Sandisk Z410 SSD review: an ideal low-cost upgrade

Z410_AngledView_678x452

Sandisk is one of the best known names when it comes to flash memory, and their latest drive is the Z410. This drive is intended for enterprise use, as a cost-effective upgrade from older SSDs or mechanical drives. Thanks to Zoostorm and Sandisk, we’re able to put it to the test!


Pros

  • Way faster than a mechanical HD
  • Good sequential read/write performance
  • Reasonable value of £0.25/GB
Cons

  • Poor random read/write performance

Summary and Score

score8-gif-200The Z410 is a low-cost SSD with good sequential speeds, both reading and writing, but worse random performance than high-end consumer drives. If you’re looking for a cheap upgrade to an old SSD or (gasp) a mechanical drive, this is a good shout if you can find it for a low price.

Benchmarks

We’ll be testing the Z410 against the Samsung 850 Evo and 840 Evo, plus the Corsair Neutron GTX from 2012. These are top of the line enthusiast-focused drives, so it’ll be a tough test for this enterprise-focused, low-cost Sandisk drive.

We’ll be testing the drive in our new test rig, which has a Core i5 6600K processor, 16GB of Crucial DDR4 RAM and runs Windows 10.

Thanks to NZXT for providing the Manta case and Kraken X61 liquid cooler. Thanks to Samsung for providing the Evo 850 M.2 boot drive. Thanks to Zoostorm and Crucial for providing the DDR4 RAM.


CrystalDiskMark

CrystalDiskMark has been one of my favourite benchmarks for evaluating storage speeds for a while now, thanks to its varied incompressible workload and extremely readable results. Here’s the 3.0.3 x64 version of the benchmark; all results are in MB/s.

CDM 3 Read Seq 512K 4K 4K QD32
Sandisk Z410 508 357 13 146
Samsung 850 Evo M.2 502 447 45 368
Samsung 850 Evo 513 472 38 408
Samsung 840 Evo 515 473 35 397
Corsair Neutron GTX 450 376 27 328

Corsair Neutron GTX 480 468 69 158

The Z410 shows reasonable sequential performance, but relatively worse results as block size is decreased. Speeds when reading or writing 4K blocks are particularly poor. This underlines the importance at looking at the full benchmark — it’d be tempting to look at sequential results only and dub this a very fast drive, but it’s not the whole picture.


AS SSD Benchmark

AS SSD is another benchmarking tool quite similar to CrystalDiskMark, which uses predominantly incompressible data across a range of workloads including sequential tests, random performance and access times. First three numbers are MB/s and access time is in ms.

AS SSD Read Seq 4K 4K QD64 Acc. Time Score
Sandisk Z410 501 11 145 0.045 206
Samsung 850 Evo M.2 493 40 328 0.093 417
Samsung 850 Evo 516 34 382 0.059 467
Samsung 840 Evo 513 32 330 0.059 413
Corsair Neutron GTX 507 25 334 0.068 N/A
AS SSD Write Seq 4K 4K QD64 Acc. Time Score
Sandisk Z410 407 78 215 0.237 333
Samsung 850 Evo M.2 475 95 251 0.075 393
Samsung 850 Evo 497 66 299 0.051 415
Samsung 840 Evo 497 69 207 0.054 326
Corsair Neutron GTX 473 62 295 0.062 N/A

Once again, the Z410 displays reasonable read and write speeds in sequential tests, but performance while reading small 4K blocks, a task that commonly occurs on booting a system and in some games (depending on how they’re designed), is atrocious. The access times measured are also interesting, being very very good in reading, and very very bad when writing.


ATTO Disk Benchmark

ATTO produces rather less comprehensible results than CrystalDiskMark, but still provides a good test of compressible data transfer. It also provides a lot of data points; I’ve selected six from across the range. Settings were the default: 256MB total length and queue depth of 4, testing from 1KB to 8MB. All results are in MB/s.

Atto Read 1KB 4KB 64KB 256KB 1MB 8MB
Sandisk Z410 78 247 518 531 536 533
Samsung 850 Evo M.2 83 286 537 553 552 553
Samsung 850 Evo 80 269 538 551 558 558
Samsung 840 Evo 94 280 535 551 555 555
Corsair Neutron GTX 15 61 336 452 530 540
Atto Write 1KB 4KB 64KB 256KB 1MB 8MB
Sandisk Z410 69 184 419 423 426 428
Samsung 850 Evo M.2 79 251 510 526 525 525
Samsung 850 Evo 83 255 519 529 534 534
Samsung 840 Evo 81 260 515 527 533 534
Corsair Neutron GTX 15 142 474 470 493 498

Trends continue in the ATTO benchmark, with the drive showing decent performance at high block sizes, and worse performance at lower sizes. The drive is purportedly designed for enterprise use, so it’s likely that sequential speeds were prioritised over random access.


HD Tune Pro

We conclude with HD Tune Pro, a benchmark which produces three scores for average read speed, read access time, and burst read rate.

HD Tune Pro 5.50 Read Average Access Time Burst Rate
Sandisk Z410 358 MB/s 0.035 ms 140 MB/s
Samsung 850 Evo M.2 321 MB/s 0.087 ms 221 MB/s
Samsung 850 Evo 370 MB/s 0.044 ms 250 MB/s
Samsung 840 Evo 358 MB/s 0.041 ms 231 MB/s
Corsair Neutron GTX 340 MB/s 0.059 ms 231 MB/s

Screenshot 2016-05-30 15.31.06

The average speed here is quite strong, with a maximum around 425 MB/s, and access times are also excellent. Burst rate is around 60% the speed of every other drive we’ve tested, but still well above the average mechanical drives the Z410 is designed to replace.


 

Wrap-up

The Z410 doesn’t compare to high-end consumer SSDs from Corsair, Samsung and others, but that’s OK! This is a low-end SSD, which still manages to provide a noticeable speed boost over older SSDs and all mechanical hard drives.
