It doesn't review well, and Toms Hardware actually said the cheaper WD drive performs better.
The Crucial P5’s underwhelming application performance doesn’t help its value proposition. However, pricing, warranty, and endurance ratings are all reasonable. At 1TB and warrantied for up to 600TB of writes within five years, the P5 is well within the mainstream territory, but the company could have done more to compete with Phison based SSDS that are boasting incredible endurance ratings that are triple that of the P5.
While the P5 boasts quad-plane NAND and six Arm cores, the higher 512Gb NAND flash die density resulted in less die interleaving, and thus less performance than the competition at 1TB. The Samsung 970 EVO Plus blows the P5 out of the water with its thirty-two 256Gb NAND dies and penta-core Phoenix controller at 1TB, but the P5 is quite a bit cheaper based on capacity. At $150, Crucial’s 1TB P5 is reasonably priced for the performance it provides and is $40 cheaper than the 970 EVO Plus with similar encryption support, too. However, competition from other manufacturers is still very tough. At roughly $135-$140, we would rather recommend the Adata XPG SX8200 Pro or Gammix S11 Pro for those looking for a responsive gaming experience, although their SLC cache doesn’t recover nearly as fast as the P5’s after heavy write workloads and they lack encryption support.
If you need high-speed sustained write performance for media work, the
WD Black SN750 is a very good alternative that can sustain quite a bit of write abuse and is similarly priced, although like the P5, read performance lags a bit at low QDs and during small block requests.
For those looking to pinch pennies,
WD’s Blue SN550 may be a rather reasonable alternative that costs $45 less than the P5 and comes without the extremely slow write performance that most entry-level SSDs suffer from once its SLC cache exhausts. Even without the use of DRAM, WD’s Blue SN550 proved itself to be more responsive to application requests than Crucial’s P5. It even delivers faster game load performance and puts the P5 to shame when handling SPECworkstation’s prosumer workloads. While the P5’s design may be more robust than most, the performance results from today’s review speak for themselves.
