Equivalent specs to Samsung's 840 PRO SSD and at a great price of SGD$400! Still under warranty!
Prefer to deal in West areas.
PM for queries, specs as follows;
With specs like these, the Plextor M5 Pro Xtreme competes toe-to-toe with the Samsung 840 Pro Series. Plextor is advertising sequential read speeds of up to 540 MB/s and sequential write speeds of up to 470 MB/s with the help of a SATA III interface (6 GB/s). The 4K random read/write speeds are just excellent, at 100,000 IOPS and 88,000 IOPS.
The M5 Pro Xtreme comes in three capacities: 128 GB, 256 GB and 512 GB. The 128 GB has slightly lower read/writes (540 MB/s and 330 MB/s, respectively) than the others. We tested the 512 GB.
The Plextor M5 Pro Xtreme uses a Marvell 88SS9187 controller, which has a 128-bit error correction system and 256-bit AES encryption to protect sensitive data.
It features Toshiba's 19nm Toggle MLC NAND flash memory, which gives it enough lifespan to have a five-year warranty. Advertised at 3,000 write cycles per cell, the estimated lifespan for a user who works 8 hours a day on their computer (10 GB) is 421 years, or 210 years for an intensive user (20 GB per day). But these figures are only so reliable, in that flash memory makers themselves don't even guarantee that the data will still be around after 10 years.
The 2.5-inch casing is only 7 mm thick and weighs 56 grammes. At that size, it can fit into any laptop that has a 2.5-inch slot. And for desktops Plextor includes a 3.5-inch adapter in the box. We approve!
Like the Samsung 840 Pro, the M5 Pro Xtreme doesn't use any special processes like over-provisioning, on-the-fly compression or first-level writing on cells.
The advantage the Marvell 88SS9187 presents over other controllers is that it's capable of retrieving the SSD's original performance simply by formatting the disk.
The rates we measured on the M5 Pro Xtreme were extremely high—but still not as high as the 840 Pro. Using a benchmark we got 496 MB/s reads and in practice we got 455 MB/s (compared to 517 MB/s and 484 MB/s on Samsung's drive).
When it comes to sequential write speeds, that's where you see a bigger difference between the two. We measured the Plextor at 436 MB/s using a benchmark and 596 MB/s in practice—which is 10% slower than the 840 Pro.
But with installing and launching apps, this Plextor and the Samsung Pro are equally fast.
Accessing programmes: 4K random access
The random access speeds are also slower than the 840 Pro. With 56 MB/s writes and 26 MB/s reads on small files (4 KB), the M5 Pro Xtreme lags slightly behind, but it's still faster than most solid-state drives—in fact, it gets just about the same speeds as the Intel 520 Series.
And either way, it's still miles ahead of an ordinary HDD.
The M5 Pro Extreme 512 GB is an excellent SSD from Plextor, and it has a five-year warranty. It's one of the fastest drives on the market, although it's still a dash slower than the Samsung 840 Pro Series. One of our only complaints is that, unlike Samsung, Plextor doesn't include any software with the drive.
