Posted October 16, 2014 by Sandy Bruce in Storage, HDs & SSDs

Overview

Hardware:
 
Manufacturer:
 
Release Date: Currently Available
 
Price at time of Review: $140
 

WHAT WE LIKED:

Smaller size, easy to install, consistent speeds, price compared to other M.2 drives
 

WHAT WE DISLIKED:

Price compared to Standard SSDs, Speed largely unchanged from Standard SSD
 
BOTTOM LINE:
Overall there are just enough benefits to justify the $20 average premium for using M.2 instead of a standard SSD. We are just now stepping into the M.2 era and the SP900 is a good stepping stone.

Introduction

0923141908a

There has been a lot of anticipation for M.2 to be fully released upon the masses. Well folks, we are still waiting. With only a handful of M.2 compatible drives available choices are limited. Apparently, it’s better than having a bunch of motherboards available, but no M.2 devices to choose from (Z97 release day). So now that Intel’s newest flagship platform has shipped we are starting to see more M.2 SSDs on the market. There is still not an abundance of choice or enough to continue the downward push of SSD prices, however we see light at the end of this tech tunnel, even if it’s just a little further than most of us would like. ADATA, a leader in memory technology, sent us one of the two types of M.2 drives available, the SP900 256GB M.2 SSD.

Here is a little about ADATA and what they do… then we can move on to learn about M.2.

    I’m confused by the bits to bytes conversion this site is using for SATA speeds. Why would 6 gigabits/sec equate to 600 megabytes/sec? One byte is eight bits, therefore 6 Gb/S would be approximately 750 MB/s. Are you trying to get closer to real-world speeds due to overhead? If that’s the case, the overhead shouldn’t increase for higher speeds, so one wouldn’t expect the 10:1 ratio you use for faster speeds bits to bytes. Is there some new piece of tech info I’m missing?

      You are overthinking it a bit. It’s simply generally accepted in the PC industry that for simplicity’s sake we use a 10:1 ratio. We all know that binary doesn’t equate that way, but it makes it less confusing for the lay person and makes for quicker math that is roughly equivalent.
