The wee M.2 2242 form factor of the RC100 means there is no space for a DRAM buffer, which led Toshiba to utilize the Host Memory Buffer feature included in NVMe revision 1.2. In order to use this feature you must be running Windows 10 Fall Creators Update (or 1709) or the at least the 4.14 Linux kernel. It commandeers a portion of your system RAM to act as the cache, somewhat less effective than having it on board as The Tech Report's testing shows. As well it is hampered its PCIe 2x interface, which ensures it falls behind 4x NVMe drives.
The testing reveal the weaknesses of this design, but it is an interesting implementation of an NVMe featuer not often seen, which is in itself worth taking a look at.
"Toshiba's RC100 NVMe SSD takes a bold stab at life without DRAM or a full four lanes of PCIe connectivity. Unlike many DRAM-less SSDs, however, the RC100 has a trick up its sleeve with the NVMe protocol's Host Memory Buffer caching feature. Join us to find out whether NVMe and HMB can bolster this entry-level SSD's performance."

Toshiba RC100 240GB/480GB SSD Review
Budget SSDs are a tough trick to pull off. You have components, a PCB, and ultimately assembly - all things which costs money. Savings can be had when major components (flash) are sourced from within the same company, but there are several companies already playing that game. Another way to go is to reduce PCB size, but then you can only fit so much media on the same board as the controller and other necessary parts. Samsung attempted something like this with its PM971, but that part was never retail, meaning the cost savings were only passed to the OEMs implementing that part into their systems. It would be nice if a manufacturer would put a part like this into the hands of regular customers looking to upgrade their system on a budget, and Toshiba is aiming to do just that with their new RC100 line:
Not only did Toshiba stack the flash and controller within the same package, they also put that package on an M.2 2242 PCB. No need for additional length here really, and they could have possibly gotten away with M.2 2230, but that might have required some components on the back side of the PCB. Single-sided PCBs are cheaper to produce vs. a PCB that is 12mm longer, so the design decision makes sense here.
Bear in mind these are budget parts and small ones at that. The specs are decent, but these are not meant to be fire-breathing SSDs. The PCIe 3.0 x2 interface will be limiting things a bit, and these are geared more towards power efficiency with a typical active power draw of only 3.2 Watts. While we were not sampled the 120GB part, it does appear to maintain decent specified performance despite the lower capacity, which is a testament to the performance of Toshiba's 64-layer 3D BiCS TLC flash.
Not much to talk about here. Simple, no frills, SSD packaging. Just enough to ensure the product arrives undamaged. Mission accomplished.

Toshiba announced a couple of new additions to their SSD lineup. First up is the RC100:
This is a DRAMless design intended to target budget builds - something much needed in the current (pricey) SSD landscape. Just because there is no DRAM present in the design does not mean that the RC100 can't perform well. Toshiba has implemented the Host memory Buffer (HMB) feature, which allows the NVMe driver to share a small (38MB) portion of host memory via the same PCIe 3.0 x2 link used to transfer user data. This memory portion effectively caches a portion of the FTL, which should bring the random performance of smaller sections of the SSD up to what you would expect to see from a higher performance product. Specs are as follows:
- Capacities: 120/240/480GB
- PCIe 3.0 x2
- Random read/write: 160/120k IOPS
- Sequential read/write: 1620/1130 MB/s
- Warranty: 3 years
Up next is the XS700, Toshiba's first portable SSD:
- 240GB only
- USB 3.1 Gen2 (type-c connector on device)
- Ships with type-c to type-a cable
The XS700 is the first portable SSD I've seen out of Toshiba. It was just a matter of time here as just about every other major SSD maker has offered a similar product.
We don't have pricing yet, but these should shape up to be highly price-competitive products offering decent performance. Both models will be coming later this year.
Press blast after the break.
