![]() The 15nm stuff does cost less to manufacture, though.Condusiv Technologies is an American software company based in Burbank, California. We've tested other products armed with A19 and 15nm flash, and they perform similarly. ![]() OCZ also told us that the RevoDrive 400 will ship with Toshiba 15nm MLC flash. OCZ already mentioned that its RevoDrive 400 will have different firmware perhaps the updated software increases the controller's operating frequency. Because this is an OEM drive built specifically for notebooks, it may run at lower clock rates to avoid throttling. Heat wasn't a problem during testing, but our test platform also offers better-than-average airflow over the SSD. The XG3 uses a new four-lane PCIe 3.1 NVMe controller. And while we've yet to run into an issue, we expect to at some point. Ultrabooks leave very little room between the motherboard and chassis. This actually becomes an issue with some notebook upgrades, and is part of the M.2 specification. A Closer LookĪs mentioned, the three lower-capacity XG3s employ a single-sided configuration, while the 1TB model places components on both sides of the PCB. Samsung and Intel both ship model-specific drivers to improve performance in Windows, so perhaps Toshiba has something in the works. Fortunately, Microsoft enables basic support in Windows 8.x and 10, though. We were not able to find a Toshiba-specific NVMe driver for the XG3, even after searching MSI's support site for notebooks shipping with the drive. Company reps had the utility running with a RevoDrive 400 on display at CES. But we learned that OCZ's SSD Guru management utility will support the RevoDrive 400. The XG3 does not ship with a software package. At CES, OCZ told us its RevoDrive 400 will compete with Samsung's 950 Pro and that it should sell for a little less. We do not know what Toshiba charges its customers, or what the RevoDrive 400's MSRP will be. We paid $80 for a 128GB XG3 M.2 drive, but that's a spot market price. Many of them are so good that we often find them in servers. This may be due to availability, because Toshiba has several very good OEM SSDs. ![]() Toshiba's OEM products don't enjoy the cult following that Samsung's SSDs do. In a later article, we will test several new NVMe M.2 SSDs for power consumption in our notebook battery life suite. ![]() We have a pair of NVMe-capable notebooks en route for power testing, but they're not here yet. Three years ago, PCI-SIG announced version 3.1 of the PCIe spec, introducing a L1 low-power state, CLKREQ# signal and a separate REFCLK with independent SSC architecture. The highest-capacity model has components on both sides of its PCB, while the three smaller ones fit everything on one side. This is a new model, and most drives are in expensive new notebooks. This is similar to the way other vendors with NVMe SSDs determine random performance for their marketing material.Īgain, the XG3 is available at four capacity points, but the three largest are like Sasquatch-I know a guy who claims to have seen one, but the pictures are all grainy and out of focus. We couldn't find any specifications on random performance, so we generated our own using four workers at a queue depth of four to get a 16 Outstanding Input Output rating. The only real performance information is cherry-picked from the largest model, yielding an up-to ceiling for all four capacities. Toshiba hasn't published a lot of information about its XG3 NVMe SSD.
