Someone recently told me that if you have an SSD and a hard drive plugged into your motherboard the hard drive will slow the ssd down, anybody know if this is true or not? Or is it total codswallop?

i7 950, Asus Sabertooth X58, Noctua NH D14, 1x Zotac GTX 580, Corsair 6gb Dominator 1600Mhz, Crucial C300 128GB, Samsung Blu Ray DVD/CD/RW, Enermax Revolution 85+ 1050W, Corsair 800D, Windows 7

Hi,

The only thing I can see is the hard drive bottlenecking the SSD when coping to and from the hard drive. The SSD will only go as fast as your hd can go. Other then that, I don't see how a hard drive could slow down the SSD.

Nope. Having an HDD and an SSD connected to the same SATA controller won't affect one another's preformance.

pretty much there is only one way a hdd will have a negative effect on ur system, is if u make hdd store the virtual memory and disable the os from make virtual memory on the ssd. This would force ur system to take some data from the slower hdd and the faster ssd at the same time. which creates what most novice users call slowing down the ssd. (mainly a bottle necking of the hdd which hinders the performance of ur ssd when ur system accesses virtual memory). Why people do this is to prolong the ssd life without buying more memory.

u can avoid all this by disabling virtual memory all together but i recommend u get a minimum of 4gigs of ram before u do it.
Keep in mind that ur system might close apps if u exceed the total amount of ram u have, since it has no way to create virtual memory.

Some programs rely on the virtual memory so I'm not sure if it's wise to disable it altogether.

Besides, if you install Windows on the SSD, wouldn't it create the swapspace on the SSD as well and leave the HDD alone (and thus don't cause any bottlenecks)?

Yes, it automatically allocates space for virtual memory, but u can disable it. Having it on the ssd will shorten the life span because a sector can only written over so many times before it dies.

Any program can run with no virtual memory, I run my system with no virtual memory because i got 6gb of ram.

Virtual memory is used mainly as a back up or if u run out of physical memory.

If u have it enable windows will use it. (default)

If u disable it windows will only store data on ram for quick access. (so if ur system eats up all the ram and wants more it will close apps to get it space on ram)

recommended to disable virtual memory for ssd.
right click mycomputer > properties > advance tab > click setting for performance > advance tab and u change virtual memory.

Anyway the question he asked is if its possible not whether windows defaults it virtual memory to ssd. For some who doesn't know how play with virtual memory then its impossible unless ur os isn't on the ssd. It possible if ur cheap on ram and knows how to move virtual memory to a cheaper hdd rather than a ssd where ur os is.

I recently installed a new SSD (RevoDrive) on my system. When I started windows up with only that drive connected it would load up within 30 seconds. Then I added a 1TB drive (7200 RPM) for other files and backup, no system files (although backup may be counted as a system file), and once I had that installed my startup went from 30 seconds to around a minute and a half and more.

well that is very common that start up get time gets increased with hdd and even when the hdd is hooked up by usb. This is due to prefetch and superfetch caching ur hdd on start up. But u won't feel that once windows is loaded.

I suggest as alwaus having the SSD acting as the operating system and the hard drive for backing up or saving personal stuff.
