Puzzling SSD Tests with Older Computers
This has included two 2008ish Core 2 Duo 3.0 ghz (E8400) desktops, and my mother's 2011 Samsung laptop with a B950 dual core processor. . In installed an Evo 850 in both the desktops, and a Sandisk SSD plus in the laptop. These installs went pretty well.
On the desktops, the desktops, the computer finishes booting after the Windows 7 "pieces" have just touched. On the Samsung laptop, the pieces get 1/2 to 3/4 of the way touching, then it boots.
So this Toshiba laptop is no more than a year older than the Samsung laptop. It has a P6200 2.13ghz processor, and the benchmarks are very close to the B950. I think it's like 1700 to 1600 or something.
I bought the ADATA SP550 240gb for this computer, and installed all the drivers. This includes the Intel Rapid Storage Driver, the AHCI driver, the chipset driver, and all the correct stuff. I've done this a couple of times now. Well on this computer, the Windows 7 pieces come together, then it hangs for another 5 seconds, then boots. The computer boots up in 20-25 seconds, which isn't terrible, but wayyyy slower than the older desktops and the Samsung. Chrome takes 2-3 seconds to load as well. It's not instant like it is with the other computers.
So I bought another Sandisk SSD plus just to compare. The Sandisk actually feels a tiny bit faster. It only hangs for 4 seconds rather than 5, and Chrome seems to open in 1-2 seconds, rather than 2-3.
I've benchmarked both drives, and the Sandisk has a slightly better Sequential read, but the ADATA has better random reads. Random reads are supposed to be what makes the computer boot faster supposedly.
For kicks, I tried the Sandisk drive in my Lenovo laptop, which is about the same age as the Samsung from before (B940), and it booted halfway through the pieces coming together. After doing a full restore, it took until the pieces colliding again.
Sequential reads were 500 on the benchmark, so I'm thinking okay this computer has SATA 3 then. But the sequential write was 200, which was the same as on SATA 2.
So yeah, I don't get it. Is there something wrong with my ADATA drive? Is there something I can do to make the Toshiba faster?
The ADATA has really slow write speeds, but that doesn't really matter for a computer that just does web browsing right?
I've attached an image with the 3 benches.
