Overall it was in the average range, but in the beginning of the test, it was one of the faster drives. The second generation 32-layer V-NAND comes in at 86Gbit or 10.75GB if you prefer the gigabyte form. This means buying larger capacity drives will give always you more for your money. Many PS4 enthusiasts are inclined to replace the stock hard drive of PS4 with a solid state drive (SSD), hoping for a huge performance boost like they see in computer systems when an SSD is used there. The proof is in the near-parity of the 850 Pro 2TB and 850 Evo 2TB; at best, the Pro version is about 15 percent faster than the Evo, and on average the difference is only about five percent. To see the best performance possible, the CPU C states have been disabled, C1E support has been disabled, Enhanced Intel SpeedStep Technology (EIST) has been disabled.
The high price of SSD is a drawback
Today we look at one of the first designed specifically for OEM customers ready to use SSDs as a marketing check-box in low-cost PCs. While the results of synthetic benchmarks are important to identify the key strengths and weaknesses of a drive, performance in these tests does not always translate directly into real-world situations. PS4 costs around $300 as of writing these words, whereas the cheapest 1TB SSD comes at around $200. I will be covering the reason behind that in more detail when we look at V-NAND more closely in the next few pages but as far as I know there has never been a strict rule as to why the capacities have scaled in powers of two. Choosing a good hard drive for PS4 can be wiser than going to an SSD for this purpose. It’s important to note that while the the SSD 850 Pro is faster than the SSD 850 Evo for the most part, in real-world usage, you might not notice at all. The second takeaway is that it’s really hard to justify buying any SATA drive right now other than the 850 Evo—it is a force to be reckoned with!
PS4 needs at least 1TB of space
Benchmarks for consumer testing are also benchmarks with a fresh drive so, not only can we verify that manufacturer specifications are in line but also, so the consumer can replicate our tests to confirm that they have an SSD that is top-notch. You can go for a 1TB SSD and replace the internal hard drive of PS4, but is this really worth it? Actually, we think that a PS4 SSD needs to be cheaper before it’s recommended for PS4 game consoles. The Z series, depicted above, serves the embedded market for products like digital signage and entry-level PCs currently populated by low-cost mechanical hard drives. To get a better idea how the SanDisk X400 will handle itself in the field, we will chart StorageMark 2010 HTPC, Productivity, and Gaming traces against comparable drives.
You may want then to go for an SSHD for your PS4, and this is a much better solution. I believe it is just a relic from the old days that has stayed in the memory industry because deep down binary is based on powers of two but the abnormal die capacity should have no effect on the operation of the NAND or the SSD as long as everything is optimized for it. The SSD 850 Pro’s 10-year warranty, however, is clearly better than the five-year of its sibling.
Which isn’t to say that the 850 Pro 2TB is bad; it’s just hard to justify spending an extra $200 for the small bump in performance. We even provide links to most of the benchmarks used in the report. Moving these machines over to SSDs makes them last longer, since they continue to perform well. Higher IOPS and MB/s rates with lower latency times are preferred. Due to the odd die capacity, the die configurations are also quite unusual.
