Why would you want to put around 50TB of storage capacity in a DSS200 (8 x 8TB drives in a RAID5 configuration)? OK, a DSS200 can be used as a mini TMS for, if memory serves me correctly, three or four screen servers, but even that wouldn't need anything approaching that capacity. The biggest TMS I've ever encountered had 24TB of usable capacity, and that was in a unique situation (a post house that had to deal with a huge amount of content).
In 2014, I followed Brad's suggestion and installed the 8-port 3Ware RAID card plus 8 x 2TB drives into one, but in those days the cost of bigger drives was such that this was the most cost effective way to buy 13TB of usable capacity; and the big festivals we were doing, some of them back-to-back, meant that we needed that. Not any more, though: if I were in the same situation now, I'd use 4 x 4TB.

I didn't notice the L, either - sorry.
From what I can see looking inside them, the differences between the DSS200 and the DSL200 are that the DSL has a different model of RAID card (3Ware 9750-8i, which has a backup battery on it) and no cat862 media block in it: otherwise, they're the same machine.
If you use the optional SAS card on a DSL200, you can boost the total space available beyond 16TB, but only because you're then using two separate filesystems (the onboard content RAID and the external one).
Still, 50TB on a single TMS? I suppose if you're running a 30-plex, with all the screens playing 3-hour long, 4K, HFR features, you'd be approaching that sort of capacity requirement, but not unless.

You'd be surprised at how quickly TMS space gets used up when you deal with 2D, 3D, 6fl 3D, Laser 3D, Atmos, Auro, DTS-X, Dolby Vision, and IMAX.
And then add in the 17,238 trailers for [pick a tentpole] with a different version of each of those trailers for every 3D and "PLF" format out there, plus some chains get preferential branding and those get sent out to everyone.
If you have DCDC, you can expect today to have this week's titles, next week's titles, and later tonight they'll start to delivery the following week's titles.
Sometimes you get both Interop and SMPTE versions of a title, and you can't delete one because who know what keys they'll send next week.
Don't get me started on special events, promo screenings, or classic film series!
