If you are looking for a budget-friendly SSD to upgrade from an old hard disk drive or to expand your existing storage space, PNY CS900 vs CS1311 are two great options. They both are priced very aggressively, and they both offer solid benefits. But, before you make your choice, know that PNY CS900 and PNY CS1311 have slightly different features.
Read the discussion below to learn about:
– The capacity options that are available on each line
– The NAND chips and controllers that these SSDs use
– The included software that comes with each SSD
– The performance of PNY CS900 vs CS1311
– Which PNY SSD that is generally better and more recommended
PNY CS900: Capacity Options
Since it was first released, PNY CS900 has been clearly aimed at the entry-level segment of the market. It comes at a very affordable price while offering all the typical benefits that you would expect from upgrading from an HDD to an SSD, such as faster boot-up and increased overall performance. It is backed by a 3-year warranty. See also: Crucial M500 Vs BX500
The affordability also makes PNY CS900 a viable choice for adding some storage space for your media files if your existing SSD is nearing its upper capacity limit. The company claims that PNY CS900 is up to 30x more robust than HDDs due to using non-moving parts. Also according to the company, PNY CS900 is compatible with Windows and Mac platforms, so it can be used on most computers in the world.
Initially, PNY CS900 was only available in three capacity options, which are 120GB, 240GB, and 480GB. However, rapid technological advancements have allowed the company to add a new capacity option, 960GB, to the line. Being entry-level models, their prices are comparatively lower than most other competitors.
PNY CS900: Features
If we compare the features of PNY CS900 vs CS1311, we will see that they look similar. Each has the usual 2.5-inch form factor. Each of them also comes with a 7mm-thick enclosure which makes them compatible with modern notebooks which require low-profile drives, but a 9mm adapter is also included for compatibility with full-sized systems. Yet, some of the internal components do differ. While PNY CS900 is a good entry-level SSD, it is not as sophisticated as PNY CS1311.
PNY CS900 comes with the 6Gbps SATA interface, but it is somewhat late to get into the game as other companies have introduced SATA-based SSDs in the 1TB range and higher. This simply reinforces the idea that PNY CS900 is strictly for budget-conscious users. If you are willing to spend a little bit more money without being prodigal, PNY CS1311 does have 1TB and 2TB options.
Nevertheless, the build quality of PNY CS900 is reassuringly good. It is lightweight and shock-proof, and being an SSD comes with the perk of having no moving parts. As a result, PNY CS900 is indeed much more robust and durable than HDDs, so you won’t need to worry about sudden breakdowns. The 3-year warranty also indicates the company’s confidence in the build quality of the product.PNY CS900 is armed with triple-level cell (TLC) NAND flash memory chips – something to be expected from an entry-level SSD. In other words, each cell in the drive is used to store three different bits of data. Meanwhile, a multi-level cell (MLC) chip only stores two bits of data per cell, and a single-level cell (SLC) chip only stors one bit of data per cell.
The first and foremost advantage of using TLC chips is the low cost. By using TLC chips, PNY CS900 can have a large capacity while keeping the price tag low. However, TLC-based SSDs like PNY CS900 vs CS1311 are less robust and often less powerful than their MLC-based or SLC-based counterparts, such as the gaming-oriented PNY CS2211.
PNY CS900 doesn’t come with many additional features; there is no encryption engine or security software. The only included software is the Acronis True Image HD for data migration. It is quite useful for transferring files quickly from the old drive to the new drive.
PNY CS900: Performance
The performance of PNY CS900 is somewhere in the medium-low range. It is nowhere as fast as the more expensive SSDs, like PNY CS2211 or Samsung 860 Evo. However, compared to the products in the same price range, PNY CS900 is able to fare pretty well. The balance between affordability and performance versus HDDs is great.
According to the specs, PNY CS900 has a sequential read speed of 535MB/s and a sequential write speed of 515MB/s. The random IO performance is not mentioned, so it is most probably the weak point of this SSD. When tested with mixed random IO tasks, the average speed is about 29.7MB/s. Not too bad, although obviously nowhere near the best.
Compared to PNY CS1311, the performance of PNY CS900 is also slightly lower. PNY CS1311 has slightly higher sequential read and write speeds, and it also delivers a higher average speed when doing mixed random IO tasks. The differences in the numbers are pretty small, but an advantage is still an advantage.
PNY CS1311: Capacity Options
PNY CS1311 is just like PNY CS900, in the sense that it is meant to be a budget-friendly choice for upgrading from an old HDD or expanding an existing storage space. However, PNY CS1311 has been equipped with a new direct-to-die algorithm from Phison, which improves its performance quite a bit.The company has marketed PNY CS1311 like they do with PNY CS900, by comparing its performance and robustness to HDDs. This is understandable because of the target segment of PNY CS1311. But, because of that, the difference between PNY CS900 vs CS1311 becomes vague and not apparent right away.
From the capacity perspective, PNY CS1311 has more options. It is available in 120GB, 240GB, 480GB, 960GB, and 2TB. So, if you need a huge amount of storage space for films, music, or games, getting the 2TB version of PNY CS1311 is an excellent idea.
PNY CS1311 is also compatible with Windows and Mac platforms, and is backed by a 3-year warranty. It also promises quiet operation, minimal heat, and low power consumption.
PNY CS1311: Features
In the early days of SSDs, Samsung was the only one who could make TLC-based SSDs with good performance. Other products from other companies were slow; not all applications suffered, but large software installations could take forever to complete. Some TLC-based SSDs even dropped their sequential write speeds to 70MB/s during such tasks.
Phison was the first controller vendor besides Samsung who addressed the issue with the direct-to-die algorithm, and PNY CS1311 was among the first to use this technology. In the direct-to-die algorithm, the controller puts the sequential data into the SLC buffer first, and then writes them directly into the flash memory chips. By writing directly into the flash memory chips instead of waiting for the buffer to fill and purge, the sequential write performance can be a lot faster.
Besides that, PNY CS1311 also comes with a revamped look. Well, appearance doesn’t really affect performance, but some people just can’t resist the charm of a good-looking piece of hardware. PNY CS1311 comes with a black-colored metal chassis with a glaring red line decorating the top side.
This model also comes with a 2.5-inch form factor and the 6Gbps SATA interface. It has a 7mm-thick enclosure, meaning that it can fit into thin notebooks just fine, with a 9mm adapter included for compatibility with full-sized systems. Just like PNY CS900, PNY CS1311 comes with the Acronis True Image HD for data migration, which will allow you to transfer files from your old drive to the new one easily.
PNY CS1311: Performance
As usual, the performance across the different capacity sizes varies a bit. However, in general, PNY CS1311 is slightly faster than PNY CS900. The sequential read speed is steady at 550MB/s, whereas the sequential write speed is around 510MB/s for the lowest capacity and 530MB/s for the highest capacity.
The random IO performance is also better. When handling mixed random IO tasks, PNY CS1311 has an average speed of 36.9MB/s, which is notably faster than the majority of the competitors of the same class. The 4K random read speed at QD32 is 80,000 IOPS, and at QD4 is 20,000 IOPS. The 4K random write speed is more stable, 40,000 IOPS at QD32 and just over 30,000 IOPS at QD1.
The overall performance of PNY CS1311 has placed it in the middle class in the market. The aggressive pricing makes it a very valuable pick if you want to get the most out of your money. This is a solid choice for upgrading from an old HDD or for storing games and media files.

Between these two models, PNY CS1311 is much more recommended. It comes with the new Phison algorithm that enables faster overall performance. It is faster in both sequential and random operations. Additionally, it has more capacity options, with the 960GB and 2TB models being particularly attractive for storing games and media files.
