Hello to all.I want to buy an ssd for my computer.It's a SATA II.I want to buy one with 120GB,for upgrade to Windows 8 or 8.1 and install there my basics applications.
I am searching but I can't decide if to buy Samsung 840 Evo or hyperx 3k
Thanks for helping me
Buy the cheapest. You really will not notice any difference. My favorite is this one:
Mushkin Enhanced Chronos MKNSSDCR120GB 2.5" 120GB SATA III MLC Internal Solid State Drive (SSD) - Newegg.com
So,buy the samsung,is the cheapest.But If I upgrade the pc (that I think I will change it in one or two years,because this is 6 years old,but runs like a horse :) ),Will I feel the speed on a sata 3 computer??
You will notice the difference in speed on any computer. Sata2 or Sata3 does not make much of a difference for the OS. Just make sure you don't run it with XP. That has no TRIM support.
If the Samsung is less than the Mushkin, get the Samsung. In a few years we may have a whole new SATA interface that's 10 time faster.
XP and SSD's are fine, all current generation SSD's have GC (garbage collection) imbedded in the firmware, GC is the process of relocating existing data to new locations and allowing the surrounding invalid data to be erased. Flash memory is divided into blocks, and blocks are divided in pages. Data can be written directly into an empty page, but only whole blocks can be erased.
The advantage of the TRIM command is it enables the SSDs GC to disregard the invalid data and not move it, saves rewriting the invalid data. This reduces the number of erase cycles on the flash memory. The SSD doesnt need to immediately delete or GC these locations, just mark them as no longer valid.
That is not my understanding on how it works. But maybe you are right.
