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 ||Cons |
Summary and Score
The 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.

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.
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|
|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|
|CDM 3 Write||Seq||512K||4K||4K QD32|
|Samsung 850 Evo M.2||474||394||113||316|
|Samsung 850 Evo||504||479||68||352|
|Samsung 840 Evo||500||390||86||313|
|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|
|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|
|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.
|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|
|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|
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.
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.
