Given the relative rarity of high-capacity 1.8" SSDs and the m4’s solid track record, Crucial could have likely gotten away with charging a slight premium over its 2.5" iteration. Currently, it seems the 1.8" m4’s primary competition comes from SandForce SF-2281-based drives such as the Mushkin Direct Atlas Deluxe mSATA 240GB, which costs slightly more at $230. With high marks in both price and performance, the m4’s reliability is the only factor that remains unaddressed, and in my opinion, Crucial also scores very highly here. Since its release, I’ve owned many m4s and all of them remain in use today with nary a hiccup. Crucial has been quick to patch bugs and they’ve worked hard to hone the drive’s performance. From what I’ve seen of the company’s support, the m4 would definitely be toward the top of my list if I were going to invest in an SSD today.
Cons: If you don’t require the small footprint, there are other equally attractive SSD options on the market.
