Toshiba THNSNH512GCST review: a SSD with mostly good Lab results

£380 inc VAT

Manufacturer: Toshiba

Our Rating: We rate this 3.5 out of 5

The Toshiba THNSNH512GCST doesn't help promote itself with its unpronounceable name, and the warranty of just one year doesn't inspire confidence either, that said its Lab results were mostly very good. Read our Toshiba THNSNH512GCST review to find out me.

Toshiba THNSNH512GCST review

You could be forgiven for thinking that Toshiba ought to be leading the pack in solid-state drives – after all, the company invented NAND flash back in 1989. But until recently, Toshiba had been more focused on supplying semiconductor storage to enterprise customers, and is almsot unknown for its consumer SATA SSDs. See all Storage reviews.

The Toshiba THNSNH512GCST doesn't help promote itself with its unpronounceable name, and the warranty of just one year doesn't inspire confidence either. As for firmware support, there is none offered to the end user, although we're told that when revised firmware becomes necessary Toshiba will ensure the tools will be made available. We're awaiting clarification whether such support will also necessitate a Windows PC. See Group test: what's the best SSD (solid-state drive)?

Inside the THNSNH, as those on more familiar terms might call it, is Toshiba's own 19nm MLC flash and a controller that features the company's Quadruple Swing-By Code (QSBC) for read-error correction. Advanced power mangagement is said to ensure the lowest energy consumption, an important consideration for laptop use. Take a look at the Corsair Neutron GTX 240GB SSD review too.

While Toshiba has hitherto been supplying SSDs to the trade, the sample of this new consumer drive was similarly bereft of any packaging, accessories or even labelling.

Lab results were mostly very good, leading with near-100,000 IOPS from CDM's 4k random read test (98.5k). AS SSD showed an interesting and strong bias toward read performance, hitting 92k IOPS while 4kB random write IOPS languished at just half this with 49.1k IOPS. AS SSD also scored the Toshiba well, scoring 954 points, albeit putting it in fifth place in this competitive group.

CrystalDiskMark confirmed that no conspicuous data compression techniques are employed, with the 503/477 MB/s read and write result barely moving when switched to incompressible random data: 501 and 473 MB/s. The headline sequential results from ATTO were also among the best, ending at 554 MB/s for reads and 519 MB/s writes.

The Toshiba THNSNH512GCST has some way to go before it becomes the go-to consumer choice. First in its marketing and retail availability, which are not quite in place yet; and in performance terms the Toshiba has a tougher job with stacked-up small file writes. In the 4kB read, and sequential reads, it puts in a marvellous show though.
