if you're right, my next card will certainly be a four port sata.

pci-e is bidirectional, whereas agp wasn't. :)

 

The basic "x1" link has a peak raw bandwidth of 2.5 Gbps. Because the bus is bidirectional (that is, data can be transferred in both directions simultaneously), the effective raw data transfer rate is 5 Gbps. Table 2 summarizes the encoded and unencoded data rates (see sidebar, PCI Express "Coded" and "Unencoded" Bandwidth) of x1, x4, x8, and x16 implementations, which are defined in the initial generation of PCI Express.

 

Table 2: PCI Express Bandwidth

 

PCI Express Implementation Encoded Data Rate Unencoded Data Rate

 

x1 5 Gbps 4 Gbps (500 MB/sec)

x4 20 Gbps 16 Gbps (2 GB/sec)

x8 40 Gbps 32 Gbps (4 GB/sec)

x16 80 Gbps 64 Gbps (8 GB/sec)
