Reviews Word on the street for the Samsung 470

We'd like to see what else Samsung can produce, and whether it can stay competitive on the SATA front, but the 470 represents an excellent start.

SSD technology is moving fast, so any brand new drive is always attractive.

What People Are Saying Give it to me straight


Barring more data on long-term performance, we have no hesitations recommending the 470 Series to anyone looking to upgrade.

Benchmark Results: A very clean and smooth graph indicates consistent performance but this is the first benchmark to show read scores falling below rated specifications.
by Legit Reviews (Jan, 2011)
Writes did exceed the specification and overall performance was excellent.
by Legit Reviews (Jan, 2011)


The 470 Series chugged right along here exceeding rated specifications for both reads and writes while posting some of the best scores of any SATA II based drive - especially in the sequential writes.

Back in January following CES, we had a look at Samsung's 470 Series SSD which performed very well in our tests in comparison to other SATA II drives.
by Legit Reviews (May, 2011)
Interestingly, on the last test, the Samsung even surpassed Intel's 250GB SSD 510 Series, which also uses 6Gbps SATA (Intel managed only 77.38).

Being one of the newer drives on the market, the price is going to reflect a premium and we'd expect to see that price to drop as supply increases.
by Legit Reviews (Jan, 2011)
At a cost of $2.04 per usable GB, the price is pretty much in line with what we see with its competition.
by Legit Reviews (Jan, 2011)
The cheapest we could find the 256GB version online is $486 but in many places it is selling for over a hundred dollars more.
by Legit Reviews (Jan, 2011)


The 4k read/writes weren't quite as fast as the other drives but they are in the ballpark and as such, the overall score fell a little short of what we see for some of the better drives in the comparison.
by Legit Reviews (Jan, 2011)
The drive was completely filled with media on a few occasions while traveling which triggered a slow down in performance mainly because OS X does not support TRIM.
by Legit Reviews (May, 2011)
Though the line is based on 3Gbps SATA II rather than the newer and faster 6Gbps SATA III standard, the 128GB model we tested (priced at $299 list) ran impressively—in some cases beating the results we saw from the more established players in the field.
by PCMag (Jul, 2011)


The drive was loaded to about half full with 112 GB of capacity used with apps, games, photos, movies and other content making it representative of a normal user's system and in fact, it is a normal user system - mine.

After Windows takes its administrative cut and the chunk set aside in overprovisioning, the user is left with 238GB usable space.
by Legit Reviews (Jan, 2011)
This means Samsung is putting its name and reputation on the line, which is potentially risky for a company that's not well known for these types of products in the consumer space.
