Sandisk Ultra Plus Vs Extreme

Many people are moving to SSD for the many plus sides on this drive compare to hard drives, such as more efficient in terms of energy use, quiet, more durable, and of course faster everything, which is why computer with SSD boots and shuts down very fast as well as can resume from sleep mode instantly. In today Sandisk Ultra Plus Vs Extreme article, we are going to compare both of these solid state drives to give you more information regarding what you can expect from them.

In this article, we are going to give you information about:
– What are SanDisk Ultra Plus and Extreme
– What SanDisk Ultra Plus and Extreme can offer to you
– SanDisk Ultra Plus vs Extreme

About SanDisk Ultra Plus
SanDisk is a very popular solution for almost any devices that use NAND. There are just so many of them in the market and one of them is included in a Cortex A15 based Chromebook. Just like other manufacturer like Micron/Intel, the company jointly and develop as well as manufactures its own NAND with Toshiba. Even though they are prevalent in the OEM market, somehow they are not that popular in end-consumer but the company wants to change that situation with the release of Ultra Plus.

SanDisk Ultra Plus Features
Just like many other manufacturer that adopted SandForce controller, SanDisk also use a controller from another manufacturer, which is Marvell. Taken from CNET, the Ultra Plus itself is based on Marvell’s SS889175 Gbps SATA/NAND controller. This controller is apparently the light version of 9174 that you can find in Plextor’s M3 and Intel SSD 510 that has a focus in reducing power consumption. It now features 4 independent NAND channels, which probably the key to reduce its power consumption.

The company decision to use Marvell controller may base on how it is more affordable than SandForce and the direct access they get to the firmware source as well as the ability to develop their own from scratch. The drive comes with 19nm Ex2 ABL MLC NAND, which is 2-bit MLC NAND with a twist. The twist here is there is a portion of the NAND array that operates on SLC or pseudo-SLC mode called nCache and the firmware can define how much of the NAND is used as an nCache.

The Ultra Plus is equipped with 128MB Samsung DDR2-800 DRAM. When tested, the drive seems to deliver good performance but lesser if compared to other drives with the same range of price. In terms of performance consistency it can be better than that 840 Pro even in worst case, so you may want to leave at least 25% of the drive if you want to avoid annoying performance variation. Overall, it able to deliver a decent performance way far better than a hard drive with reasonably low power.

However, since it is not that good compared to the rivals that comes in similar price range, you may want to consider your choice. But, if low power consumption is your concern, the drive will probably suit your need. In present day, it is priced around $124 for the 128GB capacity, which means it will be 96 cents per GB with a 3 year limited warranty to make sure your drive will serve its purpose properly.

About SanDisk Extreme
If you think the price for Ultra Plus is too high, why don’t try the Extreme model. This drive is released earlier around a year than the Ultra Plus but still available today if you just want an affordable option for a regular home-used SSD. It may not that good if you compared the drive with newer releases in few years back, but it is still a good drive that claims to be able to reach sequential read up to 550MB/s and write performance up to 520MB/s with its SATA 6Gbps interface.

SanDisk Extreme Features
The SanDisk Extreme comes with a controller from SandForce, which is the SF-2281, but there is something new here in the form if its own 24nm Toggle Mode NAND. When you open and look the drive inside (we are not advising to do it for it can void your warranty), you can see the controller accompanying Toggle Mode NAND memory chips. The 120GB drive will have 24nm chips and if you own the 240 capacity, there should be four pieces of 32GB NAND on each side of the PCB. If they squeeze them tight enough, they can fit another 8 memory chips.

The combination of SandForce 2281 controller with Toggle Mode NAND are already seen in Patriot’s Wildfire and able to deliver excellent result, but since now they put higher density 24nm chips, there will be less NAND devices communicating with the controller in parallel. These combination itself already look attractive with the price point at that time. There is also a package with 3.5 inch mounting adaptor in case you want to put it in your computer but they still don’t include disk migration software.

When tested, the drive proved to be able to live up its claim and even better. When compared with drives that come with the same controller at that time, the SanDisk Extreme still perform better probably because of the type and quantity of NAND. Its Toggle mode beats synchronous while synchronous beats asynchronous and of course the more chips the better.

In present day, the drive is priced around $143.95 for the 240GB capacity, which makes it down to 59 cents per GB. It may not the cheapest drive today, but it is undeniably affordable and with the good performance, it can be a good option to replace your hard drive. Similar like Ultra Plus, it also has 3 years limited warranty.

Now, let’s compare SanDisk Ultra Plus with Extreme. From the performance, we can say that the SanDisk Extreme is better than Ultra Plus in almost every test, but the difference is very small. Another thing that separate them from each other is the controller for Ultra Plus use Marvell’s 9175 while Extreme comes with SandForce 2281.

Sandisk Ultra Plus Vs Extreme

- Operating temperature: -32 Degree F to 158 Degree F (0 Degree C to 70 Degree C)
- Increased performance for faster boot and application load times
- Increased reliability and durability over traditional hard drives
- Consistently high data transfer speeds
- Noise reduction for quiet drive operation
- Low power consumption for cooler operation and extended battery life
- Delivers reliability, durability, and high-performance for your laptop or PC
- Designed to withstand shocks and vibration for high durability

All in all, the decision is all yours to make. Since the performance are quite similar even though Extreme is better, you may not notice the difference in real world. However, when taking their price into consideration, we will highly recommend you SanDisk Extreme for not only it is better, it is also more affordable than Ultra Plus.
