The laptop has no express-card slot, but has eSata + 2 x internal SATA ports + mSATA ... so plenty of SATA here. However these are not high end dedicated SATA card and I'm not sure of their NCQ support. What would an ExpressCard-eSATA bring to the table ?
Anyway, shouldn't a couple of 1TB Samsung 840 EVO (low latency) SSD, capable of 100,000 4k random reads, do well enough on integrated SATA ports ? And beyond laptop requirements, could these recent disks possibly ditch an array of two years old SSD ? Besides, I still wish someone could share its experience, and proper Kraken results (or shortcomings) with Radon 5xxxM ou 6xxxM laptop GPU, compared to CPU only. ---------------------------------------- > Date: Sun, 6 Apr 2014 14:30:28 -0700 > From: [email protected] > To: [email protected] > CC: [email protected] > Subject: Re: [A51] 6990M mobile GPU > > On Sun, Apr 06, 2014 at 09:35:17PM +0200, Malak Leman wrote: >> Since a laptop can't get a dedicated SATA card and an array of disks, >> what kind of performance per burst can be expected with this GPU and 2 >> x 1Tb SSD ? > > You can use an ExpressCard-eSATA card and two (or more) external disks, > such as http://www.newegg.com/Product/Product.aspx?Item=N82E16839158039 > > You should be able to do about 400 MB/sec through that card, limited by > the PCIe 2.0 x1 link from the expresscard to the CPU.
