A-Data launches SATA 6Gb/sec SSDs

A-Data launches SATA 6Gb/sec SSDs

The A-Data S501 series includes a SATA 6Gb/sec interface capable of reaching up to 480MB/sec.

A-Data's long awaited S501 SATA 6Gb/sec SSDs have finally broken cover, bringing impressive read speeds to the 2.5in form factor thanks to a Marvell controller and speedy multi-level cell NAND flash.

The drives, which are available in 64GB, 128GB, 256GB, and 512GB, include 128MB of DDR3 cache and are clearly aimed at the high end of the market - in case the inclusion of a speedy SATA 6Gb/sec interface wasn't enough of a clue in that regard.

As you would expect, A-Data has tried to take full advantage of the increase in data transfer capabilities offered by the SATA 6Gb/sec interface, pushing the Toshiba MLC NAND chips to their limit via the Marvell-based controller and offering speeds of 480MB/sec read and 310MB/sec write - although the company warns that these figures will suffer if the drive is connected to a SATA 3Gb/sec controller.

While the speeds quoted by A-Data don't come anywhere near the impressive capabilities of PCI Express-based SSDs such as the OCZ RevoDrive X2, which can reach 740MB/s, they're impressive nonetheless - and come from a standard 2.5in form factor device which includes full support for performance-enhancing TRIM technology.

Although UK pricing hasn't yet been confirmed, European pricing is set at €170 for the 64GB, €259 for the 128GB, €489 for the 256GB, and €1099 for the top-end 512GB model - which translates to around £144, £220, £415, and £923 respectively, excluding VAT.

Do you think that A-Data's latest SSD range looks promising, or is the pricing way off? Have you been waiting for SATA 6Gb/s to make an appearance before jumping on the SSD bandwagon? Share your thoughts over in the forums.

That's actually really good pricing - we now have a 2.5-inch challenger to dethrone the C300! :)

512gb good capacity, but still way to pricey for mainstream

performance-enhancing TRIM technology.

Performance maintaining, surely?

These look good though, ~£220 for a 128GB single drive with this level of performance is already a pretty good deal, assuming UK prices aren't stupidly high. If I had SATA 6Gb/s I'd definitely go for one of these over a C300 (£205, 355/215) or a sandforce drive (£180, 285/275).

its funny how you mention the Revo as a comparison when just price a lone would make the A-Data a far better deal in terms of performance to storage for price.

I have my aim set to the 256GB SSD's, used to my 256GB HDD being OS drive so I won't settle for anything less. I'm only left with 2 options, go for the 1TB Spinpoint F3 while the SSD are prohibitive or SSD prices drop like Humpty Dumpty and I will treat myself for a Crucial C300 256GB or this A-Data 256GB

A 64GB C300 can be had for 90 pounds. Which is 50 pounds cheaper than one of these, Although they are faster.

Price excludes VAT so 128gb = £220 + 44 VAT = £264.

A bit too pricey for me considering I chose vertex 2e over c300 to save £35.

Would an add-on SATA6Gb/sec PCI-E card be required to obtain such high speeds? I didn't think current mobo's ports could provide the required throughput.

AMD Native Sata6 ports do (with C1E and C&N disabled) and some on board Sata 6 ports do as well problem is most motherboard makers have made Sata6 an tickbox item so most of them are very poor speeds even slower then the native chipset sata 3 ports, like they never bothered to even check to see if it works (its like they think an 1x pci-e 1.0 link (250mb/s) is really going to be plenty for Sata 600mb/s never mind two of them)

if you do get one make sure its an 2x or 4x sata 6 card
