Solid State Drive/Windows 8
Gene E. Bloch wrote:
On 11/16/2012, Boris posted: I bought a Win 8 Toshiba ultra laptop with a SATA 500GB drive and a solid state 32GB drive. The description says the solid state drive is for the OS use only: http://www.toshibadirect.com/td/b2c/...oid=2000040281 My question is, do I install the apps on the SS drive? And if so, do I need to change any folder settings, or do I just direct app installs to the proper drive letter designation? I haven't even turned on the laptop yet. Win 8 is new to me, as is the best use of solid state drives. TIA After reading this thread and after (finally!) reading the specs on the Toshiba site you linked us to, I side with all of the people who say that your 32 GB "SSD" is *definitely* a cache built in to the 500 GB drive and it is *definitely* not accessible to you. Here's a copy and paste directly from the specs on that site: "Hard Drive 500GB HDD (5400 RPM, Serial ATA) with 32GB (system use only) solid state disk cache" No. It's not inside the hard drive. It's a separate device. Why do I say that ? The Toshiba site offers the Intel RST driver for that computer. You don't need the RST driver for a single hard drive (as you propose). Therefore, this is the (chipset licensed) software cache feature built into the RST driver, which uses a small SSD combined with the hard drive. On hybrid hard drives, if you look at the specs, a hybrid uses less flash than that. Example of a 2.5" hybrid. http://www.newegg.com/Product/Produc...82E16822148591 "Solid state hybrid drive with 4GB solid state memory delivers SSD-like performance with hard drive capacity options." The OP has also stated, that he sees a "RAID 0 disk listed, which is disconnected", and that is a side effect of the RST option to split the cache SSD in two (unequal) pieces, using part of it for regular storage, and part as cache. The portion of the SSD allocated for regular storage, becomes a "single disk RAID 0" according to Intel. So the evidence lines up with the Intel description of that caching feature (SSD+HDD, two drives). The "RAID 0 disk listed, which is disconnected" will magically be reconnected, when the OP enters the Intel RST control panel, and reduces the setting for the size of the cache. The evidence suggests currently the entire 32GB is set up as cache, and 0GB is set for regular SSD usage. And at 0GB, the "RAID 0 disk listed", ends up disconnected. This is all trickery by the RST driver. And it only is licensed to work with particular chipsets. Since it's a software technique, it would probably work everywhere otherwise. It doesn't rely on hardware. Paul |

Paul http://www.newegg.com/Product/Produc...82E16822148591 I thought it might be better to see what Seagate has to say, rather than go through an outside agency (i.e.Newegg). This is Seagate's page for the above drive: http://www.seagate.com/internal-hard...tus-xt-hybrid/ but that seems to be the same as Newegg's data. The Seagate page points to this, which might be more marketing than explanation: http://www.epageflip.net/t/26941/22 Unfortunately the web designer for that page thinks tiny pale blue and pale grey type is cool. I can't quite read it :-( -- Gene E. Bloch (Stumbling Bloch) |

And make it so hard to get to. I had to use Firefox in Ubuntu, to get an actual link I could use. Download is 44.9MB or so. For some reason, my browsers in Windows were giving me a hard time. This is a line from the doc... "Adaptive Memory technology makes such efficient use of the drive's solid state memory that only 4gB to 8GB of flash capacity is actually needed." Roughly translated, "that's all they were willing to spend". Paul |
