As the title says, I am wondering because I saw a SD to SATA converter on peebay for $10. In terms of speed, what is the order of: a mechanical HDD, a SD to SATA drive, and a typical SSD? I know there are different SD cards with varying speeds, assume it is the cheapest kind since the fastest kind is about the same price per megabyte as a SSD. Is a SD to SATA drive even worth getting over my current SATA HDD (200 GB, 7,200 RPM)? I am planning to install either Windows 7 32-bit or Ubuntu. I just want a cheap performance boost to a PC that will be used as a HTPC/DVR.
It is an HP Pavilion a1120n with a Pentium 4 3.4 GHz. The motherboard is a Asus PTGD-LA aka "Goldfish3" and since it was made before 2005, I am assuming it is SATA 1.5 GB/s. Will any SATA SSD work on it, or will it need to be a SATA I?
Thanks for any input.
Edit: I also found this. The $10 adapter can only do up to 32 GB and 22 MB/s. This can do 4x 32 GB in RAID0 and up to 80 MB/s. I'm guessing those are write speeds.
SATA-1 up to 150
IDE/PATA up to 133 depending on drive and chipset
For you motherboard, a cheap Vertex 3 / Agility 3 will provide more speed than the SATA-1 can handle.
Thanks. I was assuming that an SD card, being a type of solid state storage, would be faster than a spin drive, but I now I am no longer even considering it. There is no reason for a SD to SATA adapter other than needing silent operation for less money than a SSD. Since most the adapters are the size of a SSD, one of the reasons isn't even form factor. I will turn my attention to a cheap 32 or 64 GB SSD, possibly a SATA II. I have seen some good deals on refurbished 3.5" SATAII OCZ drives. Recently a 120GB was around $60 and a 64 GB was in the $30 range on newegg. When you say it is "more than my board can handle, does that mean my SATA controller will down-convert to SATA I, or that it will not work at all?"
