SSD and traditional HD together: drawbacks & advantages?
I am reviewing a good introductory article on Solid State Drives in Maximum PC Feb edition.
They mention if you have lots of data, you can put a traditional mechanical HD as your "D" drive and use the SSD drive as your "C" drive. Advantages? I guess you save money in not having to pay for a much bigger SSD drive. Disadvantages? Are you not stuck in a bottleneck? Maybe not so much though, since with SATA drives (my mobo is SATA), with the mechanical drive at 3 GB/s and the SSD drive at 6 GB/s, you'll have programs load faster, and a bit slower when said programs access the data, is that right? But how much slower? I hate for the old mechanical HD to become a bottleneck. Also of interest is that TRIM command (which is redundant somewhat to the built in commands for garbage collection in SSD drives) is not really well supported in Windows 7, but more so in Windows 8. Further, the bigger the SSD capacity the faster, since the SSD controller does not have to erase sectors as much before writing to them with big capacity drives, which have more unwritten sectors than smaller drives, but can erase the data later, and this increases throughput. I might buy an SSD drive, but if there's a bottleneck as I describe above I might wait until prices fall a bit more and wait until early 2015 when SATA Express interface comes out, which has a faster than present 520 MB/s throughput for SSDs.

They mention if you have lots of data, you can put a traditional mechanical HD as your "D" drive and use the SSD drive as your "C" drive. Sure, I've got something like that setup here, I actually have an SSD being my C drive, with about 6 other mechanical drives accompanying it. Advantages? I guess you save money in not having to pay for a much bigger SSD drive. Disadvantages? Are you not stuck in a bottleneck? Maybe not so much though, since with SATA drives (my mobo is SATA), with the mechanical drive at 3 GB/s and the SSD drive at 6 GB/s, you'll have programs load faster, and a bit slower when said programs access the data, is that right? But how much slower? I hate for the old mechanical HD to become a bottleneck. The vast majority of the disk accessing goes to the operating system itself, and it's mostly accessing its own files. That creates the major requirement for the SSD. It's sufficient to simply put the Windows OS and its programs under the SSD, to notice a huge improvement in responsiveness. Also of interest is that TRIM command (which is redundant somewhat to the built in commands for garbage collection in SSD drives) is not really well supported in Windows 7, but more so in Windows 8. Further, the bigger the SSD capacity the faster, since the SSD controller does not have to erase sectors as much before writing to them with big capacity drives, which have more unwritten sectors than smaller drives, but can erase the data later, and this increases throughput. Why do you say that Windows 7 doesn't have support for the TRIM command? It was Windows 7 that introduced support for the TRIM command. It was XP that didn't have any support for TRIM. I might buy an SSD drive, but if there's a bottleneck as I describe above I might wait until prices fall a bit more and wait until early 2015 when SATA Express interface comes out, which has a faster than present 520 MB/s throughput for SSDs. There's always going to be something faster or bigger around the corner. Yousuf Khan |

Some potential disadvantage in standards and firm interfaces, i.e. - I'm running a SSD boot arbitrator on an older MB, early Intel dualcore, which wasn't easily accomplished. Pure silicon zipity-zap data rates trumps all else in sum from _The Idiot's Guide to SSDs_, once working, setup;- Tweakdom World, W8.1, TRIM, are hmmm's and humjobs for some rainy day when maybe I get my thumbs out of my butt and update. Get two in case you've two computers. One's missing in mine from a Samsung SSD 64G, mostly data free, on a sale for $40US. (More reason, best I can figure, for more work or something like that.) |

There were SSDs before a larger W7 presence today. Manually is one way, such as a reformat, drive/partition assignments - various storage forums, I'm sure on a Google search, will recall the methods;- manufacturers, too, as in the case with my model's inclusion, on a provided CD, for running Samsung's transposition or approximation of W7 TRIM within a minimum of XP/SP3 environ. Haven't personally tried it, given it a spin, eh, yet. |

Yeah, there were various utilities that were installed under XP to intercept the OS call and send the TRIM command to the SSD. But even without the TRIM command, garbage collection still can happen in an SSD, it just won't be as fast or efficient. Yousuf Khan |

I guess you save money in not having to pay for a much bigger SSD drive. Disadvantages? Are you not stuck in a bottleneck? I have a 256gb SSD for my C drive, containing the OS, applications, current steam games, along with dual 3tb HDs in mirrored raid 1 for my D drive. First off, cost is a huge factor, and why I went with SSD + raid HDs. At current prices, 3tb worth of SSDs in raid 1 (aka, six 1tb SSDs) is close to $4000, compared to just $300 for a pair of raid ready 3tb HDs. Second, you don't notice the slowdown for the HD, because the music/videos/data that you put on your D drive is not speed dependent. Data is the easiest to show, as most personal data files are small. Even a 50 mb file can be read off an HD in half a second. Thus, the time wasted to read it from the HD is small enough that it's not noticeable in real use. Videos, even bluray videos, are designed to be read from optical disks at a mere 7 mb/s, in order to get flawless playback. Uncompressed music off CDs are designed to be read at an even slower 2 mb/s. Since HDs have a read rate of about 100 mb/s, you end up loading videos 10x faster than you can play them, and music is loaded 50x faster than you can play them, as videos/music apps are designed to play and read at the same time. Which is why you don't notice the speed of videos/music playback when stored on your HD. The only time you ever notice a performance hit is if you do video editing or photoshop editing with many layers. Remember that videos/music/data is not like the OS or games, which want to randomly read in different parts of the OS/game all the time (which is where SSDs shine). For videos/music/data, your HD ends up just loading in one file, then goes idle, while you finish watching the movie/listening to the music/working on a document, before loading in another file. I might buy an SSD drive, but if there's a bottleneck as I describe above I might wait until prices fall a bit more and wait until early 2015 when SATA Express interface comes out, which has a faster than present 520 MB/s throughput for SSDs. An SSD for your OS/games is one the biggest upgrades you can get for your computer. It's more noticeable than a CPU upgrade or a video card upgrade. Everyone who buys one would never go back, at least not willingly. -- // T.Hsu |
