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.
|Data Rate||6 Gb/s||6 Gb/s||6 Gb/s|
|Capacity||128 GB||120 GB||128 GB|

|Price per GB||£1.07||£1.48||£1.37*|
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. 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. Tom's Hardware US was 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, which currently retails for $230).
*UK pricing for the 830 series is not yet available. Considering pricing is thought to be similar to the 470-series, we've taken the most up-to-date price for the 128GB 470 series and will be using it just for the sake of having some UK numbers to work with. We'll update this story with the appropriate 830 series pricing if and when we can get that information from Samsung.
