Samsung's 830 is a late entry to the 6 Gb/s SSD market, but the company claims impressive performance. Can it unseat the incumbent SandForce-based drives? Let's just say this new offering shakes up the SSD world in a major way. Other vendors, beware.
Despite the number of different companies selling an even more expansive list of SSD brands, you really have to boil solid-state storage down into controllers, NAND flash, and firmware. Of course, it's the controller that defines most of a drive's performance attributes and features. More often than not, comparing SSDs based on the same controller hardware yields minimal deviation. We only needed to compare OCZ’s Agility 3 to Corsair’s Force 3 in our recent second-gen SandForce round-up for proof.
If a controller is an SSD’s real foundation, then we're principally looking at a battle between a handful of different companies and their technologies. However, only SandForce and Marvell are currently shipping 6 Gb/s-capable controllers. Remember that Intel leans on Marvell's silicon for its SSD 510, and not its own proprietary design.
| Samsung 830 | 64 GB | 128 GB | 256 GB | 512 GB |
|---|---|---|---|---|
| Interface | SATA 6Gb/s | SATA 6Gb/s | SATA 6Gb/s | SATA 6Gb/s |
| 4 KB Random Read | 75 000 IOPS | 80 000 IOPS | 80 000 IOPS | 80 000 IOPS |
| 4 KB Random Write | 16 000 IOPS | 30 000 IOPS | 36 000 IOPS | 36 000 IOPS |
| 128 KB Sequential Read | 520 MB/s | 520 MB/s | 520 MB/s | 520 MB/s |
| 128 KB Sequential Write | 160 MB/s | 320 MB/s | 400 MB/s | 400 MB/s |
Samsung is showing up a little late to this battle with its 830-series SSD. However, those specs it's citing (above) are downright impressive. Across all capacities, we’re looking at sequential read speeds of 520 MB/s and writes as high as 400 MB/s on the 256 and 512 GB models.
This puts the 830-series in the same league as SandForce's second-gen controllers. Perhaps the most significant difference, however, is that Samsung's logic doesn't depend on compression technology, whereas SandForce's DuraWrite "optimizes the number of program cycles to the flash" with the purpose of extending write endurance. As a caveat, however, incompressible data doesn't enjoy the architecture's peak performance (which is, of course, what drive vendors like to cite in their spec sheets).
By delivering its performance without a suite of marketing terminology, Samsung is forced to use higher-quality NAND to deliver the same level of write endurance. However, its 830-series should also be more consistent. Fortunately, Samsung is one of the only companies able to leverage its own controller, its own firmware, and its own flash memory in the same device, giving it a substantial cost advantage over companies that have to buy third-party controllers, someone else's NAND, and modify a reference firmware.
| Brand | Crucial | OCZ | Samsung |
|---|---|---|---|
| Model | m4 | Vertex 3 | 830 |
| Data Rate | 6 Gb/s | 6 Gb/s | 6 Gb/s |
| Capacity | 128 GB | 120 GB | 128 GB |
| MSRP *subject to change | $225 | $230 | $250 |
| Price per GB | $1.75 | $1.92 | $1.95 |
If that’s not enough to shake up the SSD scene, the prices Samsung says to expect its 830-series drives to sell for should give the company's competitors a reason to take notice. We're told that the 128 GB 830-series drive should sell for $250. That’s a little under $2 per GB (right in line with OCZ's 120 GB Vertex 3).
Samsung is withholding pricing information for the full product line, but prices should be similar to the 470-series, which the 830 is expected to replace.

It boils down to reliability, not one hiccup on M4 yet (or any crucial drive Ive installed), 4/5 Sandforce drives I have installed have had some form of callback problem to resolve once deployed, mostly requiring firmware updates, but a few failed drives as well!
Mind you, still better than the early Corsair force Series I used, every single one failed! Stopped using them quick!
Am tempted by OCZ, once they have reliability on their side I will give them a go again!
I saw this quote below in the summary and laughed as nobody in there right mind would use a basic MLC drive in a database server. So Samsung tuned the drive for what it will be used in ,desktops, good.
"Although we'd probably think twice before picking this as our first choice for a database server, it does just fine in an enthusiast's machine."
Proof? I think you just pulled this out of your ass or from someone's that told you some story. The 470 series was VERY reliable.
7mm but it comes with a spacer to fit 9.5mm
Even today, I would NOT use OCZ drives on any computer. Yeah, they are generally the fastest drives on the market, but I'd rather get an intel, even an M2-X25. The return rates for ALL drives, other than intel... are bad. Samsung is worst in performances and tools. But this new drive... we'll have to see over time.
Really? Hmm, this is the first time I heard something negative about the 470series SSD. Everytime I read a SSD article the 470series always had good reviews on solid reliability.
I have googled every which way and cannot find any references to any major problems or issues with the 470 series that is similar to what other brands have been going through.
