Hi David,
<div class=""><br class="">
</div>
<div class="">Each spinning platter drive can provide sequential data at ~150 MB/s</div>
<div class="">SATA SSD drives can provide data at ~600 MB/s, sequential or random</div>
<div class=""><br class="">
</div>
<div class="">If you have a 1Gb network connection, the max throughput is ~100 MB/s</div>
<div class=""><span class="Apple-tab-span" style="white-space:pre"></span>which would already easily be saturated by a 4 drive RAID 5</div>
<div class="">If you install a 10Gb card in the Synology and PC, max throughput is ~1 Gb/s</div>
<div class=""><span class="Apple-tab-span" style="white-space:pre"></span>which would need an 8 drive raid 5 to saturate with spinning platters</div>
<div class=""><br class="">
</div>
<div class="">So, for a 4-8 drive RAID 5 with a 10 Gb connection, SSD might provide some benefit regardless of application</div>
<div class="">For database operations (not image processing), SSD is worth considering in general</div>
<div class="">For 8-12 drive setups and image processing, spinning platters are fine</div>
<div class=""><br class="">
</div>
<div class="">It is also worth mentioning that SSDs can have longevity issues when run in RAID arrays, unless the controller knows they are SSDs and handles them differently.</div>
<div class=""><br class="">
<div class="">I have a 12 bay synology with spinning platters and a 10GB network card add-on, and for image processing operations, I can easily saturate the 10GB bus (close to 1 GB/s throughput). I haven't tested database operations.</div>

The question is simply: is the additional cost of SSD's inside the unit worth the extra money in terms of overall better performance? <span class="Apple-converted-space"> </span><br class="">
