Samsung SSD 830 256GB

OEM reliability arrives for consumer-class drives

TechRadar rating:

4 stars

A really strong consumer-level effort from Samsung, though the SSD 830 isn't the quickest drive around.

Overview

Samsung has taken the unprecedented move with its Samsung SSD 830 256GB of using its own individually created firmware, DRAM and NAND. Does that give it the edge?

Samsung has been overshadowed a bit by the likes of Corsair, OCZ and Kingston in the high performance SSD market.

The latter companies opted for the Sandforce controller in their drives and have hit perpetually impressive sequential read/write performance levels with each new generation, which makes them the go-to guys for enthusiast storage.

It's not like Samsung is a newcomer to the market though; far from it. Its OEM dealings with industry giant Apple contribute to a 26% market share in SSDs across consumer and OEM sectors.

The Korean powerhouse was also heavily involved in the early days of the SSD, providing reference designs which other manufacturers built their drives around.

The arrival of this consumer drive, the Samsung SSD 830, makes a lot of sense when you consider Samsung's know-how and quiet but significant involvement in the market.

Benchmarks

Industry leaders like OCZ's Vertex 3 Max IOPS make mincemeat of the SSD 830 in read performance and compressible writes, but if you move tons of media files around, you'll notice the SSD 830's superior incompressible write.

The triple core ARM9 controller is also a pro at multithreaded 4K random write performance. Those identical boot time scores show you how marginal the real-world performance difference is though.

Verdict

Unlike the competition, the SSD 830's controller, DRAM and NAND are all designed and built by Samsung itself.

That's surely advantageous when writing the firmware – if each component is built to get along with the others from the initial design phase, firmware can really zero in on performance and reliability.

It's the latter that Samsung is emphasising with this drive.

Multi-threaded 4k random read performance

Performance levels in the benchmarks we ran fell short of leading drives, but were especially impressive when dealing with incompressible data, which we'll cover later.

Without reliability though, these performance levels don't mean much.

SSD reliability is also the toughest aspect to get to grips with in a review. It's something that can be judged over months and years, not weeks.

Samsung's own test results show a 64 year lifespan for the SSD 830 with 10 GB written onto it each day, or 16 years with a rather improbable 40 GB daily write.

Those are really encouraging figures, and it's relieving to see reliability emphasized so heavily in a product type that hasn't always enjoyed the best *cough Sandforce 2200 series cough* track record.

The drive's firmware, which can be kept up to date by Samsung's Magician software, employs some nifty wear-levelling to avoid 'wearing out' blocks by writing to the same areas over and over. The firmware also runs a Sudden Power Off Recovery algorithm to prevent data loss if there's a power cut.

Sadly, we won't be able to see the fruits of these features until after a few months of heavy use, but current signs look encouraging and Samsung's pedigree in enterprise drives and extended OEM relationship with super-fussy Apple are good to keep in mind if you're looking for a dependable drive.

What we can talk about is performance.

549 MB/s read speeds for compressible data just about keep up with the quickest drives on the market, but the write speed of 407 MB/s falls back considerably.

However, the SSD 830 shines when dealing with incompressible (already compressed) data like media files.

It's the Achilles heel of the Sandforce controller, but certainly not Samsung's three core ARM9 controller which hits almost double the incompressible write speeds of competitors.

The Samsung SSD 830 isn't the quickest drive, but it deals well with incompressible data, boasts high IOPS and random read/write performance, and it's well priced.

If it's as reliable as it looks, the SSD 830 will be a fine long-term drive.

We liked:

With the emphasis on reliability in the Samsung SSD 830 that does give us confidence in the long-term use of this as a main drive.

The bespoke Samsung firmware also deals well with incompressible data, something traditional SandForce SSDs struggle with. The fact it can keep pace with the brilliant OCZ Vertex 3 Max IOPS in that respect is impressive.

We disliked:

Sadly, while it keeps pace it cannot best the performance of those competitors in compressible data.

Final word:

A really strong consumer-level effort from Samsung, though the SSD 830 isn't the quickest drive around.
