PNY CS1311 SSD Review (120GB/480GB)

Yet again, we see a new entrant to the ultra-cheap, entry level SSD market. Aimed at those who are looking for a nice step up from a HDD, but have to pinch pennies, PNY has released a TLC packed contender, the CS1311. Designed to help speed up the computing experience for the everyday user, it isn’t the enthusiast class drive which we typically crave for, such as PNY’s CS2211 we just reviewed, but it is shouldn’t be overlooked simply due to the NAND it utilizes. With low price points and some decent performance numbers, the PNY CS1311 just might be one of the better TLC options out there. Let’s get on with the review and see how PNY’s latest SSD fairs!

PNY CS1311 SSD Main


The PNY CS1311 is a 7mm 2.5″ form factor SATA 6Gb/s SSD and is available in four capacities: 120GB ($49.99)240GB ($59.99), 480GB ($142.54), and 960GB ($283.47). Read speeds are rated for up to 550MB/s and writes for up to 520MB/s. In terms of IOPS these SSDs can deliver up to 9oK IOPS read/write. Quite impressive numbers for sure. Paired with a 3-year warranty, it is smack dab in the middle of the race against the competition.

The CS1311 also boasts a 2 million hours MTBF rating and its ECC corrects up to 120 bits per 2K sector. Full End-to-End Data path protection is supported as well as the ability to secure erase and on top of that, these SSD are validated to run in both RAID 1 and RAID 0.  In addition, the CS1311 now includes the Acronis data migration software, which allows for a seamless experience when transferring data from an existing drive to a new PNY solid-state drive.


Compared to the CS2211, the packaging is roughly the same. SSD form factor, capacity, model number and warranty is listed on the front as well as a feature stating that Arconis True Image is included. The back lists more specific details as well. Inside we can see that it also comes with a 2.5mm spacer for mobile systems with standard sized 2.5″ 9.5mm HDD bays.

The drive itself is encased in a black, metal shell. PNY designed the topside of the SSD to give it a sporty, carbon fiber aesthetic, which we quite like.

Once opened, we can see that typical Phison reference PCB designs. The 120GB model contains 4 NAND chips on a 3/4 size PCB and the 480GB model contains 8 on a full sized PCB. On both models we can see that the main components are all placed on the same side.

Both feature a Phison S10 controller, just as PNY’s enthusiast class CS2211. The difference with these SSDs is that instead of MLC NAND they utilize 15nm Toshiba TLC, which results in lower performance. Each NAND package is 32GiB in capacity for the 120GB model and 64GiB in capacity for the 480GB model, thus providing for 7% over provisioning. The 120GB model formats to 111GB while the 480GB model formats to 447GB.

Finally, we see they are utilizing Nanya DDR3L DRAM. For the 120GB model the package is 128MB and for the 480GB model it is 512MB and they operate at 800MHz.

    Thats a pretty good price for a 240G version. Too bad its for the states 🙂

    But 15nm TLC is worrying for me personally. Its bad enough we went sub 20nm, let alone 15nm. But hey, everything for that price/gb 🙂

    It seems that the “entry level, value oriented” ox is itself being gored by a matador named PNY. Its offerings are the first that I have seen that seem to attempt to give features in line with their price point. That, my friends, is value.

    I am not currently in the market for an SSD but I will be when Intel comes out with Generation 8 processors so I am following developments closely. I personally would go for the 2211 – pay more to get more – but the value is there in both of them.

    I have a few PNY items and they are fine. I made two purchases last month and had awful problems ordering through their website but it was easy to get genuine human interface and complete the order by phone.

    It seems that a lot of SSD manufacturers compete mainly against HDDs and not against each other. It seems that PNY is here to compete against both.

        The whole string was documented under the e-mail subject line “PNY Account will not accept my address”.

        It all was satisfactorily resolved at the time, albeit with considerable effort on the part of your people and me.

        I mentioned it here more as a disclosure/disclaimer.
